In this document the Bishop of<br> Paris, Stephen Tempier, declares that certain masters<br> in the Parisian Arts Faculty “hold that something is<br> true according to philosophy but not according to the<br> Catholic faith, as if there are two contrary truths, and<br> as if in contradiction to the truth of Sacred Scripture<br> there is a truth in the doctrines of the accursed pagans.”<br> The same proposition may be true and false simulta-<br> neously, true in philosophy and false in theology—such<br> is the condemned doctrine of double truth. Unready<br> to accept this denial of the law of contradiction, which<br> he sees as a device to assert heresy, the bishop then<br> lists 219 condemned errors. The masters of arts are<br> warned not to teach them on pain of excommunication.<br> Although the thirteenth-century Averroist Siger of<br> Brabant, and his contemporary Boethius of Dacia are<br> the only two masters mentioned by name in the con-<br> demnation, the list of heterodox propositions is so broad<br> that it includes doctrines taught by Saint Thomas.</div> <div class="para">In two senses the condemnation represents a crisis<br> in the Western Latin mind. In the narrower sense, it<br> is an attempt on the part of the Parisian Faculty of<br> Theology to stop philosophical speculation in the Fac-<br> ulty of Arts, especially when that speculation abandons<br> the traditional guidance of theology and openly pro-<br> fesses heterodox doctrines. At the time of the orga-<br> nization of the University in 1200, the greater part of<br> Aristotle's works was already available in Latin trans-<br> lation. As the higher of the two faculties, the Faculty<br> of Theology wished to assert its control over the study<br> of these new doctrines, particularly the dangerous ideas<br> found in the <i>libri naturales</i> and the <span class="italics">Metaphysics.</span> From<br> the very beginning theologians were suspicious of their<br> contents. In 1210 and again in 1215 the public and<br> private teaching (though not private reading) of Aris-<br> totle's works was banned at the University. Yet the<br> theologians themselves soon began to be impressed<br> with the tremendous power and comprehensiveness of<br> Aristotle's doctrines, and in 1231 Pope Gregory IX<br> decided that Aristotle might be taught at Paris if his<br> errors were first expurgated. With this limited ap-<br> proval, the knowledge of Aristotle increased and by<br> 1243 the commentaries of Averroës became known.<br> Although the ban against an unexpurgated Aristotle<br> was still in effect at the University in the 1240's, it<br> was not always upheld. For example, in 1245 Roger<br> Bacon lectured in the Arts Faculty on the complete<br> <span class="italics">Physics</span> and <span class="italics">Metaphysics.</span> Nevertheless conflict did not<br> break out between the two faculties, probably because<br> the masters of arts continued to quote Saint Augustine<br> with respect, and to dismiss discreetly any heterodox<br> doctrine of Averroës or Aristotle. When the split finally<br> opened in the 1260's, the cause was not difficult to<br> find. Led by Siger of Brabant, the masters of arts were<br> openly professing heterodox Arabic-Aristotelian con-<br> cepts in disregard of the doctrines of revelation. Thir-<br> <div class="pb"> Page 32, Volume 2</div> teen doctrines, condemned in 1270, were included in<br> the great condemnation of 1277.</div> <div class="para">In the larger sense, the condemnation represents<br> more than the professional rivalry of two faculties. For<br> the theologians were the guardians of the Augustinian<br> tradition which had been dominant in medieval<br> thought up to this time. Augustinianism had made its<br> peace with pagan philosophy by absorbing the spiritual<br> orientation of Neo-Platonism while subordinating it to<br> Christian revelation. The Augustinian universe consists<br> of a static, hierarchically ordered series of beings cul-<br> minating in the Supreme Being who has created all<br> from nothing. Through his omniscience, the Divine<br> Being knows all; through His mercy He provides for<br> all; through His freedom He orders all to His will. The<br> Arabic-Aristotelian view, now championed in the Fac-<br> ulty of Arts, stands in dramatic opposition to this. The<br> universe is moved by the Prime Being, the first of the<br> separated Intelligences. Emanating from this Intelli-<br> gence are the other Intelligences, the heavenly spheres,<br> and finally the earth as the arena of generation and<br> decay. The entire emanation proceeds by an eternal,<br> necessary movement, controlling the Prime Mover<br> Himself. Such a God can only produce an effect similar<br> to Himself: a unique, undifferentiated substance. The<br> multiplicity of effects in the world, then, presupposes<br> the multiplicity of intermediary causes, rather than the<br> direct activity of God. It follows that God acts through<br> the heavenly Intelligences which in turn produce the<br> multiplicity of things on the earth. The Intelligences<br> thus become the immediate causes of earthly effects.</div> <div class="para">Here then we have a dramatic contrast: a free,<br> personal deity as opposed to an impersonal deity<br> moved by necessary causes; a created universe as op-<br> posed to an eternally emanating one; a knowing God<br> as opposed to one who knows only himself; a being<br> who acts directly on the earth as opposed to one<br> who acts through the intermediaries of the Intelli-<br> gences.</div> <div class="para">To illustrate this crisis more concretely and to show<br> the origin of the doctrine of double truth, we must<br> isolate several of the condemned propositions. As we<br> have seen, Aristotle and Averroës held the eternity of<br> the world; it was moved by a Prime Mover who acti-<br> vates necessarily the Intelligences of the heavenly<br> spheres. This denied creation <i>ex nihilo</i> of Genesis, and<br> the freedom and providence of a personal deity. More-<br> over, an eternal movement is constant and absolute,<br> and the nature produced from such a movement ex-<br> hibits the same features: there can be no interruption<br> of the laws of nature. Hence there can be no miracles<br> performed by a personal God or His messengers.</div> <div class="para">In the second place, Aristotelian psychology, at least<br> as interpreted by Averroës, denied the immortality of<br> the individual soul. For Averroës the only immortal<br> soul is a divine intellect which at times unites itself<br> to man. This union produces an “acquired intellect”<br> which gives man the power to know. As the title<br> “acquired” makes clear, this intellect—the only human<br> one which knows—is not intrinsic to man. In other<br> words the intellect for man is not an inherent form<br> but an assisting form. Since the “acquired intellect”<br> is produced only when the vegetative and sensitive<br> functions operate, their cessation at death entails the<br> destruction of the “acquired intellect” and the whole<br> human soul. Only the divine intellect remains and is<br> immortal. It is the one, true intellect for all men. This<br> is the famous doctrine of the unity of the intellect,<br> a doctrine which destroys the Christian concepts of<br> personal immortality, salvation, and resurrection.</div> <div class="para">Finally, other condemned ideas attack the very basis<br> of the Christian religion by asserting that philosophy<br> is the highest wisdom. In contrast, Christianity is pic-<br> tured as containing falsehoods “like all other religions”<br> and is held to be based on myths and fables. Although<br> the notion that philosophy is the supreme wisdom is<br> found in some thirteenth-century thinkers, the idea that<br> Christianity is false or mythical only appears for the<br> first time with John of Jandun in the early fourteenth<br> century.</div> <div class="para">What did the masters of arts actually say in profes-<br> sing these doctrines of the “accursed pagans”? Did they<br> attempt to avoid conflict with revelation by saying that<br> there are two contradictory truths?</div> <div class="para">There is no doubt that the most famous master of<br> arts, Siger of Brabant, taught many of the condemned<br> doctrines. At various stages of his career, he held the<br> unity of the intellect and consequent mortality of the<br> soul, the eternity of the world, and the regularity of<br> natural change prohibiting miraculous interruption.<br> Though his attitude shifted at various times (usually<br> under the pressure of attacks from the Faculty of<br> Theology), he never admitted the possibility of two<br> contradictory truths. Nowhere in his writings does the<br> term “double truth” appear, nor do we ever find the<br> statement of two contrary truths as set down in the<br> 1277 condemnation. On the other hand, there is a good<br> deal of evidence to indicate that Siger upheld the law<br> of contradiction, thus explicitly denying the possibility<br> of a double truth. In his <span class="italics">Questions</span> on <span class="italics">Metaphysics IV,</span> <br> he says that we cannot maintain contradictory points<br> simultaneously for that is to deny what we affirm. The<br> mind itself, he holds, will not allow adherence to con-<br> tradictory propositions. Even God does not produce<br> such contradictions for He will not make man into an<br> ass. With this explicit acceptance of the law of contra-<br> diction, the problem remains of Siger's acceptance of<br> the teachings of Greco-Arabic philosophy and his si-<br> multaneous insistence on the validity of Christian<br> revelation.</div> <div class="pb"> Page 33, Volume 2</div> <div class="para"> </div> <div class="para">Siger's solution to this problem consists of three<br> different attitudes adopted at various points in his<br> teaching. The first attitude, common throughout his<br> work, is the assertion that faith is true while the doc-<br> trines of Aristotle are merely the conclusions of philos-<br> ophy and reason. The word “truth” always appears<br> associated with faith and in opposition to the teachings<br> of Aristotle and reason. Prescinding from faith, Siger<br> argues, we must investigate nature with Averroës and<br> Aristotle as our guides. Our conclusions, however, are<br> not true but simply the rational deductions of pagan<br> philosophers. In its most radical form, this attitude<br> expresses itself as the reduction of philosophical inquiry<br> to the doctrinal history of previous thinkers. When we<br> proceed philosophically, says Siger, we examine the<br> opinions of the philosophers, not the truth of the<br> matter.</div> <div class="para">But this attitude did not always satisfy him. Time<br> and again we find the assertion that the doctrines of<br> nature are not simply those of Aristotle and Averroës<br> but also the conclusions of reason. Unlike the first<br> attitude which tends to identify reason with the doc-<br> trines of Aristotelians, here reason becomes separated<br> from the philosophers; it produces a knowledge inde-<br> pendent of their teachings. At times the arguments of<br> natural reason appear “almost irrefutable.” Yet faith<br> contradicts them, and we must accept many things on<br> faith which “human reason leads us to deny.” A strict<br> antinomy develops between knowledge and faith: “I<br> know one thing; I believe another,” says Siger. There<br> is an epistemological basis for this attitude. Natural<br> philosophy, according to Siger, presents us only with<br> those laws established by human reason. Because God<br> is above rational laws, it follows that He may interrupt<br> them, not to produce absurdities but to complete the<br> inadequacies of human reason. The truth of faith is<br> not denied by contrary assertions of natural reason<br> because revelation itself derives from a source inacces-<br> sible to human reason.</div> <div class="para">Siger's insistence on the great value of autonomous<br> philosophy and the wisdom it produces leads him to<br> adopt still a third position. Impressed with the nature<br> of philosophy, Siger does not always reserve the word<br> truth for faith alone and he seems at least implicitly<br> to assert a double truth. In the <span class="italics">Commentary</span> on the<br> <span class="italics">Metaphysics,</span> he says: “The knowledge of truth belongs<br> principally to philosophy because it has for its object<br> the first causes and the first principles—thus the first<br> truths.” And in the <span class="italics">Commentary</span> on the <i>De anima,</i> he<br> holds that the knowledge of the soul gained by philos-<br> ophy is important for truth. If philosophy establishes<br> true principles and faith is still true, it seems difficult,<br> in cases of specific doctrinal conflict, to avoid the<br> statement that two contradictory truths actually exist.</div> <div class="para">The solution to this dilemma stems once more from<br> epistemological considerations. The highest truth, Siger<br> holds, can only result from the knowledge of causes<br> in themselves and not as they are inferred from effects;<br> in Siger's language we must have knowledge of causes<br> per se. Now all arguments of reason are generalizations<br> from sense perception which enable us to describe<br> nature not through its own causes but only through<br> effects registered on the mind. When set down into<br> laws, such effects can never provide final certainty<br> because they do not establish the causes per se of the<br> things they purport to describe. This reduces all philo-<br> sophical knowledge to a probable or hypothetical<br> status.</div> <div class="para">In effect Siger has established degrees of certitude.<br> Faith is absolutely certain even though it is not<br> demonstrable to reason. Rational inquiry limited, as it<br> is, to God's effects cannot attain to the causes per se<br> of these effects. For we cannot describe the mode of<br> God's activity per se which in the end is the cause<br> of the principles of nature. Rational demonstrations<br> therefore which appear final and irrefutable are such<br> only within natural limits, and consequently their<br> demonstrative status is only probable. In several places,<br> Siger endorses this probabilism: “We have demon-<br> strated above that the effect of God is eternal; this<br> conclusion is probable but not necessary”; “The argu-<br> ment of Aristotle is probable; it is not necessary”;<br> “Although the argument of the Commentator has<br> probability, it is not true” (Muller, 1938).</div> <div class="para">The second thinker mentioned in the 1277 condem-<br> nation, Boethius of Dacia, adopted essentially the same<br> attitude as Siger. The method of natural philosophy<br> must limit itself to natural causes and principles. On<br> these principles alone, we must accept the eternity of<br> the world, says Boethius. Although these principles<br> hold within the natural order, supernatural principles<br> may suspend them, not by demonstrating their falsity<br> (that is impossible) but by asserting the opposite on<br> grounds of revelation. Again we are faced with relative<br> degrees of certitude rather than the absolute validity<br> of contradictory truths. Even though Boethius praised<br> the life of philosophy in his <i>De summo bono</i> as the<br> pursuit of speculative truth and as the worthiest life<br> for man, we must bear in mind that these concepts<br> are relative to the natural order of philosophy. No-<br> where are they asserted absolutely as the 1277 con-<br> demnation claims.</div> <div class="para">There appears to be no reason to doubt the sincerity<br> of Siger and Boethius in their proclamations of loyalty<br> to the Christian religion. They were not secret atheists<br> or rationalists. Sincere Christians, they were confronted<br> with a dramatic gulf between their deeply held reli-<br> gious beliefs and the conclusions of their philosophical<br> pursuits. They adjusted the conflict by setting the<br> Christian God totally outside the natural order. Then<br> <div class="pb"> Page 34, Volume 2</div> they declared all descriptions of that order, produced<br> by philosophy, to be statements of a limited, probable,<br> and hypothetical nature. The doctrine of double truth<br> or two contradictory truths was imposed on them by<br> their adversaries who, by reading it into their state-<br> ments, hoped to end speculation they considered<br> heretical.</div> <div class="para">The 1277 condemnation effectively ended philo-<br> sophical speculation in the Faculty of Arts until the<br> end of the century. In the fourteenth century, however,<br> the masters of arts were once again allowed to take<br> up the doctrine of the Stagirite and his commentators.<br> On the testimony of two chancellors of the University,<br> Jean Gerson and John Buridan, we learn that the mas-<br> ters of the Faculty of Arts were permitted to consider<br> these doctrines provided they took an oath swearing<br> to uphold the doctrines of revelation. When expound-<br> ing pagan ideas contrary to faith, the Parisian masters<br> had to swear that they would demonstrate the falsity of<br> those views in conflict with faith. In order to do this<br> the masters asserted the necessity of giving a complete<br> exposition of pagan doctrines.</div> <div class="para">The situation can be well illustrated by considering<br> the thought of John Buridan, onetime chancellor of the<br> University, and one of the most influential scholastics<br> of the century. Like Siger, Buridan accepts the mortal-<br> ity of the soul and the eternity of the world as the<br> doctrines of philosophy. Establishing these doctrines,<br> however, requires that we understand the nature of<br> philosophical statements. All such statements are<br> merely probable because philosophical inquiry pro-<br> ceeds by three modes of understanding—experience,<br> memory, and induction—which derive from sense per-<br> ception. Since Buridan grants a realm of final truth<br> above sense perception, it is clear that empirical<br> knowledge does not arrive at ultimate certainty.</div> <div class="para">When we compare the probable philosophical theses<br> of Siger and Buridan, the major difference we discover<br> is the growth in Buridan of a natural philosophy inde-<br> pendent of Aristotle. The tendency of separating reason<br> and nature from the ideas of the philosophers—already<br> apparent in Siger—is much more marked in Buridan.<br> As a result, it is impossible for Buridan to argue that<br> he is merely reporting the opinions of previous philos-<br> ophers. From his many criticisms of Aristotle, it is quite<br> evident that he intends to establish an independent and<br> objective natural science. The assertions of philosophy<br> become the descriptions of nature, and Aristotle him-<br> self is often rejected in the name of natural reason.<br> Nevertheless, Aristotle's authority still stands so high<br> that only when Buridan agrees with the Stagirite does<br> he vigorously defend a philosophical position in sharp<br> opposition to faith.</div> <div class="para">The development of a philosophical probabilism can<br> be seen in Buridan's treatment of creation <i>ex nihilo.</i> <br> Creation out of a void, he holds, must be accepted<br> on faith but the notion that every existing being implies<br> a preexisting being is valid for philosophy. Thus, ac-<br> cording to philosophy, we must hold the eternity of<br> the world which, in turn, throws into question the<br> immortality of the soul. For if the world is eternal and<br> souls immortal, an infinite number of souls will be<br> wandering around the universe. To avoid this absurdity,<br> the logic of natural philosophy demands that we deny<br> the immortality of the soul. On the basis of natural<br> philosophy, arguments for mortality may be derived<br> either from Averroës' view of the unity of the intellect<br> or the Aristotelian Commentator Alexander of Aphro-<br> disias' (fl. 200) view of the corruptibility of individual<br> souls. Buridan chooses the Alexandrist position: the soul<br> is a form educed from the potency of matter, extended<br> to the extension of matter, multiplied in distinct bodies,<br> and finally generated and corrupted. This is the objec-<br> tively correct doctrine of natural philosophy. However,<br> Buridan decides that the doctrine of faith is true: the<br> soul inheres in matter but is eternally immortal after<br> death. For the argument of natural philosophy, he<br> concludes, is only probable and must give way before<br> the irrefutable truths of divine revelation.</div> <div class="para">The most radical Parisian master of the fourteenth<br> century, John of Jandun (d. 1328), continues the tradi-<br> tion of Siger in several ways. Jandun upholds individual<br> mortality on Averroistic grounds, explicitly rejecting<br> the “vile error” of Alexander that the soul actually<br> informs the body. The soul is not created but coeternal<br> with the world. The opposite view of faith, while not<br> demonstrable to reason, is true. God produces this by<br> a miracle not apparent to sense perception: He makes<br> the corruptible soul immortal.</div> <div class="para">In Jandun, the status of natural philosophy is also<br> raised, as in Buridan, to that of an independent, objec-<br> tive description of nature. Thus the doctrines of natural<br> reason, derived ultimately from sense perception, pro-<br> vide philosophic proofs whose demonstrative status is<br> logical not simply historical: these are not merely the<br> proofs of Averroës and Aristotle, but the independent<br> conclusions of reason. Precisely because these laws are<br> derived from rational demonstrations based on sense<br> perceptions, they are not absolutely true. They must<br> be rejected when they conflict with revelation.</div> <div class="para">Despite differences in the interpretation of the doc-<br> trine of the soul, both Buridan and Jandun subscribed<br> to Siger's original division of probable philosophical<br> demonstration vs. absolute revealed truth. A new ele-<br> ment, however, enters with Jandun. We find the first<br> written statements of those condemned propositions of<br> 1277 which spoke of Christianity as full of errors and<br> based on fables and myths. In his <span class="italics">Commentary</span> on<br> <div class="pb"> Page 35, Volume 2</div> Aristotle's <i>De anima,</i> Jandun notes that Averroës at-<br> tacks the strength of custom. It is custom alone, says<br> the Commentator, which accounts for the strength of<br> religions. Men come to accept the fables and puerile<br> notions inherent in religious belief only because they<br> have heard them from childhood. And in the Com-<br> mentary on the <i>De caelo et mundo,</i> Jandun notes that<br> Averroës refers to religion in a derogatory sense in his<br> prologue to Aristotle's <span class="italics">Physics,</span> Book III. There the<br> Commentator holds that the doctrines of religion are<br> apologies established by religious lawmakers for the<br> control of the common people; these doctrines corrupt<br> necessary principles and are “removed from truth and<br> the human mind.” The Commentator, Jandun adds, is<br> speaking of the Muslim religion, “and if he should<br> speak of our religion he would lie because all things<br> in our religion are true and proved by the miracles<br> of God and the glory of the Creator.” It is important<br> to note that Jandun may be perfectly sincere in this<br> statement. And it is equally important to say that once<br> stated, the notion that religious belief is a human in-<br> vention reinforced by conventional usage would gain<br> increasing currency.</div> <div class="para">We can begin to see this development in the late<br> fourteenth and early fifteenth centuries. Particularly<br> at the northern Italian Universities, organized without<br> faculties of theology, we find an increasing emphasis<br> not only on independent philosophical speculation but<br> also on philosophical attacks on religious truth. Most<br> thinkers continued to adhere sincerely to the earlier<br> divisions which established for the masters of arts a<br> method distinct from that of theology. But there were<br> some who denied the probable nature of philosophical<br> conclusions, asserting instead the absolute truth of<br> philosophy, and thus turning philosophical criticism<br> against Christianity itself.</div> <div class="para">Perhaps the outstanding example of this develop-<br> ment is Blasius of Parma (d. 1416). Active in Pavia,<br> Padua, and Bologna in the late fourteenth century,<br> Blasius was professor of astronomy, mathematics, and<br> philosophy. He establishes the mortality of the soul by<br> proving that the soul has no function independent of<br> bodily powers. Knowing, the highest function of the<br> soul, depends on the continuous operation of the sensi-<br> tive powers; and the eventual dissolution of the sensi-<br> tive powers carries with it the disruption and disinte-<br> gration of the mind. Since a function independent of<br> the body is the one feature Aristotle had declared as<br> proof of immortality, Blaisius claims that mortality is<br> proved. This proof has Alexandrist features and is not<br> new. But when Blasius announces that mortality is not<br> merely probable but must be accepted absolutely we<br> are in the presence of a new attitude of mind. The<br> development of this stance is worth examining.</div> <div class="para"> Like his predecessors, Blasius sharply separates<br> knowledge and belief. To know something, he declares,<br> is to have arguments based on evidence; to believe<br> something, knowledge is not necessary, and in the case<br> of faith must be set aside. Unlike earlier thinkers he<br> appears to reject the notion of asserting and denying<br> at the same time with different degrees of certitude.<br> We cannot have a probable scientific deduction in<br> conflict with an absolute religious truth. Rather we<br> must choose one or the other. “When you intend to<br> support faith which is believed,” contends Blasius, “you<br> must reject the habit of philosophy which insists on<br> evidence, and where the reverse occurs, you must<br> reject the Christian faith.”</div> <div class="para">The question of course remains: Does Blasius reject<br> Christian faith absolutely or merely as irrelevant to<br> philosophy? Perhaps he is insisting with Jandun that<br> the modes of inquiry proper to faith and reason are<br> radically different and cannot be combined; each must<br> pursue a separate path. From Blasius' discussion of the<br> soul, however, it begins to appear that he favors an<br> absolute rejection of faith. He introduces the notion<br> that the soul can be created by spontaneous generation<br> from waste, as is the case in lower forms of life. The<br> method of arriving at this conclusion is quite as inter-<br> esting as the conclusion itself. Discussing the biblical<br> story of the flood, Blasius points out that all life must<br> have been destroyed when waters covered the earth<br> for forty days. “Nor in this matter,” he warns, “should<br> you believe the tales of women that Noah made an<br> ark in which he placed all the animals” (Maier, 1949).<br> Quite the contrary, all human and animal life was<br> destroyed. Man was created anew from the waste<br> products and the appropriate constellation of the stars.<br> It is from this startling discussion that Blasius concludes<br> that the soul is mortal—produced from matter as other<br> generable and corruptible things. Now this is not a<br> probable doctrine of philosophy: Blasius contends that<br> it must be conceded absolutely.</div> <div class="para">The suspicions raised by the critique of the Bible<br> and the absolute assertion of mortality are confirmed<br> by Blasius' discussion of the origin of religions. The<br> issue is no longer the status of any particular Christian<br> belief but the value of Christianity itself. Following<br> the astrological book <i>De magnis coniunctionibus</i> of<br> Albumazar (805-85), Blasius explains that the diversity<br> of religious belief arises from the conjunction of Jupiter<br> with different planets. These in turn produce the<br> different religious sects. The Jewish sect, for example,<br> is produced from the conjunction of Jupiter with<br> Saturn, while the sect of the Saracens is caused by the<br> union of Jupiter with Venus. And “from the union of<br> Jupiter with Mercury the Christian sect is produced.”<br> Christianity here originates from the same natural<br> <div class="pb"> Page 36, Volume 2</div> forces which produce the other religions. This extreme<br> astrological determinism eliminates free choice in reli-<br> gious matters. Men no longer choose their religions<br> freely; they are naturally inclined to a particular sect<br> by the conjunction of the planets.</div> <div class="para">After some trouble with Church authorities and a<br> forced recantation, Blasius gave a later lecture in which<br> he denied these views. In this lecture he warns that<br> the views of Albumazar are erroneous and false, deny-<br> ing specifically that the conjunctions of Jupiter with<br> the other planets produce the various religions. He<br> insists furthermore that a wise man will supersede the<br> knowledge of the stars in deciding his own religious<br> belief. Despite this denial, obviously produced under<br> pressure from Church authorities, it appears that<br> Blasius accepts all these philosophical doctrines as<br> certain. He criticizes religious doctrines on philo-<br> sophical grounds, attacks biblical miracles, and reverses<br> the traditional degrees of certitude in religion and<br> philosophy. For Blasius truth appears to be on the side<br> of philosophy which claims the privilege of explaining<br> the origin of religion itself as a natural phenomenon.<br> Siger's probable philosophical statements are now<br> transformed into an absolute philosophical certitude,<br> bowing before religious belief and its representatives<br> only out of tactical necessity.</div> <div class="para">The full development of Blasius' doctrines appears<br> in the sixteenth century, which marks the final libera-<br> tion of philosophy from its subordination to revelation.<br> In the Aristotelian tradition most thinkers continued<br> to maintain sincerely the traditional distinctions be-<br> tween probable philosophical statements and absolute<br> religious truth. Some professors in the Italian<br> universities, however, developed the dramatic shift in<br> viewpoint already expressed by Blasius. Reacting<br> quickly to this, the Fifth Lateran Council of 1513<br> revived the traditional oath of the Parisian masters of<br> arts; it declared that all discussions of philosophical<br> positions opposed to faith had to include both a defense<br> of revelation and a reasoned argument against<br> heterodox notions. The theologians of the Council<br> defended orthodoxy with a proclamation of the im-<br> mortality of the soul as a dogma and the condemnation<br> of three errors: the unity of the intellect, the mortality<br> of the soul, and the idea that such doctrines were true<br> “at least in philosophy.” “Truth does not contradict<br> truth,” said the theologians, echoing the 1277 condem-<br> nation. In the works of the professors of philosophy<br> we do not find the open admission, as the Council<br> charged, of two contradictory truths. But doubtless<br> there were some who were guilty of asserting the<br> absolute truth of philosophy while paying perfunctory<br> obeisance to the “truth” of revelation. An outstanding<br> example of this attitude can be found in the works of<br> Pietro Pomponazzi (1462-1525).</div> <div class="para">Teaching natural philosophy at Padua, Ferrara, and<br> Bologna, Pomponazzi summarizes and reshapes the<br> more radical conclusions of his predecessors in the<br> Aristotelian tradition. Of the philosophical themes we<br> have traced Pomponazzi concerns himself primarily<br> with three: the mortality of the soul, the regularity<br> and universality of natural laws, and the nature of<br> religious doctrine. In his immortality treatises—<i>De<br> immortalitate animae, Apologia,</i> and <span class="italics">Defensorium</span>—he<br> proves the mortality of the soul. The proof is original<br> only in the sense that it unites many formerly disparate<br> elements. With Alexander of Aphrodisias, he insists that<br> the soul inheres in the body and is forever bound to<br> its material foundation; the corruption of the material<br> foundation entails the destruction of the soul. With<br> Blasius, he finds that no function of the soul can exist<br> without some relation to bodily powers; for even the<br> highest function of thought is part of an interlocking<br> chain of powers based on corruptible matter. With<br> Scotus, he argues against Thomas Aquinas that the soul<br> cannot simultaneously be an immaterial substance and<br> the act of the body; an immaterial substance is separate<br> and separable from the body while an act is a process<br> perfecting bodily operations. Since Aristotle had<br> always defined the soul as the act of the body, we must<br> hold that it is always bound to the powers it perfects;<br> hence it is mortal, Pomponazzi concludes.</div> <div class="para">In the <i>De incantationibus,</i> Pomponazzi discovers<br> natural causes for “miraculous occurrences.” Cures,<br> visions, and the raising of the dead are all explained<br> in three ways: as human inventions, the effects of occult<br> powers (found in plants, animals, and men), or the<br> results of the activity of the heavenly Intelligences.<br> Miracles are reduced to unusual events which only the<br> trained mind can trace to their natural causes. The<br> clear conclusion is that there are no miracles produced<br> by angels or demons because there are no interruptions<br> of the natural processes of birth, growth, and decay.</div> <div class="para">After Pomponazzi establishes these doctrines as the<br> findings of philosophy and natural reason, he applies<br> the usual distinctions which have been traditional for<br> three centuries. These are the findings of natural rea-<br> son, he says, but they must be suspended by faith. The<br> Church teaches immortality as well as miracles pro-<br> duced by God, demons, and angels. We must accept<br> all this as true, rejecting the conclusions of reason.<br> Although not demonstrable by reason, the truth of faith<br> is superior to the findings of reason. For God, who is<br> the creator of nature, may suspend its principles. In<br> these apologetic statements, Pomponazzi appears to<br> be very close to Siger, Boethius of Dacia, and Buridan.</div> <div class="pb"> Page 37, Volume 2</div> <div class="para"> </div> <div class="para">Closer examination, however, reveals that he follows<br> the path of Blasius. Like Jandun, Pomponazzi knows<br> and lectures on Averroës' prologue to <span class="italics">Physics,</span> Book<br> III. In these lectures, he proclaims in the name of the<br> Commentator that “truth is the end of philosophy<br> while the end of the religious lawgiver is neither truth<br> nor falsehood but to make men good and well-<br> behaved.” He takes the precaution, as did Jandun, of<br> associating these views with Averroës, and finally con-<br> demns them as false. But in his own name in his pub-<br> lished works there are striking instances of Pompon-<br> azzi's acceptance of philosophy as absolute truth, and<br> his discovery of a human origin for religious doctrines.<br> Immortality, he comes to state, is an invention of<br> religious lawmakers who proclaim this doctrine “not<br> caring for truth.” Clearly the truth they do not “care<br> for” is the doctrine of mortality as proved by philoso-<br> phy. Demons and angels, which he apparently has<br> accepted as the Church's teaching, he finds were also<br> invented by men “who knew very well that they did<br> not exist.”</div> <div class="para">Finally, Pomponazzi holds that Christianity is not<br> the gift of an eternal God but merely the product of<br> impersonal heavenly forces. These forces, the heavenly<br> Intelligences, produce life-cycles for all religions, in-<br> cluding Christianity. In fact, Christianity itself, he<br> explains, is approaching its death which is why the<br> Intelligences produce so few “miracles” at the present<br> time. If the origin of Christianity is temporally condi-<br> tioned, so are its doctrines. Far from eternal verities,<br> they are the inventions of religious lawmakers who seek<br> to control a bestial human nature through the fear of<br> hell and the hope of heaven. The philosopher who does<br> not need such restraints, Pomponazzi continues, may<br> nevertheless understand their purpose and approve of<br> them for the masses.</div> <div class="para">These doctrines mark the beginning of the end of<br> theological dominance in the West. Philosophy is no<br> longer a collection of probable statements but an abso-<br> lute truth subjecting all doctrines to its powerful anal-<br> ysis. It begins to dislodge theology from its position<br> as queen of the sciences.</div> <div class="para">If we glance briefly over the history we have dis-<br> cussed, we can see that the masters in the Faculty of<br> Arts at Paris initiated a tradition which lasted over<br> four centuries in the universities of Europe among<br> those philosophers who were professionally concerned<br> with Aristotle and his commentators. Refusing to find<br> or to force agreement between pagan doctrines and<br> revelation, the Parisian masters raised, in its most ex-<br> treme form, the problem of the precise relationship<br> of philosophical inquiry to revealed truth. Moreover<br> they did this at a time when revealed truth had the<br> strongest institutional sanctions. The history of the idea<br> of double truth is thus really the history of the rela-<br> tionship of philosophy to theology among professional<br> philosophers in the Aristotelian tradition. By carving<br> out an independent domain of inquiry for philosophy,<br> the earlier thinkers, led by Siger, freed philosophy from<br> the necessity of theological guidance. This made possi-<br> ble its ultimate escape from religious domination.<br> Siger, Boethius of Dacia, Jandun, and Buridan all sin-<br> cerely accepted the one supreme truth of theology.<br> Yet it was probably to be expected that some thinkers<br> in this tradition, confronted constantly with the un-<br> Christian naturalism of Aristotle, would one day pro-<br> claim the Stagirite's doctrines as the highest truth, and<br> turn this truth against theology itself.</div> <div class="para"> <span class="italics">BIBLIOGRAPHY</span> </div> <div class="para">The text of the 1277 condemnation is found in H.
