These inferences from the observed to the unobserved are known as "inductive inferences". <a href="/wiki/David_Hume" title="David Hume">David Hume</a>, who first formulated the problem in 1739,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> argued that there is no non-circular way to justify inductive inferences, while he acknowledged that everyone does and must make such inferences.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p><p>The traditional <a href="/wiki/Inductivism" title="Inductivism">inductivist</a> view is that all claimed <a href="/wiki/Empirical_evidence" title="Empirical evidence">empirical</a> laws, either in everyday life or through the <a href="/wiki/Scientific_method" title="Scientific method">scientific method</a>, can be justified through some form of reasoning. The problem is that many philosophers tried to find such a justification but their proposals were not accepted by others. Identifying the inductivist view as the scientific view, <a href="/wiki/C._D._Broad" title="C. D. Broad">C. D. Broad</a> once said that induction is "the glory of science and the scandal of philosophy".<sup id="cite_ref-FOOTNOTEGustavsson2021&#91;httpsplatostanfordeduarchivesfall2021entriesbroadnoteshtmlnote-16_Note_16&#93;_in_Sec._7_3-0" class="reference"><a href="#cite_note-FOOTNOTEGustavsson2021[httpsplatostanfordeduarchivesfall2021entriesbroadnoteshtmlnote-16_Note_16]_in_Sec._7-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> In contrast, <a href="/wiki/Karl_Popper" title="Karl Popper">Karl Popper</a>'s <a href="/wiki/Critical_rationalism" title="Critical rationalism">critical rationalism</a> claimed that inductive justifications are never used in science and proposed instead that science is based on the procedure of conjecturing <a href="/wiki/Hypotheses" class="mw-redirect" title="Hypotheses">hypotheses</a>, <a href="/wiki/Deductive" class="mw-redirect" title="Deductive">deductively</a> calculating consequences, and then empirically attempting to <a href="/wiki/Falsify" class="mw-redirect" title="Falsify">falsify</a> them. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Formulation_of_the_problem">Formulation of the problem</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Problem_of_induction&amp;action=edit&amp;section=1" title="Edit section: Formulation of the problem"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In <a href="/wiki/Inductive_reasoning" title="Inductive reasoning">inductive reasoning</a>, one makes a series of observations and <a href="/wiki/Inference" title="Inference">infers</a> a claim based on them. For instance, from a series of observations that a woman walks her dog by the market at 8 am on Monday, it seems valid to infer that next Monday she will do the same, or that, in general, the woman walks her dog by the market every Monday. That next Monday the woman walks by the market merely adds to the series of observations, but it does not prove she will walk by the market every Monday. First of all, it is not certain, regardless of the number of observations, that the woman always walks by the market at 8 am on Monday.

His formulation of the problem of induction can be found in <i><a href="/wiki/An_Enquiry_concerning_Human_Understanding" class="mw-redirect" title="An Enquiry concerning Human Understanding">An Enquiry concerning Human Understanding</a></i>, §4. Here, Hume introduces his famous distinction between "relations of ideas" and "matters of fact". Relations of ideas are propositions which can be derived from deductive logic, which can be found in fields such as geometry and algebra. Matters of fact, meanwhile, are not verified through the workings of deductive logic but by experience. Specifically, matters of fact are established by making an inference about causes and effects from repeatedly observed experience. While relations of ideas are supported by reason alone, matters of fact must rely on the connection of a cause and effect through experience. Causes of effects cannot be linked through a priori reasoning, but by positing a "necessary connection" that depends on the "uniformity of nature". </p><p>Hume situates his introduction to the problem of induction in <i><a href="/wiki/A_Treatise_of_Human_Nature" title="A Treatise of Human Nature">A Treatise of Human Nature</a></i> within his larger discussion on the nature of causes and effects (Book I, Part III, Section VI). He writes that reasoning alone cannot establish the grounds of causation. Instead, the human mind imputes causation to phenomena after repeatedly observing a connection between two objects. For Hume, establishing the link between causes and effects relies not on reasoning alone, but the observation of "<i>constant conjunction</i>" throughout one's sensory experience. From this discussion, Hume goes on to present his formulation of the problem of induction in <i>A Treatise of Human Nature</i>, writing "there can be no <i>demonstrative</i> arguments to prove, <i>that those instances, of which we have had no experience, resemble those, of which we have had experience</i>." </p><p>In other words, the problem of induction can be framed in the following way: we cannot apply a conclusion about a particular set of observations to a more general set of observations. While deductive logic allows one to arrive at a conclusion with certainty, inductive logic can only provide a conclusion that is probably true.<sup class="noprint Inline-Template noprint Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:No_original_research#Primary,_secondary_and_tertiary_sources" title="Wikipedia:No original research"><span title="This claim needs references to reliable secondary sources. (November 2020)">non-primary source needed</span></a></i>&#93;</sup> It is mistaken to frame the difference between deductive and inductive logic as one between general to specific reasoning and specific to general reasoning. This is a common misperception about the difference between inductive and deductive thinking. According to the literal standards of logic, deductive reasoning arrives at certain conclusions while inductive reasoning arrives at probable conclusions. <sup class="noprint Inline-Template noprint Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:No_original_research#Primary,_secondary_and_tertiary_sources" title="Wikipedia:No original research"><span title="This claim needs references to reliable secondary sources. (November 2020)">non-primary source needed</span></a></i>&#93;</sup> Hume's treatment of induction helps to establish the grounds for probability, as he writes in <i>A Treatise of Human Nature</i> that "probability is founded on the presumption of a resemblance betwixt those objects, of which we have had experience, and those, of which we have had none" (Book I, Part III, Section VI).<sup class="noprint Inline-Template noprint Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:No_original_research#Primary,_secondary_and_tertiary_sources" title="Wikipedia:No original research"><span title="This claim needs references to reliable secondary sources. (November 2020)">non-primary source needed</span></a></i>&#93;</sup> </p><p>Therefore, Hume establishes induction as the very grounds for attributing causation. There might be many effects which stem from a single cause. Over repeated observation, one establishes that a certain set of effects are linked to a certain set of causes. However, the future resemblance of these connections to connections observed in the past depends on induction. Induction allows one to conclude that "Effect A2" was caused by "Cause A2" because a connection between "Effect A1" and "Cause A1" was observed repeatedly in the past. Given that reason alone can not be sufficient to establish the grounds of induction, Hume implies that induction must be accomplished through imagination. One does not make an inductive reference through a priori reasoning, but through an imaginative step automatically taken by the mind. </p><p>Hume does not challenge that induction is performed by the human mind automatically, but rather hopes to show more clearly how much human inference depends on inductive—not <a href="/wiki/A_priori" class="mw-redirect" title="A priori">a priori</a>—reasoning. He does not deny future uses of induction, but shows that it is distinct from deductive reasoning, helps to ground causation, and wants to inquire more deeply into its validity. Hume offers no solution to the problem of induction himself. He prompts other thinkers and logicians to argue for the validity of induction as an ongoing dilemma for philosophy. A key issue with establishing the validity of induction is that one is tempted to use an inductive inference as a form of justification itself. This is because people commonly justify the validity of induction by pointing to the many instances in the past when induction proved to be accurate. For example, one might argue that it is valid to use inductive inference in the future because this type of reasoning has yielded accurate results in the past. However, this argument relies on an inductive premise itself—that past observations of induction being valid will mean that future observations of induction will also be valid. Thus, many solutions to the problem of induction tend to be circular. </p> <div class="mw-heading mw-heading3"><h3 id="Nelson_Goodman's_new_riddle_of_induction"><span id="Nelson_Goodman.27s_new_riddle_of_induction"></span>Nelson Goodman's new riddle of induction</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Problem_of_induction&amp;action=edit&amp;section=7" title="Edit section: Nelson Goodman&#039;s new riddle of induction"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/New_riddle_of_induction" title="New riddle of induction">New riddle of induction</a></div> <p><a href="/wiki/Nelson_Goodman" title="Nelson Goodman">Nelson Goodman</a>'s <i><a href="/wiki/Fact,_Fiction,_and_Forecast" title="Fact, Fiction, and Forecast">Fact, Fiction, and Forecast</a></i> (1955) presented a different description of the problem of induction in the chapter entitled "The New Riddle of Induction". Goodman proposed the new <a href="/wiki/Predicate_(mathematical_logic)" title="Predicate (mathematical logic)">predicate</a> "<a href="/wiki/Grue_and_Bleen" class="mw-redirect" title="Grue and Bleen">grue</a>". Something is grue if and only if it has been (or will be, according to a scientific, general hypothesis<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">&#91;</span>14<span class="cite-bracket">&#93;</span></a></sup><sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">&#91;</span>15<span class="cite-bracket">&#93;</span></a></sup>) observed to be green before a certain time <i>t</i>, and blue if observed after that time. The "new" problem of induction is, since all emeralds we have ever seen are both green and grue, why do we suppose that after time <i>t</i> we will find green but not grue emeralds? The problem here raised is that two different inductions will be true and false under the same conditions. In other words: </p> <ul><li>Given the observations of a lot of green emeralds, someone using a common language will inductively infer that all emeralds are green (therefore, he will believe that any emerald he will ever find will be green, even after time <i>t</i>).</li> <li>Given the same set of observations of green emeralds, someone using the predicate "grue" will inductively infer that all emeralds, which will be observed after <i>t</i>, will be blue, despite the fact that he observed only green emeralds so far.</li></ul> <p>One could argue, using <a href="/wiki/Occam%27s_razor" title="Occam&#39;s razor">Occam's razor</a>, that greenness is more likely than grueness because the concept of grueness is more complex than that of greenness. Goodman, however, points out that the predicate "grue" only appears more complex than the predicate "green" because we have defined grue in terms of blue and green. If we had always been brought up to think in terms of "grue" and "bleen" (where bleen is blue before time <i>t</i>, and green thereafter), we would intuitively consider "green" to be a crazy and complicated predicate. Goodman believed that which scientific hypotheses we favour depend on which predicates are "entrenched" in our language.<sup class="noprint Inline-Template" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:No_original_research" title="Wikipedia:No original research"><span title="The material near this tag possibly contains original research.

For example, the majority of the subsets which contain 3000 ravens which you can form from the raven population are similar to the population itself (and this applies no matter how large the raven population is, as long as it is not infinite). Consequently, Stove argued that if you find yourself with such a subset then the chances are that this subset is one of the ones that are similar to the population, and so you are justified in concluding that it is likely that this subset "matches" the population reasonably closely. The situation would be analogous to drawing a ball out of a barrel of balls, 99% of which are red. In such a case you have a 99% chance of drawing a red ball. Similarly, when getting a sample of ravens the probability is very high that the sample is one of the matching or "representative" ones. So as long as you have no reason to think that your sample is an unrepresentative one, you are justified in thinking that probably (although not certainly) that it is.<sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span class="cite-bracket">&#91;</span>23<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Biting_the_bullet:_Keith_Campbell_and_Claudio_Costa">Biting the bullet: Keith Campbell and Claudio Costa</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Problem_of_induction&amp;action=edit&amp;section=12" title="Edit section: Biting the bullet: Keith Campbell and Claudio Costa"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>An intuitive answer to Hume would be to say that a world inaccessible to any inductive procedure would simply not be conceivable.

The rational motivation for choosing a well-corroborated theory is that it is simply easier to falsify: Well-corroborated means that at least one kind of experiment (already conducted at least once) could have falsified (but did not actually falsify) the one theory, while the same kind of experiment, regardless of its outcome, could not have falsified the other. So it is rational to choose the well-corroborated theory: It may not be more likely to be true, but if it is actually false, it is easier to get rid of when confronted with the conflicting evidence that will eventually turn up.
