=== Epistemology === Deductive reasoning plays an important role in [[epistemology]]. Epistemology is concerned with the question of [[Justification (epistemology)|justification]], i.e. to point out which beliefs are justified and why.<ref>{{Cite encyclopedia |title=Epistemology |encyclopedia=Encyclopædia Britannica |url=https://www.britannica.com/topic/epistemology |access-date=19 March 2022}}</ref><ref>{{Cite encyclopedia |year=2020 |title=Epistemology |encyclopedia=The Stanford Encyclopedia of Philosophy |publisher=Metaphysics Research Lab, Stanford University |url=https://plato.stanford.edu/entries/epistemology/ |access-date=19 March 2022 |last2=Neta |first2=Ram |last1=Steup |first1=Matthias}}</ref> Deductive inferences are able to transfer the justification of the premises onto the conclusion.<ref name="Schechter" /> So while logic is interested in the truth-preserving nature of deduction, epistemology is interested in the justification-preserving nature of deduction. There are different theories trying to explain why deductive reasoning is justification-preserving.<ref name="Schechter" /> According to [[reliabilism]], this is the case because deductions are truth-preserving: they are reliable processes that ensure a true conclusion given the premises are true.<ref name="Schechter" /><ref>{{Cite encyclopedia |title=Reliabilism |encyclopedia=Internet Encyclopedia of Philosophy |url=https://iep.utm.edu/reliabil/ |access-date=19 March 2022 |last1=Becker |first1=Kelly}}</ref><ref>{{Cite encyclopedia |year=2021 |title=Reliabilist Epistemology |encyclopedia=The Stanford Encyclopedia of Philosophy |publisher=Metaphysics Research Lab, Stanford University |url=https://plato.stanford.edu/entries/reliabilism/ |access-date=19 March 2022 |last2=Beddor |first2=Bob |last1=Goldman |first1=Alvin}}</ref> Some theorists hold that the thinker has to have explicit awareness of the truth-preserving nature of the inference for the justification to be transferred from the premises to the conclusion. One consequence of such a view is that, for young children, this deductive transference does not take place since they lack this specific awareness.<ref name="Schechter" />
