Deductive Reasoning - Hume's Skepticism

Hume's Skepticism

See also: Problem of induction

Philosopher David Hume presented grounds to doubt deduction by questioning induction. Hume's problem of induction starts by suggesting that the use of even the simplest forms of induction simply cannot be justified by inductive reasoning itself. Moreover, induction cannot be justified by deduction either. Therefore, induction cannot be justified rationally. Consequently, if induction is not yet justified, then deduction seems to be left to rationally justify itself – an objectionable conclusion to Hume.

Famous quotes containing the words hume and/or skepticism:

    There is not to be found, in all history, any miracle attested by a sufficient number of men, of such unquestioned good sense, education, and learning, as to secure us against all delusion in themselves ... beyond all suspicion of any design to deceive others ... and at the same time attesting facts, performed in such a public manner, and in so celebrated a part of the world, as to render the detection unavoidable.
    —David Hume (1711–1776)

    A major problem for Black women, and all people of color, when we are challenged to oppose anti-Semitism, is our profound skepticism that white people can actually be oppressed.
    Barbara Smith (b. 1946)
