Abstract
In the Introduction to A Treatise of Human Nature, Hume says he will make a careful empirical study of the human mind and produce a “science of man.” This will provide us with knowledge of the principles of human nature, and these principles will explain “our reasoning faculty, and the nature of our ideas,” “our tastes and sentiments,” and the union of “men … in society”. This seems to be a wholly constructive philosophical ambition, and yet Hume also claims to discover “manifold contradictions and imperfections in human reason,” and he confesses that an “intense view” of these discoveries “has so wrought upon me, and heated my brain, that I am ready to reject all belief and reasoning, and can look upon no opinion even as more probable or likely than another”. It is hard to imagine a more deeply negative outlook than this, or one more at odds with the outlook of the scientist of man.
