David Hume

Opis

Hume's introduction presents the idea of placing all science and philosophy on a novel foundation: namely, an empirical investigation into human psychology. He begins by acknowledging "that common prejudice against metaphysical reasonings i.e., any complicated and difficult argumentation]," a prejudice formed in reaction to "the present imperfect condition of the sciences" (including the endless scholarly disputes and the inordinate influence of "eloquence" over reason). But since the truth "must lie very deep and abstruse" where "the greatest geniuses" have not found it, careful reasoning is still needed. All sciences, Hume continues, ultimately depend on "the science of man": knowledge of "the extent and force of human understanding, ... the nature of the ideas we employ, and... the operations we perform in our reasonings" is needed to make real intellectual progress. So Hume hopes "to explain the principles of human nature," thereby "propos ing] a compleat system of the sciences, built on a foundation almost entirely new, and the only one upon which they can stand with any security." But an a priori psychology would be hopeless: the science of man must be pursued by the experimental methods of the natural sciences. This means we must rest content with well-confirmed empirical generalizations, forever ignorant of "the ultimate original qualities of human nature." And in the absence of controlled experiments, we are left to "glean up our experiments in this science from a cautious observation of human life, and take them as they appear in the common course of the world, by men's behaviour in company, in affairs, and in their pleasures.
