ABSTRACT
David Hume (1711-76) is one of the most important among philosophers, because he developed to its logical conclusion the empirical philosophy of Locke and Berkeley, and by making it self-consistent made it incredible. He represents, in a certain sense, a dead end: in his direction, it is impossible to go further. He begins with the distinction between 'impressions' and 'ideas'. These are two kinds of perceptions, of which impressions are those that have more force and violence. The psychological objection is more serious, at least in connection with Hume. The whole theory of ideas as copies of impressions, as he sets it forth, suffers from ignoring vagueness. The psychological objection is more serious, at least in connection with Hume.
