to experience and observation. This leading up of the particular to the universal is the finding out of laws, natural forces, and so on. It may thus be said that Epicurus is the inventor of empiric Natural Science, of empiric Psychology. In contrast to the Stoic ends, conceptions of the understanding, experience is the present as it appears to the senses: there we have abstract limited understanding, without truth in itself, and therefore without the present in time and the reality of Nature; here we have this sense of Nature, which is more true than these other hypotheses. The same effect which followed the rise of a knowledge of natural laws, &c., in the modern world was produced by the Epicurean philosophy in its own sphere, that is to say, in so far as it is directed against the arbitrary invention of causes. The more, in later times, men made acquaintance with the laws of Nature, the more superstition, miracles, astrology, &c. disappeared; all this fades away owing to the contradiction offered to it by the knowledge of natural laws. The method of Epicurus was directed more especially against the senseless superstition of astrology, &c., in whose methods there is neither reason nor thought, for it is quite a thing of the imagination, downright fabrication being resorted to, or what we may even term lying. In contrast with this, the way in which Epicurus works, when the conceptions and not thought are concerned, accords with truth. For it does not go beyond what is perceived by the sight, and hearing, and the other senses, but keeps to what is present and not alien to the mind, not speaking of certain things as if they could be seen and heard, when that is quite impossible, seeing that the things are pure inventions. The effect of the Epicurean philosophy in its own time was therefore this, that it set itself against the superstition of the Greeks and Romans, and elevated men above it.[160] All the nonsense about birds flying to right or to left, or a hare running across the path, or men deciding how they are to act according to the entrails of animals, or according as chickens are lively or dull—all that kind of superstition the Epicurean philosophy made short work of, by permitting that only to be accepted as truth which is counted as true by sense perception through the instrumentality of anticipations; and from it more than anything those conceptions which have altogether denied the supersensuous have proceeded. The physics of Epicurus were therefore famous for the reason that they introduced more enlightened views in regard to what is physical, and banished the fear of the gods. Superstition passes straightway from immediate appearances to God, angels, demons; or it expects from finite things other effects than the conditions admit of, phenomena of a higher kind. To this the Epicurean natural philosophy is utterly opposed, because in the sphere of the finite it refuses to go beyond the finite, and admits finite causes
