same name with one another:--"He takes the word _vacuum_ in a sense in which no one has ever understood it, building castles in the air, and then pulling down his 'vacuum,' but not that of any other who has spoken of a vacuum or made use of the name. So he acts in all other cases,--those for example of 'motion,' 'infinite,' 'matter,' 'form,' 'demonstration,' 'being,' always building on the faith of his own definition, which gives the name a new sense."[168] [Sidenote: The Pre-Aristotelians.] The close study of Aristotle himself, which was one of the greatest results of the Humanist movement, had the effect of bringing into greater prominence the earlier Greek philosophers, whose doctrines Aristotle states and criticises in many of his works--notably the _Physics_ and _Metaphysics_. The rediscovery of antiquity included that of ancient philosophy; and Bruno's dissatisfaction with Aristotle led him into greater sympathy with the nature-philosophers whom Aristotle decried. Towards these earlier Greeks, as towards other philosophers, his attitude is wholly that of an Eclectic: he does not attempt to appreciate their relative value, nor to discover any evolution of thought through the successive systems. From each he takes that which agrees or appears to agree with his own philosophy, and treats it as an anticipation of, or as an authority for, the latter. The "universal intelligence," for example, as the universal efficient cause in nature, is a doctrine ascribed in the _Causa_ indiscriminately to the Pythagoreans, the Platonists, the Magi, Orpheus, Empedocles, and Plotinus.[169] The belief in an infinite ether (Heraclitus' Fire) surrounding the earth, and containing innumerable worlds within it, in the _Cena_ is attributed, equally without discrimination, to Heraclitus, Democritus, Epicurus, Pythagoras, Parmenides, and Melissus.[170] Xenophanes represented for Bruno the static aspect of Pantheism--the Absolute One as in itself, apart from all reference to the finite;[171] Heraclitus its dynamic aspect--the Absolute as unfolding, revealing itself, "appearing" in and through the finite.[172] Anaxagoras expressed the relation between the finite individual and the One,--"All things are in all things," for "omnipotent, all-producing divinity pervades the whole, therefore nothing is so small but that divinity lies concealed in it."[173] "Everything is in everything, because spirit or soul is in all things, and therefore out of anything may be produced anything else."[174] To Anaxagoras, as to Bruno, nature was divine.[175] No special distinction was made by Bruno between the teaching of Anaxagoras and that of Empedocles: in one passage he attributes to the former the theory of effluxes and influxes of atoms through the pores of bodies, which really belongs to the latter,[176] and in another suggests that Empedocles only put in a more "abstract" way what Anaxagoras had shown "concretely," that all things are in all.[177] [Sidenote: Democritus]
