From this brief summary we may gather that Mind was conceived, so to speak, as placed at the _beginning_ of existence, inasmuch as it is the first originator of the vortex motions of the atoms or seeds of things; it was conceived also at the _end_ of existence as the power which by analysis of the data of sensation goes back through the complexity of actual being to the original unmingled or undeveloped nature of things. But the whole process of nature itself between these limits Anaxagoras conceived as a purely mechanical or at least physical development, the uncertainty of his view as between these two alternative ways of considering it being {57} typified in his use of the two expressions _atoms_ and _seeds_. The analogies of this view with those of modern materialism, which finds in the ultimate molecules of matter "the promise and the potency of all life and all existence," need not be here enlarged upon. After nearly half a century's teaching at Athens Anaxagoras was indicted on a charge of inculcating doctrines subversive of religion. It is obvious enough that his theories left no room for the popular mythology, but the Athenians were not usually very sensitive as to the bearing of mere theories upon their public institutions. It seems probable that the accusation was merely a cloak for political hostility. Anaxagoras was the friend and intimate of Pericles, leader of the democratic party in the state, and the attack upon Anaxagoras was really a political move intended to damage Pericles. As such Pericles himself accepted it, and the trial became a contest of strength, which resulted in a partial success and a partial defeat for both sides. Pericles succeeded in saving his friend's life, but the opposite party obtained a sentence of fine and banishment against him. Anaxagoras retired to Lampsacus, a city on the Hellespont, and there, after some five years, he died. {58} CHAPTER VII THE ATOMISTS (_continued_) _Empedocles at Etna--Brief life and scanty vision--The four elements--The philosophy of contradiction--Philosophy a form of poesy--The philosopher a prophet--Sensation through kinship--The whole creation groaneth_ [129]
