"All was oracular and dogmatic in the school of Pythagoras. He prized and justly prized the greatness of his attainments and discoveries, and had no conception that any thing could go beyond them. He did not encourage, nay, he resolutely opposed, all true independence of mind, and that undaunted spirit of enterprise which is the atmosphere in which the sublimest thoughts are most naturally generated. He therefore did not throw open the gates of science and wisdom, and invite every comer; but on the contrary narrowed the entrance, and carefully reduced the number of aspirants. He thought not of the most likely methods to give strength and permanence and an extensive sphere to the progress of the human mind. For these reasons he wrote nothing; but consigned all to the frail and uncertain custody of tradition. And distant posterity has amply avenged itself upon the narrowness of his policy; and the name of Pythagoras, which would otherwise have been ranked with the first luminaries of mankind, and consigned to everlasting gratitude, has in consequence of a few radical and fatal mistakes, been often loaded with obloquy, and the hero who bore it been indiscriminately classed among the votaries of imposture and artifice."
