It is likewise said, that these men expelled lamentations and tears, and every thing else of this kind. They also abstained from entreaty, from supplication, and from all such illiberal adulation, as being effeminate and abject.[46] To the same conception likewise the peculiarity of their manners must be referred, and that all of them perpetually preserved among their arcana, the most principal dogmas in which their discipline was chiefly contained, keeping them with the greatest silence from being divulged to strangers, committing them unwritten to the memory, and transmitting them orally to their successors, as if they were the mysteries of the Gods. Hence it happened, that nothing of their philosophy worth mentioning, was made public, and that though for a long time it had been taught and learnt, it was alone known within their walls. But to those out of their walls, and as I may say, to the profane, if they happened to be present, these men spoke obscurely to each other through symbols, of which the celebrated precepts that are now in circulation retain a vestige; such as, Dig not fire with a sword, and other symbols of the like kind, which, taken literally, resemble the tales of old women; but when unfolded, impart a certain admirable and venerable benefit to those that receive them. The precept, however, which is of the greatest efficacy of all others to the attainment of fortitude, is that which has for its most principal scope the being defended and liberated from those bonds which detain the intellect in captivity from infancy, and without which no one can learn or perceive any thing sane or true, through whatever sense he may energize. For according to the Pythagoreans, ’Tis mind that all things sees and hears; What else exists is deaf and blind. But the precept which is next to this in efficacy is that which exhorts to be beyond measure studious of purifying the intellect, and by various methods adapting it through mathematical orgies to receive something divinely beneficial, so as neither to fear a separation from body, nor, when led to incorporeal natures, to be forced to turn away the eyes, through their most refulgent splendor,[47] nor to be converted to those passions which nail and fasten the soul to the body. And, in short, which urges the soul to be untamed by all those passions which are the progeny of the realms of generation, and which draw it to an inferior condition of being. For the exercise and ascent through all these, is the study of the most perfect fortitude. And such are the instances adduced by us of the fortitude of Pythagoras, and the Pythagoreans. CHAP. XXXIII.
