(2) “It is reported that you philosophize to every one you may happen to meet, and publicly, which Pythagoras did not think fit to do. And these things, indeed, O Hipparchus, you learnt with diligent assiduity, but you have not preserved them; having tasted, O excellent man, of Sicilian delicacies, which you ought not to have tasted a second time. If, therefore, you abandon these, I shall rejoice; but if not, you will be dead in my opinion. For it will be pious to call to mind the divine and human precepts of Pythagoras, and not to make the goods of wisdom common to those, who have not even in a dream their soul purified. For it is not lawful to extend to every casual person, things which were obtained with such great labors, and such diligent assiduity, nor to divulge the mysteries of the Eleusinian Goddesses to the profane.

For those who do either of these, are equally unjust and impious. But it will be well to consider what a great length of time we consumed in wiping away the stains which had insinuated themselves into our breasts, till, after the lapse of some years, we became fit recipients of the doctrines of Pythagoras. For as dyers previously purify garments, and then fix in the colors with which they wish them to be imbued, in order that the dye may not be washed away, and may never become evanescent; after the same manner also that divine man prepared the souls of those that were lovers of philosophy, so that they might not deceive him in any of those beautiful and good qualities which he hoped they would possess.

For he did not impart spurious doctrines, nor snares, in which most of the sophists, who are at leisure for no good purpose, entangle young men; but he possessed a scientific knowledge of things human and divine. These men, however, making his doctrine a pretext, perform many dreadful deeds, ensnaring youth not in a becoming nor yet in a casual way. Hence they render their auditors noxious and precipitate. For they infuse theorems and divine doctrines into confused and turbid manners. Just as if some one should pour pure and clear water into a deep well full of mud; for he would disturb the mud, and destroy the clear water. The same thing likewise takes place between those who teach and those who are taught after this manner.

For dense thickets and which are full of briars surround the intellect and heart of those who have not been purely initiated in disciplines, obscure the mild, tranquil, and reasoning power of the soul, and openly impede the intellective part from becoming increased and elevated. It is requisite likewise to call intemperance and avarice the mothers of these thickets; both which are naturally prolific. From intemperance, therefore, unlawful marriages, [unjust] desires, corruptions, intoxication, preternatural pleasures, and certain vehement appetites blossom forth, and which impel their possessors into profundities and precipices. For now desires have compelled some not to abstain either from their mothers or their daughters, and violating law, their country, city, and king, with their hands as it were bound behind them, they are violently dragged along like slaves to extreme destruction.

But from avarice germinate rapine, robbery, parricide, sacrilege, sorcery, and such other evils at are the sisters of these. In the first place, therefore, it is necessary to purify the woods in which these passions have fixed their abode, with fire and sword, and all the machines of disciplines; and having liberated the reasoning power from such mighty evils, we may then implant in and deliver to it something useful and good.” So great and so necessary was the attention which, according to Pythagoras, ought to be paid to disciplines prior to philosophy. He likewise ordained that a singular honor, and the most accurate investigation, should be given to the teaching and participation of his dogmas, as he judiciously examined the conceptions of those that came to him, by various documents, and ten thousand forms of scientific theory.

(15) And exhibiting the Christian life, he writes in the Theoetetus in these words: "Let us now speak of the highest principles. For why should we speak of those who make an abuse of philosophy? These know neither the way to the forum, nor know they the court or the senate-house, or any other public assembly of the state. As for laws and decrees spoken or written, they neither see nor hear them. But party feelings of political associations and public meetings, and revels with musicians [occupy them]; but they never even dream of taking part in affairs. Has any one conducted himself either well or ill in the state, or has aught evil descended to a man from his forefathers? - it escapes their attention as much as do the sands of the sea.

(11) Wherefore those who are determined to live piously ought none the less to exhibit alacrity, when some seem to exercise compulsion on them; but much more, I think, does it become them to show eagerness, and to strive with uncommon vigour, lest, being overcome, they abandon the best and most indispensable counsels. For it does not, I think, admit of comparison, whether it be better to be a follower of the Almighty than to choose the darkness of demons. For the things which are done by us on account of others we are to do always, endeavouring to have respect to those for whose sake it is proper that they be done, regarding the gratification rendered in their case, as what is to be our rule; but the things which are done for our own sake rather than that of others, are to be done with equal earnestness, whether they are like to please certain people or not. If some indifferent things have obtained such honour as to appear worthy of adoption, though against the will of some; much more is virtue to be regarded by us as worth contending for, looking the while to nothing but what can be rightly done, whether it seem good to others or not. Well then, Epicurus, writing to Menoeceus, says, "Let not him who is young delay philosophizing, and let not the old man grow weary of philosophizing; for no one is either not of age or past age for attending to the health of his soul. And he who says that the time for philosophizing is not come or is past, is like the man who says that the time for happiness is not come or has gone. So that young s as well as old ought to philosophize: the one, in order that, while growing old, he may grow young in good things out of favour accruing from what is past; and the other, that he may be at once young and old, from want of fear for the future."

(19) Socrates: and still harder in speech. Again, as to the class of Sophists, although I esteem them highly versed in many fine discourses of other kinds, yet I fear lest haply, seeing they are a class which roams from city to city and has no settled habitations of its own, they may go wide of the mark in regard to men who are at once philosophers and statesmen, and what they would be likely to do and say, in their several dealings with foemen in war and battle, both by word and deed. Thus there remains only that class which is of your complexion—
