(7) With respect also to opinion, it is related that they spoke of it as follows: That it is the province of a stupid man to pay attention to the opinion of every one, and especially to that of the multitude. Far it belongs to a few only to apprehend and opine rightly; since it is evident that this pertains to the intelligent alone. But they are few. It is manifest therefore, that a power of this kind does not extend itself to the multitude. But it is also stupid to despise the opinion of every one. For it will happen that he who is so disposed will be unlearned and incorrigible. It is however necessary that he who is destitute of science should learn those things of which he is ignorant, and has no scientific knowledge.

And it is likewise necessary that the learner should pay attention to the opinion of him who possesses science, and is able to teach. And universally, it is necessary that those young men who wish to be saved, should attend to the opinion of their elders, and of those who have lived well. But in the whole of human life there are certain ages (denominated by them as it is said endedasmenæ ) which it is not in the power of any casual person to connect with each other. For they are expelled by each other, unless some one conducts a man from his birth, in a beautiful and upright manner. It is necessary therefore, when a child is educated well, and is formed to temperance and fortitude, that a great part of his education should be given to the age of adolescence [which is that of a lad].

In a similar manner also, when a lad is formed to temperance and fortitude, it is necessary that a great part of his education should be transferred to the age of manhood. For that which happens to the multitude is absurd and ridiculous. For they fancy it is requisite that boys should be orderly and temperate, and should abstain from every thing which appears to be troublesome and indecorous; but that when they have arrived at adolescency, they may for the most part do whatever they please. Hence there is nearly a conflux of both kinds of errors into this age. For lads commit many faults which are both puerile and virile. For, in short, to avoid every kind of sedulity and order, and to pursue every species of sport, and puerile intemperance and insolence, are most adapted to the age of a boy.

Such a disposition therefore as this, is derived from the puerile into the following age. But the genus of strong desires, and of different species of ambition, and in a similar manner the remaining impulses and dispositions, when they are of a severe and turbulent nature, are derived from the virile age into that of adolescency. Hence this of all the ages demands the greatest attention. And universally, no man ought to be suffered to do whatever he pleases, but it is always necessary that there should be a certain inspection, and a legal and elegantly-formed government, to which each of the citizens is obedient. For the animal, when left to itself and neglected, rapidly degenerates into vice and depravity.

(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.

(7) The Ionic muses accordingly expressly say, "That the majority of people, wise in their own estimation, follow minstrels and make use of laws, knowing that many are bad, few good; but that the best pursue glory: for the best make choice of the everlasting glory of men above all. But the multitude cram themselves like brutes, measuring happiness by the belly and the pudenda, and the basest things in us." And the great Parmenides of Elea is introduced describing thus the teaching of the two ways: "The one is the dauntless heart of convincing truth; The other is in the opinions of men, in whom is no true faith."
