146 XLI. As, therefore, a musical ear detects even the slightest falsity of tone in a harp, so we, if we wish to be keen and careful observers of moral faults, shall often draw important conclusions from trifles. We observe others and from a glance of the eyes, from a contracting or relaxing of the brows, from an air of sadness, from an outburst of joy, from a laugh, from speech, from silence, from a raising or lowering of the voice, and the like, we shall easily judge which of our actions is proper, and which is out of accord with duty and nature. And, in the same manner, it is not a bad plan to judge of the nature of our every action by studying others, that so we may ourselves avoid anything that is unbecoming in them. For it happens somehow or other that we detect another's failings more readily than we do our own; and so in the school-room those pupils learn most easily to do better whose faults the masters mimic for the sake of correcting them.
(2) by the criticisms of the wise.
147 Nor is it out of place in making a choice between duties involving a doubt, to consult men of learning or practical wisdom and to ascertain what their views are on any particular question of duty. For the majority usually drift as the current of their own natural inclinations carries them; and in deriving counsel from one of these, we have to see not only what our adviser says, but also what he thinks, and what his reasons are for thinking as he does. For, as painters and sculptors and even poets, too, wish to have their works reviewed by the public, in order that, if any point is generally criticized, it may be improved; and as they try to discover both by themselves and with the help of others what is wrong in their work; so through consulting the judgment of others we find that there are many things to be done and left undone, to be altered and improved.
The laws of the state are rules of duty.
148 But no rules need to be given about what is done in accordance with the established customs and conventions of a community; for these are in themselves rules; and no one ought to make the mistake of supposing that, because Socrates or Aristippus did or said something contrary to the manners and established customs of their city, he has a right to do the same; it was only by reason of their great and superhuman virtues that those famous men acquired this special privilege. But the Cynics' whole system of philosophy must be rejected, for it is inimical to moral sensibility, and without moral sensibility nothing can be upright, nothing morally good.
Special rules.
149 It is, furthermore, our duty to honour and reverence those whose lives are conspicuous for conduct in keeping with their high moral standards, and who, as true patriots, have rendered or are now rendering efficient service to their country, just as much as if they were invested with some civil or military authority; it is our duty also to show proper respect to old age, to yield precedence to magistrates, to make a distinction between a fellow-citizen and a foreigner, and, in the case of the foreigner himself, to discriminate according to whether he has come in an official or a private capacity. In a word, not to go into details, it is our duty to respect, defend, and maintain the common bonds of union and fellowship subsisting between all the members of the human race.
150 XLII. Iam de artificiis et quaestibus, qui liberales habendi, qui sordidi sint, haec fere accepimus. Primum improbantur ii quaestus, qui in odia hominum incurrunt, ut portitorum, ut faeneratorum. Illiberales autem et sordidi quaestus mercennariorum omnium, quorum operae, non quorum artes emuntur; est enim in illis ipsa merces auctoramentum servitutis. Sordidi etiam putandi, qui mercantur a mercatoribus, quod statim vendant; nihil enim proficiant, nisi admodum mentiantur; nec vero est quicquam turpius vanitate. Opificesque omnes in sordida arte versantur; nec enim quicquam ingenuum habere potest officina. Minimeque artes eae probandae, quae ministrae sunt voluptatum:
