Thus, according to this doctrine, Man, considered as a relative unity contained in the absolute Unity of the Grand All, presents himself as the universal ternary, under three principal modifications, of body, soul, and spirit or intelligence. The soul, considered as the seat of the passions, is presented in its turn, under the three faculties of the rational, irascible or appetent soul. Now, in the opinion of Pythagoras, the vice of the appetent faculty of the soul is intemperance or avarice; that of the irascible faculty is cowardice; and that of the rational faculty is folly. The vice which reaches these three faculties is injustice. In order to avoid these vices, the philosopher commends four principal virtues to his disciples: temperance for the appetent faculty, courage for the irascible faculty, prudence for the rational faculty, and for these three faculties together, justice, which he regards as the most perfect virtue of the soul.[362] I say the soul, because the body and the intelligence, being equally developed by means of three faculties instinctive or spiritual, as well as the soul, were susceptible of the vices and the virtues which were peculiar to them. 9. _Speak not nor act before thou hast reflected; Be just._ By the preceding lines, Lysis, speaking in the name of Pythagoras, had commended temperance and diligence; he had prescribed particularly watching over the irascible faculty, and moderating its excesses; by these, he indicates the peculiar character of prudence which is reflection and he imposes the obligation of being just, by binding, as it were, the most energetic idea of justice with that of death, as may be seen in the subsequent lines: 10. … _Remember that a power invincible Ordains to die_; … That is to say, remember thou that the fatal necessity to which thou art subjected in reference to the material and mortal part of thyself, according to the sentence of the ancient sages,[363] will strike thee particularly in the objects of thy cupidity, of thy intemperance, in the things which will have excited thy folly, or flattered thy cowardice; remember thou that death will break the frail instruments of thy wrath, will extinguish the firebrands that it will have lighted; remember thou finally, 11. … _That riches and the honours Easily acquired, are easy thus to lose._ Be just: injustice has often easy triumphs; but what remains after death of the riches that it has procured? Nothing but the bitter remembrance of their loss, and the nakedness of a shameful vice uncovered and reduced to impotency.
