In the absence of any possibility of intellectual certainty, Marcus fell back upon conduct. Here his want of originality and of spiritual force was less felt, for conduct has tolerably well-established rules of neighbourliness, purity, good temper, public duty and the like. His Stoic guides, too, might in this region help him to follow with more confidence the voice of his own pure and delicate conscience--the conscience of a saint and a quietist rather than that of a man of action. Yet even in the realm of conduct he is on the whole ineffectual. Pure, truthful, kind, and brave he is, but he does not believe enough to be great. He is called to be a statesman and an administrator; he does not expect much outcome from all his energies, and he preaches to himself the necessity of patience with his prospective failure to achieve anything beyond the infinitesimal. "Ever the same are the cycles of the universe, up and down, for ever and for ever. Either the intelligence of the Whole puts itself in motion for each separate effect--in which case accept the result it gives; or else it did so once for all, and everything is sequence, one thing in another ... [The text is doubtful for a line] ... In a word, either God, and all goes well; or all at random--live not thou at random. "A moment, and earth will cover us all; then it too in its turn will change; and what it changes to, will change again {199} and again for ever; and again change after change to infinity. The waves of change and transformation--if a man think of them and of their speed, he will despise everything mortal. "The universal cause is like a winter torrent; it carries all before it. How cheap then these poor statesmen, these who carry philosophy into practical affairs, as they fancy--poor diminutive creatures. Drivellers. Man, what then? Do what now Nature demands. Start, if it be given thee, and look not round to see if any will know. Hope not for Plato's Republic;[5] but be content if the smallest thing advance; to compass that one issue count no little feat. "Who shall change one of their dogmata [the regular word of Epictetus]? And without a change of dogmata, what is there but the slavery of men groaning and pretending to obey? Go now, and talk of Alexander, and Philip and Demetrius of Phalerum; whether they saw the will of Nature and schooled themselves, is their affair; if they played the tragic actor, no one has condemned me to copy them. Simplicity and modesty are the work of philosophy; do not lead me astray into vanity.
