All soul is immortal. For that which is always in movement is immortal; that which moves something else, and is moved by something else, in ceasing from movement ceases from living. So only that which moves itself, because it does not abandon itself, never stops moving. But it is also source and first principle of movement for the other things which move.
Their military training will ensure success in war, but they must maintain unity by not allowing the state to grow to large, and by ensuring that the measures for promotion and demotion from one class to another are carried out. Above all they must maintain the educational system unchanged; for on education everything else depends, and it is an illusion to imagine that mere legislation without it can effect anything of consequence.
We see many instances of cities going down like sinking ships to their destruction. There have been such wrecks in the past and there surely will be others in the future, caused by the wickedness of captains and crews alike. For these are guilty men, whose sin is supreme ignorance of what matters most.
Human beings have Love for one another inborn in them - Love, reassembler of our ancient nature, who tries to make one out of two and to heal human nature.
Is it not also true that no physician, in so far as he is a physician, considers or enjoins what is for the physician's interest, but that all seek the good of their patients? For we have agreed that a physician strictly so called, is a ruler of bodies, and not a maker of money, have we not?

Had he learned by rules of art, he would have known how to speak not of one theme only, but of all; and therefore God takes away the minds of poets, and uses them as his ministers, as he also uses diviners and holy prophets, in order that we who hear them may know them to be speaking not of themselves who utter these priceless words in a state of unconsciousness, but that God himself is the speaker, and that through them he is conversing with us.
For the man who makes everything that leads to happiness, or near to it, to depend upon himself, and not upon other men, on whose good or evil actions his own doings are compelled to hinge,--such a one, I say, has adopted the very best plan for living happily. This is the man of moderation; this is the man of manly character and of wisdom.
The true lover of learning then must his earliest youth, as far as in him lies, desire all truth.... He whose desires are drawn toward knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasures I mean, if he be a true philosopher and not a sham one ... Then how can he who has the magnificence of mind and is the spectator of all times and all existence, think much of human life He cannot. Or can such a one account death fearful No indeed.
