Since temperance consists in self-knowledge, neither of these professional men, as such, is temperate: their professions are of a vulgar cast, and do not belong to the virtuous life.[23] How are we to know our own minds? We know it by looking into another mind, and into the most rational and divine portion thereof: just as the eye can only know itself by looking into another eye, and seeing itself therein reflected.[24] It is only in this way that we can come to know ourselves, or become temperate: and if we do not know ourselves, we cannot even know what belongs to ourselves, or what belongs to others: all these are branches of one and the same cognition. We can have no knowledge of affairs, either public or private: we shall go wrong, and shall be unable to secure happiness either for ourselves or for others. It is not wealth or power which are the conditions of happiness, but justice and temperance. Both for ourselves individually, and for the public collectively, we ought to aim at justice and temperance, not at wealth and power. The evil and unjust man ought to have no power, but to be the slave of those who are better than himself.[25] He is fit for nothing but to be a slave: none deserve freedom except the virtuous.

Are you worthy of freedom? _Alk._--I feel but too keenly that I am not. I cannot emerge from this degradation except by your society and help. From this time forward I shall never leave you.[26] [Footnote 26: Plato, Alkib. i. 135.] ALKIBIADES II. [Side-note: Second Alkibiades--situation supposed.] The other Platonic dialogue, termed the Second Alkibiades, introduces Alkibiades as about to offer prayer and sacrifice to the Gods. [Side-note: Danger of mistake in praying to the Gods for gifts which may prove mischievous. Most men are unwise. Unwise is the generic word: madmen, a particular variety under it.]
