[213] Happiness comes from within, not from without. The true seat of happiness is the mind. Compare Milton, "Paradise Lost," Book i. 254, 255:-- "The mind is its own place, and in itself Can make a Heaven of Hell, a Hell of Heaven." [214] Homeric Epigrammata, xiii. 5. [215] Wyttenbach thinks these lines are by Menander. Plutarch quotes them again "On Contentedness of Mind," Sec. xi. [216] Hesiod, "Works and Days," 705. [217] Plato, "Republic," ix. p. 571, D. Quoted again, "How one may be aware of one's Progress in Virtue," Sec. xii. [218] And so Dr. Young truly says,-- "A man of pleasure is a man of pains." _Night Thoughts._ ON MORAL VIRTUE. Sec. I. I propose to discuss what is called and appears to be moral virtue (which differs mainly from contemplative virtue in that it has emotion for its matter, and reason for its form), what its nature is, and how it subsists, and whether that part of the soul which takes it in is furnished with reason of its own, or participates in something foreign, and if the latter, whether as things that are mixed with something better than themselves, or rather as that which is subject to superintendence and command, and may be said to share in the power of that which commands. For I think it is clear that virtue can exist and continue altogether free from matter and mixture. My best course will be to run briefly over the views of others, not so much to display my research as because, when their ideas have been set forth, mine will become more clear and be on a firmer basis.
