"Hold fast, then, to this sound and wholesome rule of life – that you indulge the body only so far as is needful for good health. The body should be treated more rigorously, that it may not be disobedient to the mind. Eat merely to relieve your hunger; drink merely to quench your thirst; dress merely to keep out the cold; house yourself merely as a protection against personal discomfort. It matters little whether the house be built of turf, or of variously coloured imported marble; understand that a man is sheltered just as well by a thatch as by a roof of gold. Despise everything that useless toil creates as an ornament and an object of beauty. And reflect that nothing except the soul is worthy of wonder; for to the soul, if it be great, naught is great. . . .
‘If you would enjoy real freedom, you must be the slave of Philosophy.’ [quoting Epicurus] The man who submits and surrenders himself to her is not kept waiting; he is emancipated on the spot. For the very service of Philosophy is freedom.” (Seneca, Moral Letter 8, “On The Philosopher’s Seclusion”)
