Meditation 6.13

13. Surely it is an excellent plan, when you are seated before delicacies and choice foods, to impress upon your imagination that this is the dead body of a fish, that the dead body of a bird or a pig; and again, that the Falernian wine is grape juice and that robe of purple a lamb's fleece dipped in a shell-fish's blood; and in matters of sex intercourse, that it is attrition of an entrail and a convulsive expulsion of mere mucus. Surely these are excellent imaginations, going to the heart of actual facts and penetrating them so as to see the kind of things they really are. You should adopt this practice all through your life, and where things make an impression which is very plausible, uncover their nakedness, see into their cheapness, strip off the profession on which they vaunt themselves. For pride is an arch-seducer of reason, and just when you fancy you are most certainly busy in good works, then you are most certainly the victim of imposture. Consider for instance what Crates says even about Xenocrates.
