The exchange of one fear or pleasure or pain for another fear or pleasure or pain, which are measured like coins, the greater with the less, is not the exchange of virtue. O, my dear Simmias, is there not one true coin, for which all things ought to exchange?--and that is wisdom; and only in exchange for this, and in company with this, is anything truly bought or sold, whether courage or temperance or justice. ...in the true exchange, there is a purging away of all these things, and temperance, and justice, and courage, and wisdom herself are a purgation of them.
Socrates
Gay sex meant two hours of sexual pleasure in exchange for two hours of sexual pleasure. Heterosexual sex meant two hours of sexual pleasure in exchange for a lifetime of responsibility. Heterosexuality was a bad deal! The fear behind homophobia was that no one would be providing for the next generation. Everybody would be having fun. Thus fun became a sign of immaturity; hedonism in many forms became illegal.
Warren Farrell
So she said banteringly: "What's the unit of exchange in this different world of yours?"
He did not hesitate. "The tear."
"It isn't fair," she objected. "Some people have to work very hard for a tear. Others can have them just for thinking."
"What system of exchange is fair?" he cried, and his voice sounded as if he were really drunk. "And whoever invented the concept of fairness, anyway? Isn't everything easier if you simply get rid of the idea of justice altogether? You think the quantity of pleasure, the degree of suffering is constant among all men? It somehow comes out in the end? You think that? If it comes out even it's only because the final sum is zero."Paul Bowles
Fairness means not to use fraud and trickery in the exchange of commodities and services and the exchange of feelings.
Erich Fromm
All exchange stimulates productive activity, whether exchange by gift, gambling, barter, or money transaction.
Aaron C. Brown
Discussion is an exchange of knowledge; argument an exchange of ignorance.
