Pleasure and pain Quotes

After these matters we ought perhaps next to discuss pleasure. For it is thought to be most intimately connected with our human nature, which is the reason why in educating the young we steer them by the rudders of pleasure and pain; it is thought, too, that to enjoy the things we ought and to hate the things we ought has the greatest bearing on virtue of character. For these things extend right through life, with a weight and power of their own in respect both to virtue and to the happy life, since men choose what is pleasant and avoid what is painful; and such things, it will be thought, we should least of all omit to discuss, especially since they admit of much dispute.

Aristotle

When we examine the acts of an individual, we shall find them compulsory. He is compelled to do them and has no freedom of choice. In a sense, he is like a stew cooking on a stove; it has no choice but to cook. And it must cook because Providence has harnessed life with two chains: pleasure and pain (...) there is no difference here between man and animal. And if that is the case, there is no free choice whatsoever, but a pulling force, drawing them toward any bypassing pleasure and rejecting them from painful circumstances. And Providence leads them to every place it chooses by means of these two forces [i.e. pleasure and pain], without asking their opinion in the matter.
