The profligate, then, desires all pleasant things or those that are most intensely pleasant, and is led by his desire so as to choose these in preference to all other things. And so he is constantly pained by failing to get them and by lusting after them: for all appetite involves pain; but it seems a strange thing to be pained for the sake of pleasure.

People who fall short in the matter of pleasure, and take less delight than they ought in these things, are hardly found at all; for this sort of insensibility is scarcely in human nature. And indeed even the lower animals discriminate kinds of food, and delight in some and not in others; and a being to whom nothing was pleasant, and who found no difference between one thing and another, would be very far removed from being a man. We have no name for such a being, because he does not exist.
