Context

“But if he be changed from that disposition, the memory of that pleasure does not give him pleasure, but distaste: for instance, the memory of food in respect of a man who has eaten to repletion. Reply Obj. 1: When pleasure is perfect, then it includes complete rest; and the movement of desire, tending to what was not possessed, ceases. But when it is imperfect, then the desire, tending to what was not possessed, does not cease altogether. Reply Obj. 2: That which is possessed imperfectly, is possessed in one respect, and in another respect is not possessed.” source
