Whether pleasure perfects operation?

❌ Objection 1 : It would seem that pleasure does not perfect operation. For every human operation depends on the use of reason. But pleasure hinders the use of reason, as stated above (Article [3]). Therefore pleasure does not perfect, but weakens human operation.

❌ Objection 2 : Further, nothing perfects itself or its cause. But pleasure is an operation (Ethic. vii, 12; x, 4), i.e. either in its essence or in its cause. Therefore pleasure does not perfect operation.

❌ Objection 3 : Further, if pleasure perfects operation, it does so either as end, or as form, or as agent. But not as end; because operation is not sought for the sake of pleasure, but rather the reverse, as stated above (Question [4], Article [2]): nor as agent, because rather is it the operation that causes pleasure: nor again as form, because, according to the Philosopher (Ethic. x, 4), "pleasure does not perfect operation, as a habit does." Therefore pleasure does not perfect operation.
