Whether the contrariety of the irascible passions is based on the contrariety of good and evil?

❌ Objection 1 : It would seem that the contrariety of the irascible passions is based on no other contrariety than that of good and evil. For the irascible passions are ordained to the concupiscible passions, as stated above (Article [1], ad 1). But the contrariety of the concupiscible passions is no other than that of good and evil; take, for instance, love and hatred, joy and sorrow. Therefore the same applies to the irascible passions.

❌ Objection 2 : Further, passions differ according to their objects; just as movements differ according to their termini. But there is no other contrariety of movements, except that of the termini, as is stated in Phys. v, 3. Therefore there is no other contrariety of passions, save that of the objects. Now the object of the appetite is good or evil. Therefore in no appetitive power can there be contrariety of passions other than that of good and evil.

❌ Objection 3 : Further, "every passion of the soul is by way of approach and withdrawal," as Avicenna declares in his sixth book of Physics. Now approach results from the apprehension of good; withdrawal, from the apprehension of evil: since just as "good is what all desire" (Ethic. i, 1), so evil is what all shun. Therefore, in the passions of the soul, there can be no other contrariety than that of good and evil.
