According to Thomas Aquinas, does "love" towards something always bring "desire" towards that something?
A sensitive appetite (i.e., an appetite pertaining to the senses) can be concupiscible or irascible. St. Thomas says (ibid. I q. 81 a. 2 c.) that the concupiscible appetitite is that
through which the soul is simply inclined to seek what is suitable, according to the senses, and to fly from what is hurtful
The irascible is that
whereby an animal resists these attacks that hinder what is suitable, and inflict harm
When you say "desire," it seems you mean what St. Thomas calls desire/cupidity or desiderium/cupiditas (cf. ibid. I-II q. 40 a. 1).
Hope might be the irascible analogue of "love" that you're looking for (cf. the aforementioned article).
