Whether love is the first of the concupiscible passions?

Objections

Objection 1 : It would seem that love is not the first of the concupiscible passions. For the concupiscible faculty is so called from concupiscence, which is the same passion as desire. But "things are named from their chief characteristic" (De Anima ii, 4). Therefore desire takes precedence of love.
Objection 2 : Further, love implies a certain union; since it is a "uniting and binding force," as Dionysius says (Div. Nom. iv). But concupiscence or desire is a movement towards union with the thing coveted or desired. Therefore desire precedes love.
Objection 3 : Further, the cause precedes its effect. But pleasure is sometimes the cause of love: since some love on account of pleasure (Ethic. viii, 3,4). Therefore pleasure precedes love; and consequently love is not the first of the concupiscible passions.
