Division.—There are two classes of passions; (a) the concupiscible, which have as their object sensible good considered as delightful, or sensible evil considered as unpleasant, and which are love and hatred, desire and flight, delight and sadness; (b) the irascible, which have as their object sensible good or sensible evil considered as difficult to attain or to avoid, and which are hope and despair, boldness and fear, anger.

The concupiscible passions are defined as follows: (a) love, the first of the passions and the cause of all the others, tends to sensible good considered as desirable, abstracting from its presence or absence; while hatred is the aversion from sensible evil considered precisely as unsuitable and abstracting from its presence or absence; (b) desire tends to sensible good that is absent, and flight turns away from sensible evil apprehended as future; (c) delight is the affection produced in the sensitive appetite by the presence and possession of the object desired; (d) sadness is the passion which dejects the soul on account of the presence of an evil.

The irascible passions are explained as follows: (a) hope reaches out towards a future good whose attainment is difficult, but not impossible; despair turns away from a good that seems impossible of attainment; (b) bravery goes out to attack an evil that seems difficult and imminent, but not unconquerable; fear falls back before a future difficulty that seems irresistible; (e) anger is the desire of vengeance for an injury received.
