Definition.—The passions—also called the emotions, affections, or sentiments—are acts of desire; but, unlike the acts of the will, they are directed, not to good apprehended by the higher knowing power of the intellect, but to good apprehended by the lower knowing power of sense and imagination. They are defined as: acts or movements of the sensitive appetite which arise from the representation of some good in the sense faculties, and which produce some transformation in the body, such as palpitation of the heart, increased circulation of the blood, paleness, blushing, etc.
