Affections

How do "affections" differ from "emotions" or "feelings"?

Perhaps it would be best to say that whereas affections are not less than emotions, they are surely more. Emotions can often be no more than physiologically heightened states of either euphoria or fear that are unrelated to what the mind perceives as true.
Affections, on the other hand, are always the fruit or effect of what the mind understands and knows. The will or inclination is moved wither toward or away from something that is perceived by the mind. An emotion or mere feeling, on the other hand, can rise or fall independently of and unrelated to anything in the mind. One can experience an emotion or feeling without it properly being an affection, but one can rarely if ever experience an affection without it being emotional and involving intense feelings that awaken and move and stir the body.
