The affections and passions are frequently spoken of as the same; and yet, in the more common use of speech, there is in some respect a difference. Affection is a word, that, in its ordinary signification, seems to be something more extensive than passion, being used for all vigorous lively actings of the will or inclination; but passion is used for those that are more sudden, and whose effects on the animal spirits are more violent, the mind being more overpowered, and less in its own command.
