Context

“Contempt is the conception of anything which touches the mind so little, that its presence leads the mind to imagine those qualities which are not in it rather than such as are in it (cf. III. lii. note) . The definitions of veneration and scorn I here pass over, for I am not aware that any emotions are named after them. VI. Love is pleasure, accompanied by the idea of an external cause. Explanation—This definition explains sufficiently clearly the essence of love; the definition given by those authors who say that love is the lover's wish to unite himself to the loved object expresses a property, but not the essence of love;” source
