Supposing in example sentence
But supposing the beauty equal on both sides, it does not follow that the inclinations must be therefore alike, for it is not every beauty that excites love, some but pleasing the eye without winning the affection; and if every sort of beauty excited love and won the heart, the will would wander vaguely to and fro unable to make choice of any; for as there is an infinity of beautiful objects there must be an infinity of inclinations, and true love, I have heard it said, is indivisible, and must be voluntary and not compelled.
