Constancy in love

Constancy in love is a perpetual inconstancy, which makes our hearts fasten in succession in all the qualities of the person we love, preferring now one, now another - so that such constancy is merely inconstancy contained in and confined to a single object

There are two kinds of constancy in love. One is due to the fact that we are continually finding new things to love in the person we love; the other is due to the fact that we make it a point of honor to be constant.
