"Sincere and strong love is greatly gratified and delighted in the prosperity of the beloved object; and if the love be perfect, the greater the prosperity of the beloved is, the more is the lover pleased and delighted; for the prosperity of the beloved is, as it were, the food of love, and therefore the greater that prosperity, the more richly is love feasted." ? Jonathan Edwards, Heaven, A World of Charity Or Love, Northampton, England, 1738. This book is dedicated to those who love and to those who love liberty.
