Affection is nothing else than love, but is what is continuous of it. For from love a man is affected either with evil and falsity, or with good and truth. As this love is present and is within all things in general and particular that belong to him, it is not perceived as love, but is varied according to its matter in hand, and according to the man’s states and their changes; and this continually in everything that he wills, thinks, and does. It is this continuous of love that is called affection; and it is this continuous that reigns in a man’s life and makes all his delight, and consequently his very life; for man’s life is nothing else than the delight of his affection; and thus is nothing else than the affection of his love. Love is man’s willing, and derivatively is his thinking, and thereby his acting.
