Casanova advises, "There is no honest woman with an uncorrupted heart whom a man is not sure of conquering by dint of gratitude. It is one of the surest and shortest means."[100] Alcohol and violence, for him, were not proper tools of seduction.[101] Instead, attentiveness and small favors should be employed to soften a woman's heart, but "a man who makes known his love by words is a fool". Verbal communication is essential—"without speech, the pleasure of love is diminished by at least two-thirds"—but words of love must be implied, not boldly proclaimed.[100]
