“For Plato, the quickening of the heart that occurred when a person saw his or her loved one was just a step in the ascent to true love, which could happen only in the mind, after the lover comprehended what was eternally true and beautiful in the beloved. Platonic love existed beyond all the blood and heat contained in the heart. This split between passion and piety, between lust and love, would resonate throughout the Middle Ages and the Renaissance, and it continues up to the present day.”
