The Greeks believed thumos was essential to andreia — manliness. It is mentioned over seven hundred times in the Iliad and the Odyssey. Philosopher Allan Bloom called it “the central natural passion in men’s souls.” If we have lost the ability to recognize, appreciate, cultivate, and utilize one of the three main components of our nature, we should not be surprised when negative consequences follow. When one hears of a lack of virility, fight, energy, and ambition in modern men, of a malaise of spirit that has settled over our sex, what is really being spoken of is a shortage of thumos. For millions of men, thumos lies dormant, an energy source left untapped.
