Hume also related courage and joy to have positive effects on the soul: "(...) since the soul, when elevated with joy and courage, in a manner seeks opposition, and throws itself with alacrity into any scene of thought or action, where its courage meets with matter to nourish and employ it". Along with courage nourishing and employing, Hume also wrote that courage defends humans in the Treatise: "We easily gain from the liberality of others, but are always in danger of losing by their avarice: Courage defends us, but cowardice lays us open to every attack".
