Gentleness

There are no people more constant and steadfast in doing good than those who are gentle and good-natured, just as, on the contrary, those who allow themselves to give in to anger and the passions of the irascible appetite are usually very fickle because they act only on impulse and fits of anger. They're like mountain streams, strong and impetuous only when they overflow, but which dry up as soon as their waters are drained; whereas rivers, which represent good-natured people, flow quietly, tranquilly, and never dry up. (SV XI, 54)
