For Pythagoras, philosophy was not abstract; it was therapeutic. The soul was in a state of dissonance, and through askesis (practice)—Like studying mathematics and music—it could be returned to harmony. The courage to begin is not a one-time event but a daily practice of tuning. It is the courage to silence the noise of the world, to listen for your fundamental note, and to have the discipline to adjust your starlings each day. Courage is the maintenance of harmony against the entropy of fear.
