Mises on Force and Persuasion

Liberalism in the Classical Tradition by Ludwig von Mises, p 51

Repression by brute force is always a confession of the inability to make use of the better weapons of the intellect

This is similar to Godwin:

If he who employs coercion against me could mould me to his purposes by argument, no doubt he would. He pretends to punish me because his argument is strong; but he really punishes me because his argument is weak.
