That which is called character is at bottom the name we give to the power of inhibition. Where it is weak we speak of lack of character, whereas by strength of character we mean that the power of inhibition is great. The will makes use of inhibition. With its help the will guides the living machine in a certain direction and urges it to perform given tasks. At the first glance it may not seem obvious that positive actions can come of repression, which is something negative. But if we analyse psychologically the actions demanded and promoted by the will, and trace them back to their organic origins, we shall find that, as a rule, the first elements consist in the prevention of impulsive movements, and that the impetus to positive effort is given by the will, which converts these movements into contrary ones. A few instances may make this psychic process clearer. Winkelried, at Sempach, cleaves a path through the cuirassiers while they bury their lances in his breast; he becomes capable of this great deed of self-sacrifice in that, by a mighty effort of will power, he suppresses the strongest of all instincts, that of self-preservation, and forces all his energies, which are naturally directed towards flight from danger, to challenge danger and yield completely to it. The lover who overcomes his passion and renounces its object, because his idol is the bride of his best friend, begins with the determined inhibition of the impulse which urges him towards the woman, and attains renunciation by the suppression of his desire; this renunciation finds expression in positive actions, in the rupture of relations which bring him happiness, the avoidance of meetings which would prevent the wound in his heart from healing, and so on. The brave rescuer who plunges into the waves to save a drowning man, or enters a burning house to save a fellow creature threatened by the flames, must first overcome his natural shrinking fear of the water and the fire; and not till after the suppression of strong impulses to avoid the uncanny adventure, does he succeed in making his muscles obey the impulse to save life.
