The mechanism whereby the mind, appraising, foreseeing and judging, checks the first movement of impulse, is inhibition or repression. Without inhibition moral conduct would not be possible. The mind would have no method of indicating the path and prescribing rules to the organism's instinct. It would have no means of making its insight prevail over the desires of the senses. It would have no weapon with which to force its being to actions opposed to its organic inclinations. Without inhibition the individual would never give precedence to the demands of the community and lay himself open to disagreeable emotions in order to please the community. Inhibition was the necessary organic preliminary to the phenomenon of Morality. It had to be pre-existent in the individual, so that Morality could make itself at home in his intellectual life, so that it could acquire creative, ruling and practical power among the elect, and become an unconscious and easy habit among the average. Morality took possession of a pre-existent organic aptitude and made it serve its own purposes. But organic aptitudes are not alike in all individuals. In some cases they are more or less perfect; in others they may be lacking altogether. Indeed only individuals with highly developed powers of inhibition are capable of that heroic Morality which liberates them from the weakness of the flesh and makes them independent of the demands of the body; those in whom this power of inhibition is scantily developed evade the influence of Morality entirely, and it has no authority over them.
