Alcohol is not likely to bring out any impulse that is not already potential in a personality, nor is it likely to cast behavior into patterns for which there is not already significant subsurface predilection. The alcohol merely facilitates expression by narcotizing inhibitory processes. […] The oil which lubricates the engine of an automobile neither furnishes the energy for its progress nor directs it.

Hervey Cleckley (1903-1984) American psychiatrist, academic
