Allow man to believe he is one, whereas he is actually composed of a multitude of "I's": the rebellious "I", the anger "I", the "I" that wants to evolve, the happy "I", etc. Buffers prevent us from seeing our contradictions or allow us to accept them as something normal. An example: someone who considers himself to be a calm person but who becomes angry at the slightest annoyance. But the justifications he finds for his anger give him the illusion of being consistent.
