Causes: As important a fact as any individual cause on earth is the vital incapacity of the human individual to distinguish between genuine cause and one which is foisted upon him by pressure, environment, propaganda, conditioning.If people had the sense they pretend to have, they would seek this fundamental distinction perceptible.Hardly anyone makes this effort. This is partly because it is an invisible but powerful part of their culture to teach that conditioned emotionality and ‘causes’ whose necessity, urgency or rightness is only conditioned into them, are necessarily, right.
