Parenthetically, I have a strong bias against conspiracy theories of history. I do not believe in the notion that the extreme left, the extreme right, the power elite, the establishment, oil companies, professoriat, military-industry complex, and so on, can be regarded as single decision-making units with detailed programs for imposing their will on the unsuspecting world. […] The “true believer” finds or suspects omniscient, omnipotent, and omnipresent opposition everywhere. […] Conspiracy is, of course, possible, but I believe that most times its appearance is the result of like-minded people, similarly placed, responding in the same way to the same stimulus.
