The inner censor of the mind of the true believer completes the work of the public censor; his self-discipline is as tyrannical as the obedience imposed by the regime; he terrorizes his own conscience into submission;he carries his private Iron Curtain inside his skull, to protect his illusions against the intrusion of reality.
Arthur KoestlerLearn from the mistakes of others. You can't live long enough to make them all yourself. Boredom sets into boring minds. The more original a discovery, the more obvious it seems afterwards.
Arthur KoestlerI have repeatedly stressed that the selfish impulses of man constitute a much less historic danger than his integrative tendencies. To put it in the simplest way: the individual who indulges in an excess of aggressive self-assertiveness incurs the penalties of society-he outlaws himself, he contracts out of the hierarchy. The true believer, on the other hand, becomes more closely knit into it; he enters the womb of his church, or party, or whatever the social holon to which he surrenders his identity.
Arthur KoestlerAs modern physics started with the Newtonian revolution, so modern philosophy starts with what one might call the Cartesian Catastrophe. The catastrophe consisted in the splitting up of the world into the realms of matter and mind, and the identification of 'mind' with conscious thinking. The result of this identification was the shallow rationalism of l' esprit Cartesien, and an impoverishment of psychology which it took three centuries to remedy even in part.
Arthur KoestlerIn the social equation, the value of a single life is nil; in the cosmic equation, it is infinite... Not only communism, but any political movement which implicitly relies on purely utilitarian ethics, must become a victim to the same fatal error. It is a fallacy as naïve as a mathematical teaser, and yet its consequences lead straight to Goya's Disasters, to the reign of the guillotine, the torture chambers of the Inquisition, or the cellars of the Lubianka.
