“Man is so complicated a machine that it is impossible to get a clear idea of the machine beforehand, and hence impossible to define it. For this reason, all the investigations have been vain, which the greatest philosophers have made à priori, that is to to say, in so far as they use, as it were, the wings of the spirit. Thus it is only à posteriori or by trying to disentangle the soul from the organs of the body, so to speak, that one can reach the highest probability concerning man's own nature, even though one can not discover with certainty what his nature is.”

“The impossibility of outraging nature is the greatest anguish man can know.”

“Man is a machine which reacts blindly to external forces and, this being so, he has no will, and very little control of himself, if any at all. What we have to study, therefore, is not psychology-for that applies only to a developed man-but mechanics. Man is not only a machine but a machine which works very much below the standard it would be capable of maintaining if it were working properly.”

“Late twentieth-century machines have made thoroughly ambiguous the difference between natural and artificial, mind and body, self-developing and externally designed, and many other distinctions that used to apply to organisms and machines. Our machines are disturbingly lively, and we ourselves frighteningly inert.”

“Man is a machine, but a very peculiar machine. He is a machine which, in right circumstances, and with right treatment, can know that he is a machine, and having fully realized this, he may find the ways to cease to be a machine.First of all, what man must know is that he is not one; he is many. He has not one permanent and unchangeable “I” or Ego. He is always different. One moment he is one, another moment he is another, the third moment he is a third, and so on, almost without end.”

“Cesar is not a philosophical man. His life has been one long flight from reflection. At least he is clever enough not to expose the poverty of his general ideas; he never permits the conversation to move toward philosophical principles. Men of his type so dread all deliberation that they glory in the practice of the instantaneous decision. They think they are saving themselves from irresolution; in reality they are sparing themselves the contemplation of all the consequences of their acts. Moreover, in this way they can rejoice in the illusion of never having made a mistake; for act follows so swiftly on act that it is impossible to reconstruct the past and say that an alternative decision would have been better. They can pretend that every act was forced on them under emergency and that every decision was mothered by necessity”
