The greatest temptation for the like of us is: to renounce violence, to repent, to make peace with oneself. Most revolutionaries fell before this temptation, from Spartacus to Danton and Dostoevsky; they are the classical form of betrayal of the cause.

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.
