The intellect alone has an eye for viewing an essence, which it cannot see except in the true Cause, which is the Fount of all desire. Moreover, since all things seek to exist, then in all things there is desire from the Fount-of-desire, wherein being and desire coincide in the Same.
Nicholas of CusaA given circle cannot be so true that a truer one cannot be found; and the movement of a sphere at one moment is never precisely equal to its movement at another, nor does it ever describe two circles similar and equal, even if from appearances the opposite may seem true.
Nicholas of CusaThe world has no circumference. It would certainly have a circumference if it had a centre, in which case it would contain within itself its own beginning and end; and that would mean that there was some other thing which imposed a limit to the world - another being existing in space outside the world. All of these conclusions are false. Since, then, the world cannot be enclosed within a material circumference and centre, it is unintelligible without God as its centre and circumference.
Nicholas of CusaNothing could be more beneficial for even the most zealous searcher for knowledge than his being in fact most learned in that very ignorance which is peculiarly his own; and the better a man will have known his own ignorance, the greater his learning will be.
