For man to be able to live he must either not see the infinite, or have such an explanation of the meaning of life as will connect the finite with the infinite.
Leo TolstoyThe most difficult subjects can be explained to the most slow- witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.
