"When you aren't sincere you need to pretend, and by pretending you end up believing yourself; that's the basic principle of every faith."

From somewhere, back in my youth, heard Prof say, 'Manuel, when faced with a problem you do not understand, do any part of it you do understand, then look at it again.' He had been teaching me something he himself did not understand very well—something in math—but had taught me something far more important, a basic principle.
