Book Quote by Robert Grudin
““Few fallacies are more dangerous or easier to fall into than that by which, having read a given book, we assume that we will continue to know its contents permanently, or having mastered a discipline in the past, we assume that we control it in the present. Philosophically speaking, "to learn" is a verb with not legitimate tense.””
