If knowledge means so much to us, “What is knowledge?” the reader asks. We can give only a negative answer. Knowledge is not instruction, information, scholarship, a well-stored memory. It is passed, like the light of a torch, from mind to mind, and the flame can be kindled at original minds only. Thought, we know, breeds thought; it is as vital thought touches our minds that our ideas are vitalized, and out of our ideas comes our conduct of life. (Philosophy of Education, p. 303)
