The cookbook gives a detailed description of ingredients and procedures but no proofs for its prescriptions or reasons for its recipes; the proof of the pudding is in the eating. ... Mathematics cannot be tested in exactly the same manner as a pudding; if all sorts of reasoning are debarred, a course of calculus may easily become an incoherent inventory of indigestible information.

Rate of change is this mathematics known as Calculus. ... Now I hope you understand this, because I've never been able to make head nor tail of it. It must be some sort of a Black Magic operation, started out by the Luce cult — some immoral people who are operating up in New York City, Rockefeller Plaza — been thoroughly condemned by the whole society. Anyway, their rate-of-change theory — I've never seen any use for that mathematics, by the way — I love that mathematics, because it — I asked an engineer, one time, who was in his 6th year of engineering, if he'd ever used Calculus, and he told me yeah, once, once I did, he said. When did you use it? And he said I used it once. Let me see, what did you use it on? Oh yeah. Something on the rate-of-change of steam particles in boilers. And then we went out and tested it and found the answer was wrong.
L. Ron Hubbard
“Eating education is like eating Christmas pudding: Too much can make your stomach sore, too much can spoil your whole Christmas. Learning from a man who learned all he learned from another, can lead you to a safe place, but destroy your sense of wonder. Trapped inside a book, locked inside a lecture, when do you find the time to love and spend your days in forests? And when ideals are fleeting ~ tell me then who do you turn to? They prove to you that God is dead, but to them you’re just a number.”
