Asks question of Class

Do not suppose that I was a very deep thinker, or was marked as a precocious person. I was a very lively imaginative person, and could believe in the Arabian Nights as easily as in the Encyclopaedia. But facts were important to me, and saved me. I could trust a fact, and always cross- examined an assertion. So when I questioned Mrs. Marcet's book by such little experiments as I could find means to perform, and found it true to the facts as I could understand them, I felt that I had got hold of an anchor in chemical knowledge, and clung fast to it. Michael Faraday, 1858 National Portrait Gallery

When someone says science teaches such and such, he is using the word incorrectly. Science doesn't teach it; experience teaches it. If they say to you science has shown such and such, you might ask, "How does science show it - how did the scientists find out - how, what, where?" Not science has shown, but this experiment, this effect has shown. Learn from science that you must doubt the experts… Science is the belief in the ignorance of experts. (to Nat’l Science Teachers Assn. 1966) Why quote Feynman? No. Because what he says makes sense. Because he is an expert?

On his scholastic Cambridge tutors: "Men of sharp wits, shut up in their cells of a few authors, chiefly Aristotle, their Dictator." Shakespeare ( ) All the philosophy of nature which is now received, is either the philosophy of the Grecians, or that other of the alchemists … The one is gathered out of a few vulgar observations, and the other out of a few experiments of a furnace.

"Many will pass through and knowledge will be increased. ” Daniel 12:4

Instauratio Magna (1620) “…that wisdom which we have derived principally from the Greeks is but like the boyhood of knowledge, and has the characteristic property of boys: “…it is but a device for exempting ignorance from ignominy.” “…the end which this science of mine proposes is the invention not of arguments but of arts.” “…not so much by instruments as by experiments …skilfully and artificially devised for the express purpose of determining the point in question.” “restoration of learning and knowledge” it can talk, but it cannot generate;”
