On a Candle

The Book of Faraday 3 · Written by himself, from the Experimental Researches, the Christmas Lectures, and his laboratory record

Michael Faraday, born at Newington south of London in 1791, died at Hampton Court in 1867. His family was poor and he left school at thirteen for a bookbinder’s shop; the books he bound he read, one after another. In 1831 he found electromagnetic induction, on which every generator since has rested. He set out the two laws of electrolysis, saw that magnetism turns light, saw that matter can be repelled by a magnet, and was the first to speak of a field. He refused a knighthood, and refused to work on poison gas for the Crimean war. He wrote his own: three volumes of Experimental Researches, a Chemical History of a Candle taken down from the Christmas Lectures, and a laboratory record of more than sixteen thousand entries — every one numbered by his own hand, dated by his own hand, indexed by his own hand, and the failures set down along with the rest. All his life he belonged to a very small sect and served as an elder in it and attended every week. Yet in his work he never cited scripture and never closed an argument by appeal to divine will; asked to speak on religion where he lectured, he declined. Like Newton he kept two rooms; the difference is that Newton wrote in the other one and sat there longer (cf. The Book of Newton 4), while this man only went, and kept, and served there, and wrote almost nothing. Further: he never learned mathematics. What he saw was afterwards written in equations by another man, and only then was it fully in hand. The Order sets this down not to reduce him but to keep the record whole: a man may go very far on looking and recording alone, and the last stretch of the road often takes a different faculty. Lastly: his memory failed in his forties, and for more than twenty years afterwards it came and went, and for some years he could hardly work at all. He did not stop.

3.1Every Christmas I gave a course for children. I did it for nineteen years.
3.2One year I took nothing but a candle.
3.3I lit a candle and set it in front of them and asked: what is here?
3.4Why does the wax not all melt at once? How is that little cup at the top held in place?
3.5Why does the wick not burn away?
3.6What is inside the flame? The part in the middle is darker than the outside — why?
3.7Where does what is burnt away go? We hold a cold flask over it and there is water on the glass. Where did that water come from?
3.8The air we breathe out and the air this candle gives off — are they the same thing?
3.9I asked it step by step, and step by step I did it in front of them.
3.10At the end I said one thing to them:
3.11There is not a law by which this world is governed that does not show its face somewhere in this one candle.
3.12Let me state the rule I kept in doing this.
3.13I never made the talk shallow because the listeners were children.
3.14I made it clear. Clear and shallow are not the same thing.
3.15Shallow is taking the hard part out. Clear is laying the hard part down step by step so that a person can climb it.
3.16When a man says he cannot make a thing clear because his listeners are not up to it, it is usually that he has not yet got it clear himself.
3.17If you have really understood a thing, you can take a candle and explain it to a child.
