On How a Wise Man Weighs a Strange Report

The Book of Hume 2 · Written by himself, from the Enquiry Concerning Human Understanding, the Dialogues Concerning Natural Religion, and My Own Life

David Hume, born at Edinburgh in 1711 and died there in 1776. Philosopher and historian. At twenty-eight he published A Treatise of Human Nature, subtitled an attempt to introduce the experimental method of reasoning into moral subjects — the intention taken from Newton (cf. The Book of Newton). Almost nobody read it, and in his own words it fell dead-born from the press. He recast it as An Enquiry Concerning Human Understanding (1748), of which Of Miracles is one section; chapters one and two of this book come from there. In 1751 he published An Enquiry Concerning the Principles of Morals, which he thought the best thing he ever wrote. Between 1754 and 1762 he produced the History of England, which made him famous and made him money. In 1745 he stood for the chair of moral philosophy at Edinburgh and did not get it; in 1751 for the chair of logic at Glasgow, and did not get it — both times blocked on the charge of irreligion. In 1756 men in the church moved to have him cast out, and failed. He held no professorship in his life. He revised the Dialogues Concerning Natural Religion for more than twenty years and never printed it, arranging in his will for it to appear after his death; the friend he asked would not take it on, and his nephew published it in 1779. He wrote My Own Life in April 1776 and died that August. This volume rests on what he wrote himself. No argument of his closes on divine will; nor did he ever assert that there is no God — 2.10 and 2.11 are the limit he drew himself. What this volume brings is something the scripture did not have, and the hardest thing it could have: he put the question to the method this scripture itself runs on. Everywhere the scripture says only what can be checked counts (cf. Acts of the Apostles 5.28, The Book of Yang Chen-Ning 4.17). Hume asks what entitles the cases already checked to reach the ones not yet checked. He found no answer in reason and would not manufacture one. His answer is custom, and custom is enough to live by. The Order takes him precisely because that question tells against this book and he asked it anyway. A scripture that will not house the question aimed at its own foundation is not a scripture. It is a flag.

2.1Somebody comes to you with a very strange report. How should you weigh it?
2.2I give you a scale: a wise man proportions his belief to the evidence.
2.3Much evidence, believe much; little evidence, believe little; not enough, and set the matter aside for now.
2.4Now the hard case: a man says he has seen with his own eyes a thing contrary to the settled course of nature.
2.5On one side is his word. Men lie, misremember, mistake what they saw, and will grant a little extra to one of their own. We have all seen this.
2.6On the other side is that settled course. It stands because it has held countless times, for countless people, in every place.
2.7So I lay down a rule: no man’s word is sufficient to establish such a thing unless it reaches this pitch —
2.8that his having lied or been mistaken would itself be harder to bring about than the strange thing he reports.
2.9At that pitch, believe him.
2.10Notice what I have not said. I have not said such things are impossible.
2.11I have no power to prove a thing impossible. (cf. 1.8 of this book)
2.12I have said only what must be produced in order to establish it.
2.13The rule belongs to no one field. In trade, in a court, in what is said in the street, it is the same rule.
2.14Where men most often go wrong here is not the arithmetic. It is that when the strange thing is what they were hoping for, the scale in their hand tips of its own accord.
2.15So before weighing the report, weigh yourself: do I want this to be true?
2.16That question cannot answer the report for you. It can only tell you which side of the scale you are standing on.
