Clues and Evidence

“While playing the part of the detective the investigator follows clues, but having captured his alleged fact, he turns judge and examines the case by means of logically arranged evidence. Both functions are equally essential but they are different.”

Michael_Faraday

Wonderful Dream

“All this is a dream. Still, examine it by a few experiments. Nothing is too wonderful to be true, if it be consistent with the laws of nature; and in such things as these, experiment is the best test of such consistency.”

  • Notes: This has sometimes been quoted partially as “Nothing is too wonderful to be true”, and can be seen engraved above the doorway of the south entrance to the Humanities Building at UCLA in Los Angeles, California.

Assertion Duties

“A man who makes assertions, or draws conclusions, regarding any given case, ought to be competent to investigate it. He has no right to throw the onus on others, declaring it their duly to prove him right or wrong. His duty is to demonstrate the truth of that which he asserts, or to cease from asserting. The men he calls upon to consider and judge have enough to do with themselves, in the examination, correction, or verification of their own views. The world little knows how many of the thoughts and theories which have passed through the mind of a scientific investigator have been crushed in silence and secrecy by his own severe criticism and adverse examination; that in the most successful instances not a tenth of the suggestions, the hopes, the wishes, the preliminary conclusions have been realized.”

Laws of Nature

“The laws of nature, as we understand them, are the foundation of our knowledge in natural things. So much as we know of them has been developed by the successive energies of the highest intellects, exerted through many ages. After a most rigid and scrutinizing examination upon principle and trial, a definite expression has been given to them; they have become, as it were, our belief or trust. From day to day we still examine and test our expressions of them. We have no interest in their retention if erroneous. On the contrary, the greatest discovery a man could make would be to prove that one of these accepted laws was erroneous, and his greatest honour would be the discovery.”

James_Randi

Science Is Best Defined

“Science is best defined as a careful, disciplined, logical search for knowledge about any and all aspects of the universe, obtained by examination of the best available evidence and always subject to correction and improvement upon discovery of better evidence. What's left is magic. And it doesn't work.”

Bertrand_Russell

Persecution Used In Theology

“Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So, whenever you find yourself getting angry about a difference of opinion, be on your guard, you will probably find, on examination, that your belief is going beyond what the evidence warrants.”

Extraordinary Claims

“What counts is not what sounds plausible, not what we would like to believe, not what one or two witnesses claim, but only what is supported by hard evidence rigorously and skeptically examined. Extraordinary claims require extraordinary evidence.”

Science Is Not Perfect

“[Science] is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. ... The obvious is sometimes false; the unexpected is sometimes true.”

Herbert_Simon

Invisible Hand

“In examining the processes of social coordination, economics has given top billing sometimes almost exclusive billing to the market mechanism. It is indeed a remarkable mechanism... The optimality theorems stretch credibility, so far as real-world markets are concerned, because they require substantive rationality of the kinds we found implausible in our examination of the theory of the firm. Markets populated by consumers and producers who satisfice instead of optimizing do not meet the conditions on which the theorems rest.”

Adam_Smith

Three Great Orders

“The whole annual produce of the land and labour of every country... naturally divides itself, it has already been observed, into three parts; the rent of land, the wages of labour, and the profits of stock; and constitutes a revenue to three different orders of people; to those who live by rent, to those who live by wages, and to those who live by profit. These are the three great, original, and constituent orders of every civilised society... The interest of the first of those three great orders, it appears from what has been just now said, is strictly and inseparably connected with the general interest of the society. Whatever either promotes or obstructs the one, necessarily promotes or obstructs the other... The interest of the second order, that of those who live by wages, is as strictly connected with the interest of the society as that of the first... Employers constitute the third order, that of those who live by profit. It is the stock that is employed for the sake of profit which puts into motion the greater part of the useful labour of every society... But the rate of profit does not, like rent and wages, rise with the prosperity and fall with the declension of the society. On the contrary... The interest of this third order, therefore, has not the same connection with the general interest of the society as that of the other two... The interest of the dealers... is always in some respects different from, and even opposite to, that of the public. To widen the market and to narrow the competition... The proposal of any new law or regulation of commerce which comes from this order ought always to be listened to with great precaution, and ought never to be adopted till after having been long and carefully examined, not only with the most scrupulous, but with the most suspicious attention. It comes from an order of men whose interest is never exactly the same with that of the public, who have generally an interest to deceive and even to oppress the public, and who accordingly have, upon many occasions, both deceived and oppressed it.”

Fighting AI

“We can’t fight AI without fighting ourselves. The harms to people and to society that may follow from our relationship to ‘intelligent’ machines are not foreign assaults, but symptoms of an internal disorder: a fully human pathology that requires collective self-examination, critique, and most of all, healing.”

Alfred_Wegener

Continental Drift

“The first concept of continental drift first came to me as far back as 1910, when considering the map of the world, under the direct impression produced by the congruence of the coast lines on either side of the Atlantic. At first I did not pay attention to the ideas because I regarded it as improbable. In the fall of 1911, I came quite accidentally upon a synoptic report in which I learned for the first time of palaeontological evidence for a former land bridge between Brazil and Africa. As a result I undertook a cursory examination of relevant research in the fields of geology and palaeontology, and this provided immediately such weighty corroboration that a conviction of the fundamental soundness of the idea took root in my mind.”

Egoless Programming and John von Neumann

“Programming groups who have conquered the ego problem do exist and have existed from the earliest days of computing. John von Neumann himself was perhaps the first programmer to recognize his inadequacies with respect to examination of his own work. Those who knew him have said that he was constantly asserting what a lousy programmer he was, and that he incessantly pushed his programs on other people to read for errors and clumsiness. Yet the common image today of von Neumann is of the unparalleled computing genius — flawless in his every action. And indeed, there can be no doubt of von Neumann's genius. His very ability to realize his human limitations put him head and shoulders above the average programmer today. Average people can be trained to accept their humanity — their inability to function like a machine — and to value it and work with others so as to keep it under the kind of control needed if programming is to be successful.”
