Evidence Quotes

“We have overwhelming evidence that available information plus analysis does not lead to knowledge. The management science team can properly analyse a situation and present recommendations to the manager, but no change occurs. The situation is so familiar to those of us who try to practice management science that I hardly need to describe the cases.”

“The first job of the historian and of the journalist is to find facts. Not the only job, perhaps not the most important, but the first. Facts are the cobblestones from which we build roads of analysis, mosaic tiles that we fit together to compose pictures of past and present. There will be disagreement about where the road leads and what reality or truth is revealed by the mosaic picture. The facts themselves must be checked against all the available evidence. But some are round and hard--and the most powerful leaders in the world can trip over them. So can writers, dissidents and saints.”

“The way in which I know Christianity is true is first and foremost is the basis of the witness of the Holy Spirit in my heart. And this gives me self-authenticating means of knowing Christianity is true wholly apart from the evidence. And therefore, even if in some historically contingent circumstances the evidence that I have available to me should turn against Christianity, I do not think that controverts the witness of the Holy Spirit.”

“To know whether you can trust a particular intuitive judgment, there are two questions you should ask: Is the environment in which the judgment is made sufficiently regular to enable predictions from the available evidence? The answer is yes for diagnosticians, no for stock pickers. Do the professionals have an adequate opportunity to learn the cues and the regularities? The answer here depends on the professionals' experience and on the quality and speed with which they discover their mistakes.”

“But what, after all, is faith? It is a state of mind that leads people to believe something - it doesn't matter what - in the total absence of supporting evidence. If there were good supporting evidence then faith would be superfluous, for the evidence would compel us to believe it anyway. It is this that makes the often-parroted claim that 'evolution itself is a matter of faith' so silly. People believe in evolution not because they arbitrarily want to believe it but because of overwhelming, publicly available evidence.”

“I think it's a very stark marker of what kind of president we have that, from all available evidence, Donald Trump has not read a book, as an adult. This is not someone who sits down in the evening to consider the latest bestseller, let alone Tolstoy - but who is very very active on this medium that requires no discipline and no attention and no empathy. It is all about retweeting praise of oneself or very quickly or poorly considered, ill-typed, misspelled diatribes against other people.”

“Human beings act in a great variety of irrational ways, but all of them seem to be capable, if given a fair chance, of making a reasonable choice in the light of available evidence. Democratic institutions can be made to work only if all concerned do their best to impart knowledge and to encourage rationality. But today, in the world's most powerful democracy, the politicians and the propagandists prefer to make nonsense of democratic procedures by appealing almost exclusively to the ignorance and irrationality of the electors.”

“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.”

“The amount of knowledge which we can justify from evidence directly available to us can never be large. The overwhelming proportion of our factual beliefs continue therefore to be held at second hand through trusting others, and in the great majority of cases our trust is placed in the authority of comparatively few people of widely acknowledged standing.”

“[Theory is] an explanation that has been confirmed to such a degree, by observation and experiment, that knowledgeable experts accept it as fact. That's what scientists mean when they talk about a theory: not a dreamy and unreliable speculation, but an explanatory statement that fits the evidence. They embrace such an explanation confidently but provisionally - taking it as their best available view of reality, at least unil some severely conflicting data or some better explanation might come along.”

“All scientific work is incomplete - whether it be observational or experimental. All scientific work is liable to be upset or modified by advancing knowledge. That does not confer upon us a freedom to ignore the knowledge we already have, to postpone action that it appears to demand at a given time. Who knows, asks Robert Browning, but the world may end tonight? True, but on available evidence most of us make ready to commute on the 8:30 next day.”

“One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.”

“Religion shows a pattern of heredity which I think is similar to genetic heredity. ... There are hundreds of different religious sects, and every religious person is loyal to just one of these. ... The overwhelming majority just happen to choose the one their parents belonged to. Not the sect that has the best evidence in its favour, the best miracles, the best moral code, the best cathedral, the best stained-glass, the best music when it comes to choosing from the smorgasbord of available religions, their potential virtues seem to count for nothing compared to the matter of heredity.”
