But, in any case, those are mistakes.
Welcome back. The universe is not there to overwhelm us; it is our home, and our resource. The theory that the biosphere was created without evolution, a few thousand years ago, is ruled out by overwhelming scientific evidence. But the god explained to me why that must be so, starting with the fallibility of the human mind and the unreliability of sensory experience.”, “The scientific revolution was part of a wider intellectual revolution, the Enlightenment, which also brought progress in other fields, especially moral and political philosophy, and in the institutions of society. We should take it personally. Share David Deutsch quotations about universe, reality and physics. Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book. Base metals can be transmuted into gold by stars, and by intelligent beings who understand the processes that power stars, but by nothing else in the universe. #May #Schemes #Cosmic “If you can’t program it, you haven’t understood it.”-- David Deutsch . To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole. It is not some troublesome, optional interpretation emerging from arcane theoretical considerations. If we can't program it, we can't understand it. Share with your friends. Consider”, “objective knowledge is indeed possible: it comes from within! What computers can or cannot compute is determined by the laws of physics alone, and not by pure mathematics.”, “It follows that humans, people and knowledge are not only objectively significant: they are by far the most significant phenomena in nature – the only ones whose behaviour cannot be understood without understanding everything of fundamental importance.”, “It is a mistake to conceive of choice and decision-making as a process of selecting from existing, “Although, through the vagaries of international politics, Athens became independent and democratic again soon afterwards, and continued for several generations to produce art, literature and philosophy, it was never again host to rapid, open-ended progress. To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole. “The Fabric of Reality”, p.13, Penguin UK, David Deutsch (2011). ― David Deutsch, The Beginning of Infinity: Explanations That Transform the World "The Father of Quantum Computing". Its other name is death.”, “All fiction that does not violate the laws of physics is fact.”, “As the physicist Stephen Hawking put it, humans are ‘just a chemical scum on the surface of a typical planet that’s in orbit round a typical star on the outskirts of a typical galaxy’. 2004. Or a herd of cows. But the Principle says that all such values are themselves anthropocentric: they explain only the behaviour of the scum, which is itself insignificant.”, “Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.”, “Base metals can be transmuted into gold by stars, and by intelligent beings who understand the processes that power stars, but by nothing else in the universe.”, “Like an explosive awaiting a spark, unimaginably numerous environments in the universe are waiting out there, for aeons on end, doing nothing at all or blindly generating evidence and storing it up or pouring it out into space. Other people are relieved to feel insignificant, which is even worse.
"The Fabric of Reality". A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche. Our best theories are not only truer than common sense, they make more sense than common sense.
Discovering a new explanation is inherently an act of creativity.
Quotations by David Deutsch, Scientist, Born 1953. Other people are relieved to feel insignificant, which is even worse. I chop and change between what is called 'work' and what is called 'recreation.' I guess that its optimism was gone.”, “We never know any data before interpreting it through theories. October 3, 2012. Science is objective. “The Fabric of Reality”, p.6, Penguin UK. The universe is not there to … Is the human race a universal constructor? We need a stance of problem-fixing, not just problem-avoidance. The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests. The brain is the only kind of object capable of understanding that the cosmos is even there, or why there are infinitely many prime numbers, or that apples fall because of the curvature of space-time, or that obeying its own inborn instincts can be morally wrong, or that it itself exists. “Some people become depressed at the scale of the universe, because it makes them feel insignificant. Find them all in one place, ordered by importance, study them and and post them on your Twitter account (page 1) The reach of explanations cannot be limited by fiat. But we should feel more than sympathy for those people. David Deutsch (2011). It is possible to build a virtual-reality generator whose repertoire includes every possible environment. Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things. Strategies to prevent foreseeable disasters are bound to fail eventually, and cannot even address the unforeseeable. #Stars #Intelligent #Gold “Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things.”-- David Deutsch . It is possible to build a virtual-reality generator whose repertoire includes every possible environment. Error-correction is the beginning of infinity.”, “Because we are universal explainers, we are not simply obeying our genes. Almost any of them would, if the right knowledge ever reached it, instantly and irrevocably burst into a radically different type of physical activity: intense knowledge-creation, displaying all the various kinds of complexity, universality and reach that are inherent in the laws of nature, and transforming that environment from what is typical today into what could become typical in the future. This is to miss the point of it. I don't think it would be a good idea for scientists to have more political power. But one thing that all conceptions of the Enlightenment agree on is that it was a rebellion, and specifically a rebellion against authority in regard to knowledge.”, “Because pessimism needs to counter that argument in order to be at all persuasive, a recurring theme in pessimistic theories throughout history has been that an exceptionally dangerous moment is imminent.”, The Beginning of Infinity: Explanations That Transform the World, The Fabric of Reality: The Science of Parallel Universes--and Its Implications. Computers are physical objects, and computations are physical processes. Such ideas do not create themselves, nor can they be mechanically derived from anything: they have to be guessed – after which they can be criticized and tested.”, “Whenever we observe anything – a scientific instrument or a galaxy or a human being – what we are actually seeing is a single-universe perspective on a larger object that extends some way into other universes. Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow. David Deutsch (2011). 1. But, in any case, those are mistakes. I never have been.
December 1, 2011. For”, “The theory of computation has traditionally been studied almost entirely in the abstract, as a topic in pure mathematics. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche.”, “Like every other destruction of optimism, whether in a whole civilisation or in a single individual, these must have been unspeakable catastrophes for those who had dared to expect progress. Scientists as a group are more inclined to try to derive an ought from an is, than the population at large. Just a moment while we sign you in to your Goodreads account. We interpret those differences, correctly, as evidence that the universe changes with time. All observations are, as Popper put it, theory-laden,* and hence fallible, as all our theories are. "Feeling insignificant because the universe is large has..." “The Fabric of Reality”, p.31, Penguin UK, There is a mistake in the text of this quote. And in my view we cannot take any experimental results seriously except in the light of good explanations of them. Improve yourself, find your inspiration, share with friends. Book by David Deutsch. This is the cosmic significance of explanatory knowledge – and hence of people, whom I shall henceforward define as entities that can create explanatory knowledge.”, “Good political institutions are those that make it as easy as possible to detect whether a ruler or policy is a mistake, and to remove rulers or policies without violence when they are.”, “Without error-correction all information processing, and hence all knowledge-creation, is necessarily bounded. It is the explanation - the only one that is tenable - of a remarkable and counter-intuitive reality. I only play tennis with people I find interesting. Or a herd of cows. No precautions, and no precautionary principle, can avoid problems that we do not yet foresee.
