Consider also the revolutionary utopians, who typically achieve only destruction and stagnation. Though they are blind optimists, what defines them as utopians is their pessimism that their supposed utopia, or their violent proposals for achieving and entrenching it, could ever be improved upon. Additionally,David Deutsch David Deutsch Sayings By David Deutsch: Consider also the revolutionary utopians, who typically achieve only destruction and stagnation. Though they are

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 David Deutsch Sayings By David Deutsch: Humans may or may not have cosmic significance, and if they do, it will be
Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them.David Deutsch David Deutsch Sayings By David Deutsch: Science is objective. And in my view we cannot take any experimental results seriously except
Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.David Deutsch David Deutsch Sayings By David Deutsch: Where we have good, testable explanations, they then have to be tested, and we drop
Sparta has no philosophers. That's because the job of a philosopher is to understand things better, which is a form of change, so they don't want it. Another difference: they don't honour living poets, only dead ones. Why? Because dead poets don't write anything new, but live ones do. A third difference: their education system is insanely harsh; ours is famously lax. Why? Because they don't want their kids to dare to question anything, so that they won't ever think of changing anything. HowDavid Deutsch David Deutsch Sayings By David Deutsch: Sparta has no philosophers. That's because the job of a philosopher is to understand things
The quantum theory of parallel universes is not the problem, it is the solution. It is not some troublesome, optional interpretation emerging from arcane theoretical considerations. It is the explanation, the only one that is tenable, of a remarkable and counter-intuitive reality.David Deutsch David Deutsch Sayings By David Deutsch: The quantum theory of parallel universes is not the problem, it is the solution. It
The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.David Deutsch David Deutsch Sayings By David Deutsch: The most important application of quantum computing in the future is likely to be a
The whole [scientific] process resembles biological evolution. 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.David Deutsch David Deutsch Sayings By David Deutsch: The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and
Copenhagen interpretation Niels Bohr's combination of instrumentalism, anthropocentrism and studied ambiguity, used to avoid understanding quantum theory as being about reality.David Deutsch David Deutsch Sayings By David Deutsch: Copenhagen interpretation Niels Bohr's combination of instrumentalism, anthropocentrism and studied ambiguity, used to avoid understanding
If it turns out that all this time we have merely been studying the programming of a cosmic planetarium, then that would merely mean that we have been studying a smaller portion of reality than we thought. So what? Such things have happened many times in the history of science, as our horizons have expanded beyond the Earth to include the solar system, our Galaxy, other galaxies, clusters of galaxies and so on, and, of course, parallel universes.David Deutsch David Deutsch Sayings By David Deutsch: If it turns out that all this time we have merely been studying the programming
The Enlightenment (The beginning of) a way of pursuing knowledge with a tradition of criticism and seeking good explanations instead of reliance on authority.David Deutsch David Deutsch Sayings By David Deutsch: The Enlightenment (The beginning of) a way of pursuing knowledge with a tradition of criticism

Steve Grand is the creator of what I think is the nearest approach to artificial life so far, and his first book, Creation: Life and How to Make It, is as interesting as you would expect. But he illuminates more than just the properties of life: his originality extends to matter itself and the very nature of reality. Not since David Deutsch's The Fabric of Reality have I encountered such a compelling invitation to think everything out afresh, from the bottom up.Richard Dawkins David Deutsch Sayings By Richard Dawkins: Steve Grand is the creator of what I think is the nearest approach to artificial
I don't think it would be a good idea for scientists to have more political power. Scientists as a group are more inclined to try to derive an ought from an is, than the population at large.David Deutsch David Deutsch Sayings By David Deutsch: I don't think it would be a good idea for scientists to have more political
I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.David Deutsch David Deutsch Sayings By David Deutsch: I myself believe that there will one day be time travel because when we find
mechanical reinterpretations of human affairs not only lack explanatory power, they are morally wrong as well, for in effect they deny the humanity of the participants, casting them and their ideas merely as side effects of the landscape. DiamondDavid Deutsch David Deutsch Sayings By David Deutsch: mechanical reinterpretations of human affairs not only lack explanatory power, they are morally wrong as

Trying to rely on the sheer good luck of avoiding bad outcomes indefinitely would simply guarantee that we would eventually fail without the means of recovering.David Deutsch David Deutsch Sayings By David Deutsch: Trying to rely on the sheer good luck of avoiding bad outcomes indefinitely would simply
The theory that the biosphere was created without evolution, a few thousand years ago, is ruled out by overwhelming scientific evidence. To claim that there are 'alternative (always better) Biblical explanations of the same data', which make creationism a reasonable alternative to our best theories of biology and physics, is appalling intellectual dishonesty.David Deutsch David Deutsch Sayings By David Deutsch: The theory that the biosphere was created without evolution, a few thousand years ago, is
Because we are universal explainers, we are not simply obeying our genes. ForDavid Deutsch David Deutsch Sayings By David Deutsch: Because we are universal explainers, we are not simply obeying our genes. For
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. Unfortunately, the term 'the Enlightenment' is used by historians and philosophers to denote a variety of different trends, some of them violently opposed to each other. What I mean by it will emerge here as we go along. It is one of several aspects of 'the beginning of infinity', and is a theme of this book. 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.David Deutsch David Deutsch Sayings By David Deutsch: The scientific revolution was part of a wider intellectual revolution, the Enlightenment, which also brought
Yet, over time, the conclusions that science has drawn have become ever truer to reality.David Deutsch David Deutsch Sayings By David Deutsch: Yet, over time, the conclusions that science has drawn have become ever truer to reality.
The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.David Deutsch David Deutsch Sayings By David Deutsch: The overwhelming majority of theories are rejected because they contain bad explanations, not because they
If two programs respond in the same way to every possible action by the user, then they render the same environment; if they would respond perceptibly differently to even one possible action, they render different environments.David Deutsch David Deutsch Sayings By David Deutsch: If two programs respond in the same way to every possible action by the user,

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.David Deutsch David Deutsch Sayings By David Deutsch: Because pessimism needs to counter that argument in order to be at all persuasive, a
The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations.David Deutsch David Deutsch Sayings By David Deutsch: The truly privileged theories are not the ones referring to any particular scale of size
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. But we should feel more than sympathy for those people. We should take it personally. For if any of those earlier experiments in optimism had succeeded, our species would be exploring the stars by now, and you and I would be immortal.David Deutsch David Deutsch Sayings By David Deutsch: Like every other destruction of optimism, whether in a whole civilisation or in a single
If you reject the infinite, you are stuck with the finite, and the finite is parochial ... the best explanation of anything eventually involves universality, and therefore infinity. The reach of explanations cannot be limited by fiat.David Deutsch David Deutsch Sayings By David Deutsch: If you reject the infinite, you are stuck with the finite, and the finite is
It is a mistake to conceive of choice and decision-making as a process of selecting from existing options according to a fixed formula. That omits the most important element of decision-making, namely the creation of new options. GoodDavid Deutsch David Deutsch Sayings By David Deutsch: It is a mistake to conceive of choice and decision-making as a process of selecting
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.David Deutsch David Deutsch Sayings By David Deutsch: The brain is the only kind of object capable of understanding that the cosmos is
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.David Deutsch David Deutsch Sayings By David Deutsch: To me quantum computation is a new and deeper and better way to understand the
This inductively justifies the conclusion that induction cannot justify any conclusions.David Deutsch David Deutsch Sayings By David Deutsch: This inductively justifies the conclusion that induction cannot justify any conclusions.
No precautions, and no precautionary principle, can avoid problems that we do not yet foresee. We need a stance of problem-fixing, not just problem-avoidance.David Deutsch David Deutsch Sayings By David Deutsch: No precautions, and no precautionary principle, can avoid problems that we do not yet foresee.
Bad philosophy before the Enlightenment was typically of the because-I-say-so variety. When the Enlightenment liberated philosophy and science, they both began to make progress, and increasingly there was good philosophy. But, paradoxically, bad philosophy became worse.David Deutsch David Deutsch Sayings By David Deutsch: Bad philosophy before the Enlightenment was typically of the because-I-say-so variety. When the Enlightenment liberated
The most general way of stating the central assertion of the neo-Darwinian theory of evolution is that a population of replicators subject to variation (for instance by imperfect copying) will be taken over by those variants that are better than their rivals at causing themselves to be replicated. ThisDavid Deutsch David Deutsch Sayings By David Deutsch: The most general way of stating the central assertion of the neo-Darwinian theory of evolution

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.David Deutsch David Deutsch Sayings By David Deutsch: Base metals can be transmuted into gold by stars, and by intelligent beings who understand
So the professor takes the student's point seriously, and responds with a concise but adequate argument in defence of the disputed equation. The professor tries hard to show no sign of being irritated by criticism from so lowly a source. Most of the questions from the floor will have the form of criticisms which, if valid, would diminish or destroy the professor's life's work. But bringing vigorous and diverse criticism to bear on accepted truths is one of the very purposes of the seminar. Everyone takes it for granted that the truth is not obvious, and that the obvious need not be true; that ideas are to be accepted or rejected according to their content and not their origin; that the greatest minds can easily make mistakes; and that the most trivial-seeming objection may be the key to a great new discovery.David Deutsch David Deutsch Sayings By David Deutsch: So the professor takes the student's point seriously, and responds with a concise but adequate
Discovering a new explanation is inherently an act of creativity.David Deutsch David Deutsch Sayings By David Deutsch: Discovering a new explanation is inherently an act of creativity.
Whenever a wide range of variant theories can account equally well for the phenomenon they are trying to explain, there is no reason to prefer one of them over the others, so advocating a particular one in preference to the others is irrational.David Deutsch David Deutsch Sayings By David Deutsch: Whenever a wide range of variant theories can account equally well for the phenomenon they
From the least parochial perspectives available to us, people are the most significant entities in the cosmic scheme of things. They are not 'supported' by their environments, but support themselves by creating knowledge. Once they have suitable knowledge (essentially, the knowledge of the Enlightenment), they are capable of sparking unlimited further progress.David Deutsch David Deutsch Sayings By David Deutsch: From the least parochial perspectives available to us, people are the most significant entities in

Time travel may be achieved one day, or it may not. 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.David Deutsch David Deutsch Sayings By David Deutsch: Time travel may be achieved one day, or it may not. But if it is,
Perhaps a more practical way of stressing the same truth would be to frame the growth of knowledge (all knowledge, not only scientific) as a continual transition from problems to better problems, rather than from problems to solutions or from theories to better theories. ThisDavid Deutsch David Deutsch Sayings By David Deutsch: Perhaps a more practical way of stressing the same truth would be to frame the
