A Quote by Karl Popper
I think that we shall have to get accustomed to the idea that we must not look upon science as a 'body of knowledge,' but rather as a system of hypotheses; that is to say, as a system of guesses or anticipations which in principle cannot be justified, but with which we work as long as they stand up to tests, and of which we are never justified in saying that we know they are 'true' or 'more or less certain' or even 'probable.'

Science is not a system of certain, or -established, statements; nor is it a system which steadily advances towards a state of finality... And our guesses are guided by the unscientific, the metaphysical (though biologically explicable) faith in laws, in regularities which we can uncover-discover. Like Bacon, we might describe our own contemporary science-'the method of reasoning which men now ordinarily apply to nature'-as consisting of 'anticipations, rash and premature' and as 'prejudices'.
Is evolution a theory, a system, or a hypothesis? It is much more it is a general postulate to which all theories, all hypotheses, all systems must henceforward bow and which they must satisfy in order to be thinkable and true. Evolution is a light which illuminates all facts, a trajectory which all lines of thought must follow this is what evolution is.
Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.
In real science a hypothesis can never be proved true...A science which confines itself to correlating phenomena can never learn anything about the reality underlying the phenomena, while a science which goes further than this and introduces hypotheses about reality, can never acquire certain knowledge of a positive kind about reality; in whatever way we proceed, this is forever denied us.
Convictions following the admission into evidence of confessions which are involuntary, i.e., the product of coercion, either physical or psychological, cannot stand. This is so not because such confessions are unlikely to be true but because the methods used to extract them offend an underlying principle in the enforcement of our criminal law: that ours is an accusatorial, and not an inquisitorial, system - a system in which the State must establish guilt by evidence independently and freely secured, and may not, by coercion, prove its charges against an accused out of his own mouth.
No political party is justified to continue in existence unless it clearly states the principles which it advocates, the platform upon which its candidates stand, and then with integrity, when and if elected, carry out those principles and live up to that platform. Except that be the case, we as Latter-day Saints should not align ourselves to any party, because we do not have the basis upon which we can make an intelligent decision. We must know what they stand for before we can favor them with our vote.
In comparison to the U.S. health care system, the German system is clearly better, because the German health care system works for everyone who needs care, ... costs little money, and it's not a system about which you have to worry all the time. I think that for us the risk is that the private system undermines the solidarity principle. If that is fixed and we concentrate a little bit on better competition and more research, I think the German health care system is a nice third way between a for-profit system on the one hand and, let's say, a single-payer system on the other hand.
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
Well, there is a contradiction in a sense. If you're making commercials which sell products which are unhealthy or which are unnecessary, I think that you are part of a system - I am part of a system which encourages people to buy things and do things which are not to their best interest. And to that extent you could say it was contradictory.
We are unconscious of most of our body's processes, thank goodness, because we'd screw it up if we weren't. The human body is so complex, with so many parts...a system which is far more complex than we can fully imagine. The idea that we are consciously care-taking such a large and mysterious system is ludicrous.
Monopolies are not justified by theory; they should be permitted only when justified by facts. If there is no solid basis for extending a certain monopoly protection, then we should not extend that protection. This does not mean that every copyright must prove its value initially. That would be a far too cumbersome system of control. But it does mean that every system or category of copyright or patent should prove its worth. Before the monopoly should be permitted, there must be reason to believe it will do some good -- for society, and not just for monopoly holders.
In the United States at present the 'culture wars' of the last thirty years have now produced a horrid stand-off which compels you all into a binary either/or with all kinds of spin-offs. This is deeply unhealthy. The trouble is that the way the system is set up in order to get in and try to change it you have to be (a) a millionaire, (b) someone who can work inside the system long-term, (c) someone prepared to make deals and compromises... Which does rule out the vast majority of committed Christians.
Science is not a body of knowledge nor a system of belief; it is just a term which describes humankind’s incremental acquisition of understanding through observation. Science is awesome.
The fact would seem to be, if in my situation one may speak of facts, not only that I shall have to speak of things of which I cannot speak, but also, which is even more interesting, but also that I, which is if possible even more interesting, that I shall have to, I forget, no matter. And at the same time I am obliged to speak. I shall never be silent. Never.
I say that our system of tests and grades, as it now exists, is one source of the low yield of great men from our universities. The marking system is a traumatic experience from which most students emerge with a deep determination never to get into a situation where they can be marked again. They just won't ever again take a chance.
In a corporate context, companies have to try very hard to oppose the enticements of conventional wisdom. They must aim for the leaps, which means that companies have to do more than simply manage their knowledge, which is composed of the insights and understandings they already know. They also have to manage the knowledge-generation process. It's not just about, "Oh, we're going to create a data warehouse and we are going to invent a computerized filing system to get at all the stuff we know."
