A Quote by Karl Popper

[The aim of science is] to explain what so far has taken to be an explicans, such as a law of nature. The task of empirical science constantly renews itself. We may go on forever, proceeding to explanations of a higher and higher universality.
Alternative explanations are always welcome in science, if they are better and explain more. Alternative explanations that explain nothing are not welcome... Note how science changed those beliefs when new data became available. Religions stick to the same ancient beliefs regardless of the data.
As accelerators reach higher and higher energies, we may need a new Standard Model, or, at least, today's may need to be modified, but that's the way science operates.
...neither is it possible to discover the more remote and deeper parts of any science, if you stand but upon the level of the same science, and ascend not to a higher science.
It is no valid objection that science as yet throws no light on the far higher problem of the essence or origin of life. Who can explain gravity? No one now objects to following out the results consequent on this unknown element of attraction.
To feed applied science by starving basic science is like economising on the foundations of a building so that it may be built higher. It is only a matter of time before the whole edifice crumbles.
There are three kinds of explanation in science: explanations which throw a light upon, or give a hint at a matter; explanations which do not explain anything; and explanations which obscure everything.
One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world. And it seems, and not without reason, that now is the really critical moment for natural science; for the brain, in its highest complexity-the human brain-which created and creates natural science, itself becomes the object of this science.
It doesn't matter how far you might rise. At some point you are bound to stumble because if you’re constantly doing what we do, raising the bar. If you're constantly pushing yourself higher, higher the law of averages not to mention the Myth of Icarus predicts that you will at some point fall. And when you do I want you to know this, remember this: there is no such thing as failure. Failure is just life trying to move us in another direction.
Mathematics, the non-empirical science par excellence . . . the science of sciences, delivering the key to those laws of nature and the universe which are concealed by appearances.
If you're constantly pushing yourself higher, higher, the law of averages - not to mention the myth of Icarus - predicts that you will at some point fall. And when you do, I want you to know this, remember this: There is no such thing as failure.
Being points beyond itself. Accustomed to think in terms of space, the expression "being points beyond itself" may be taken to denote a higher point in space. What is meant, however, is a higher category than being: the power of maintaining being.
Out of man's mind in free play comes the creation Science. It renews itself, like the generations, thanks to an activity which is the best game of homo ludens: science is in the strictest and best sense a glorious entertainment.
The task of evolutionary psychology is not to weigh in on human nature, a task better left to others. It is to add the satisfying kind of insight that only science can provide: to connect what we know about human nature with the rest of our knowledge of how the world works, and to explain the largest number of facts with the smallest number of assumptions.
As plants take hold, not for the sake of staying, but only that they may climb higher, so it is with men. By every part of our nature we clasp things above us, one after another, not for the sake of remaining where we take hold, but that we may go higher.
Gradually, ... the aspect of science as knowledge is being thrust into the background by the aspect of science as the power of manipulating nature. It is because science gives us the power of manipulating nature that it has more social importance than art. Science as the pursuit of truth is the equal, but not the superior, of art. Science as a technique, though it may have little intrinsic value, has a practical importance to which art cannot aspire.
Economics is a theoretical science and as such abstains from any judgement of value. It is not its task to tell people what ends they should aim at. It is a science of the means to be applied for attainment of ends chosen, not, to be sure, a science of the choosing of ends. Ultimate decisions, the valuations and the choosing of ends, are beyond the scope of any science. Science never tells a man how he should act; it merely shows how a man must act if he wants to attain definite ends.
