What is the difference between science and philosophy?

Science, we have noted, uses concepts of generality with precision while philosophy uses concepts of generality without precision.

There is a jocular saying that the philosopher knows less and less about more and more until he knows nothing about everything, while the scientist knows more and more about less and less until he knows everything about nothing.

We can see with our own eyes that the core of the material world is found in some formula - which are nothing but small black signs on white paper - of Newton, Einstein, and others, and that from these symbols arose the technological world of today and its nuclear power. The whole development began with Galileo, in whose mind the fundamental transformation of which we have spoken took place, and Aristotelian concepts became symbols. It is thus beyond doubt that the difference between philosophy and science is defined by the difference between abstractions from the commonsense world and constructions of ideal relations applicable to this world. It is equally beyond doubt that the world will not be morally efficient unless the same transition takes place in moral philosophy.

What is the difference between science and philosophy?

Now the specialist, you might say, is the man who knows all the answers but does not understand the question. And the philosopher is the one who asks the questions. And since he is a specialist in asking questions, of course he has a hard time to answer. Another definition of a philosopher is, "he is the one who is doing away with himself all the time." That means that since he pioneers, you might say, asking the questions in the most general and unknown subjects, when he succeeds and gets an answer, they call him a scientists and that's the end of philosophy. So the philosopher is always the incipient scientist, or frustrated scientist, and the successful philosopher is the good scientist.
