My Philosophy of sciences

If there is something that i like after sociology it is philosophy and especially of sciences and political. i like to read about how the sciences creates its own legitimation from philosophy. The science in the beginning it was only philosophy, sciences don't exist like we know it today, it was only dialogic, conversations between people who has many time to do anything they wanted which means commonly walks around the city and think, I mean somebody who had to work like a carpenter could not be a philosopher, beacuse he had to dedicate his life to do things with wood. The philosopher don't have common occupations they are mainly teachers, how did born the philosophers? I don't know the only sure thing is that philosophers came from laziness, from being hours looking at the water and says: the water is the very beginning of things, like said Tales from Mileto. Philosophy of sciences is ask to ourself and the other who came before us, what do we understand of science?, what is science, essentially?, the answers are very different it is connected with a subjet called Epistemology which tries to explain how is that we know. I say that there are different answers to the question of what is science. FIrst we have to ask to epistemologists, how do we know, what is that thing that we know? They says that the world is something that we built that means that reality is a paradox because the world would not be real if we don't exist if we don't build it so if humans don't exist then nothing exist but there are some others epistemologists who says that the world is real by itself so if we don't exist the world continues existing. By keeping this mind we can ask about science, what is science, is the knowledge of the world which exist when we build it accordingly to first case but the second case means that sciences are the knowledge of the world that exists by itself it's not our construction. So I can say i believe or i think the world is what i build as world.
