I asked a question earlier about how the Genealogy of Morals by Nietzsche had held out in terms how accurate his philosophy was, now that we know more about the emergence of the human animal. The question was put on hold because the commenter said that philosophers often do "arm-chair myths about how society arrived" and the checking of those myths isn't within the scope of philosophy, I provide a link to my question below, however, I'd like to ask a more general question:
Is philosophy simply conjuring up theories, ideas, myths, stories etc. in order to answer questions without much concern for the evidence that may help improve the answers to such questions. I have always thought philosophy was a form of study where many different disciplines and ideas came together to provide answers under different interpretations, thereby increasing the stock of knowledge, and if this is true then shouldn't philosophers keep a finger on the pulse of other disciplines like science and even religion. I am wrong to think of philosophy in this way? Do philosophers only look for some internal logic in their work and care not if it turns out to be consistent with observational data? Thank you and I apologize if this question too is misguided, I am new to philosophy and perhaps I have asked another silly question.
