You apparently dont understand the purpose of philosophy. Philosophy is used when there is no possible or no conceived way to test a theory. Say you are given a box, this box cannot be opened and you can't see through it, but you can shake it, hit it , move it, weigh it, whatever your "hard science" allows you to do and your task that you put upon yourself is to find out what is in that box. Now, seeing as you have no empirical means of uncovering the contents of that box, we use what we have to chip at it or figure out the contents, but all those theories we come up with are "Philosophies" because at the end of the day, we have no insight as to what really is in that box and what we do come with is nothing more than speculation.
Here's a practical example, in ancient Greek times, there lived a philosopher named Aristotle (i do believe it was him, correct me if i'm wrong) who postulated a theory that matter can always be cut in half, it's size had nothing to do with it. It didn't matter how small the piece got, it could always be cut in half, that we would never reach the smallest piece. He also theorized that matter was comprised of 5 elements wind, earth, fire, water and the aether. Logically these theories are perfectly sound, i mean, so long as matter is there i can always split it, and all we see for the most part are variations of wind, earth, air and water, the differences like metal, or things like that can be determined by tints of aether and other elements or something similar. Even if we know those theories aren't right, they had no way to prove it or disprove it, but it did make sense, so it's all good.
Fast forward to today and we do have the technology to disprove it. however, the only reason we ever thought of trying to prove or disprove it, was because there was a philosophy that existed for it. We can't run an experiment without thinking of it first, that is where philosophy comes in. It is a method of exploring the possibilities when we do not have the physical means to verify it.
But let's look back, we'll take 4 elements originally thought of (disregarding aether) we have wind, earth, fire and water. hmm sounds like something that we have currently proved, no? let's try changing the names a little; gas, solid, energy, liquid... hot damn, they look very similar don't they? That is the true nature of science, you create a "philosophy" and then you go about trying to disprove that philosophy until you cannot doubt it anymore. Maybe your results are completely unrelated to your intentions, like earlier in this paragraph, what they thought to be elements was more similar to the states of matter. it was still scientifically relevant, but they didnt view it with the eyes we have today (metaphorically speaking) so they had no idea they were in the wrong.
After that brief history, ill stop here. there is so much more i can cover regarding this topic, but i already make a big ol' block o' text. if prompted for more "philosophy" i will be happy to reply
