Here’s a somewhat different answer to the general question, inspired by a PM I just read, from Dan~.
Humans can be usefully defined as the animal that requires narrative. We simply cannot function effectively without narrative. Science gives us one general type of narrative, along with machinery and useful processes. Philosophy gives us a different type of narrative. This is not to say that there is never any science in philosophy nor philosophy in science.
But let’s not get too subtle so early in the game.
Let’s get to one of the main activities of philosophy - argument. That’s what philosophers do - they formulate arguments. Your basic deductive argument is what in the context of science is called a proof. Philosophers use “proofs” but they also use other types of arguments. It was philosophers who struggled to work out the rules of proofs, and while this struggle was going on, philosophy was being done. The generation of the method itself, that is, was done by philosophers.
Enough progress was made that scientists, once they got around to it, adopted this method for their own work. The scientific method was a gift from philosophy to science.
Now, philosophers use certain perversions of that method to accomplish all manner of idiotic stuff, because those perversions are of no use to scientists, by and large. Although software writers do occasionally use a few of these methods. That’s because software writers are sometimes trying to mimic and accommodate the way we think and are not in search of much of anything else.
But the arsenal of arguments possessed by philosophers is larger yet. Philosophers never tire of trying to find new ways of arguing, although the number of ways must surely be limited.
Much of the progress gained in science is due to the fact that scientists can either believe in God or not and their results may not be affected by their belief, although often enough, those results are affected. Philosopher don’t have that luxury. Religious beliefs make a lot of difference in philosophy. Metaphysics makes a difference.
Metaphysics requires and generates a very different narrative in philosophy than a non-metaphysical view does.
In short - scientists can be blind to the larger questions and still be good scientists. Not always, but it’s possible. Not so for philosophers. Scientists are seeking a more narrowly-focused narrative. Philosophers don’t enjoy that restriction. This has produced a lot of lousy philosophy, but it also allows philosophers to throw a lot of stuff against the wall, just to see what sticks. Which is why there has been progress in philosophy.
That progress is not even recognised by many philosophers, but it’s there. Most philosophers are idiots, because most people are idiots. Most people are blinded by desire, by desires that don’t lead anywhere. Most philosophers are politicians. They want a nice, comfy group to belong to, even if that group doesn’t really exist. You often have to find the philosophy hiding in what they write.
So it kind of depends on what you call philosophy. Hobbes had a few grains of usefulness in his insane royalist babblings. Mostly, he wasn’t a philosopher at all. His argument was garbage and his goals were stupid. Just an example. But you could hardly take his work as an example of philosophy in order to find the answers to your questions.
That’s why it’s difficult to answer them.
