Are you asserting that philosophy is useless and doesn't work whatsoever?
I don't think so. We have kind of split things up into sections like philosophy and science but in reality there is only one Pursuit of Knowledge.
And it's kind of sensible that if we find something that works, that it should be declared true. This sounds obvious but people didn't always believe it. They preferred treating 'Humors' in the human body rather than looking at the body-count-evidence, or doing rain dances without even evaluating whether they work. So the great step forward has been to match what works with what we believe - broadly, science.
And ever since then the sub-branch of knowledge that is philosophy has become more and more useless by comparison to science, as science has just exploded.
Personally I think that compared to science, philosophy is virtually useless. Not through it's own fault but simply by being eclipsed by the huge success of science. Also I think that, just as there was great resistance to empirical methods informing our knowledge in the past - like medicine - there is still great resistance to science informing philosophy today.
Ultimately, though, that resistance will crumble. What works will win out.
Formerly it has been presumed all knowledge is equally available to all people. The reason it has been this way is that those entering a body of knowledge feel that it is natural to them, but to see what the other groups are doing requires knowledge about knowledge, which is to say about the mind itself, and such a science has not appeared.
Philosophy has indeed been useless, but not to the individuals engaging in it. The trouble of philosophy is that it is lost in false abstractions, the cats chasing their own tails, as it were. These are people who are just gaining the ability to look at thoughts themselves, but without the ability to induce major changes in thinking, or to begin purifying the mind. It means their words don’t stand for much, concepts about concepts being empty.
There is a science above philosophy, dealing in metaphysical and existential realities, but this science can only be entered by those with deep experience of their own souls, perhaps gained in ages past. The statements and logic of this higher science seem like gibberish to those whose only experience of the senses in this body. For now it may be important to notice that as most college students steer a wide path away from philosophy, they say it just doesn’t interest them. They haven’t noticed that it is impossible for them.
