I actually have. And I have read a LOT and I mean a LOT of philosophy.

All the great philosophers of history to begin with. I have read all their most famous works. And I have enjoyed them. I think they are great read. But great LITERATURE read. Not scientific reads.

I still think they are not science, as they do not describe nature. They just give opinions on several matters. And the few who dared to make any predictions about the future failed miserably.

If they are science they should be able to do predictions about nature. To propose experiments that are proven true. They should be falsable if proven untrue.

And just for the record, I have also read the full Bible. It's also a great piece of literature, but it obviously doesn't depict the reality of nature as a product of the scientific method.

And just to make a point, just because some old guy you got impressed by told you something is true, doesn't make it true. Take this last sentence as you wish.
