Is philosophy a load of navel gazing pompous pointless nonsense?
For the most part, yes.
The few contributions we have from philosophy (logic, etc.) could just as easily have come from other fields as needed.
To scientists, the majority of philosophy now seems to be, "But you have to pay attention to us! We were here first! (Whimper. Snivel.)"
Just look at post-modernism and related nonsense for examples of modern philosophy.
No wonder most scientists couldn't care less.
(Flame suit on, but only set to moderate.)
