Philosophy has been dealing with many of these questions for thousands of years. What progress do we see? What has been resolved?Well, no, it's not the best method. It's a method that works best when investigating the physicality of existence. But there are other methods that work better at investigating other aspects of our experience of existence. And failing to recognize this is exactly the danger of becoming a 'true believer". In this case, in scientism.
Science has no eclipsed those other methods of understanding existence. In fact, or glaring abuse of scientific knowledge just serves to show us how insdiquate science alone is in term of providing us real understanding. And your wildly grandiose assessment of it is called 'scientism'.
Science of not the enemy of anything. Neither is religion. But scientism is a real problem. Just like religion is when it becomes a fettish.
Unless we can objectively verify a claim with repeatable, empirical testing, how is it any more than speculation?
What tools does philosophy use to verify claims?
