Yes; except they never really parted at a fundamental level.
If you look at the history of a lot of eminent philosophers
they were often exceedingly capable in areas other than philosophy
- for example Russell and Quine in mathematics - and they
gravitated to the foundations of these disciplines. Carnap
studied physics. The hallmark is that they did not take for
granted the foundations of the disciplines they studied.
This is very much what I wanted to convey. That philosophy
is by its nature, questioning, and potentially revolutionary.
This is often masked by academic philosophy which is
conducted by people climbing the tenure ladder.
