Existentialist philosophy values active engaged form over abstract speculation

Evidence

Both Sartre and Beauvoir emphasized philosophizing as action over abstract and sterile systematic speculations. Both preferred vita activa rather than vita contemplativa and thought that existentialist philosophy had to take on a form that was conducive to action in order to become relevant to the concrete lives of persons who conceived it. — Christine Daigle, Jacob Golomb (eds.), Beauvoir and Sartre, 38
