Sartre philosophized by constantly thinking against himself, unlike the circling Heidegger.

Evidence

Whereas Heidegger circled around his home territory, Sartre moved ever forwards, always working out new (often bizarre) responses to things, or finding ways of reconciling old ideas with fresh input. Heidegger intoned that one must think, but Sartre actually thought. Heidegger had his big Kehre — his ‘turn’ — but Sartre turned and turned and turned again. He was always thinking ‘against himself’, as he once said, and he followed Husserl’s phenomenological command by exploring whatever topic seemed most difficult at each moment. — Sarah Bakewell, At the Existentialist Café, 1015
