The proximity to cogito ergo sumus springs to mind, but the point is not that we are when somebody is thinking – what is needed is action in the form of rebellion because rebellion with the purpose of bringing about change needs collective action.

While rebellion rarely spreads to the quantitative majority of people, it can still provoke, or indeed bring about, radical change. Unfortunately though, rebellion does not per se bring about empathic and emancipatory action, but also facilitates dangerous, authoritarian and petit-bourgeois societal tendencies. The existentialist Albert Camus, however, did not really have a problem with this.
