It is impossible not to recall Merleau-Ponty’s lesson and what was for him was the essential, philosophical task. Never consent to be completely comfortable with your own certainties. Never let them sleep, but never believe either that a new fact will be enough to reverse them. Never imagine that one can change them like arbitrary axioms. Remember that, in order to give them an indispensable mobility, one must see far, but also close-up and right around oneself. One must clearly feel that everything perceived is only evident when surrounded by a familiar and poorly known horizon, that each certitude is only sure because of the support offered by unexplored ground. The most fragile instant has roots. There is here a whole ethics of tireless evidence that does not exclude a rigorous economy of the True and the False; but is not reduced to it, either.
