What is to be done, at present? The question is on everybody’s lips and, in a certain way, it is the question people today always have lying in wait for any passing philosopher. Not: What is to be thought? But indeed: What is to be done? The question is on everybody’s lips (including the philosopher’s), but withheld, barely uttered, for we do not know if we still have the right, or whether we have the means, to raise it. Perhaps, we think more or less discreetly to ourselves, perhaps the uncertainty of ‘what is to be done?’ is today so great, so fluctuating, so indeterminate, that we do not need even to do this: raise the question.
