It would be useless to turn one’s back on the past in order simply to concentrate on the future. It is a dangerous illusion to believe that such a thing is even possible. The opposition of future to past or past to future is absurd. The future brings us nothing, gives us nothing; it is we who in order to build it have to give it everything, our very life. But to be able to give, one has to possess; and we possess no other life, no other living sap, than the treasures stored up from the past and digested, assimilated, and created afresh by us. Of all the human soul’s needs, none is more vital than this one of the past…
The past once destroyed never returns. The destruction of the past is perhaps the greatest of all crimes. Today the preservation of what little of it remains ought to become almost an obsession. We must put an end to the terrible uprootedness which European colonial methods always produce, even under their least cruel aspects. We must abstain, once victory  is ours, from punishing the conquered enemy by uprooting him still further; seeing that it is neither possible nor desirable to exterminate him, to aggravate his lunacy would be to show oneself more of a lunatic than he. We must also keep, above all, well to the fore any political, legal, or technical innovations likely to have social repercussions, some arrangement whereby human beings may once more be able to recover their roots.
