"It is the function of the philosopher, the care and passion of the philosopher, to protect to the utmost the possible, he tends the possible like a small child, he broods over it like a newborn babe, he is the guardian of the seed. The philosopher is the shepherd who tends the mixed flock of possibles on the highlands, heavy ewes and shuddering bulls, the philosopher is a gardener, he crosses and multiplies varieties, he safeguards the vastness of the old-growth forest, he is on the watch for the inclemency of the elements, a carrier of new seasons of history and of duration, fat cows and lean cows, the philosopher is the shepherd of multiplicities.
The philosopher... protects neither essence nor truth. It is the function of the politician to be right and rational, it is the function of the scientist to be right and rational; there are plenty of functionaries of the truth as it is, without adding more. The philosopher does not wrap himself up in truth as in breastplate or shield, he does not sing nor does he pray to allay nocturnal fears, he wants to let the possibles roam free. Hope is in these margins, and freedom."
Michel Serres - "Genesis"
