de Norpois knew. How could he fail to know it seeing that he was a friend of all the Ministers? Naturally, Bloch thought that the truth in politics could be approximately reconstructed by the most luminous minds, but he imagined, like the man in the street, that it resided permanently, beyond the reach of argument and in a material form, in the secret files of the President of the Republic and the Prime Minister, who imparted it to their Cabinet. Now, even when a political truth does take the form of written documents, it is seldom that these have any more value than a radiographic plate on which the layman imagines that the patient’s disease is inscribed in so many words, when, as a matter of fact, the plate furnishes simply one piece of material for study, to be combined with a number of others, which the doctor’s reasoning powers will take into consideration as a whole and upon them found his diagnosis. So, too, the truth in politics, when one goes to well-informed men and imagines that one is about to grasp it, eludes one.
