“Cimourdain knew everything and nothing. He knew everything about science, and nothing at all about life. Hence his inflexibility.”

Part 2, Book 1, Ch. 2
Ninety-Three (1874)
Context: Cimourdain was one of those men who have a voice within them, and who listen to it. Such men seem absent-minded; they are not; they are all attention.
Cimourdain knew everything and nothing. He knew everything about science, and nothing at all about life. Hence his inflexibility. His eyes were bandaged like Homer's Themis. He had the blind certainty of the arrow, which sees only the mark and flies to it. In a revolution, nothing is more terrible than a straight line. Cimourdain went straight ahead, as sure as fate.
Cimourdain believed that, in social geneses, the extreme point is the solid earth; an error peculiar to minds which replace reason with logic.
