He took their facts for granted. He knew no more than a firefly about rays — or about race or sex — or ennui — or a bar of music — or a pang of love — or a grain of musk — or of phosphorus — or conscience — or duty — or the force of Euclidian geometry — or non-Euclidian — or heat — or light — or osmosis — or electrolysis — or the magnet — or ether — or vis inertiae — or gravitation — or cohesion — or elasticity — or surface tension — or capillary attraction — or Brownian motion — or of some scores, or thousands, or millions of chemical attractions, repulsions or indifferences which were busy within and without him; or, in brief, of Force itself, which, he was credibly informed, bore some dozen definitions in the textbooks, mostly contradictory, and all, as he was assured, beyond his intelligence.
