processes as mutely and painlessly as we are now told that the minerals are metamorphosing themselves continually in the dark laboratory of the earth's crust? Thus this planet may be filled with beings who will be blind and deaf as the inmost rock, yet will execute changes as delicate and complicated as those of human language and all the intricate web of what we call its effects, without sensitive impression, without sensitive impulse: there may be, let us say, mute orations, mute rhapsodies, mute discussions, and no consciousness there even to enjoy the silence." "Absurd!" grumbled Trost. "The supposition is logical," said I. "It is well argued from the premises." "Whose premises?" cried Trost, turning on me with some fierceness. "You don't mean to call them mine, I hope." "Heaven forbid! They seem to be flying about in the air with other germs, and have found a sort of nidus among my melancholy fancies. Nobody really holds them. They bear the same relation to real belief as walking on the head for a show does to running away from an explosion or walking fast to catch the train." XVIII. THE MODERN HEP! HEP! HEP! To discern likeness amidst diversity, it is well known, does not require so fine a mental edge as the discerning of diversity amidst general sameness. The primary rough classification depends on the prominent resemblances of things: the progress is towards finer and finer discrimination according to minute differences. Yet even at this stage of European culture one's attention is continually drawn to the prevalence of that grosser mental sloth which makes people dull to the most ordinary prompting of comparison--the bringing things together because of their likeness. The same motives, the same ideas, the same practices, are alternately admired and abhorred, lauded and denounced, according to their association with superficial differences, historical or actually social: even learned writers treating of great subjects often show an attitude of mind not greatly superior in its logic to that of the frivolous fine lady who is indignant at the frivolity of her maid. To take only the subject of the Jews: it would be difficult to find a form of bad reasoning about them which has not been heard in conversation or been admitted to the dignity of print; but the neglect of resemblances is a common property of dulness which unites all the various points of view--the prejudiced, the puerile, the spiteful, and the abysmally ignorant.
