That Crawford Tillinghast should ever have studied science and philosophy was a mistake. These things should be left to the frigid and impersonal investigator, for they offer two equally tragic alternatives to the man of feeling and action; despair, if he fail in his quest, and terrors unutterable and unimaginable if he succeed. Tillinghast had once been the prey of failure, solitary and melancholy; but now I knew, with nauseating fears of my own, that he was the prey of success. I had indeed warned him ten weeks before, when he burst forth with his tale of what he felt himself about to discover. He had been flushed and excited then, talking in a high and unnatural, though always pedantic, voice.
