The Way of all Flesh by Samuel Butler

On our way to town Ernest broached his plans for spending the next year or two. I wanted him to try and get more into society again, but he brushed this aside at once as the very last thing he had a fancy for. For society indeed of all sorts, except of course that of a few intimate friends, he had an unconquerable aversion. "I always did hate those people," he said, "and they always have hated and always will hate me. I am an Ishmael by instinct as much as by accident of circumstances, but if I keep out of society I shall be less vulnerable than Ishmaels generally are. The moment a man goes into society, he becomes vulnerable all round."

I was very sorry to hear him talk in this way; for whatever strength a man may have he should surely be able to make more of it if he act in concert than alone. I said this.
