Whitmanite

Did I not dispute a whole afternoon with another young man about the necessity for character, only to learn at the end of it that he didn't know what character was. He supposed it was 'something narrow and priggish—like what deacons used to be' And he, mind you, was in his twenties, and claimed, ore rotundo, to be a Whitmanite, a Shavian, and a socialist.

[Walt] Whitman gave [Edward] Carpenter a letter of introduction to his fan, Dr Richard Maurice Bucke and he set off, across the vast Lake Erie, to meet the Canadian Whitmanite, who was in charge of an insane asylum in the town of London.
