In mature years I have always been gregarious, a lover of my kind, dependent upon the company of friends for the very pulse of moral life. To be marooned, to be shut up in a solitary cell, to inhabit a lighthouse, or to camp alone in a forest, these have always seemed to me afflictions too heavy to be borne, even in imagination. A state in which conversation exists not, is for me an air too empty of oxygen for my lungs to breathe it.
