True, no man can be wholly apart from his fellows. But, if each of us is a promontory, yet the promontory reaches out beyond the social mainland to a point where others cannot intrude. Beyond that point lies an unexplorable lonesomeness, a unique privacy. It is a no-other-man's land, for others can't penetrate it, can't communicate with it.
