Georg Simmel,
The American Journal of Sociology…
“ The fruitful depth of relationships which, behind every latest revelation, implies the still unrevealed, which also stimulates anew every day to gain what is already possessed, is merely the reward of that tenderness and self-control which, even in the closest relationship, comprehending the whole person, still respect the inner private property, which hold the right of questioning to be limited by a right of secrecy. ”
