"The first internal relation that is essential to a secret society is the reciprocal confidence of it..." — Georg Simmel

Discretion is nothing other than the sense of justice with respect to the sphere of the intimate contents of life.

Every relationship between persons causes a picture of each to take form in the mind of the other, and this picture evidently is in reciprocal relationship with that personal relationship.

Every relationship between two individuals or two groups will be characterized by the ratio of secrecy that is involved in it.

For, to be a stranger is naturally a very positive relation; it is a specific form of interaction.
