Thus, the technique of metropolitan life is unimaginable without the most punctual integration of all activities and mutual relations into a stable and impersonal time schedule.

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

The intellectually sophisticated person is indifferent to all genuine individuality, because relationships and reactions result from it which cannot be exhausted with logical operations.

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

Secrecy sets barriers between men, but at the same time offers the seductive temptation to break through the barriers by gossip or confession.

Secrecy involves a tension which, at the moment of revelation, finds its release.

The deepest problems of modern life derive from the claim of the individual to preserve the autonomy and individuality of his existence in the face of overwhelming social forces, of historical heritage, of external culture, and of the technique of life.

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

Man's nature, originally good and common to all, should develop unhampered.

On the one hand, life is made infinitely easy for the personality in that stimulations, interests, uses of time and consciousness are offered to it from all sides. They carry the person as if in a stream, and one needs hardly to swim for oneself.

Cities are, first of all, seats of the highest economic division of labor.

Every superior personality, and every superior performance, has, for the average of mankind, something mysterious.

Secrecy is thus, so to speak, a transition stadium between being and not-being.

The first internal relation that is essential to a secret society is the reciprocal confidence of its members.

The metropolis has always been the seat of the money economy.

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.

For the division of labor demands from the individual an ever more one-sided accomplishment, and the greatest advance in a one-sided pursuit only too frequently means dearth to the personality of the individual.

For the metropolis presents the peculiar conditions which are revealed to us as the opportunities and the stimuli for the development of both these ways of allocating roles to men.

For this reason, strangers are not really conceived as individuals, but as strangers of a particular type: the element of distance is no less general in regard to them than the element of nearness.
