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

"The psychological basis of the metropolitan type of individuality consists in the intensification of nervous stimulation which results from the swift and uninterrupted change of outer and inner stimuli."

"Modern culture is constantly growing more objective. Its tissues grow more and more out of impersonal energies, and absorb less and less the subjective entirety of the individual."

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

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

"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."

"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."

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

"The individual has become a mere cog in an enormous organization of things and powers which tear from his hands all progress, spirituality, and value in order to transform them from their subjective form into the form of a purely objective life."

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

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

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

"In order to accommodate to change and to the contrast of phenomena, the intellect does not require any shocks and inner upheavals; it is only through such upheavals that the more conservative mind could accommodate to the metropolitan rhythm of events."

"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."

"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."

"In the latter case life rests upon a thousand presuppositions which the individual can never trace back to their origins, and verify; but which he must accept upon faith and belief."

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