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.
Georg SimmelGratitude, as it were, is the moral memory of mankind. In this respect, it differs from faithfulness by being more practical and impulsive: although it may remain, of course, something purely internal, it may yet engender new actions. It is an ideal bridge which the soul comes across again and again, so to speak, and which, upon provocations too slight to throw a new bridge to the other person, it uses to come closer to him.
Georg SimmelThe 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.
