As Easterbrook may have told you I have been considering an experiment in communication which is to follow the lines of this letter in suggesting means of linking a variety of specialized fields by what might be called a method of esthetic analysis of their common features. This method has been used by my friend Sigfried Giedion in Space, Time and Architecture and in Mechanization Takes Command. What I have been considering is a single mimeographed sheet to be sent out weekly or fortnightly to a few dozen people in different fields, at first illustrating the underlying unities of form which exist where diversity is all that meets the eye. Then, it is hoped there will be a feedback of related perception from various readers which will establish a continuous flow.
