Artists' Circles and the Development of Artists
In: Small group behavior, Band 13, Heft 4, S. 451-474
The best things come ... from the talents that are members of a group; every man works better when he has companions working in the same line, and yielding to the stimulus of suggestion, comparison, emulation. Great things have of course been done by solitary workers; but they have usually been done with double the pains they would have cost if they had been produced in more genial circumstances [Henry James, in Cowley 1973: 134].
