Introduction

“There are many mighty things, but there is nothing more mighty than man.” Modern science expresses itself somewhat more modestly. It is not merely to his individual strength that man owes his power and superiority over the brute creation and over Nature, but in a far higher degree to an organized collaboration with his equals. The harmonious confederation of the many, the linking together of elementary forms into an organism of higher order, has led finally to a world-wide system of co-operating forces. By means of co-operation work is accomplished which would be utterly impossible to the individual. There are some kinds of collaboration which depend upon the nature of the task, which may be either too strenuous or else too complicated for the individual. Hence co-operation and differentiation are absolutely essential principles, and man has not been able to devise any ideas that will take their place or improve on them.
