plementary differentiation. By this process 

 genius, greatness, and other sought qualities 

 are made. Equality is a conscious tendency 

 with no natural background. The uncon- 

 scious tendency is toward differentiation and 

 the inequality of strong, natural characters. 

 The two processes are thus supplementary. 

 If the economic process furnishes the material 

 in the shape of a widely diffused surplus, the 

 biologic process, when once started, will work 

 itself out unconsciously. Men need not think 

 of it, but they must think and plan for equal- 

 ity. It depends on the reversal of the natural 

 process by which the strong in men becomes 

 stronger. If, then, men work for genius 

 and neglect equality, they get neither; but if 

 they work for equality, they gain both genius 

 and equality. The one is the natural and 

 the other the acquired result of a surplus. 

 Each deficit leads to some elimination and 

 each surplus to some differentiation. Deficits, 

 therefore, eliminate the weak, while differen- 

 tiations create genius and the natural char- 

 acters through which it expresses itself. But 

 we should not forget that with every strong
