*Differentiation in Integration*—Evolution (*parinam*) in its formal aspect is defined as differentiation in the integrated. In other words, the process of Evolution consists in the development of the differentiated within the undifferentiated, of the determinate within the indeterminate, of the coherent within the incoherent. The evolutionary series is subject to a definite law which it cannot overstep. The order of succession is not from the whole to parts, nor from parts to the whole,—but ever from a relatively less differentiated, less determinate, less coherent whole to relatively more differentiated, more determinate, more coherent whole. On the Samkhya view, increasing differentiation proceeds *pari pasu* with increasing integration within the evolving whole, so that by this two-fold process what was an incoherent, indeterminate, homogeneous whole evolves into a coherent, determinate, heterogeneous whole.
