In their action, then, upon society, philosophers may hope for the energetic support of the working classes. But the regenerating movement requires still the co-operation of a third element, an element indicated by our analysis of human nature, and suggested also by historical study of the great crisis of modern times.
The moral constitution of man consists of something more than Intellect and Activity. These are represented in the constitution of society by the philosophic body and the proletariate. But besides these there is Feeling, which, in the theory put forward in the first chapter of this work, was shown to be the predominating principle, the motive power of our being, the only basis on which the various parts of our nature can be brought into unity. Now the alliance between philosophers and working men, which has been just described, however perfectly it may be realized, does not represent the element of Feeling with sufficient distinctness and prominence.
