"Never was there a greater need for the diffusion of knowledge, for in the present ignorance of men there is a very real and imminent danger. We have in the immediate future the possibility of serious struggle; we have all the elements of a possible social upheaval, and we have no religion with sufficient hold upon the people to check what may develop into a wild and dangerous movement. As yet philosophy is the study of the very few only, and the science which has done so much for us, and has achieved so many triumphs, cannot stay the danger which threatens us. The only thing that can prevent it is the diffusion of knowledge, so that men shall understand what is really best for them and shall realize that nothing can ever be good for one which is against the interests of the whole. p. 333"
