ABSTRACT
The biologists, accepting physical science as the model of all true science, have for the most part been resolutely blind to the abundant evidences of the causal efficacy of mental activity in the organic world. Economists of the highest repute tell us that it is not only a superstition but a most pernicious one, the main ground of all the economic sickness of the world in general and of Great Britain especially. Physical science has been the main agent in producing our chaos; and physical science can bring no remedy. The prestige accruing to physical science from the practical benefits it has conferred is the greater because those benefits are in the main obvious and unquestionable; and the fact that they have resulted directly from scientific research is easily grasped by the common man.
