Jan Christiaan Smuts. It is my belief that Holism and the holistic point of view will prove important in their bearings on some of the main problems of science and philosophy, ethics, art and allied subjects. These bearings are, however, not fully discussed in this work, which is more of the nature of an introduction, and is concerned more with the laying of foundations than with the superstructure. I have no time at present to do more than write an introductory sketch; but I hope in the years to come to find time to follow up the subject and to show how it affects the higher spiritual interests of mankind. The old concepts and formulas are no longer adequate to express our modern outlook. The old bottles will no longer hold the new wine. The spiritual temple of the future, while it will be built largely of the old well-proved materials, will require new and ampler foundations in the light of the immense extension of our intellectual horizons. This little book indicates the lines along which my own mind has trav elled in the search for new and more satisfactory concepts.
