more books... The idea of force in classical Newtonian mechanics (no longer, indeed, the only idea of what a force can be) is, if we reflect, in harmony with the pure geometry and kinematics of the space of Euclid. The primary characteristic of this kind of force is that in its spatial activity it is directed along a line, from point to point. We may describe the typical forces of the inorganic world as “centric forces”—forces working from center to center, that is, from point to point along the line that joins them. The archetypal instance of such a force is gravity; allied are all the characteristic forces of pressure and contraction. What kind of “force,” then, will be at work in the negative-Euclidean realm? The clear conclusion is that the primary force of such a space will be levitational, suctional, planar. The balanced duality of spatial theory will express itself also in the organic balance of a living form. In our times, it is of paramount importance to transcend the idea of a one-fold, point-centered, material world, in which man (one of many similar units) lives his life automatically accumulating substance and losing it again. The material world of Euclidean space is, after all, not the only aspect of the universe, though perhaps of necessity man has had to become so deeply immersed in this aspect that he has not been able to see clearly beyond its limitations. As we have seen here, in the perspective of projective geometry, the universe may more adequately be seen as three-fold, material and spiritual, with life sustained between these polar realms. A truer picture of such a cosmos reveals polarities which interplay and interweave to create the diverse forms in nature.When man in his conscious activity of thinking has taken a more profound step in the understanding of polarity, as distinct from mere contrast, he will come to a creative and fundamental use of the imagination in many fields. Contrasts such as expansion and contraction in physical space take on quite another aspect in the realm of the living. To the extent to which we can learn to understand the laws of the interweaving polarities and how to put them into practice, we shall perhaps be enabled to sort out the complicated tangle of modern life. Current methods of investigation into substances and the forces to which they are subject do not yet gain access to the whole of the living process; biochemistry and biophysics lean heavily on concepts which rest on quantitative mathematics and apply in the physical-mechanical realm. The impetus given by a quantitative mathematics has led to the development of a quantitatively minded world; it is an essential task for the future to develop the qualitative aspect of mathematics, so that the generations to come may in time achieve a true science of the living, conscious aspect of the world.
