2. The Position of Anthroposophy among the Sciences
What really confronts us in the culture of our age? This—that its thinking has become abstract; that one simply continues along the line of thought that takes us from planimetry, stereometry, etc., whereas reality leads us back at the fourth dimension into space. But, in turning back then, we are by no means where we were when we found our way into the third dimension by gauging distances. We return spiritually enriched. If we can think of the fourth dimension (the negative third) in such a way that we return with it into space, then space becomes filled with spirit, whereas three-dimensional space is filled with matter. And we find space filled with ever loftier spiritual configurations when we pass along the negative third and second and first dimension and reach the point where we no longer have spatial extension but stand within the unextended—the spiritual.
