We have to complete the consideration of Space by the consideration of Time

"The dominant influences in youth are those of the outer planets, Jupiter, Saturn, and Mars, and in later life the inner planets, Venus, Mercury, and the Moon. But the earliest and most conspicuous influence of all is that of the Moon. Thus we have to complete the consideration of Space by the consideration of Time. Only by these means can we learn to estimate and appreciate certain phenomena of human life and constitution."--Rudolf Steiner, March 27, 1920
