I shall now be able to place a similar plane perpendicularly through the Sun. Thus the movements of Jupiter, let us say, or of Mars, will be such that at one time it will stand on the right of this plane and then go across it and stand on the left. If I simply proceed abstractly, according to dimensions, I shall find it is sometimes on the right and sometimes on the left, and such and such a number of miles. But if I study cosmic space concretely, as I must [study] my own being as man, it is not a matter of indifference whether a planet is at one time on the left and at another time on the right, but I say there is the same kind of difference whether it is on the right or left as there is between a left and right organ. It is not sufficient to say that the liver is so many centimetres to the right of the symmetrical axis, the stomach so many centimetres to the left, for the two are dissimilar in formation because the one is a right organ and the other a left. Here it is so, that Jupiter, according as he is on the right or the left, to the eye appears different.
