In Nature there are only rhythmical processes, there are none which continue into infinity. They revert rhythmically upon themselves. That is not only the case in quantitative dispersion, but also in qualitative. If you subdivide any substance, it has at first certain distinctive qualities. These qualities do not decrease and diminish ad infinitum; at a certain point, they are reversed and become their opposites. And this intrinsic rhythm is also the foundation of the contrast between the upper and lower organization. Our upper organization works in a homeopathic way. In a certain sense it is diametrically opposed to the process of ordinary digestion, its opposite and negative. Therefore we might say that when the homeopathic chemist manufactures his minute dilutions, he thereby transfers the qualities which are otherwise linked with the lower organic sphere into those which belong to the upper sphere. This is a most significant inner relationship and we shall discuss it in the ensuing lectures.
