What we have now brought to our awareness by studying man, holds good in some sense also for the animal. The animal, too, is polarized into motion and sensation. (What makes the animal differ from man need not concern us here, for it belongs to a dynamic realm other than the one we are now studying. This other realm will come under consideration in the next chapter.) Quite a different picture arises when we turn to the plant. The plant, too, is characterized by a threefold structure, root, stem with leaves, and florescence, which in their way represent the three alchemical functions. Consequently, there is also motion in the plant, although this is confined to internal movements leading to growth and formation. And at the opposite pole there is sensation, though again very different from the sensation experienced by higher living beings. What we mean here by 'sensation' can be best expressed by quoting the following passage from Ruskin's The Queen of the Air, in which the dual activity of the dynamic which we seek to understand is brought out particularly clearly.
