We have mentioned once before that our conception of 'form' in organically active nature must not be limited merely to that of a body's spatial outline. This was in connexion with Ruskin's definition of the spiritual principle active in plant-formation as 'the power that catches out of chaos charcoal, water, lime and what not, and fastens them down into a given form'. Besides the external order of matter revealed in space-form, there exists also an inner qualitative order expressed in a body's chemical composition. Upon this inner chemical order is based all that we encounter as colour, smell, taste, etc., of a substance, as well as its nourishing, healing or harmful properties. Accordingly, all these parts of an organism, both in the plant-kingdom and within the higher organisms, have a certain inner material order, apart from their characteristic space-structure. The one is never present without the other, and in some way they are causally connected.
