If we unite the Notion of the concrete with that of development we have the motion of the concrete. Since the implicit is already concrete within itself, and we only set forth what is implicitly there, the new form which now looks different and which was formerly shut up in the original unity, is merely distinguished. The concrete must become for itself or explicit; as implicit or potential it is only differentiated within itself, not as yet explicitly set forth, but still in a state of unity. The concrete is thus simple, and yet at the same time differentiated. This, its inward contradiction, which is indeed the impelling force in development, brings distinction into being. But thus, too, its right to be taken back and reinstated extends beyond the difference; for its truth is only to be found in unity. Life, both that which is in Nature and that which is of the Idea, of Mind within itself, is thus manifested. Were the Idea abstract, it would simply be the highest conceivable existence, and that would be all that could be said of it; but such a God is the product of the understanding of modern times. What is true is rather found in motion, in a process, however, in which there is rest;difference, while it lasts, is but a temporary condition, through which comes unity, full and concrete.
We may now proceed to give examples of sensuous things, which will help us further to explain this Notion of the concrete. Although the flower has many qualities, such as smell, taste, form, colour, &c., yet it is one. None of these qualities could be absent in the particular leaf or flower:
each individual part of the leaf shares alike all the qualities of the leaf entire. Gold, similarly contains in every particle all its qualities unseparated and entire. It is frequently allowed with sensuous things that such varied elements may be joined together, but, in the spiritual, differentiation is supposed to involve opposition. We do not controvert the fact, or think it contradictory, that the smell and taste of the flower, although otherwise opposed, are yet clearly in one subject; nor do we place the one against the other. But the understanding and understanding thought find everything of a different kind, placed in conjunction, to be incompatible. Matter, for example, is complex and coherent, or space is continuous and uninterrupted. Likewise we may take separate points in space and break up matter dividing it ever further into infinity. It then is said that matter consists of atoms and points, and hence is not continuous. Therefore we have here the two determinations of continuity and of definite points, which understanding regards as mutually exclusive, combined in one. It is said that matter must be clearly either continuous or divisible into points, but in reality it has both these qualities. Or when we say of the mind of man that it has freedom, the understanding at once brings up the other quality, which in this case is necessity, saying, that if Mind is free it is not in subjection to necessity, and, inversely, if its will and thought are determined through necessity, it is not free - the one, they say, excludes the other. The distinctions here are regarded as exclusive, and not as forming something concrete. But that which is true, the Mind, is concrete, and its attributes are freedom and necessity. Similarly the higher point of view is that Mind is free in its necessity, and finds its freedom in it alone, since its necessity rests on its freedom. But it is more difficult for us to show the unity here than in the case of natural objects. Freedom can, however, be also abstract freedom without necessity, which false freedom is self-will, and for that reason it is self-opposed, unconsciously limited, an imaginary freedom which is free in form alone.
