The idea as a process runs through three stages in its development. The first form of the idea is Life: that is, the idea in the form of immediacy. The second form is that of mediation or differentiation; and this is the idea in the form of Knowledge, which appears under the double aspect of the Theoretical and Practical idea. The process of knowledge eventuates in the restoration of the unity enriched by difference. This gives the third form of the idea, the Absolute Idea: which last stage of the logical idea evinces itself to be at the same time the true first, and to have a being due to itself alone. (a) _Life._ 216.] The _immediate_ idea is Life. As _soul,_ the notion is realised in a body of whose externality the soul is the immediate self-relating universality. But the soul is also its particularisation, so that the body expresses no other distinctions than follow from the characterisations of its notion. And finally it is the Individuality of the body as infinite negativity,--the dialectic of that bodily objectivity, with its parts lying out of one another, conveying them away from the semblance of independent subsistence back into subjectivity, so that all the members are reciprocally momentary means as well as momentary ends. Thus as life is the initial particularisation, so it results in the negative self-asserting unity: in the dialectic of its corporeity it only coalesces with itself. In this way life is essentially something alive, and in point of its immediacy this individual living thing. It is characteristic of finitude in this sphere that, by reason of the immediacy of the idea, body and soul are separable. This constitutes the mortality of the living being. It is only, however, when the living being is dead, that these two sides of the idea are different _ingredients._ * * * * * The single members of the body are what they are only by and in relation to their unity. A hand _e.g._ when hewn off from the body is, as Aristotle has observed, a hand in name only, not in fact. From the point of view of understanding, life is usually spoken of as a mystery, and in general as incomprehensible. By giving it such a name, however, the Understanding only confesses its own finitude and nullity. So far is life from being incomprehensible, that in it the very notion is presented to us, or rather the immediate idea existing as a notion. And having said this, we have indicated the defect of life. Its notion and reality do not thoroughly correspond to each other. The notion of life is the soul, and this notion has the body for its reality. The soul is, as it were, infused into its corporeity; and in that way it is at first sentient only, and not yet freely self-conscious. The process of life consists in getting the better of the immediacy with which it is still beset: and this process, which is itself threefold, results in the idea under the form of judgment, _i.e._ the idea as Cognition.
