". . . The human order opens what Merleau-Ponty calls a ‘third dialectic’. Tied neither to a fact, nor to a delineated
type of situation, it institutes a domain of culture in which the object is in no immediate sense related to a biological function. This ‘third dialectic’ is characterized by “the Hegelian term ‘work’” (SB, 163). Following Kojève, Merleau-Ponty regards ‘work’ as instituting a delay between a biological stimulus and a response, thus opening a domain of culture. He argues that
Language, as a domain of signification, radically transcends the domain of a singular fact. Then he shows that between these three structures there is no equality, inasmuch as the study of nature, inanimate or animate, is accomplished in language. It is at this point that he cites Hegel approvingly: “The mind of nature is a hidden mind. It is not produced in the form of mind. It is only mind for the mind that knows it.” Then Merleau-Ponty continues, “In reality, we have already introduced consciousness, and what we have designated under the name of life was already consciousness of life. The concept is only the interior of nature, says Hegel. And already it seemed to us that the notion of a living body could not be grasped without the unity of signification, which distinguishes a gesture from a sum of movements” (SB, 161–162). Between consciousness and nature there is not a relation of exteriority. At this period in Merleau-Ponty's thought, Husserl's notion of
intentionality has not yet been integrated into his thinking. It could be said that the role Hegel played in
The Structure of Behavior has, in his later work, been displaced by Husserl. Nonetheless, the quote from Hegel's
Philosophy of Nature cannot but strike the reader of
The Visible and the Invisible where Merleau-Ponty speaks of the Invisible as the Invisible
of the Visible, as its lining.
In both the
Phenomenology of Perception and
The Visible and the Invisible, he elaborates a conception of the relationship between the body and the soul that both retains and transforms the conception presented in
The Structure of Behavior. Against Descartes, he claims that this relation is not a relationship between two substances which would in some way connect with one another. On the contray, the three structures are integrated, one into the other, in such a way that it reminds the reader of Hegel's notion of sublation (
Aufhebung) whereby the lower is both cancelled, as independent, and also retained. When this synthesis is accomplished, the autonomy of the lower is annulled; however, the synthesis can become undone, in which case the autonomy of the lower structure re-emerges. When this synthesis is effected, the lower structure does not exist as such. “The appearance of reason and mind does not leave intact a sphere of self-enclosed instincts” (SB, 181). Merleau-Ponty insists that when speaking of the physical, the vital and the human structures, one should not conceive of them as acting on one another in a causal manner. “Each of them has to be conceived as a retaking and ‘new’ structuralization of the preceding one” (SB, 184). Insofar as the ‘third dialectic’ has fully integrated the physical and the vital structures so that they no longer act as autonomous systems, one could say that “body and soul are no longer distinguished” (SB, 203). Nonetheless, when they disintegrate then they are experienced as distinct. Merleau-Ponty writes, “This is the truth of dualism” (SB, 209).
As we have seen, the
Gestalt does not exist as a thing in nature, rather it is viewed as an object of ‘knowledge’ for a subject. Thus we see that Merleau-Ponty comes to the threshold of transcendental philosophy, however, it is his ‘interrogation of the subject’ which blocks his entry into critical philosophy proper. He views this subject as neither the
substantial subject of Descartes, nor the Kantian “I think” that can accompany any possible experience, rather it is a subject which has itself been constituted by a dialectic of physical and vital structures. He tells us that we must relativize the notion of body and soul, since each moment of the dialectic is “…soul with respect to the preceding one, and body with respect to the following one” (SB, 210). The subject for whom nature appears is itself the result of a dialectic which is, in the sense indicated above, a part of nature. Thus, to the question that forms the title of the last chapter of
The Structure of Behavior, “Is there not a truth to naturalism?”, the answer is “Yes.” Merleau-Ponty's reflections on the being of the
Gestalt led him to Hegel who claims that “Nature is the exterior of the concept” (SB, 210), but for Hegel, when the concept becomes conscious of itself, it comes to see that it has no exterior. On the contrary, for Merleau-Ponty the
Gestalt must be conceived of as a unity of both nature and idea. This unity is intractable. There is in experience an “original text which cannot be extracted from its relationship to nature. The signification is embodied” (SB, 211). Thus we see that the consciousness for which the
Gestalt exists is not an intellectual consciousness, rather it is a perceptual consciousness. According to critical philosophy, nature becomes a system of representations which exists for a consciousness whose activity is the condition of its possibility as appearance. Its unity is engendered by the synthesis which the subject effects of itself by its apperception and which it articulates in the “Table of Judgments. . . .”
