Three Orders of Signification

Merleau-Ponty's ontological-pivot thesis in The Structure of Behavior Ch III: matter, life, and mind are not powers of being but three orders of signification, distinguished by the type of equilibrium each achieves and the kind of integration of form each manifests. The three orders are integrated levels, not substantial strata — a distinction MP marks with deliberate terminological choice ("human order" — not "mental," not "rational"). The advent of a higher order eliminates the autonomy of the lower order; it does not supervene on it.

This is the philosophical core of SB. Chapters I–II earn the right to "form" through immanent critique of reflexology and Pavlov; Chapter III rotates "form" into ontology by naming three orders; Chapter IV uses the result to reformulate the soul/body problem. The integrationist reading at SB raw 1700 is the cardinal anti-stratification anchor that the dominant secondary reception of SB suppresses in favor of a layered reading.

Key Points

  • Distinguished by type of equilibrium:
    • Physical order (SB raw 1422): equilibrium "obtained with respect to certain given external conditions, whether it is a question of topographical conditions, as in the distribution of electrical charges on a conductor; or of conditions which are themselves dynamic, as in the case of a drop of oil placed in the middle of a mass of water." Forces redistribute under external action so as to advance toward rest. Quantity is the dominant category; signification is recessive. Examples: soap bubble, oil drop, falling bodies, electrical conductor.
    • Vital order (SB raw 1422): equilibrium "obtained, not with respect to real and present conditions, but with respect to conditions which are only virtual and which the system itself brings into existence." The organism executes work beyond its proper limits and constitutes a proper milieu for itself. Norm-bound preference; the organism as "ideal unity," "a melody which sings itself" (Uexküll). Order is dominant; signification present; quantity recessive. The organism is an *idea* (Goldstein's Erkenntnissgrund, not Seinsgrund), not a vital force, not an entelechy.
    • Human order (SB raw 1554): the dialectic of perceived situation–work. Equilibrium with respect to conditions virtual in a second sense — mediate and possible. Use-objects and cultural objects are instituted whose meaning is to be surpassed. The categorial attitude (Goldstein); capacity to orient toward the possible and the mediate; the same thing under a plurality of aspects. Signification is dominant. MP chooses Hegel's "work" (Arbeit) over "action" (raw 1556).
  • Universally applicable categories, each merely dominant: quantity, order, and signification are not the proprietary attributes of matter, life, and mind respectively. Each is universally applicable; each merely dominates in its order. Matter, life, and mind differ in degree of integration of form, not in substance.
  • Cardinal integration formula (SB raw 1700): "The advent of higher orders, to the extent that they are accomplished, eliminate the autonomy of the lower orders and give a new signification to the steps which constitute them. This is why we have spoken of a human order rather than of a mental or rational order."
  • Anti-rational-animal (SB raw 1708): "Man is not a rational animal. The appearance of reason and mind does not leave intact a sphere of self-enclosed instincts in man." Vital behavior as such disappears in the human; periodicity of animal sex becomes the constancy and variation of human sexuality; cognitive disorders affecting categorial attitude express themselves as loss of sexual initiatives.
  • Three dialectics, not three powers (SB raw 1730): "The 'physical,' the 'vital' and the 'mental' do not represent three powers of being, but three dialectics. … what we call nature is already consciousness of nature, what we call life is already consciousness of life and what we call mental is still an object vis-à-vis consciousness."
  • Each higher order is a retaking (reprise) and a 'new' structuration of the preceding one (raw 1730).
  • Ch IV's recap (SB raw 1870): the orders are rephrased as "three planes of signification or three forms of unity" — a more idealist phrasing than Ch III's, suggesting MP himself was aware Ch III's formulation could be heard as ontological-realist where his official position is structural-idealist.

What the Concept Does

The three-orders thesis performs four distinct argumentative jobs in SB:

  1. It dissolves the antinomies of substantialism. Materialism (one substance, physical), mentalism (substance-soul added), and vitalism (vital force added) are all rejected: they are different ways of treating form as a thing among things. The three-orders thesis treats form as a limit-concept of physical knowledge, an object of perception that physics presupposes — not a hidden layer of nature.

  2. It saves the empirical sciences without conceding to realism. Each order is real as a structure; each is not real as a substance. Biology can pursue the vital order rigorously; psychology can pursue the human order rigorously; physics can pursue the physical order rigorously. None of them is exhausted by the others, and none of them is autonomous in the sense substantialism requires.

  3. It grounds an integrationist (not stratified) reading of mind/life/matter relations. The higher order eliminates the autonomy of the lower (raw 1700). This is the cardinal anti-stratification anchor — and it is the doctrine the dominant secondary reception of SB suppresses in favor of a layered reading.

  4. It provides the framework Ch IV will use to reformulate the soul/body problem. The relativization of soul and body (raw 1934 — "Each of these degrees is soul with respect to the preceding one, body with respect to the following one") is grounded in the three-orders integrationism: there is no absolute soul or body; what we mean by these terms varies with the level of integration we are considering.

What It Rejects

  • Stratificationist mentalism: mind as "specific difference … added to vital or psychological being" (raw 1708).
  • The rational-animal definition: "Man is not a rational animal" (raw 1708).
  • Substantialist hierarchies: "two powers of being" — refused at raw 1700.
  • Materialism / mentalism / vitalism jointly: each treats form as a thing.
  • The "integral philosophy" that wants to include all three orders but cannot abandon realism.
  • Bergson's élan vital: "magical, not conceivable" (raw 1520).
  • Tolman's purposive behaviorism: still keeps "Only stimuli and responses are realities" (raw 1712); determinants are second-class.
  • Köhler's hope of reducing vital preference to least-energy / least-expenditure (raw 1436): "It is not because behavior is simple that it is preferred; on the contrary it is because it is preferred that we find it simpler."

Stakes

If the three-orders thesis is accepted as integrationist (and not stratified), the entire problem-space of mind/body, vitalism/mechanism, materialism/mentalism is reformulated. The classical problems become misformulated questions: there is no question "how does the mental supervene on the physical?" because there are no autonomous lower levels for higher levels to supervene on.

But there is also a cost: the asymmetric privilege of the human case is unargued. The human order is presented as a higher integration of the vital, but at no point does SB earn the verdict that the human is higher in any non-circular sense. A defender of biological continuism could refuse this and SB would have no internal reply.

The integrationist reading is what Phenomenology of Perception and Nature (1956–60) extend: the body's lived spatiality (PoP), the philosophy of nature drawing on Uexküll, Schelling, Whitehead (Nature) — both presuppose the three-orders integrationism and develop it without regression to substantialism.

Problem-Space

The problem-space SB enters here is how a transcendental philosophy can be integrated with empirical science without retreating to substantialism on either side. The classical problem ("relation of consciousness and nature") gets displaced: matter, life, and mind are no longer separate domains to be related but integrated levels of the same dialectical process.

This problem-space recurs across MP's corpus:

  • Phenomenology of Perception (1945): the body as the integrated level of vital and human dialectics (motor intentionality as the integration of biological motility with intentional comportment).
  • Nature (1956–60): explicit return to the three-orders question with Uexküll, Schelling, Whitehead, Bergson.
  • Visible and Invisible (1959–61): the flesh as the chiasmic integration of nature and culture.

The 1942 attestation of the integrationist reading is foundational; later MP develops it without regressing to layering.

Open Questions

  • Layered or integrated? MP's explicit doctrine is integrationist (raw 1700, 1708); the surface vocabulary ("hierarchy in which individuality is progressively achieved," "advent of higher orders") lends itself to layered readings. The dominant secondary reception of SB takes it as layered. The integrationist reading is the position-as-stated; the layered reading is the position-as-misread.
  • Idealist or realist? Ch III sometimes speaks ontologically (orders of reality) and sometimes structurally (orders of signification). Ch IV's recap at raw 1870 chooses the more idealist phrasing ("three planes of signification or three forms of unity"). Whether this is tactical (the soul/body argument requires anti-realist framing) or genuine drift is open.
  • The asymmetric privilege of the human case is unargued. The criterion "more integration" is internal to the framework that asserts integration; biological continuism could refuse this.
  • The relation between the three orders (Ch III) and the three forms of behavior (Ch II — syncretic / amovable / symbolic): they are not the same axis. The forms scale on whether structure emerges from content; the orders scale on what conditions equilibrium is sought against. The mapping is non-trivial and remains under-thematized in MP's own text.
