An organism is a system. The notion of system changes through history; it occupies different positions within the encyclopedia. This notion may be logico-mathematical: a coherent set of demonstrable propositions deduced from a small number of postulates. One speaks in this way of a system of axioms or a system of differential equations. For Descartes, Spinoza, or Leibniz, this is the classical ideal of knowledge. The notion of system may also be mechanical: a set which remains stable throughout variations of objects which are either in movement or relatively stationary. Laplace speaks in this sense of the solar system. Within a set of mobile material points distributed in space and governed by a law - Newton's law, for example-it is clear that time is fully reversible. If everything starts moving in the opposite direction, nothing significant in form or state will change. The mathematical or logical system is independent of the time variable; the ordinary mechanical system depends on a time but not on its direction. Hence the displacement, starting with the Industrial Revolution, toward physics and in particular toward the theory of heat, a displacement occurring after Fourier starting with Carnot. In another essay(1) I have called mechanical systems "statues" or stateurs: they are based on a fixity or an equilibrium. After Carnot they become motors. They create movement, they go beyond the simple relation of forces, they create them by energy or power. They produce circulation by means of reservoirs and differences of temperature. As soon as one can build them and theorize about them-steam or combustion engines, chemical, electrical, and turbine engines, and so forth -the notion of time changes. The second law of thermodynamics accounts for the impossibility of perpetual motion of the second type; energy dissipates and entropy increases. From this moment on, time is endowed with a direction. It is irreversible and drifts from order to disorder, or from difference to the dissolution or dissemination of a homogeneous mixture from which no energy, no force, and no motion can arise.
Curiously enough, philosophers and psychologists, who never hesitated to adopt as models systems like the first ones, tables of axioms or statues, were often averse, during the nineteenth century, to this new development and to its practical and theoretical results. Almost all of them attempted to find some failing with it: they wished, I believe, that the motor would never stop. With very few exceptions, almost all of them maintain, for example, the existence of an eternal return, despite findings to the contrary in physics. Freud, however, aligns himself with these findings: he manifestly adopts as an initial model a topology like that of Maxwell and Listing,(2) in which lines of force are already called complexes, and an energy theory based on thermodynamics and linked to two fundamental principles: the conservation of energy and the tendency toward death. Freudian time is irreversible.
We are in the presence of three types of systems: the first, logico-mathematical, is independent of time; the second, mechanical, is linked to reversible time; the third, thermodynamic, is linked to irreversible time. However, the three types all have closure in common. They constitute a partitioning of a given universe, either by the so-called closure axiom for the universe of discourse or by the independence of movements and stabilities in relation to all exterior influences (thus Laplace's solar world in relation to the stellar universe) or by thermal insulation. A physical system, in the third sense, is isolated-closed. One must understand by this that no flow of matter, no circulation of heat, light, or energy, crosses the walls that define it and demarcate it in space. Under this condition and this condition only, the two laws of thermodynamics apply and are valid. With the slightest opening, the system is no longer governed by general equations.
Hence the general displacement of philosophical discourse from the nineteenth century to Bergson's posterity. Once couched in terms of differences, reservoirs and circulation, energies, power and relations of force, time and motors, deviations, oppositions and dissolution, suddenly this discourse, as if reverting to the conditions of its own practice, begins speaking in terms of open and closed, of isolation and closures. Today, in many respects, it has not progressed an inch in relation to the global problematic of Bergsonism. It has the same form and function, let us say the same syntax, but it has changed domains. Instead of addressing the direct questions of matter and life, from which, precisely, this language had developed, it brought that language within the domain of the social sciences, language, and texts. Why?
For a very simple reason. Nineteenth-century thermodynamics, restricted or general, classical or statistical, had studied motors and, in general, systems, producers of movement. The energies mobilized by its application and calculated by its theory remained on an entropic scale, by which I mean within the realm of ordinary work and the displacement of objects. Hence one had a discourse which often concluded either with the cosmos in general or with organic life in particular. At the beginning of the twentieth century, communication theory introduced a series of concepts such as information, noise, and redundancy, for which a link to thermodynamics was rather quickly demonstrated. It was shown, for example, that information (emitted, transmitted, or received) was a form of negentropy. Now these energies, manipulated and calculated, were of a different order than energy of the first, or macroscopic, scale-they were very small in relation to this scale. But this change only minimally affected the whole of the theoretical armature already in place: information theory was considered the daughter of thermodynamics; theorizing immediately began about activities as ordinary as reading, writing, the transmission and storing of signals, the optimal technique for avoiding obstacles along their path, and so forth. Of course, the theoreticians of information theory accomplished this with means inherited directly from the physics of energies belonging to the macroscopic scale. Success confirmed their enterprise. Hence, in a parallel manner, the great stability of traditional philosophical categories but their massive application in a different area: discourse, writing, language, societal and psychic phenomena, all acts which one can describe as communication acts. It immediately became obvious, or was taken as such, that a store of information transcribed on any given memory, a painting or a page, should drift by itself from difference to disorder, or that an isolated-closed system about which we know nothing, an unknown of some sort, could be and, in certain cases, had to be a language pocket. By an act of simultaneous translation one can derive with relative ease the philosophical terms in use today. The system under consideration becomes a system of signs.
Right in the middle of the traditional classification of beings, a classification that no longer makes sense since matter, life, and sign are nothing but properties of a system, we find exactly what I want to talk about: the living organism. Most often conceived of according to the models we have already considered, the organism has been seen as a machine (by figures and movements, or by invariance through variations) from the classical age up to the recent notion of homeostasis. Equilibrium and mobility. It is evidently a thermodynamic system, sometimes operating at very high temperatures, and tending toward death according to an unpredictable and irreversible time (that of ontogenesis), but going up the entropic stream by means of phylogenetic invariances and the mutations of selection. It is a hypercomplex system, reducible only with difficulty to known models that we have now mastered. What can we presently say about this system? First, that it is an information and thermodynamic system. Indeed, it receives, stores, exchanges, and gives off both energy and information-in all forms, from the light of the sun to the flow of matter which passes through it (food, oxygen, heat, signals). This system is not in equilibrium, since thermodynamic stability spells death for it, purely and simply. It is in a temporary state of imbalance, and it tends as much as possible to maintain this imbalance. It is hence subject to the irreversible time of the second law, since it is dying. But it struggles against this time. We can improve upon the classical formulation of this problem. Indeed, due to the energy and information torrent which passes through the system without interruption, it is henceforth impossible to conceive of it as an isolated-closed system, except, perhaps, in its genotypical form. It is an open system. It should thus be regulated by a thermodynamics of open systems which has been developing over the past ten years and which provides a complex theory for this state of imbalance. In and by this imbalance, it is relatively stable. But here invariance is unique: neither static nor homeostatic, it is homeorrhetic. It is a river that flows and yet remains stable in the continual collapse of its banks and the irreversible erosion of the mountains around it. One always swims in the same river, one never sits down on the same bank. The fluvial basin is stable in its flux and the passage of its chreodes; as a system open to evaporation, rain, and clouds, it always-but stochastically-brings back the same water. What is slowly destroyed is the solid basin. The fluid is stable; the solid which wears away is unstable - Heraclitus and Parmenides were both right. Hence the notion of homeorrhesis.(3) The living system is homeorrhetic.
This river, almost stable although irreversible, this basin, poised on its own imbalance in a precarious state of quasi-equilibrium in its flow toward death, ferries energy and information, knowledge of entropy and negentropy, of order and disorder. Both a syrrhesis (rather than a system) and a diarrhesis,(4) the organism is hence defined from a global perspective. Not actually defined (the word means in effect the opposite of open), but assessed, described, evaluated, and understood. Or, within the context of an even more general circulation which goes from the sun to the black depths of space, the organism is a barrier of braided links that leaks like a wicker basket but can still function as a dam. Better yet, it is the quasistable turbulence that a flow produces, the eddy closed upon itself for an instant, which finds its balance in the middle of the current and appears to move upstream, but is in fact undone by the flow and re-formed elsewhere. And experience shows that there is no flux without eddy, no laminar flow which does not become turbulent.(5) Now, and here is the crux of the matter, all times converge in this temporary knot: the drift of entropy or the irreversible thermal flow, wear and aging, the exhaustion of initial redundancy, time which turns back on feedback rings or the quasi-stability of eddies, the conservative invariance of genetic nuclei, the permanence of a form, the erratic blinking of aleatory mutations, the implacable filtering out of all non-viable elements, the local flow upsteam toward negentropic islands-refuse, recycling, memory, increase in complexities. The living organism, ontogenesis and phylogenesis combined, is of all times. This does not at all mean that it is eternal, but rather that it is an original complex, woven out of all the different times that our intellect subjects to analysis or that our habits distinguish or that our spatial environment tolerates. Homeorrhetic means at least that: the rhesis flows, but similarity pushes upstream and resists. All the temporal vectors possessing a directional arrow are here, in this place, arranged in the shape of a star. What is an organism? A sheaf of times. What is a living system? A bouquet of times.
It is indeed surprising that this solution has not been reached more quickly. Perhaps it seemed difficult to intuit a multitemporality. We willingly accept, however, the fact that the things around us do not all share the same temporality: negentropic islands on or in the entropic sea, or distinct universes as Boltzmann described them, pockets of local orders in rising entropy, crystal depositories sunk in ashes-none of these things disturbs us. Living syrrhesis combines sea and islands. In a completely new sense, the organism is synchronous for meanings and directions, for the continuous and discontinuous, for the local and the global; it combines memory, invariance, plan, message, loss, redundancy, and so forth. It is old, mortal, and the transmitter of a new cycle. The organism is fixed on top of a temporal converter -no, it is a converter of time. This is perhaps why it is able to learn about systems differentiated by their individual time: the world, fire, and signs.
Let us shift from the global to the local level, from the whole of the organism to the diverse systems that used to be called respiratory, circulatory, neurovegetal, and so forth, and then to organs, tissues, cells, molecules.... The passage could be plotted from homeorrhesis to homeorhesis. In short, from this point of view the complex functions like a set of chemical reactions. The latter occur, in the case of mammals-of which man is one -at high temperatures, indeed, very high, in a homoiothermal environment.(6) There exist approximately a thousand different reactions of this kind. But at a given moment, for the complex in operation (living), their number, although probably finite, is incredibly large, in view of the enormous molecular population. For an idea of its dimensions it must be placed on an astronomical scale. From a thermal and information point of view, these movements and transformations necessarily generate background noise. And this noise is certainly tremendous, for the numbers under consideration are gigantic. What prevents us from hearing it? Why is the sound muffled, the factory insulated?
All of information theory and hence, correlatively, of the theory of noise only makes sense in relation to an observer who happens to be linked to them. Who is the observer here? The simplest answer would be to say that for our own organic system we are the Observer or observers in question. Thus we should perceive this noise, the noise of a complex to which a receptor is linked. I use "perceive" in the broad sense that this word had in the classical era. We should hear this deafening clamor just as we hear the roar of the sea at the edge of the beach. It should deafen us, drown us. Leibniz said the following in his language: the cloud of minor perceptions, external and internal, should induce a state of discomfort and dizziness; it should prove intolerable. But, save for exceptional instances, we perceive almost nothing of this intense chaos which nonetheless exists and functions, as experiments have demonstrated conclusively. We are submerged to our neck, to our eyes, to our hair, in a furiously raging ocean. We are the voice of this hurricane, this thermal howl, and we do not even know it. It exists but it goes unperceived. The attempt to understand this blindness, this deafness, or, as is often said, this unconsciousness thus seems of value to me. We have eyes in order not to see ourselves, ears in order not to hear ourselves. The observer observes nothing, or almost nothing.
At this point it is necessary to consider the general conditions of organic functioning, the system's globalizing forms. All that we now know about it leads us to describe a series of successive apparatuses called levels of integration -Russian dolls or interlocking objects, according to the image Francois Jacob proposed.(7) The cybernetic model temporarily allows us to imagine certain links between these levels, from molecular activity to the organization of the cell, tissues, organs, and so forth. In relatively simple cases it would even be possible to write a mathematical model, a system of differential equations representing cellular activity. The conditions at the limits of that activity would describe the state of the boundaries, the limits of the level under consideration, and hence the nature of the proximity of one level to the next, the manner in which one level is submerged in the next. This process of proximity, of implication, of integration merits description. Consider any level of an interlocking system. Locally, as we have seen, it operates like a series of chemical reactions at a certain temperature. Let us forget for the moment their precise equations and the unique elements at work here. Let us consider only the energy conditions at this one level. It mobilizes information and produces background noise. The next level in the interlocking series receives, manipulates, and generally integrates the information-background noise couple that was given off at the preceding level. How does this take place? Several recent studies allow us to elucidate the answer to this question.(8) Indeed, if one writes the equation expressing the quantity of information exchanged between two stations through a given channel and the equation which provides this quantity for the whole unit (including the two stations and the channel), a change of sign occurs for a certain function entering into the computation. In other words, this function, called ambiguity and resulting from noise, changes when the observer changes his point of observation. Its value depends on whether he is submerged in the first level or whether he examines the entire unit from the next level. In a certain sense, the next level functions as a rectifier, in particular, as a rectifier of noise. What was once an obstacle to all messages is reversed and added to the information. This discovery is all the more important since it is valid for all levels. It is a law of the series which runs through the system of integration. I now come back to my initial question.
This question only made sense if, at the last level, the most comprehensive of the whole system, the present observer, to whom the noise and information phenomena are linked, had at his disposal or was equipped with a special listening instrument. A point of observation is not sufficient; to observe, one also needs the means to do so. Now the apparatus exists: it is made up of what classical philosophy called internal sensations or what different psychologies have successively described as intropathy, proprioceptivity, or coenesthesia, and whose functionings have to be linked to signals given off or received by the vagosympathetic system. The instrument exists and functions. What does it perceive? Nothing, or almost nothing, it seems, of what we recognize at the purely physical level as background noise and information; nothing which resembles, with perhaps certain exceptions, a signal -a figure against a ground - isolated from a vague and fluctuating cloud, from a multiple halo humming and buzzing at random. It does, however, perceive the signals that we subsume under the two broad categories of pleasure and pain. It receives them and emits them. It is not meaningless to say that it receives signals that we translate immediately into these two words. Thus everything would take place as if pleasure and pain constituted the final state of a general listening, filtered in turn by the set of successive integrations. The final couple, the only one to be perceived, would, in other words, be the last translation, the last rectification of the original physical couple of information-background noise. Of course, no one can call information fortunate and noise painful, for things are arranged in any number of chiasms. Suffering, at least sometimes, is a set of signals which opens up a path of readaptation or strategies for the repair, for the rebalancing, of the homeorrhesis. Here again, a change in sign appears. There must be noise in pleasure and information in pain. But this is probably something we cannot know or evaluate properly. It is significant that the successive levels of organic integration-we understand the chain of the first levels fairly well thanks to the experimental sciences, and we also understand the final segment because of the direct pathetic tie we maintain constantly with our own body-must always function as languages. On the one hand, at the cellular or molecular level, a proto-language (stereospecific information and thermal noise) is already functioning; on the other hand, at the most highly integrated level, a language is still functioning, but now as individuated signals equipped with something like meaning: calls for desired objects or warnings against dangerous ones. And again, because chiasms and ambiguity complicate matters, we can find a refusal of desire and a call for suffering. Hence the multiple, integrated system, about whose implicative surroundings I often know nothing, may be considered as a series of transformations which effects a move from the noise-information couple to the meaning-obstacles couple and finally to meaning. Each integration functions as a filter, a rectifier. We thus have a hypercomplex apparatus that finally gives a meaning to the Shannon couple-which can only be dealt with as long as it has no meaning.(9) Everything transpires as if the central problem of information theory were resolved, automatically, by living organisms. They can be described as apparatuses which produce language from noise and information, each according to its order of complexity: for each system, indeed, for each species, there exists an original set of signals.
For this reason it is simple to generalize several categories or ordinary functions. Repression in the Freudian sense, for example, remained an enunciation based on a mechanical or hydrodynamic model. Henceforth the entire integrative system can take charge of it; its physical model is much more complete and we can speak about it by using a discourse which ultimately can be expressed in mathematical terms. This is because we are dealing with a very general function operating in the proximity of two given levels. On one side, transformations, fixations, a set of energy displacements occur-no metaphor is needed here, for the processes under consideration are simply chemical or thermodynamic. On the other side, the entire complex of these movements is grasped by the observer, that is, by the integrating level as such, by the change in sign of the ambiguity function.
These matters are straightforward. Let us imagine a system with two or several elements. In an initial case, these elements are either completely different or identical with one another, repetitive. The information quantity is thus either a sum or a reduction to the information of a single element. This is the case of disorganization, of inorganization. If the system is organized, the elements are in relation to one another and are therefore different and similar at the same time. Here ambiguity arises. From a point of view within the system, the transmission of information along a given circuit from one element to another subtracts ambiguity because it is a noise, an obstacle to the message. For an observer outside the system, ambiguity must be added, for it increases the system's complexity. It functions in this case as information at the level of the unit's organization. In one case, it covers up; in the other case, it expresses. The entire symbolic function is embedded in this process, the entire strategy of free association, Freudian slips, jokes and puns. Now the point is that the theory of changes in sign is valid at the most elementary levels: a cell containing a nucleus, cytoplasm, membranes, and organelles. Henceforth, despite the most radical differences between embedded systems, they will at least share this process of reversal at their boundaries. Repression is only a particular example of this general process, which lays down the law for the chain. It is probably for this reason that we perceive nothing of the deafening background noise given off by the system, except for interesting pieces of information relating to the general functioning of these transformations or to their local breakdown. The senseless din is made meaningful by the series of rectifiers.
At this point the unconscious gives way from below; there are as many unconsciouses in the system as there are integration levels. It is merely a question, in general, of that for which we initially possess no information. It is not a unique black box, but a series of interlocking boxes; and this series is the organism, the body. Each level of information functions as an unconscious for the global level bordering it, as a closed or relatively isolated system in relationship to which the noise-information couple, when it crosses the edge, is reversed and which the subsequent system decodes or deciphers. In each link of the series the question of language is formulated and reformulated by the transformation of the message, the channel, and the noise: by translation. In fact, residual background noise is progressively eliminated: what was supposed to interfere begins constructing; obstacles combine to organize; noise becomes dialect. I imagine this occurs from the depths of the molecular chaos, in which information appears in its spatial simplicity and material forms, throughout the signifying and articulated message through the sequence of rectifiers. What remains unknown and unconscious is, at the chain's furthermost limit, the din of energy transformations: this must be so, for the din is by definition stripped of all meaning, like a set of pure signals or aleatory movements. These packages of chance are filtered, level after level, by the subtle transformer constituted by the organism, and they come crashing at our feet, like the surf at the edge of the beach, in the forms of eros and death. In this sense the traditional view of the unconscious would seem to be the final black box, the clearest box for us since it has its own language in the full sense. Beyond it we plunge into the cloud of meaningless signals. Perhaps this box protects us from the deafening gasps of the stochastic; perhaps the box serves to turn them. back into symbols. The unconscious is the last black observer of chance. It is an instance of order. It, too, turns destructive randomness into autonomy.
In this way, more generally, categories or common functions of psychoanalysis could be rewritten in terms of the new organon which maintains the advantage of being at the same time a physics of energy and a theory of signals. Formerly, when a given system was analyzed it was a standard -and justifiable-practice to write two distinct accounts of it: the energy account and the information account. For a computer this would be the bits on IBM cards or the like plus the necessary energy for heating the filaments. The two accounts had no proportion in common; they were not even on the same scale. An enormous coefficient separated them (10-16). The same thing is not true for the organism: its extreme complication, the great miniaturization of its elements, and their number bring these two accounts closer and make them comparable. Hence the difference between a machine and a living organism is that, for the former, the information account is negligible in relationship to the energy account, whereas, for the latter, both accounts are on the same scale. Henceforth, the theoretical reconciliation between information theory and thermodynamics favors and advocates the practical reconciliation between those funds of knowledge which exploited signs and those which exploited energy displacements: this was Freud's first dream.(10)
The change in sign for the ambiguity function now resolves an earlier difficulty. It had not been inelegant to conclude that the organism combines three varieties of time, and that its system constitutes a temporal sheaf. No simple matter for intuition, this conclusion remained unexplained. Now it is clear. Let us again consider the rectification of what is transmitted from one level to another. Background noise, the major obstacle to messages, assumes an organizational function. But this noise is the equivalent of thermal disorder. Its time is that of increasing entropy, of that irreversible element which pushes the system toward death at maximum speed. Aging, for example, is a process that we are beginning to understand as a loss of redundancies and the drifting of information into background noise. If the integration levels function correctly as partial rectifiers and transform the noise of disorder into potential organization, then they have reversed the arrow of time. They are rectifiers of time. Entropic irreversibility also changes direction and sign; negentropy goes back upstream. We have discovered the place, the operation, and the theorem where and with which the knots of the bouquet are tied. It is here and in this manner that time flows back and can change direction. Due to the numerous reversals of the temporal vector, the fluctuating homeorrhesis acquires a fleeting stability. For a moment the temporal sheaf makes a full circle. It forms a turbulence where opposing times converge. Organization per se, as system and homeorrhesis, functions precisely as a converter of time. We now know how to describe this converter, as well as its levels and meanderings, from whence come anamnesis, memory, and everything imaginable.
The body is an extraordinarily complex system that creates language from information and noise, with as many mediations as there are integrating levels, with as many changes in sign for the function which just occupied our attention. I know who the final observer is, the receiver at the chain's end: precisely he who utters language. But I do not know who the initial dispatcher is at the other end. I am confronted indefinitely with a black box, a box of boxes, and so forth. In this way, I may proceed as far as I wish, all the way to cells and molecules, as long, of course, as I change the object under observation. All I know, but of this I am certain, is that they are all structured around the information-background-noise couple, the chance-program couple or the entropy-negentropy couple. And this holds true whether I describe the system in terms of chemistry, physics, thermodynamics, or information theory, and whether I situate myself as the final receptor of an integrated apparatus. By reversing the ambiguity function, things naturally converge. Either I am submerged in signal exchanges or I observe the global set of exchanges. But from now on I understand and can explain what happens when the observer changes his point of view, when the subject becomes object, and the obstacle becomes a piece of information, or when introspection veers off into experience, and psychology flows into physics. Inversely, when the object becomes subject it temporarily increases its autonomy. Everything occurs as if Freud, who started from energy models of thermodynamics, had intuited, by a dynamics of language, the subsequent development of thermodynamics into information theory. The reunions are not exactly unexpected. The realms of the subjective and of the objective are no longer at odds. The observer as object, the subject as the observed, are affected by a division more stable and potent than their antique separation: they are both order and disorder. From this moment on, I do not need to know who or what the first dispatcher is: whatever it is, it is an island in an ocean of noise, just like me, no matter where I am. It is the genetic information, the molecules or crystals of the world, the interior, as one used to say, or the exterior -none of this is important any longer. A macro-molecule, or any given crystallized solid, or the system of the world, or ultimately what I call "me"-we are all in the same boat. All dispatchers and all receivers are structured similarly. It is no longer incomprehensible that the world is comprehensible. The real produces the conditions and the means for its self-knowledge. The "rational" is a tiny island of reality, a rare summit, exceptional, as miraculous as the complex system that produces it, by a slow conquest of the surf's randomness along the coast. All knowledge is bordered by that about which we have no information.
It is no longer necessary to maintain the distinction between introspective knowledge, or "deep" knowledge, and objective knowledge. There is only one type of knowledge and it is always linked to an observer, an observer submerged in a system or in its proximity. And this observer is structured exactly like what he observes. His position changes only the relationship between noise and information, but he himself never effaces these two stable presences. There is no more separation between the subject, on the one hand, and the object, on the other (an instance of clarity and an instance of shadow). This separation makes everything inexplicable and unreal. Instead, each term of the traditional subject-object dichotomy is itself split by something like a geographical divide (in the same way as am I, who speak and write today): noise, disorder, and chaos on one side; complexity, arrangement, and distribution on the other. Nothing distinguishes me ontologically from a crystal, a plant, an animal, or the order of the world; we are drifting together toward the noise and the black depths of the universe, and our diverse systemic complexions are flowing up the entropic stream, toward the solar origin, itself adrift. Knowledge is at most the reversal of drifting, that strange conversion of times, always paid for by additional drift; but this is complexity itself, which was once called being. Virtually stable turbulence within the flow. To be or to know from now on will be translated by: see the islands, rare or fortunate, the work of chance or of necessity.

(6) Homoiothermy is a similar example of homeorrhesis. In a certain sense, the poikilothermal, or cold-blooded, organism is better adapted to the environment. The homoiothernial organism, of more recent date in the history of evolution, is more fragile. It is probably condemned to a niche adjusted for relatively stable temperature intervals. In fact, it produces them as often as possible. Bees had already discovered this process for their hives. Hence the homoiothermal organism is much more dependent than other species on the environment, on its own species, and on the Other or Others. This is especially true when its offspring -and this is the case for a human infant- has not received at birth a perfect set of homoiothermal equipment. The homoiothermal organism generates the need for communication. It is, in energy or thermal needs, analogous to what will be common speech, in terms of signals and information. I imagine that one of the first forms of behavior, like one of the first signals, may be reduced to this: "keep me warm." The homoiothermal organism initiates touch and contact, erotic communication, and language. It is a homeology.
