Organisms are purposive (“teleological”) beings. Nothing could be more obvious. The fact of the matter is so indisputable that even those who don’t believe it really do believe it. Philosopher of biology Robert Arp speaks for biology as a whole when he writes,

Thinkers cannot seem to get around [evolutionary biologist Robert] Trivers’ claim that “even the humblest creature, say, a virus, appears organized to do something; it acts as if it is trying to achieve some purpose”, or [political philosopher Larry] Arnhart’s observation that … “Reproduction, growth, feeding, healing, courtship, parental care for the young — these and many other activities of organisms are goal-directed”.1

And yet, despite his acknowledgment that we “cannot get around” this truth, Arp again speaks for almost the entire discipline of biology when he tries, with some delicacy, to take it all back: “with respect to organisms, it is useful to think as if these entities have traits and processes that function in goal-directed ways” (his emphasis). This as if is a long-running cliché, designed to warn us that the organism’s purposive behavior is somehow deceptive — not quite what it seems. The goal-directedness is, in the conventional terminology, merely apparent or illusory. Certainly it must not be seen as having any relation at all to human purposive activity — an odd insistence given how eager so many biologists are to make sure we never forget that the human being is “just another animal”.

Others have commented on this strange reluctance to acknowledge fully the purposiveness that is there for all to see. The philosopher of science, Karl Popper, said that “The fear of using teleological terms reminds me of the Victorian fear of speaking about sex”.2 Popper may have had in mind a famous remark by his friend and twentieth-century British evolutionary theorist, J. B. S. Haldane, who once quipped that “Teleology is like a mistress to a biologist; he cannot live without her but he’s unwilling to be seen with her in public”.3

We find — and will later explore further — this same unwilling yet inescapable conviction of purposiveness at the foundations of evolutionary theory. The theory, we are often told, is supposed to explain away the organism’s purposes — “naturalize” them, as those who claim to speak for nature like to say. But at the same time the theory is itself said to be grounded solidly in the fact that organisms, unlike rocks, thunderstorms, and solar systems, struggle to survive and reproduce. If they did not spend their entire lives striving toward an end, or telos, in this way, natural selection of the fittest organisms (those best qualified to survive and reproduce) could not occur. So it is not at all clear how selection is supposed to explain the origin of such end-directed behavior.

This double stance — believing and not believing, acknowledging and explaining away — constitutes, you could almost say, the warp and woof of biology itself. Look for “purpose” in the index of any biological textbook, and you will almost certainly be disappointed. That term, along with others such as “meaning” and “value”, is effectively banned. There is something like a taboo against it. Yet, in striking self-contradiction, those textbooks are themselves structured according to the purposive activities, or tasks, of organisms. Biologists are always working to narrate goal-directed achievements. How is DNA replicated? How do cells divide? How does metabolism supply energy for living activity? How are circadian rhythms established and maintained? How do animals arrive at the evolutionary strategies or games or arms races through which they try to eat and avoid being eaten?

Such questions are endless, and their defining role is reflected on every page of every textbook on development, physiology or evolution. A research question is biological, as opposed to physical or chemical, only when it is posed in one way or another by the organism’s purposive, future-oriented activity. The puzzle is that the answers biologists are willing to offer, on the other hand, are rooted with equal consistency in the assumption that organisms have no purposes. The reigning conviction is that explanations of physical and chemical means effectively remove any need to deal scientifically with the ends that alone could have prompted our search for means in the first place.

There is a curious phenomenon called blindsight, observed in some humans. Those afflicted with it lack a conscious power of vision, but experiments show they nevertheless can identify certain visual features of the world around them, or even to catch a ball thrown toward them. Given the biologist’s obvious recognition of meaning and purpose despite a failure of conscious or theoretical apprehension, perhaps we should, by analogy, speak of “biology’s blindsight”.

But whereas blindsight typically arises from brain damage, the biologist’s perceptual disorder is more a matter of philosophical distaste and consequent repression. And one way to repress such distasteful content is to “rediscover” it somewhere less threatening. This happens when, through the language of mechanism, biological purpose is projected upon the machines with which organisms are identified. Or, in the case of evolutionary theory, the organism’s purposive activity is transferred to natural selection, seen as a purposive agent (Chapter 19).

My larger argument in this book will be that the biologist’s conscious commitment to purely physical and chemical descriptions — which is to say, her conscious refusal of much that she actually knows — has devastating effects upon many fields of biological understanding, and particularly evolutionary theory. It hardly needs emphasizing that if organisms really are purposive beings — if the fact of purposive activity is not an illusion — then a biological science so repulsed by the idea of purpose that its practitioners must avert their eyes at the very mention of it … well, it appears that these practitioners must feel threatened at a place they consider foundational. And with some justification, for to admit what they actually know about organisms would be to turn upside down and inside out much of the science to which they have committed their lives.

“Purpose” — an idea that will need careful qualification in different biological contexts — gives us but one of several intimately related avenues of approach to what is distinctive about the life of organisms. In the remainder of this chapter I will briefly sketch a few of these avenues.

Organisms are agents capable of
pursuing their own meanings

Organisms are agents; they do things. The difference between a motionless rock, on one hand, and a motionless cat on the other is that the cat is not merely motionless; it is resting, or perhaps preparing to pounce. When it ceases doing things, it is no longer alive. Whereas a rock may be moved by impinging forces, the cat itself moves. In our routine experience we take self-motivated activity to be definitive of living things. If an object moves unexpectedly — without an evident external cause — we immediately begin testing the assumption that it is living.

When an animal responds to a physical stimulus, its response is not in any strict way physically enforced, or directly caused, by the stimulus. Rather, the animal “reads” the meaning of the situation in light of its own concerns, including its needs and interests, and then alters that meaning by responding to it. If the animal is physically moved by a stimulus, as when a rolling stone bumps into a leg, we don’t consider the movement to be the organism’s own act. It is not a response, but merely a physically caused result.

As a useful picture of this, we need only consider how the negligible force producing an image on the retina — say, the image of a charging lion — can set the entire mass of a quarter-ton wildebeest into thundering motion. The impelling force comes from within, so that the movement seems to originate within the animal itself in a way that we do not see in inanimate objects.

The wildebeest is not forcibly moved by a physical impact, but rather perceives something. Further, its perception is at the same time an interpretation of its surroundings from its own point of view and in light of its own world of meaning. The “lawfulness” at issue here, such as it is, is far from being universal. It differs radically from one living being to another, so that the retinal image of a charging lion means a very different thing to the wildebeest from what it means to another lion or to a vulture circling overhead. And it produces an altogether different response in these cases.

All this may seem trivially obvious — and so it is. We make sense of biological activity in terms of meanings radically different from the meanings we bring to inanimate events. But this only renders more poignant biologists’ futile desire to pursue their explanatory tasks as if there were no such radical distinction between the animate and inanimate.

Nevertheless, we all find it difficult to conceal or deny what we know. So despite the biologist’s attempted disavowal of what is distinctively biological in her science, the truth comes out in a thousand ways, and above all in the choice of language. The words employed for description of animate activity differ dramatically from those applied to inanimate activity.

Think, for example, of a living dog, then of its decomposing corpse. At the moment of death, all the living processes normally studied by the biologist rapidly disintegrate. The corpse remains subject to the same laws of inanimate nature as the live dog. But now, with the cessation of life, we see those laws strictly in their own terms, without reference to life. The dramatic change in our descriptive language as we move between the living and the dead speaks more loudly than any philosophical convictions we may have about life and death.

No biologist who had been studying the behavior of the living dog will concern herself with the corpse’s “behavior”. Nor will she refer to certain physical changes in the corpse as reflexes, just as she will never mention the corpse’s responses to stimuli, or the functions of its organs, or the processes of development being undergone by the decomposing tissues.

Virtually the same collection of molecules exists in the canine cells during the moments immediately before and after death. But after the fateful transition no one will any longer think of genes as being regulated, nor will anyone refer to normal or proper chromosome functioning. No molecules will be said to guide other molecules to specific targets, and no molecules will be carrying signals, which is just as well because there will be no structures recognizing signals. Code, information, and communication, in their biological sense, will have disappeared from the scientist’s vocabulary.

The corpse will not produce errors in chromosome replication or in any other processes, and neither will it attempt error correction or the repair of damaged parts. More generally, the ideas of injury and healing will be absent. No structures will inherit features from parent structures in the way that daughter cells inherit traits or tendencies from their parents, and no one will cite the plasticity or context-dependence of the corpse’s adaptation to its environment.

The language highlighted here is clearly a language of more-than-physical meaning. When investigators do their best to ignore these additional layers of meaning — for example, when they present their findings as if everything were “naturalistic”, or as if their task were merely to elucidate physical and chemical interactions — then they are contradicting just about all their own biological descriptions.

It is not that such researches are inadequate in their own, limited terms. We can be sure that everything being described makes perfect sense, and that the physical picture reveals no mysterious gaps. It’s just that, within the arbitrarily imposed limits of physical and chemical description, we will see no living activity. The “naturalistic” presentations characterize only those aspects of the animal’s body that continue uninterrupted, according to exactly the same laws, when it dies. If we restricted our understanding to this characterization, death would not even be a recognizable event.

Of course, in a split-personality sort of way every biologist does recognize death, because she recognizes the distinctive sorts of meaning, including the perceptions, purposes, intentions, and responses, that the once-living dog is no longer expressing. It’s just that she typically refuses to let the expressive aspects of the creature’s life become uncomfortably explicit, or to influence fundamental theory. Or, when they do affect theory, it must be the organism’s physical activity, not its interior life as a perceptive and intentional actor, that enters into scientific consideration. Like the behaviorists of old, we are forbidden to accept the inner, immaterial, and immediately given reality of perceptions and intentions, as opposed to various associated physical manifestations.

The end is more constant than
the means of attaining it

William McDougall, who lived from 1871 to 1938, was a highly respected (if also rather controversial) British psychologist who, after teaching at Oxford, spent the latter part of his career in the United States. He authored widely used textbooks of psychology and, for several years, occupied William James’ chair at Harvard. Then he moved to Duke University where, with J. B. Rhine, he founded the Parapsychology Laboratory. Our present interest, however, is in a 1929 work, where McDougall usefully summarized certain typical features of purposive activity (McDougall 1929, pp. 50-1). He was writing about human behavior, but we can recognize these features in all purposive behavior, conscious or otherwise:

• Goal-directed activity tends to be persistent and may be repeatedly renewed even after being effectively blocked for a time. If you tie up your hungry dog at some distance from its food bowl, it may cease straining at the leash. But as soon as you grant it freedom, it will again head for the bowl.

• Goal-directed activity is very often adaptable to one degree or another. If one strategy fails, the organism may vary it or switch to a different strategy. As many dog owners have discovered after forgetting to give Fido his food, their beloved pet may contrive a means to enjoy the freshly roasted chicken on the kitchen counter.

• And, as soon as the goal is reached, that particular goal-directed activity ceases. Having had its fill, your dog may want to play or else to sleep. But it will not continue its quest for food.

We do not find the same combination of features in the inanimate world. Yet anyone who interacts with animals takes them for granted. Moreover, analogous features are evident even in physiological activity, all the way down to the molecular biology of the cell. In its development “the embryo seems to be resolved to acquire a certain form and structure, and to be capable of overcoming very great obstacles placed in its path”. When encountering such an obstacle to its development, the organism “adjusts itself to the changed conditions, and, in virtue of some obscure directive power, sets itself once more upon the road to its goal; which under the altered conditions it achieves only by means of steps that are different, sometimes extremely different, from the normal” (McDougall 1911, pp. 242-3).

When a cell is preparing to divide, it passes through what are known as internal “checkpoints”, where the cell responds to the presence or absence of conditions necessary for a successful division. If something is awry, the cell may persist in the aim of dividing by taking any corrective (adaptive) action that happens to be within its power. It then proceeds with its division, and ceases the entire, highly coordinated and complex activity once the process is complete. (And when division is inadvisable — say, because chromosomes have been irreversibly damaged too badly — the cell may proceed toward a larger end, whereby its distinct existence ceases and its resources are offered up to the rest of the organism of which it is a part.)

No one will bristle upon hearing that “this cell is preparing to divide”. But we would certainly bristle if we heard that “Mars is preparing to make another journey around the sun”, or “the nebula has ceased its effort after forming the solar system”. A planet moves according to universal laws acting in an unchanging manner. There is no point in its journey when an act is initiated or concluded, but only the playing out of the immediately preceding forces. There is in this sense nothing new to explain. Biological explanation, by contrast, always involves something new, an element of initiative, a response to circumstances not fully necessitated by the preceding play of physical and chemical processes.

Here’s another illustration, drawn from the great English physiologist, Sir Charles Scott Sherrington, writing in 1922. He is talking about what happens when, in some animals, a motor nerve is severed and the portion running from the point of severance to the muscle dies. The living end of the nerve immediately embarks upon a meaningful and unfathomably complex journey:

The fibre, so to say, tries to grow out to reach to its old far-distant muscle. There are difficulties in its way. A multitude of non-nervous repair cells growing in the wound spin scar tissue across the new fibre’s path. Between these alien cells the new nerve-fibre threads a tortuous way, avoiding and never joining any of them. This obstruction it may take many days to traverse. Then it reaches a region where the sheath-cells of the old dead nerve-fibres lie altered beyond ordinary recognition. But the growing fibre recognises them. Tunnelling through endless chains of them, it arrives finally, after weeks or months, at the wasted muscle-fibres which seem to have been its goal, for it connects with them at once. It pierces their covering membranes and re-forms with their substance junctions of characteristic pattern resembling the original that had died weeks or months before. Then its growth ceases, abruptly, as it began, and the wasted muscle recovers and the lost function is restored.6

Here we see again goal-directed persistence over a long period, adaptability in the face of obstacles, and cessation of this particular activity when its end is achieved.

Notice also Sherrington’s careful caveat (“so to say”) whereby he qualifies the easily anthropomorphized phrase, “tries to grow”. The care and the qualification are fully justified. But the fact is that such phrasing is pervasive and seemingly unavoidable whenever the researcher would offer informative biological descriptions. This suggests that we owe it to the discipline of biology to explore the nature of our own usage. It pays to know what we are really saying, rather than leaving it in a vague and ambiguous cloud of suggestion. Throughout this book we will touch on some of the problems we run into when employing the language of purposiveness, goals, and intentions.

E. S. Russell, a British marine biologist whose writings during the first half of the twentieth century can sometimes seem more up-to-date regarding the decisive issues of twenty-first century biology than the literature of our own day, summarized the gist of the foregoing discussion with wonderful succinctness: “The end-state is more constant than the method of reaching it” (Russell 1945, p. 110). This suggests that the end-state, understood as somehow implicit in the entire drama leading up to it, plays something like a causal role. This would be similar to the way a well-considered conclusion is implicit in the profound, multivalent play of thought leading up to it, rather than being the mere passive outcome of a deterministic march of machine logic. (For a fuller treatment of this, see Chapter 12, “Form and Cause in Biology”.)

Surely any such causal dimensions involving end-states would have large implications for a science determined to unravel physical and chemical means while pretending to ignore the ends that express the meaning of the activity.

Every organism is narrating
a meaningful life story

The fact of purposive activity — the obvious play of active agency; the coordination of diverse means toward the realization of countless interwoven and relatively stable ends; the undeniable evidence that animals perceive a world, interpreting and responding to perceptions according to their own way of life; and the coherence of all this activity in a governing unity — all this tell us that every organism is narrating a meaningful life story. This is not something that a rock, say, loosened by ice and tumbling down the steep slope of a mountain ravine, does in anything like the same manner. The pattern of physical events in the organism is raised by its peculiar sort of coherence toward something like a biography whose “logic” unfolds on an entirely different level from the logic of inanimate physical causation. When we tell a story, the narrative threads convey meanings — for example, motives, needs, and intentions — and these are never a matter of mere physical cause and consequence.

So when I speak of the organism’s wise and knowing agency, or its purposive striving, I refer, among other things, to its capacity to weave, out of the resources of its own life, the kind of biological narrative we routinely observe, with its orchestration of physical events in the service of the organism’s own meanings.

We normally feel every birth as a new beginning, full of hope and expectation — a beginning of a sort we do not experience in the genesis of a raindrop or dust devil. Even the first shoot of a bean or squash seed, pushing upward through the soil surface, is the prelude to a narrative promising many vicissitudes — engagements with insects and diseases, complex communal relations with other plants, and confrontations with nurturing or threatening forces of nature. And a death is always the end of a story.

Box 2.1

The Nesting Cycle of the Chaffinch

chaffinches and their nest

From a 1927 description by the British naturalist and ornithologist, Edward Max Nicholson:7

“The male must leave the flock, if he has belonged to one, and establish himself in a territory which may at the time be incapable of sustaining him alone, but must later in the season supply a satisfactory food-supply for himself, his mate and family, and for as many birds of other species as overlap his sphere of influence. He must then sing loudly and incessantly for several months, since, however soon he secures a mate, trespassers must be warned off the territory, or, if they ignore his warning, driven out.

“His mate must help with the defence of the territory when she is needed; pairing must be accomplished; a suitable site must be found for the nest; materials must be collected and put together securely enough to hold five bulky young birds; eggs must be laid in the nest and continuously brooded for a fortnight till they hatch, often in very adverse weather; the young are at first so delicate that they have to be brooded and encouraged to sleep a great part of the time, yet they must have their own weight of food in a day, and in proportion as the need of brooding them decreases, their appetites grow, until in the end the parents are feeding four or five helpless birds equal to themselves in size and appetite but incapable of digesting nearly such a wide diet.

“Enemies must be watched for and the nest defended and kept clean. When the young scatter, often before they can fly properly, they need even greater vigilance, but within a few days of the fledging of the first brood a second nest will (in many cases) be ready and the process in full swing over again. All this has to be done in face of great practical difficulties by two creatures, with little strength and not much intelligence, both of whom may have been hatched only the season before.”

E. S. Russell, commenting on descriptions such as those of the chaffinch in Box 2.1, noted the narrative connectedness of the events: “Behaviour is often part of a long-range cycle of events, in which one action prepares for and leads on to the next until the end term is reached. Each stage in the chain or cycle is unintelligible to us except in its relation to what has gone before, and, more particularly, to what is yet to come. Such cycles have a temporal unity …” (Russell 1938, pp. 7-8). Present significances are interwoven with and inseparable from the tapestry of past events and their meanings. And future developments, along with whatever new and unpredictable elements they bring, are a continued, improvisational elaboration of the same tapestry of meaning.

In other words, the “end” being approached in an organism’s story is not some particular, discrete accomplishment, distinct from the means of getting there, but rather the wholeness and perfection of the entire narrative movement from “here” to “there”. Assessing this end is much the same as if we were assessing the meaning of a novel: knowing the ending in isolation would have little significance compared to knowing the larger story of which it is part.

I offer no specific hypotheses to explain the existence of intentional agency and story narration. I only note that the fact of the narrative is immediately demonstrable in every organism. There may be huge differences in the nature of the stories that can be told by different sorts of organism, but from the molecular level on up there are always elements of story that we do not find in inanimate things. The narrative of goal-oriented activities undertaken and accomplished is there to be seen, and is characterized as such, if only inadvertently, in every paragraph of biological description.

Moreover, our recognition of intelligent and intentional activity does not require us to understand its source. Looking at the pages of a book, we have no difficulty distinguishing written marks from deposits of lint and dust, even if we know nothing about the origin of the marks. We can declare a functioning machine to be engaged in a purposive operation, whether or not we have any clue about the engineers who built a mechanistic reflection of their own purposes into it. And if we find live, intelligent performances by organisms, we don’t have to know how, or from where, the intelligence gets its foothold before we accept the testimony of our eyes and understanding.

Neither should we expect the stories to be predictable — no more than we expect the ending of a half-read novel to be predictable. We can, however, expect the ending to make sense, and even to throw light on everything that went before. The story will hold together in a way that unstoried physical events do not.

The storytelling is the
being of the organism

If the organism’s life is an unfolding story, then we might well take the essence of that life to be the storytelling itself, not the particular embodiment of the story at any frozen instant. Organisms, as philosopher Hans Jonas has written, “are individuals whose being is their own doing … they are committed to keeping up this being by ever renewed acts of it.” Their identity is “not the inert one of a permanent substratum, but the self-created one of continuous performance” (Jonas 1968, p. 236, 233). Or, as Spinoza put it a few centuries earlier:

The effort by which each thing endeavors to persist in its own being is nothing else than the actual essence of the thing itself.8

Or, again, we have the rather different formulation by Paul Weiss, a National Medal of Science recipient and profound observer of cellular life:

Life is a dynamic process. Logically, the elements of a process can be only elementary processes, and not elementary particles or any other static units. (Weiss 1962, p. 3)

An organism is not, most essentially, its body. It is a unique power of activity. Its body is, first of all, a result of this activity, while also developing into a further vehicle for it. Organisms, in other words, are doings rather than beings. Or, as the student of holistic thinking, Henri Bortoft, has put it, they are “doings that be”, not “beings that do”.9 So it is not that an organism’s material being determines its doings (as is broadly assumed throughout the biological sciences); rather, its doings are what constitute it as a material being. This means that it is never wholly present to our observation in any outward or material sense. The organism’s essential power to act cannot itself be a visible product of its activity.

The preeminence of activity in relation to physical substance and structure would, if taken seriously, give us an altogether new science of life. For example, it might have saved us from an entire century of badly misdirected thinking about DNA and genes. It might also have spared biologists the crude materialism that many physicists long ago gained the freedom to question.

But this is to get ahead of the story. For now, it is enough to mention two questions implicit in the foregoing, while deferring further comment:

Regarding our theory of evolution: If, in reality, every organism’s existence is a live, moment-by-moment, improvisational storytelling — a creative and adaptive, irreversible narrative that is always progressing coherently and contextually from challenge to response and adaptation, from initiative to outcome, from nascence to renascence, from immaturity through maturity to regeneration — then an evolutionary theory rooted in notions of random variation and mindlessness is a theory hanging upon a great question mark. “The answer to the question of what status teleology should have in biology” — so the influential biologist and philosopher Francisco Varela came to see at the end of his life — determines “the character of our whole theory of animate nature” (Weber and Varela 2002).

And then there is the question whether the future of individual species, the future of particular ecological settings, the future of life’s diversity on earth, and the future of earth itself, all depend on our willingness and ability to attend to the life stories of the beings among whom we live — depend, finally, on our capacity for the reverence that these stories so naturally evoke.

rule

There are many issues raised by the discussion in this chapter. For example:

• What is the relation between the purposes of organisms in general and our own conscious purposes?

• Can we reasonably say that animals, and especially the simplest animals, possess a form of consciousness?

• How do conscious human purposes relate to the purposiveness in our bodies and cells, through which many of our intentions are carried out?

And much more. We will find ourselves engaging such questions in later chapters.
