In a world of ever-growing specialization, the issue of complexity attracts a good amount of attention from cross-disciplinary points of view. Charles S. Peirce’s thought may help not only to shoulder once again philosophical responsibility which has been largely abdicated by much of 20th century philosophy, but also to tackle some of the most stubborn contemporary problems. The founder of pragmatism identified one century ago most of these problems, and he also mapped out some paths that may be followed to overcome the poverty of contemporary scientistic reductionism. One of these paths is related with the issue of complexity that lies at the heart of all his conception.
Along this line, the aim of this article is to describe what Peirce can teach about complexity to contemporary researchers from different scientific backgrounds. The article is divided in three sections: 1) a brief presentation of Peirce, stressing his personal authority as a scientist philosopher; 2) the theory of categories as the heart of complexity according to Peirce and, finally, 3) some consequences of Peirce’s notion of complexity in relation with abduction and creativity, semiosis, cross-disciplinarity and communication.

Peirce’s thought may help not only to shoulder once again philosophical responsibility which has been largely abdicated by much of 20th century philosophy, but also to tackle some of the most stubborn contemporary problems (Debrock, 1992, p.1). The founder of pragmatism identified one century ago most of these problems, and he also mapped out some paths that might be followed to overcome the poverty of contemporary scientistic reductionism. One of these paths is related with the issue of complexity that lies at the heart of all his conception.

The influence and the relevance of the work of Charles S. Peirce for very different areas of knowledge is increasingly being recognized (Fisch, 1980; Wright, 1993, p.41): in astronomy, metrology, geodesy, mathematics, logic, philosophy, theory and history of science, semiotics, linguistics, econometrics, and psychology. In all these fields Peirce has been considered a pioneer, a forerunner or even a ‘father’ or ‘founder’ (of semiotics, of pragmatism). Superlative evaluations of his contribution are not uncommon. Thus, Russell states that “beyond doubt … he was one of the most original minds of the later nineteenth century, and certainly the greatest American thinker ever” (Russell, 1959, p.276). Similar quotations may be found in the work of Umberto Eco (Eco, 1989, p.x-xi), Karl Popper (Popper, 1972, p.212), Hilary Putnam (Putnam, 1990, p.252), and many others.
Among the major factors that have furthered the growing interest in Peirce’s thought are his personal participation in the scientific community of his time, his valuable contribution to the logic of relatives, and his sound knowledge of the philosophy of Kant as well as of the Scholastic tradition, in particular Duns Scotus’ philosophy. Thus Peirce has been considered not only a forerunner of contemporary analytic philosophy (Hookway, 1985, p.141; Wright 1993: 41), but also as a milestone in the semiotic transformation of transcendental philosophy (Apel, 1981), and even as a renovator of the Aristotelian tradition which played a central role in the development of Western philosophy (Beuchot & Deely, 1995; Gracia, 1993).
All of this is commonplace in the present revival of the scholarship on Peirce. The point I want to stress, however, is that, though Charles S. Peirce was a philosopher and a logician, he was first and foremost a real practitioner of science. Not only was he trained as a chemist at Harvard, but for thirty years (1861-91) he worked regularly and strenuously for the U. S. Coast Survey as a metrologist and as an observer in astronomy and geodesy. His reports to the Coast Survey are an outstanding testimony to his personal experience in the real hard work of measuring and obtaining empirical evidence. A glance at his official reports to the Coast Survey or at his Photometric Researches produced in the years 1872-75 immediately confirms the impression of a man involved in solid scientific work (W 3: 382-493, 1878). As Max Fisch points out, “Peirce was not merely a philosopher or a logician who had read up on science. He was a full-fledged professional scientist, who carried into all his work the concerns of the philosopher and logician” (W 3: xxviii-xxix).
It was on the basis of his experiences as a young scientist that Peirce came to believe that the community of inquirers was essential for scientific rationality. For him, science can flourish only in the context of research communities: the pursuit of truth is a corporate task and not an individual search for foundations. As Peirce wrote in The Ethics of Terminology, “the progress of science cannot go far except by collaboration; or, to speak more accurately, no mind can take one step without the aid of other minds.” (CP 2.220, 1903). This communitarian perspective upon scientific activity, as Bernstein remarked, “not only challenges the characteristic Cartesian appeal to foundations, but adumbrates an alternative understanding of scientific knowledge without such foundations” (Bernstein, 1983, p.71-72).
The interpretation of Peirce’s thought and its evolution from his early writings in 1865 until his death, for many years provoked wide disagreement amongst Peirce scholars. This was due in part to the fragmentary presentation of his work in the Collected Papers, and in part to his going against the grain. The fact is that, as a philosopher, Peirce is not easily pigeon-holed: Some considered him a systematic thinker, but with four successive systems (Murphey, 1961); others saw him as a contradictory thinker (Goudge, 1950; Rorty, 1996)2 or as a speculative metaphysician of an idealist type (Esposito, 1980). In recent years, however, a deeper understanding of the architectonic nature of his thought and of his whole evolution has been gaining general acceptance (Hausman, 1993, p.xiv-xv; Houser 1992, p.xxix). In the last decade all Peircean scholars have clearly acknowledged the basic coherence and undeniable systematic unity of his thought (Santaella-Braga, 1993, p.401; Hausman, 1993; Parker, 1998).
Following Hookway to some extent (Hookway, 1985, p.1-3), I think that the most accurate understanding of Peirce is to see him as a traditional and systematic philosopher, but one deals with the modern problems of science, truth and knowledge from a very valuable personal experience as a logician and as an experimental researcher in the bosom of an international community of scientists and thinkers. In this sense, Peirce’s personal participation in the scientific community of his time buttresses whatever he has to say about complexity from a philosophical point of view.
There is not yet a unified conception of complexity, nor, as Roberta Kevelson put it, “a common ground or a general unifying and synthesizing notion of complexity which can act as a referential principle for all various approaches” (Kevelson, 1993, p.265). Hoping that maybe Peirce might offer some suggestions, I searched the electronic version of Peirce’s Collected Papers for the term ‘complexity’. To my surprise, a great deal of the 40 occurrences of the term “complexity” concerned protoplasm and the chemical complexity of its molecules (CP 1.393, c.1890; 6.246, 1891; 6.278, 1893; 6.283, 1893; 7.503, 1898; 1.351, c.1905). This fact strongly suggested to me that for Peirce complexity is in the first place related to the structure of the world, and only secondarily to our ways of understanding it and talking about it:
Though the term ‘protoplasm’ had been introduced by von Mohl in 1848, it had gained widespread acceptance under the influence of Huxley; and by the time of Peirce’s writing, the study of the structure of protoplasm “the living substance of the cell, exclusive of the nucleus”, had become the center of biological research and scientific debate (Baldwin, 1901, II, p.372). To Peirce, the chemist, the complexity of the protoplasm molecule was nothing less than “amazing” (CP 1.393, c.1890):
The typical properties of the protoplasm, “contractility, irritability, automatism, nutrition, metabolism, respiration, and reproduction […] can all be summed up under the heads of sensibility, motion, and growth” (CP 1.393, 1887-88). For Peirce these can not possibly be fully explained or understood under the reductionist paradigm of mechanical physics, which does not allow us to fathom the phenomena of growth and increasing complexity:
And in another place, some years later (CP 1.174, 1905):
Even more amazing perhaps is the fact that Peirce considers the properties of protoplasm to be instrumental in our understanding of psychical activity, as the last words of the second quotation above already suggest: “the laws of nervous action are, as I think, traceable to the chemical characters of the protoplasms of which the contents of nerve-cells are composed” (CP 6.278, 1893).3
This approach was fully developed by Peirce in his manuscript “A Guess at the Riddle” of 1887-88, which “is perhaps Peirce’s greatest and most original contribution to speculative philosophy” (EP 2: 245). In that paper Peirce described the three irreducible categories, which he originally derived from his logical studies, and later applied to all phenomena. In “A Guess at the Riddle” he illustrates the application of that triad to metaphysics, psychology, physiology, biology development, and physics.
This is one of the central points of Peirce’s views on complexity, which is also relevant to contemporary theories of mind and which reflects very well the naturalistic flavor of Peirce’s revolt against Cartesian dualism typical of modern philosophy. Peirce’s questioning of certain Cartesian assumptions and methodology is —according to Dipert (1999, p.2)— “Peirce’s earliest major contribution to the philosophy of mind”. His attempt to illustrate the nature and qualities of our mental activity by the properties of the protoplasm of the nerve-cells may be compared to some research programs which try to explain what we human beings are by way of deciphering the genetic language of the chromosomes (Searls, 1992; Eberling & Jiménez-Montaño, 1980), or to some contemporary trends of functionalism in philosophy of mind in which attempts are made to understand our brains as sophisticated computers (Putnam, 1988; Searle, 1992). But the essential difference between Peirce’s approach and these contemporary trends is that Peirce never tries to reduce complex phenomena to simpler ones, to a set of fundamental mechanical laws, but on the contrary he understands all phenomena in terms of the most general categories that an attentive study of experience yields. This is the essential point Peirce has taught us, as has been emphasized by the new physics (Anderson, 1972; Arecchi & Farini, 1996) or by the late novelist Walker Percy in his memorable Jefferson Lecture(Percy, 1989).
In order to understand Peirce, it is necessary to deal with his three fundamental categories: Firstness, Secondness, and Thirdness, that are the core of his theory. Speaking of Firstness, Secondness, and Thirdness may sound as meaningless and unpalatable gibberish of a metaphysico-mathematical stripe, but not only it is impossible to make sense of Peirce without them, but, moreover, these three categories were indeed Peirce’s gift to the world (Debrock, 1996).
The easiest access to the categories is by way of experience. All we need is to simply look at how phenomena appear. This is exactly what Peirce suggested by his choice of the word ‘Phaneroscopy’ (from the Greek words ‘to faneron’, which is synonymous to ‘phenomenon’ and ‘skopein’ which means ‘to look at’). Such phaneroscopy “shows that the formal relations studied in mathematical logic have material correlates in experience” (Parker, 1998, p.105). Let us take an example of my feeling the solid surface of this desk: as feeling, it involves reactivity, opposition, and thus secondness. But how the two elements are related to each other so that there is the object which I call this desk, is a matter which Peirce calls thirdness. On the other hand, since secondness somehow presupposes that there are two elements involved, each of which is distinct from the other, the phaneroscopy must admit of Firstness which, in virtue of its sheer singleness is the most difficult aspect to describe:
In 1905, Peirce traced back the discovery of the three categories “after three years of almost insanely concentrated thought” to his paper of 1867, “On a New List of Categories”. He summarizes his discovery of the categories as follows: “I examine the phaneron and I endeavour to sort out its elements according to the complexity of their structure. I thus reach my three categories”. (CP 8.213, c.1905).
Charles Hartshorne and Paul Weiss organized a section of the first volume of Peirce’s Collected Papers under the title “Protoplasm and the Categories”, with three paragraphs of his Logic Notebook II of around 1905, where he explains how the three categories obtained from mathematics may be helpful in our understanding the function of protoplasm:
And this explanation concludes with the assertion that these categories
The naturalistic tendency of Peirce’s mature thought is unmistakable. In Houser’s words, he “had come to believe that attunement to nature was the key to the advancement of knowledge, as it was for life itself” (Houser, 1998, pp.xxxii-xxxiii). But he can not be considered a “reductionist”, whether it be in the materialist or in the idealist sense. Indeed, Peirce rejected both materialism and idealism: “the former makes the laws of mind a special result of the laws of matter, while the latter makes the laws of matter a special result of the laws of mind” (CTN 1, p.200, 1893). Instead, he stressed the continuity between matter and mind:
Peirce’s reflections on continuity stem from mathematics and geometry, but he extended the principle of continuity to the human mind and the universe, as a reply to the inadequacy of mechanicist scientific explanations: “the universe is not a mere mechanical result of the operation of blind law. The most obvious of all its characters cannot be so explained. It is the multitudinous facts of all experience that show us this” (CP 1.162, c.1897). For Peirce, materialist explanations cannot account for the experienced mental realities of intention, purpose, and feeling, nor can they satisfactorily account for the irreversibility of phenomena of “degradation of energy” described in the second law of thermodynamics (Parker, 1998, p.201). Not reduction, but continuity is the key notion which makes Peirce our contemporary in our attempt to understand complexity:
For Peirce, all phenomena of our experience, all actual events involve the three elements, the three categories which are inherently and utterly irreducible to each other. The categories
Of the most important characteristics of thirdness is that, according to Peirce, thirdness is always related to habit taking which is essentially a continuous process. Thus, characteristically, Peirce points out that “it seems to be a universal property of protoplasm [which is one of the simplest natural expressions of complexity], intimately connected with the property of growth, that it takes habits” (CP 6.280, 1893). No wonder then that the same should apply to complexity as it appears in all the forms of human experience, even in its simplest forms. This may explain why mechanicism which tries to explain natural phenomena in terms of rigid laws, is totally incapable of dealing with the continuity between mind and matter (CP 1.162, c.1897), which is so deeply characteristic of our daily experience, of the communication between human beings, and of growth in every sense, but specially in the sense of a process of habit forming and learning.
Ilya Prigogine has credited Peirce’s view of time and of the second law of thermodynamics with being a remarkable anticipation of the new physics. He stated that “Peirce’s metaphysics was considered as one more example of philosophy alienated from reality […]. Today, Peirce’s work appears a pioneering step toward understanding the pluralism involved in physical laws” (Prigogine & Stengers, 1987, pp.302-303; Brent, 1998, pp.175-176). Kevelson writes that Prigogine “is thoroughly Peircean when he speaks of a new attitude in science’s description of the natural world” (Kevelson, 1993, p.284). For his part, Ian Hacking considers Peirce as a thinker with a very advanced position in respect to the issue of indeterminism, and also a pioneer on the metaphysical level on the turn of the century (Hacking, 1990). But instead of pursuing the topic of Peirce’s anticipation of contemporary physics, the attention will be turned to some consequences of Peirce’s approach to complexity in other areas of great interest: 1) abduction and creativity, 2) semiosis, and 3) cross-disciplinarity and communication.
One of Peirce’s most original contributions was his introduction of abduction or retroduction as a third mode of inference besides the two traditionally recognized methods of deduction and induction. Abduction is the process by which we engender new ideas, explanatory hypotheses and theories, both in the field of science and in everyday life (Génova, 1997). “Abduction”, writes Barrena, “is a reasoning by hypothesis, that is, a reasoning by means of an explanation which arises spontaneously upon considering that which in each circumstance has surprised us” (Barrena, 1996, p.33). Abduction is the key to innovation. It starts from facts and broadens our knowledge by means of explanatory theories. Abduction is not merely a “logical operation”, but it is rather, from a semiotic point of view, that spontaneous activity of the mind which makes the strange familiar. Here is one of Peirce’s examples,
The whiteness of the animal is not in any way complicated, but it breaks our expectations and demands an explanation. Our spontaneous abduction consists of taming the anomalous fact that surprises by formulating some possible assumption from which the fact could be derived. Our abductive reasoning is continuous with nature’s logic by virtue of which novelty enters the world (Anderson, 1987, p.50).
The three categories of Firstness, Secondness, and Thirdness correspond respectively to the basic triadic classification of signs into qualisigns, sinsigns and legisigns. James Liszka has argued convincingly that a Peircean sign theory can offer a unique solution to the problem of how meanings are generated. The theory suggests that “complexity and sign formation are integral. Put as a thesis, the argument is that the very conditions required for complexity happen to be those conditions Peirce articulates as formative of a sign” (Liszka, 1999, p.313; 1998). That theory makes sense of the processes where meaning is generated, while staying within a framework which is both naturalistic and non-dualistic:
Something in the same vein was argued tentatively by Walker Percy in his theory of language, and very recently by Floyd Merrell (Merrell, 1998, p.284). According to Percy, if we follow the lines sketched by Peirce, it is possible to gain a proper understanding of the articulation of thought and world in language, because meaning only emerges within the interaction of these three elements: thought, language and world. When a two-year-old child looks at a flower and babbles “flo-wa”, he is coupling in his conduct the flower, the sound, his mother as the addressee of the expression, and himself as the builder of the coupling. The complexity of this habitual communicative process cannot be explained dyadically. For any dyadic explanation of communication denatures the process and thus makes real understanding impossible (Percy, 1989, p.86; Nubiola, 1998).
There is a trend in evolutionary theory and sociobiology according to which the human mind is believed to have evolved as a means of coping with environmental complexity (Godfrey-Smith, 1996; Maclaurin, 1998). This might be called a pragmatist thesis, the source of which may be traced back to Spencer and Dewey, but not properly speaking to Peirce. For Peirce the main evolutionary force is not adaptation, but love. Perhaps that sounds strange to our positivistic ears, but in Peirce’s paper of 1893 entitled precisely “Evolutionary Love” he explains his doctrine of agapism, the doctrine that love is operative in the world (EP 1: 352; Hausman 1974).
For this reason, the main lesson to learn from Peirce about complexity in the present world of super-specialization is perhaps to listen to each other, in spite of different backgrounds and specialties, trying to learn from everybody, because “growth comes only from love” (CP 6.289, 1891). A long quotation from a manuscript of 1905 may very well provide with the Peircean key which may be needed to further pursue research on complexity:
As Wible writes, “complexity theory is creating a new vision of science” (Wible 2000, p.25). In the present landscape of scientific research Peirce’s approach to complexity makes possible not only to overcome the reductionistic bias of twentieth-century positivism, but even the individualistic and competing atmosphere that pervades the communities of research.5

In a long conversation in Stanford in August 1996 Rorty told me that he had “wasted” the first two years of his professional life as a philosopher trying unsuccessfully to make sense of Peirce’s thought, and that he had given up his effort after reading Murphey’s book. In spite of that comment, the young Rorty was the first philosopher to acknowledge the similarities between Peirce and the last Wittgenstein (Rorty 1961; Nubiola 1996: 281). ↩︎
