Lately I’ve had the poor judgment to start reading Heidegger’s Being and Time. I’ve been putting it off for years now, largely because it has no connection with the kind of philosophy I’m interested in. Yet, among my philosophical acquaintances there is a clear line between those who have read Heidegger and those who haven’t—working through this book really does seem to let people reach a whole new level of abstraction.
To my great surprise, in Being and Time (1927: 413), Heidegger remarks:
[E]ven that which is ready-to-hand can be made a theme for scientific investigation and determination… The context of equipment that is ready-to-hand in an everyday manner, its historical emergence and utilization, and its factical role in Dasein — all these are objects for the science of economics. The ready-to-hand can become the ‘Object’ of science without having to lose its character as equipment. A modification of our understanding of Being does not seem to be necessarily constitutive for the genesis of the theoretical attitude ‘towards Things’.
Curiously, no other sources I’ve found mention this excerpt. More well-known is a passage from “What are Poets for?” in which Heidegger denounces marketization (1946: 114-5):
In place of all the world-content of things that was formerly perceived and used to grant freely of itself, the object-character of technological dominion spreads itself over the earth ever more quickly, ruthlessly, and completely. Not only does it establish all things as producible in the process of production; it also delivers the products of production by means of the market. In self-assertive production, the humanness of man and the thingness of things dissolve into the calculated market value of a market which not only spans the whole earth as a world market, but also, as the will to will, trades in the nature of Being and thus subjects all beings to the trade of a calculation that dominates most tenaciously in those areas where there is no need of numbers.
Thus it’s very easy to appeal to Heidegger’s authority to support various Leftist clichés about capitalism. It’s far harder to bring Heidegger’s thought to bear on actual economic modelling—its ‘worldly philosophy’. In this post I’ll survey several of the less hand-wavey attempts in this direction. My main question is whether a Heideggerian economics is possible at all, and if so, whether there is a specific subfield of economics to which Heideggerian philosophy especially lends itself. My overview of each specific thinker sticks closely to the source material, as I’m hardly fluent enough in Heideggerese to give a synoptic overview or clever reinterpretation. I don’t expect to ever develop a systematic interpretation of my own, but I hope this post might prove inspiring to some economist with philosophical tastes far different from my own.
1. Schalow on ‘The Question of Economics’
Schalow’s approach is quite refreshing because he is both an orthodox Heideggerian and takes the viewpoint of mainstream economics, as opposed to Heideggerian Marxism such as Marcuse’s One-Dimensional Man. Schalow’s question is at once simpler and deeper: whether Heidegger’s thought leaves any room for economics. Here, ‘economics’ is minimally defined as theorizing the production and distribution of goods to meet human needs. (So in theory, then, this applies to any sort of economics, classical or modern.) The most obvious answer would seem to be ‘No’ — he notes: “It is clear that Heidegger refrains from ‘theorizing’ of any kind, which for him constitutes a form of metaphysical rationality” (p. 249).
Thus, Schalow takes a more abstract route, viewing economics simply as “an inescapable concern of human being (Dasein) who is temporally and spatially situated within the world” (p. 250). Schalow advocates a form of ‘chrono-economics’, where ‘scarcity’ is framed through time as numeraire. In a sense, this operates between ‘economic theory’ as a mathematical science vs. as a “humanistic recipe for achieving social justice” (p. 251); instead, “economic concerns are an extension of human finitude” (p. 250). Schalow makes various pedantic points about etymology which I’ll spare the reader, except for this one: “the term ‘logos’ derives its meaning from the horticultural activity of ‘collecting’ and ‘dispersing’ seeds” (p. 252).
It’s natural to interpret Being & Time as “lay[ing] out the pre-theoretical understanding of the everyday work-world in which the self produces goods and satisfies its instrumental needs” (p. 253). Similarly, “work is the self’s way of ‘skillful coping’ in its everyday dealings with the world” (p. 254). Hence Heidegger emphasizes production — which he will later associate with technē — over exchange, which he associates with the ‘they-self’ (p. 254). Yet, Schalow points out, both production and exchange can be construed as a form of ‘care’. Care, in turn, is configured by temporality, which forces us to prioritize some things over others (p. 256).
“The paradox of time…is the fact that it is its transitoriness which imparts the pregnancy of meaning on what we do” (p. 257). Therefore, “time constitutes the ‘economy of all economies’,” in that “temporality supplies the limit of all limits in which any provision or strategy of allocation can occur” (ibid.). We can go on to say that “time economizes all the economies, in defining the horizon of finitude as the key for any plan of allocation” (p. 258).
In his later thought, Heidegger took on a more historical view, arguing that the structure of Being was experienced differently in different epochs. In our own time, the strongest influence on our notion of Being is technology. Schalow gives an interesting summary (p. 261):
The advance of technology…occurs only through a proportional ‘decline’ in which the manifestness of being becomes secondary to the beings that ‘presence’ in terms of their instrumental uses.
In an age where the economy is so large as to be inconceivable except through mathematical models, one can say that “the modern age of technology dawns with the reduction of philosophical questions to economic ones” (p. 260). Thus, Heidegger is more inclined to view economics as instrumental (technē) rather than as “the self-originative form of disclosure found in art (poiēsis).” Yet, rather than merely a quantitative “artifice of instrumentality,” it is also possible to interpret economics in terms of poiēsis, as “a vehicle by which human beings disclose their immersion in the material contingencies of existence” (p. 262). Economics thus becomes “a dynamic event by which human culture adjusts to ‘manage’ its natural limitations” (ibid.). Framing economics in terms of temporality (as ‘chrono-economics’) allows it to remain open to Being, and thereby “to connect philosophy with economics without effacing the boundary between them” (p. 263).
As late as 1898, logic was seen by the Chinese as “an entirely alien area of intellectual inquiry”: the sole Chinese-language textbook on logic was labeled by Liang Qichao (梁启超)—at that time a foremost authority on Western knowledge—as “impossible to classify” (无可归类), alongside museum guides and cookbooks (Kurtz, 2011: 4-5). This same textbook had previously been categorized by Huang Qingcheng (黄庆澄) as a book on ‘dialects’ (方言). The Chinese word for logic (luójí 逻辑) itself is, according to the Cihai (《辞海》/ Sea of Words) dictionary, merely a transliteration from the English—the entire Chinese lexicon had no word resembling it (Lu, 2009: 98). Hence it never occurred even to specialists that this esoteric discipline might have close affinities with the roots of Chinese philosophy, from the I Ching (易经) to the ancient Chinese dialecticians (辩者), as well as the famous paradoxes of Buddhism.
With the advent of computers, “there is now more research effort in logics for computer science than there ever was in traditional logics” (Marek & Nerode, 1994: 281). This has led to a proliferation of logical methods, including modal logic, temporal logic, epistemic logic, and fuzzy logic. Further, such new logical systems permit multiple truth values, semantic patterns based on games, and even logical contradictions. In light of these possibilities, research in ‘Chinese logic’ aims to reinterpret the history of Chinese thought by means of such tools.
This essay consists of three parts: the mathematics of the I Ching, the debates within the School of Names, and the paradoxes of Buddhism. The first section will, through examining the binary arithmetic of the I Ching, provide an introduction to basic logical notation. The second section will explore Gongsun Long’s famous bái mǎ fēi mǎ (白马非马) paradox, as well as the logical system of the Mohist school. The third section will explain the seven-valued logic of the Buddhist monk Nāgārjuna by way of paraconsistent logic.
1. The I Ching (易经) & Binary Arithmetic
The I Ching is one of the oldest books in history. Throughout the world, there is no other text quite like it. Its original function was for divination, giving advice for future actions; yet, after centuries of commentary, it has taken on a fundamental role in Chinese culture. In part, this is because its commentaries became (apocryphally) associated with Confucius, thereby establishing it as a classic.
Its survival of the ‘burning of books and burying of scholars’ (焚书坑儒) in 213-210BC has magnified the I Ching’s importance. Historically, the Zhou dynasty was marked by hundreds of years of war and dissension. Finally, Qin Shi Huang united the nation in 221BC, to become China’s first emperor. According to the standard account, in order to unify thought and political opinion, Emperor Qin Shi Huang ordered that all books not about medicine, farming, or divination be burned. And so, the vast majority of ancient Chinese knowledge has been lost to history. Yet, since the I Ching was about divination, it avoided sharing the same fate. In a sense, then, the I Ching has come to represent the collective wisdom of ancient China—it embodies their entire philosophical cosmology.
Confucius’s interest in the I Ching is well known. In verse 7.16 of the Analects, he says: “If some years were added to my life, I would give fifty to the study of the Yi [I Ching], and then I might come to be without great faults.” Curiously, this appears at odds with the rest of his philosophy. After all, the Analects elsewhere says: “The subjects on which the Master did not talk, were—extraordinary things, feats of strength, disorder, and spiritual beings.” (7.20). That is, Confucius had no interest in oracles. Hence we can conclude that for Confucius, the main content of the I Ching was not divination, but philosophy.
The core tenet of the I Ching is deeply metaphysical, namely: the complementarity of Yin (阴) and Yang (阳). Yin represents negativity, femininity, winter, coldness and wetness. Yang represents positivity, masculinity, dryness, and warmth. Accordingly, the gua (卦) or fundamental components of the I Ching’s hexagrams, are two lines: ‘⚋’ for Yin, ‘⚊’ for Yang.
The trigrams, made up of three lines, have 8 combinations (2³ = 8), and so are called the bagua (八卦), where bā (八) means 8. The bagua and its associated meanings are: ☰ (乾/天: the Creative/Sky), ☱ (兑/泽: the Joyous/Marsh), ☲ (离/火: the Clinging/Fire), ☳ (震/雷: the Arousing/Thunder), ☴ (巽/风: the Gentle/Wind), ☵ (坎/水: the Abysmal/Water), ☶ (艮/山: Keeping Still/Mountain), ☷ (坤/地: the Receptive/Earth). The I Ching’s commentaries revolve around 64 hexagrams of six lines (2⁶ = 64 combinations). There are multiple ways of ordering the hexagrams: the most well-known is the King Wen (文王) sequence, but the most important for our purposes is the Fu Xi (伏羲) sequence.
In the 17th century, the mathematician Gottfried Wilhelm Leibniz attempted to develop a system of arithmetic using only the numbers 0 and 1, called binary arithmetic. Binary arithmetic is in base 2: its key point is that any integer can be uniquely represented as a sum of powers of two. For example, 7 = 4 + 2 + 1 = 1×(2²) + 1×(2¹) + 1×(2⁰), and since each of the coefficients is 1, therefore the binary representation of 7 is (111). Conversely, 5 = 4 + 1 = 1×(2²) + 0×(2¹) + 1×(2⁰), where the middle coefficient is 0, so that 5 in binary is (101). For larger numbers, we simply include larger powers of two: 2³ = 8, 2⁴ = 16, etc.
Leibniz corresponded with various Christian missionaries in China, and had received a poster containing the Fu Xi sequence. To his astonishment, by letting ⚋ = 0 and ⚊ = 1, the Fu Xi sequence of 64 hexagrams exactly corresponds with the binary numbers from 0 to 63! Using the trigrams as a simplified example, from top to bottom we read: ☱ = (110) = 1×(2²) + 1×(2¹) + 0×(2⁰) = 4 + 2 = 6, ☵ = (010) = 0×(2²) + 1×(2¹) + 0×(2⁰) = 2, and so on. Thus, according to the Fu Xi and binary sequence, the bagua are ordered as: ☷, ☶, ☵, ☴, ☳, ☲, ☱, ☰.
Further, since we can treat the trigrams as numbers, we can also perform on them arithmetic operations such as addition and multiplication. To do this involves modular arithmetic, which for pedagogical purposes is occasionally called ‘clock arithmetic’. Its main feature is that it is cyclical: after arriving at the base number (‘mod n’, in our case: mod 2), we start up once again at zero. So in mod 2 arithmetic, 1 + 1 = 0: we only use the numbers 0 and 1. In the same way, a 12-hour clock only involves the numbers 1 to 12, and so is ‘mod 12’; hence, 15:00 is the same as 3:00, and so on. Therefore, the mod 2 addition of the I Ching’s trigrams can be represented by the following table:
Note that this is equivalent to the ‘⊻’ (exclusive or) operation in Boolean logic. (Boolean logic simply uses 0 for ‘false’ and 1 for ‘true’.) This logical point of view comes most in handy for defining multiplication, since binary multiplication is equivalent to the logical ‘∧’ (and) operation (Schöter, 1998: 6):
The advantage of logic over modular arithmetic is that we can define complements (¬). For example, Fire (☲/101) and Water (☵/010) are complementary, and so are Sky (☰/111) and Earth (☷/000). The use of logic is actually quite helpful in analyzing the trigrams’ associated meanings. Using the slightly different terminology of lattice theory (Schöter, 1998: 9):
- The Creative [乾/☰] is the union (⊻) of complements.
- The Joyous [兑/☱] is the union (⊻) of the Arousing [震/☳] and Abyss [坎/☵].
- Fire [火/☲] is the union (⊻) of the Arousing [震/☳] and Stillness [艮/☶].
- The Gentle [巽/☴] is the union (⊻) of the Abyss [坎/☵] and Stillness [艮/☶].
- Arousing [震/☳] is the intersection (∧) of the Joyous [兑/☱] and Fire [火/☲].
- Abyss [坎/☵] is the intersection (∧) of the Joyous [兑/☱] and Gentle [巽/☴].
- Stillness [艮/☶] is the intersection (∧) of Fire [火/☲] and the Gentle [巽/☴].
- The Receptive [坤/☷] is the intersection (∧) of complements.
In a beautiful essay, Goldenberg (1975) uses a branch of mathematics called group theory to unify the above points. A group is an algebraic structure with two operations (e.g. addition and multiplication). It turns out that the I Ching’s hexagrams satisfy many of the conditions for a group, which are as follows. 1) Closure: any operation between two hexagrams produces a new hexagram. 2) Associativity: in arithmetic operations, the order of the hexagrams does not matter, e.g. (☵ + ☴) + ☳ = ☵ + (☴ + ☳) = ☲. 3) Identity Element: there exists a hexagram (the identity element) such that an operation with it and any other hexagram produces that same hexagram, e.g. ☷ + ☱ = ☱, as well as ☰ × ☱ = ☱. 4) Inverse: for every hexagram, there exists another hexagram, such that an operation combining them produces the identity element; here, for the addition operation, every hexagram is its own inverse, e.g. ☶ + ☶ = ☷. Note, however, that there does not exist a multiplicative inverse. Further, addition and multiplication both satisfy the property that a ⋅ b = b ⋅ a, so that the hexagrams are commutative. So while the hexagrams’ lack of a multiplicative inverse precludes them from being a group, since they satisfy the remaining properties they are thus a ‘commutative ring’.
