Abstract

The suggestions outlined here include the following. Money is a bundle of institutionally sustained causal powers. Money is an institutional universal instantiated in generic currencies and particular money tokens. John Searle’s account of institutional facts is not helpful for understanding the nature of money as an institution (while it may help to illuminate aspects of the nature of currencies and money particulars). The money universal is not a social convention in David Lewis’s sense (while currencies and money particulars are characterized by high degrees of conventionality). The existence of the money universal is dependent on a larger institutional structure and cannot be understood in terms of collective belief or acceptance or agreement separately focusing on money. These claims have important implications for realism about money.

What is money? What does money consist of? Does money have an essence? What

larger worldviews are revealed by different conceptions of money? How does money

originate, and how does it persist? Is money an institution or a convention? What is

the precise relationship between the material and the social in money? How do

particular items of money relate to money as an institution? Why are certain things

that are easily mistaken for money, not money? How does money exist? Is money

real, and if so, in what sense? Does money exist just in virtue of people believing that

it does, or is more involved? These are questions about the ontology of money.

Naturally, asking and answering these questions is a multi-disciplinary chal-

lenge. Contributions come, or should come, not just from economics, but from

sociology and anthropology, history and archaeology, political science and psy-

chology, and now also neuroscience. Such disciplines are built upon various

ontological presuppositions, but their practitioners seldom make them explicit and

systematically examine them (about economics, see Mäki 2001). In their accounts of

money, however, economists have been forced to address ontological issues

directly: money seems to be a sufficiently mysterious entity to trigger this mode of

scrutiny. Yet systematic ontological forays into the deep secrets of money have not

been encouraged by the disciplinary conventions of economics, and no unified

consensus conceptions have emerged. The reflections to follow in the present essay

seek to go further by inserting additional philosophical detail to the endeavour

of disclosing money’s secrets. These selective notes seek to provide some novel

illumination on some of the questions above without, however, aspiring to offer

anything close to a full systematic account of the ontology of money.

Another body of literature that has discussed money as a paradigmatic

component of institutional reality is social ontology done by philosophers. The

reflections of the present paper seek to contribute to this literature. By pointing out

some gaps and shortcomings in the philosophers’ discussion, I propose some

directions in which social ontology should be further elaborated in its dealings

with money. Given that money is part of institutional reality – and a very signifi-

cant part for that matter – the observations to be made may also highlight some

aspects in the ontology of the institutional world more generally (but such im-

plications will not be pursued here).1

1 Unfortunately, philosophical social ontology has done too little to promote interactions and

collaborations with substantive disciplines such as economics, sociology, anthropology, political

science, psychology, and others. This also applies to the reverse relationship: these other disci-

plines have not properly set out to learn from philosophical social ontology. In an ideal world,

there would be interactive mutual learning.

246 U. Mäki The claims and suggestions to be made and defended in this essay include the

following. Money is a bundle of causal powers sustained by an institutional

structure. Money is an institutional universal instantiated in specific currencies and

particular money tokens. Taken separately, John Searle’s (1995, 2005) account of

institutional facts is not very helpful for understanding the nature of money as an

institution (while it may help to illuminate some aspects of the nature of currencies

and money particulars). The money universal is not a social convention in David

Lewis’s (1969) sense (while currencies and money particulars are indeed charac-

terized by high degrees of conventionality). The existence of the money universal is

dependent on a larger institutional structure and cannot be understood in terms of

collective belief or acceptance or agreement separately focusing on money.

2 Money as a Bundle of Causal Properties

What is X? One way of making the question more specific is to ask, What is the

identity or nature or essence of X? Indeed, in examining the nature of money,

economists have been inclined to adopt unashamedly essentialist ways of talking:

they take questions of this form to be legitimate questions about money. Expressions

such as “essence”, “identity”, and “nature” are regularly used in accounts of money.

Essentialism of this sort seems to be a rather widely shared philosophy in action of

monetary theorists. It may be that it is in this part of economics that economists

subscribe to an apparently essentialist outlook more explicitly than elsewhere.

In line with a long intellectual tradition, economists make claims about the

essence of money by listing its “essential” or “intrinsic” properties. These prop-

erties are the essential “functions” of money. They include the functions of money

as a medium of exchange, as a means of payment, as a store of value, and as a

standard of value or unit of account. To this we may add a few more observations.

First, these functions are identity-constituting properties in that they determine

what it is to be money, thereby distinguishing money from other things such as

consumer goods and physical objects. This list of properties makes money what it is:

money.Theyconstitute the realessenceofmoney (thiswillbequalifiedin amoment).2

Second, natural necessity is involved here: money and its identity-constituting

properties are related to one another by real-world necessity (necessity de re).

Nothing can be money without having those properties, and nothing having those

properties can fail to be money. This is natural necessity in the sense that is based

2 Note that I here suggest to locate the essence of money somewhat differently from the analysis of

Menger’s (1892) account of money offered in Mäki (1990). Yet the basic idea developed in the

present paper was introduced in that earlier paper.

Ontology of Money 247 on the nature of things, in this case the nature of money. De re necessity is a

modality that characterizes the relationship between essential properties and a

natural kind that obtains by virtue of the structure of the world (not by virtue of

how we decide to use words, which would give us de dicto necessity).3

Third, the list of properties is to be invoked in defining the concept of money.

Any such definition of the concept of money is therefore also a definition of money.

This means that such a definition is a real definition: a claim about the nature of

the thing defined, not just about a concept used to talk about it. Considered as

a definition of the concept of money, the list of properties determines its intension

(or intensional meaning). The intension of the term ‘money’ in turn determines its

extension (or extensional meaning), namely the class of objects to which the term

‘money’ correctly applies, that is the class of all items that are money, that have the

identity-constituting properties of money. Note that the “definitions of money”

that economists employ when distinguishing between what they denote as M1, M2,

etc. are definitions of the extensions or extensional meanings of the term “money”.

Fourth, economists and other social scientists hold rival views of the nature of

money. They have different conceptions about which of money’s functions are

indeed the essential or intrinsic functions, and how the functions relate to one

another, such as some of them being primary and others being derivative. This

means economists entertain different real definitions of money. The exchange

function is often thought to be the essential property of money, determining its

identity. “The essential function, the performance of which enables us to identify

money, is very simple: it is that of acting as a medium of exchange.” (Newlyn 1962, 1)

Others believe that it is the functions of money as a standard of value and as a

means of payment that are “intrinsic” to it, while the capacity of money to serve as

a store of value is “no distinguishing property of money as such” (Hicks 1989, 42).

Of the two distinguishing functions of money (as standard of value and means of

payment), these economists take the standard of value to be primary: it is pre-

supposed by the function of money as a medium of payment (ibid., 43). Even

though the reflections to follow in the sections below cite these functions as il-

lustrations, no stance will be taken as to how exactly they are supposed to be

related to one another.4

Fifth, I submit that what economists call the essential functions of money are

its causal properties. As suggested earlier (in Mäki 1990), they are a special species

3 Note that if any given account of the origin of money (such as money being an outcome of an

invisible-hand process, or of collective intentional action by a regulatory agency) is presented only

as a possible scenario, then such an account does not qualify as a description of an essential

property of money.

4 Most of the literature in social ontology dealing with money as part of institutional reality

restricts its attention narrowly to the function of money as a means of exchange.
