What can Libertarians Learn from Foucault?

 

Before reading Mark Pennington’s recent book, Foucault and Liberal Political Economy: Power, Knowledge, and Freedom, it would not have occurred to me that libertarians could learn anything from the social theories of Michel Foucault. Pennington has persuaded me that some beliefs associated with Foucault, and postmodernism more generally, are not devoid of merit. As will be discussed below, however, the beliefs that he identifies as postmodern differ somewhat from the collection of beliefs that I have hitherto associated with postmodernism.

Pennington claims that liberals who are concerned about over-government can learn from Foucault about “multiple sources and potential forms of this ‘over-government’ in modern societies and how these threats to freedom have been neglected by, and in some cases resulted from, the dominant strands in liberal thought”.

The author aims “to enunciate the elements of a postmodern liberalism, and to show how this perspective might engage in a productive conversation with Foucault in ways that expose the illiberalism of contemporary societies and the dominant forms of social science and political philosophy that contribute to this state of affairs”.

Before considering Pennington’s claims about what liberals can learn from Foucault and the potential for liberals to engage productively with his ideas, I need to clarify how Pennington is able to argue that some of Foucault’s views are worthy of consideration and what Pennington means by “postmodern liberalism”.

Foucault’s views

 The main problem I have with the postmodernist movement is its disrespect for reason, truth and knowledge. Stephen Hicks suggests that Foucault’s views illustrate the direction and tone of the postmodern intellectual world:

“Michel Foucault has identified the major targets: “All my analyses are against the idea of universal necessities in human existence.” Such necessities must be swept aside as baggage from the past: “It is meaningless to speak in the name of—or against—Reason, Truth, or Knowledge”.” (The sources of the quoted passages are cited in Hicks, 2004.)

Hicks explains that Foucault reduces knowledge to an expression of social power and urges that we play the brutal power politics game on behalf of the traditionally disempowered.

Pennington recognizes that Foucault has often been accused of undercutting the basis of his own critical analysis:

“If all knowledge is reflective of an arbitrary ‘will to truth’, then what of Foucault’s own truth claims?” 

More specifically:

“If all truth claims are understood as merely a way of exercising power over others, then how are people to know which if any of the ‘intolerable’ practices they find themselves in are worth challenging or resisting, let alone what might replace them.”

However, Pennington observes that there are many Foucaults, “reflected in the shifting emphases, styles of analysis and reinterpretations of his own words”:    

“Towards the end of his life … notably in essays such as ‘What Is Enlightenment?’, Foucault softened the power/knowledge coupling, adopting a stance that does not deny that there are better and worse forms of argument or that there are some more or less valid forms of knowledge; rather, he emphasises the importance of uncertainty, of keeping all truth claims under scrutiny, and of being aware of the routinised social processes that might block that very scrutiny.”

If postmodernism is characterized by the idea that truth claims merely reflect the exercise of social power, perhaps it could be said that towards the end of his life, Foucault’s views became somewhat less postmodern.

 Postmodern liberalism

In outlining the elements of “postmodern liberalism” Pennington notes:

“This ‘postmodern’ liberalism has not previously been coherently articulated, but strands of it are detectable in the writings of F. A Hayek, those of Deirdre McCloskey, and elements of the contemporary Austrian school of economics, as well as in the context of political philosophy apart from Hayek in the works of Michael Oakeshott, Gerald Gaus, and Chandran Kukathas.”

I have considerable knowledge of the views of some of those authors and great respect for all of them. I am not comfortable with their views being labelled as postmodern, even though some of them might not object to that label.

Pennington seems to me to be distancing “postmodern liberalism” from postmodernism when he acknowledges that it is possible to assess “the comparative plausibility of competing narrative explanations” and “social scientific truth claims”.

In his concluding chapter Pennington notes that the elements of “postmodern liberalism” include, among other things, a “philosophy of social science sceptical of socio-economic positivism and the efforts of conscious control it fosters”.

It seems to me that Pennington’s philosophy of social science could appropriately be labelled “unpretentious liberalism”. It stands apart from the pretence of knowledge and scientism associated with socio-economic positivism, without endorsing postmodernism’s disrespect for reason, truth and knowledge.

I hope the book will attract many readers who identify as postmodernists and that they will be captivated by the concept of postmodern liberalism. However, those who (like me) are allergic to postmodernism, may find the book easier to read if they substitute the words “unpretentious liberalism” whenever they see “postmodernism liberalism”.

Should libertarians attempt to influence culture?

Before considering what libertarians can learn from Foucault, it seems appropriate to acknowledge that there is nothing new about the idea that libertarians should take an interest in culture.

That is apparent in the consideration of interactions between culture and political institutions in a discussion between Chris Matthew Sciabarra and me entitled, “Should Libertarians be Attempting to Influence Culture?” which published on this blog in September 2024. The discussion began by considering John Stuart Mill’s concerns about the “tyranny of the prevailing opinion and feeling” and moved from there to considering Sciabarra’s interpretation of Ayn Rand’s view of power relationships. Sciabarra presented a Tri-level Model of Power Relations which was first derived from his reconstruction of Ayn Rand’s critical analyses of social problems, outlined in Part Three of Ayn Rand: The Russian Radical (Sciabarra, 2013).

In introducing his discussion of Rand’s view of power relationships, Chris Sciabarra commented:

“Winton suggests that Enlightenment humanism has been preoccupied with reason and reality, while postmodernism has been preoccupied with the use of power. Hence, it is startling that Rand, who most certainly placed herself in the reason and reality camp, also emerged with a critique of power relations.”

The question under discussion provoked responses from several libertarians and classical liberals. The response of Douglass Rasmussen, joint author of Norms of Liberty (Rasmussen and Den Uyl, 2005) is pertinent to this essay:

“Is there not a difference between saying libertarianism qua political philosophy should attempt to change culture and saying that a libertarian concerned in advancing libertarianism should attempt to change culture? The former concerns what the political/legal order should do, and the latter concerns what individuals should do.”

As I see it, attempting to understand the consequences for liberty and individual flourishing of interactions between culture, markets, social movements and government regulation does not obviate or preclude attempts to define the nature of a political/legal order that can ensure that individuals can flourish in different ways without colliding.

Foucault’s liberalism

 From my perspective, one of the most interesting aspects of Foucault’s philosophy, as discussed by Pennington, is his account of discourses as a kind of spontaneous order phenomenon.  Foucault challenges the role of individual or collective agency in the operation of power regimes. Power works through chainlike or network effects. As people adopt certain discourses they influence the actions of others.

Power does not emanate from a single point in a network. It emerges from diverse and at time contradictory attempts by actors to assert their place in society. There is no identifiable author of power relations. As Pennington puts it:

“The discourses and disciplines producing people’s patterns of thought, positionality and interests are largely unintended consequences of the multiple attempts to affect the conduct of others.”

 Thus, while power relations may appear to have a coherent structure, there is no single purpose, intention, or meaning that underlies that structure.

States of domination arise when a set of discourses align or crystalize with each other and with the juridical power of the state. Scientific discourses can pose a problem where people come to be classified relative to various norms (e.g. as deviant, perverted, insane) and subjected to discipline (which may include social punishments). In addition, bio-power operates through interventions to change social, economic or environmental conditions in the name of improving population health or providing security.

Pennington suggests that “it is with Foucault’s concept of bio-power and especially its economic manifestations where the most significant possibilities for a dialogue between the Foucauldian and postmodern liberal perspectives lies”. Late in Foucault’s career he “seems to favour an environment that preserves a ‘pluralism of rationalities’ so that people might remain alert to the possibility of multiple ways of their being governed and not being frozen into a particular classificatory grid and the roles and positions it creates”.

In my view, Foucault’s decentred account of power relations is often more plausible than theories which reduce the exercise of power to holding of positions in political office. A decentred account is consistent with the conclusion of my recent series of essays on political entrepreneurship. Even though it is possible to identify the policies adopted in some countries with the ideologies of authoritarian political leaders, I suggest:

“The problem of ensuring adoption of government policies that more consistently advance economic and personal freedom cannot be reduced to the question of how to elect better political entrepreneurs to national leadership positions. Institutional change is a complex process involving social movements, media organizations, and interactions between individual citizens, as well as local and national politics.”

I concur with Pennington that Foucault’s view of power relations provides support for an unpretentious liberalism which is deeply skeptical of economic and philosophical approaches which presuppose that the welfare of the population can be secured by a form of expert rule.

In Part II of his book, Pennington uses his theoretical lens to examine complex networks of institutional, physical, and administrative mechanisms and knowledge structures associated with social justice, public health, ecological sustainability, and crime and punishment. He critically examines various overlapping systems of power - some focused on managing populations and others focused on guiding individuals. (In this paragraph I have relied on Claude, Anthropic's AI assistant, to help translate the technical Foucauldian phrasing in Pennington’s summary – words including “dispositifs”, “bio-political” and “pastoral” - into plainer English.)

These systems share three features: (1) an excessive faith that social and economic life can be understood and controlled with scientific precision, (2) a belief that some central “steering” intelligence can identify and fix deviations from expected patterns, and (3) a bureaucratic, top-down way of handling risk. The author demonstrates that these features tend to shrink the space in which individuals can act freely.

Conclusion

So, what can libertarians learn from Foucault? Pennington's answer, as I read it, is not that libertarians should adopt postmodernism's skepticism of reason and truth - that skepticism, taken to its logical end, undercuts the very possibility of arguing for freedom over domination. Rather, what is valuable in Foucault is his decentred account of power: the recognition that domination need not flow from a single source or a deliberate design, but can emerge from the unintended convergence of discourses, institutions, and expert classifications. This is a lesson that liberals have sometimes neglected, having focused their concern about over-government on the formal power of the state while overlooking the more diffuse mechanisms in social justice, public health, ecological policy, and criminal justice that narrow the space for individuals to govern their own lives.

What Pennington calls postmodern liberalism – I prefer to call it "unpretentious liberalism" - captures what is worth taking from this encounter: a liberalism skeptical of the pretence of expert knowledge and socio-economic positivism, without embracing postmodernism's disrespect for reason and truth. Pennington's Foucault, particularly the later Foucault of "What Is Enlightenment?", is compatible with this project because he does not deny that some truth claims are better than others - he simply insists that we remain alert to the ways power can masquerade as expertise, and that we preserve a plurality of ways of being governed rather than being frozen into a single classificatory grid. That, it seems to me, is a genuinely liberal insight, however unfamiliar its Foucauldian packaging may be to libertarians who have, like me, generally kept their distance from postmodern thought.
