Working on my Economics in Two Lessons book, I’ve had to address the concept of Pareto optimality, which naturally raises the question of how it fits into Pareto’s larger body of anti-democratic and anti-egalitarian thought, which culminated, at the end of his life, in his embrace of Mussolini’s fascism. This led me to an article (paywalled, sorry) published by Renato Cirillo, in 1983, defending Pareto against the charge of being a precursor of fascism. Cirillo asserts that, far from being a fascist, Pareto

“manifested consistently a strong attachment to a type of liberalism not dissimilar to the one later attributed to Mises and Hayek”

These are rather unfortunate examples, in view Mises writings in praise of fascism and work for the Dollfuss regime, and (even more), Hayek’s embrace of Pinochet, at the very time Cirillo was writing [^1].

This, along with my discovery that Locke was actively involved in the expropriation of the native American population, justified by his theory of property, led me (back) to the question of the relationship between the writings of political theorists (broadly defined to include economists, sociologists and philosophers engaged with these issues) and their personal political activity and commitments. I’ve come to two conclusions about this.

First, for serious writers on political theory, political engagement is and ought to be the rule rather than the exception. I don’t mean that philosophers should (necessarily) run for office. Rather someone whose political theory doesn’t lead them to have and express views on the great political issues of their day probably doesn’t much of interest to say about theory either (unless of course, their theory leads them to some form of quietism). That’s true of the writers whose commitments were creditable (for example, John Stuart Mill and Bertrand Russell) as well as the discreditable cases I’ve mentioned.

Second, it makes no sense to look at the theoretical writings and ignore the political commitments with which they are associated. For example, it is easy to construct readings of Pareto, Mises and Hayek in ways that make them appear either as friends or as enemies of political liberalism. Their (remarkably similar) actions make it clear which reading is correct. Eventually, of course, ideas outgrow their creators to the point where original intentions, and the texts in which they were expressed, cease to be relevant. But, as the Locke example shows, that’s a very slow process. As long as a writer is regarded as having any personal authority, the weight of that auhtority must be assessed in the light of their actions as well as their words.

[^1]: To be sure, none of these writers can properly be described as fascists – they aren’t interested in nationalism or in the display of power for its own sake. Rather, their brand of liberalism is hostile to democracy and indifferent to political liberty, making them natural allies of any fascist regime which adheres to free market orthodoxy in economics.
