The ‘marketplace of ideas’ is an influential metaphor with widespread currency in debates about freedom of speech. We explore a number of ways competition between ideas might be described as occurring in a marketplace and find that none support the use of the metaphor. We suggest that an alternative metaphor, that of the ‘garden of ideas’, may offer more productive insights into issues surrounding the regulation of speech.

ABSTRACT“Post-truth” politics is often framed as a failure of the competition of idea­s. Yet there are different ways of thinking about the competition of ideas, with different implications for the way we understand its benefits and risks. The dominant way of framing the competition of ideas is in terms of a marketplace, which, however, obscures the different ways ideas can compete. Several theorists can help us think through the competition of ideas. J. S. Mill, for example, avoided the metaphor of (...) the market by focusing, instead, on competition as the testing of arguments in adversarial encounters before a critical audience. Georg Simmel, alternatively, conceived of competition as a form of indirect conflict, where two individuals strive in parallel to gain audience approval. This view emphasizes innovation and creativity in the competition of “all for all.” More recently, theorists have developed the market logic of competition by thinking of a marketplace not for ideas but for rationalizations. This articulates some of the features of Simmel’s view of competition, but underestimates the degrees of constraint required to secure the goods of competition. Ultimately, recognizing these different modes of competition in the public sphere can enrich our theories of deliberative democracy and sharpen our view of the problem of “post-truth” politics.

I consider whether Mill intends for us to see the arguments that constitute his defense of the “Liberty of Thought and Discussion” in chapter 2 ofOn Libertyas a part of his larger case for the “harm” or “liberty” principle (LP). Several commentators depict this chapter as a digression that interrupts the flow between his introduction of this principle in the first chapter and his exposition and defense of it in the final three. I will argue instead for a reading ofOn (...) Libertyon which chapter 2 is well integrated with the rest of the essay and is in fact where Mill starts constructing his case for LP. (shrink)

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic rationality is (...) sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)
