Shifting the Metaphor: Examining Discursive Influences on the Supreme Court's Use of the Marketplace Metaphor in Twenty-First-Century Free Expression Cases

Abstract

Justices on the Supreme Court of the United States have employed the marketplace-of-ideas metaphor to communicate how they understand freedom of expression for nearly a century. The meanings behind metaphors, however, are not static. This article examines whether justices’ references to the metaphor in twenty-first-century cases remain primarily tied to the original meaning – one related to the Enlightenment ideas at the heart of Justice Oliver Wendell Holmes's first use of the metaphor in 1919 – or if the meaning has shifted to represent more discourse-based understandings of communication in democratic society, such as those put forth by John Dewey and Jürgen Habermas. This article, through an analysis of twenty-first century Supreme Court decisions that discussed the marketplace metaphor, identifies evidence of a shift in the Court's understanding of the foundational theoretical concepts behind the meaning of the metaphor.
