Abstract

Contemporary social philosophy is paying increasing attention to the politics of language use, from social epistemology and questions of testimonial injustice to political worries about freedom of expression, silencing, and hate speech. We argue about how to reduce the harms arising from such injustices, but to solve these debates, we need a framework which lets us track how social change unfolds, and which lets us drive such changes toward more just outcomes. I argue that my Discourse Ecology Model serves this role, using a linguistically-informed model of language change to explicate the relationships between language users and their discursive, social, and political environments. With the Discourse Ecology Model in place, I follow the history of the rise and spread of veganism to see how linguistic habits and social habits interface with each other, and how we can cultivate changes in our environment that lead to widespread social change.
