John MacFarlane is a professor in the Department of Philosophy and the Group in Logic and the Methodology of Science at the University of California, Berkeley. He is the author of Assessment Sensitivity: Relative Truth and Its Applications (2014) and Philosophical Logic: A Contemporary Introduction (2021).
This is an excellent book that makes an important and original contribution. Many observers outside of philosophy are puzzled by the fact that problems about vagueness have been such a preoccupation in the philosophy of language, but Word and Plan explains precisely why these issues are so important. MacFarlane’s arguments, both constructive and critical, are incisive and convincing. -- Robert Stalnaker, author of <i>Propositions: Ontology and Logic</i>
