The series on “The Embedding Objection” continues. The first post explained what I take expressivism to be. The second post distinguished four main kinds of expressivism: Simple non-truth-evaluable expressivism (e.g., Ayer’s emotivism), Simple minimalist expressivism (e.g., Blackburn’s projectivism), Complex minimalist expressivism (e.g., Stevenson’s emotivism), and Complex robust expressivism (e.g., Hare’s prescriptivism, my Expressive-Assertivism). The third post discussed The Objection from Truth Ascriptions. In this post, I discuss what I used to believe was the most pressing difficulty for expressivists, what I call “The Challenge from Incomplete Semantics.”
