Abstract

George Berkeley's first published work, An Essay towards a New Theory of Vision was prepared simultaneously with his second, A Treatise Concerning the Principles of Human Knowledge. In the New Theory, Berkeley argues that visual objects are in the mind, mind‐dependent ideas, but he appears to leave tactile objects outside the mind in mind‐independent space. The position the New Theory refutes is not the one that Berkeley identifies as causing problems for the Principles. But he still sees the New Theory as contributing an important step in the argument of the Principles. He is frequently said to have employed a language analogy, to have compared vision to language, and indeed he does just that through the New Theory. Berkeley apparently assumed that anyone who read both the New Theory and the Principles would be in a position to appreciate the usefulness of the New Theory for the moral and theological aims of the Principles.
