This chapter criticizes two disagreement arguments for pessimism. The first, due to David Chalmers, asserts on empirical grounds that there is no large collective convergence to, or agreement on, the truth on the big questions of philosophy. The second, inspired by Peter van Inwagen, asserts that disagreement in philosophy is of a certain special epistemological kind, viz., it rationally requires suspension of judgement, at least in many cases; hence progress is impossible. The existence of ‘epistemic peers’ as a condition of suspension of judgement is discussed. It is suggested that neither argument is persuasive. The chapter ends by asking whether any argument from disagreement may succeed.
