C. S. Peirce made the following claim: If science reveals truth, then consensus among scientists can be expected in the limit. This article does not dispute this claim; it simply assumes it. On the basis of this assumption, the following question is asked: Is it possible to extend Peirce's claim to philosophy in a natural way? It is argued that two important differences between science and philosophy strongly militate against such an extension. Does this mean that there is no truth to be found in philosophy? Are there, perhaps, different kinds of truth (scientific, philosophical, religious, and so on)? But such questions, though related to the present investigation, are nevertheless well beyond the scope of this article
