 Peirce’s contribution to the social epistemology of science is commonly taken to be his consensual theory of truth: “The opinion which is fated to be ultimately agreed to by all who investigate is what we mean by truth, and the object represented is the real.” (Peirce 1878, 133) While often read as meaning that the truth is whatever the community of inquirers converges on in the long run, the notion is interpretable as meaning more precisely either that truth (and “the real”) depends on the agreement of the community of inquirers or that it is an effect of the real that it will in the end produce agreement among inquirers. Whatever the correct reading of this particular statement, Peirce elsewhere makes it clear that, in his view, truth is both attainable and beyond the reach of any individual. “We individually cannot hope to attain the ultimate philosophy which we pursue; we can only seek it for the community of philosophers.” (Peirce 1868, 40). Peirce puts great stock in instigating doubt and critical interaction as means to knowledge. Thus, whether his theory of truth is consensualist or realist, his view of the practices by which we attain it grants a central place to dialogue and social interaction.
