In the writings of both C. S. Peirce and Sir Karl Popper, we can find “objectivity” defined in the pragmatic sense as being in essence “intersubjective agreement.” The present paper is focused on the general relationship between the conception of objectivity in the above pragmatic sense, and the conception of objectivity in the classical realistic sense of “nonsubjectivity,” or brute otherness, as expressed by Peirce in its purest form in his category of secondness.

"This monograph is written with admirable lucidity and delightful wit. In using humor as a weapon in philosophical argument it is beautifully in the Russellian tradition. The arguments appear to be devastating. Defenders of Heidegger will have a hard time trying to answer it." --J.C.C. Smart, Professor of Philosophy, The Australian National University.
