According to the received view, the philosophy of C.I. Lewis is a form of phenomenalism. The first part of this paper is an argument designed to show that Lewis does not support one of the necessary conditions for ontological phenomenalism; namely, the sense-datum theory. The secondpart is an argument designed to show that Lewis’ theory is incompatible with linguistic phenomenalism, a view according to which there is an equivalence of meaning between physical object statements and sense-data statements. The argument is not merely that terminating judgments are not sense-data statements, but that they cannot be equivalent to objective statements.

This paper deals with the problem of the External World, taking its point of departure in Peter Zinkernagel's Conditions for Description. In the first section I try to give an outline of the theses contained in that book. In the second I raise a main objection against it, pointing out that Zinkernagel, in one respect, has not sufficiently sharpened the argumentation between phenomenalism and realism. In the third section I turn realism and phenomenalism sharply against each other, presenting the latter in a radical, yet consistent form; the section is an attempt to show how phenomenalism can be rejected.
