It is not well known that Moritz Schlick, whose name is inseparable from the development of logical positivism, was extremely critical of positivism prior to the 1920's. Understanding Schlick's early criticisms of positivism not only puts Schlick's transition from his early realist to his later positivist views in better perspective, but clearly shows the role of relativity theory in turning Schlick's attention to a positivist concern with empirical verification. It also can be seen that Schlick spent the second part of his philosophical career struggling to find solutions to the very problems he had criticized so vehemently in his early work.

This essay is an attempt to gain better insight into Russell's positive account of inductive inference. I contend that Russell's postulates play only a supporting role in his overall account. At the center of Russell's positive view is a probabilistic, Bayesian model of inductive inference. Indeed, Russell and Maxwell actually held very similar Bayesian views. But the Bayesian component of Russell's view in Human Knowledge is sparse and easily overlooked. Maxwell was not aware of it when he developed his own view, and I believe he was never fully aware of the extent to which Russell's account anticipates his own. The primary focus of this paper will be the explication of the Bayesian component of the Russell-Maxwell view, and the way in which it undermines judgment empiricism.

In a recent article, Grover Maxwell presents a case for a kind of mind-brain identity theory which he claims precludes materialism. His case is based on some views about meaning which I find plausible. However, I will argue that, by adopting certain assumptions about the nature of sensory experience, and extending some of Maxwell's views about meaning in a plausible way, the issue of a materialistic identity theory is reopened. Ultimately, I will agree that such a theory is not true, but more is needed to show this than Maxwell gives us. But the question of materialism is not thereby closed, because it has become axiomatic these days that materialism does not require an identity theory. So I will go on to consider if all forms of materialism have been ruled out by Maxwell's theory, as extended by me. I will end with a tentative affirmative answer but also with a proposal which, if it can be worked out, would reverse the decision.

In the 19th century, "Psychophysical Parallelism" was the most popular solution of the mind-body problem among physiologists, psychologists and philosophers. (This is not to be mixed up with Leibnizian and other cases of "Cartesian" parallelism.) The fate of this non-Cartesian view, as founded by Gustav Theodor Fechner, is reviewed. It is shown that Feigl's "identity theory" eventually goes back to Alois Riehl who promoted a hybrid version of psychophysical parallelism and Kantian mind-body theory which was taken up by Feigl's teacher Moritz Schlick.
