A survey of Descartes' scientific career from his student days at the Jesuit College of La Flèche to his departure for Sweden in 1649.

John King-Farlow's ‘The Positive McTaggart on Time’ brings out extremely important likenesses between ‘abstract’ metaphysicians and ‘concrete’ philosophers of science. These striking similarities illustrate a perennial human quest for Something More Basic than Time, a quest which characterizes not only mystics who rejoice in contradictions but hard-headed philosophers who submit to the rigours of logic. King-Farlow is largely concerned with the McTaggart of 1908 and his motivation for writing ‘The Unreality of Time’. I should like to explore further the surprising (...) bond between the Search for Something Deeper in the later McTaggart of The Nature of Existence and the writings on Time of Hans Reichenbach and Adolf Grünbaum. Reflection on this similarity should enable us better to evaluate the view that our vulgar, if practically useful, assertions about Time's Arrow must be reinterpreted by the wise in terms of chastened logical constructions out of statements about Something Deeper—logical constructions which are alleged, if chaste enough, to be eliminable.

The mainstream of the philosophy of science in the second quarter of this century—the so-called “logical empiricist” or “logical positivist” movement—assumed that theoretical language in science is parasitic upon observation language and can be eliminated from scientific discourse by disinterpretation and formalization, or by explicit definition in or reduction to observational language. But several fashionable views now place the onus on believers in an observation language to show how such a language is meaningful in the absence of a theory.In the (...) present paper, I propose to show why logical positivism failed to do justice to the basic empirical and logical problems of philosophy of science. I also wish to consider why the drastic reaction, typified by Thomas Kuhn and Paul Feyerabend, fails t o provide a suitable alternative, and to suggest that the radical approaches of recent writers such as Mary Hesse and Dudley Shapere hold out a genuine promise of dealing effectively with the central tasks that face the philosopher of science today.
