Abstract

There is a certain tangle of philosophical questions around which much philosophy, especially in our time, has circled, to the point where now there is something that deserves to be called a holding pattern around these issues: What are causes? How do they compare with reasons? What is Reason, with a capital R? How does it participate in the production of intentions that lead to action, particularly in arenas rife with uncertainty? Where do formal systems of symbols come into all of this? And how - if at all - can formal methods be harnessed to serve science and public policy, through guiding belief formation and decision-making? Henry Kyburg, Jr., has himself circled around this tangle of questions, at least once or twice. And so in his honor, and in the no-nonsense spirit of empiricism that marks his work as the work of a scientist, I'd like to sketch a way to cut through some of the Gordian knots at the center of this tangle. The theme will be that natural science has much of value to offer that has been willfully neglected by philosophers. This by itself is nowise surprising, as philosophy, particularly in the most exclusive parts of the academy, has suffered from an excessive transcendentalism - a theme to which I will return in this piece periodically. Now Kyburg has not been guilty of contributing to the causes for the decline of philosophy. He has, instead, been courageously working out the implications of his convictions regarding the virtues of vigorous formal systems, contributing to the advancement of empiricist methodologies, and generously supporting the causes of realism. In emulation of that courage, I offer this essay in the service of bold and vigorous formal systems, realism and - most emphatically - empiricism.
