Dualisms have had a hard time in recent years. Philosophers used to think that facts and values were distinct, and that philosophy and science were radically different enterprises. While scientists employed empirical methods to discover the way the world happens to be, the job of philosophers was to use conceptual analysis to reveal how the world necessarily is. In the wake of the revolution unleashed by Quine in the early 1950s, philosophers either had to learn some science, find another job, or fight an irredentist action on behalf of conceptual analysis that is mainly of interest only to a few other philosophers.
The loss of these comfortable dualisms has upset the complacency of scientists as well as philosophers. Ethics cannot be ignored when the NIH requires ethics modules as part of all new training grants, when human and animal research must be approved by university committees, and when both the general public and "opinion leaders" feel free to comment on a wide range of issues that a generation ago might have been regarded as purely scientific.
