In lieu of an abstract, here is a brief excerpt of the content:The Religious Background of Seventeenth-Century Philosophy RICHARD H. POPKIN IT IS AN EXCEEDINGLY GREAT PLEASURE tO participate in the twenty-fifth anniversary issue of the Journal of the Historyof Philosophy.The editor, Professor Makkreel, offered me the opportunity to discuss the rationale for my present research, which I hope has some relevance for future research in the history of philosophy. At a symposium at the American Philosophical Association meeting in Washington (...) in December x985, I argued for taking the historyof philosophy seriously, that is, understanding thinkers and ideas in their actual historical contexts, instead of detaching them into some ahistorical ethereal realm. I argued that one could not make sense of a philosopher's thought detached from his time and circumstances. His ideas could not be understood unless one took account of the language, the usages, the issues and the concerns of the thinker and his time. The all too frequent "reconstruction" of philosophers ' thoughts sees them instead as logical machines, simply moving from clearly stated premises to their logical consequences. As many of us have sought to show, this often grossly distorts what Descartes, Spinoza, Locke, Leibniz and others might have actually thought, and misses much of what they were probably thinking about. I should like to carry this theme further by examining the need to take seriously the religious aspect of philosophizing. I will center on the intellectual scene of the seventeenth century, which I am currently working on though I believe many of the same points could be made about any period in the history of philosophy. Among historians of science there is an ongoing debate about whether the history of the subject should be studied internally or externally. The [:35] 36 JOURNAL OF THE HISTORY OF PHILOSOPHY internalists examine a set of ideas presented by scientist A, and trace their use or development by scientist B. The study that results is primarily the tracing of the course of a set of ideas through a time period. Background data about the scientists, their problems, and their place in society are regarded as of little relevance. The externalists insist that one cannot understand why various questions became important, why various individuals tried to solve them, why they used certain kinds of possible solutions instead of others, etc., unless one knows the external conditions of the time. This has spawned a lot of interesting research into the way scientific studies went on, who supported them, who did them, how they got accepted, and so on. The sociology and even anthropology of science is now a thriving research area, yielding many amazing studies about the scientific world and how it functioned. In so doing, scholars have not just examined the great successful scientists, the Keplers, Galileos, Harveys, and Newtons, but also the small fry, the mediocre, the poor scientists, and even the incompetent ones. They have examined why wrong-headed theories were supported, and accepted, while evidence supporting other theories was readily available. Their concern with the actual course of scientific development as an ongoing part of intellectual history is vital to understanding the scientific world of today, which plays such an overwhelming role in our society. So, some people study the education of the good, the mediocre, the bad scientists; their relative social statuses, incomes, and so on. The religious concerns are, of course, an obvious part of the story from Copernicus to Kepler to Newton to Darwin to Freud to Einstein. The scientists were involved in an ongoing religious world that influenced the role of science. The above named scientists had their religious or irreligious views that were involved with their scientific concerns. And, as we know too well, the impact of their work on religion has been of great importance to the broader intellectual world, and the impact of religion on the acceptance of their science has been and is part of the ongoing intellectual world. This interest amongst historians of science in the sociology, psychology, and anthropology of science has hardly rubbed off on the historians of philosophy. Most of the leading scholars of the last few decades in this work are hardly known and rarely cited in studies in the history of philosophy. We... (shrink)
