M. Davidson , "On Roderick M. Chisholm"
Roderick M. Chisholm (1916-1999) was one of the most important philosophical thinkers of the 20th century. His influence on epistemology (the theory of knowledge) and metaphysics cannot be understated; indeed, it is difficult to conceive of what these fields would be like today without the impact of Chisholm. Were there a Nobel Prize in philosophy, Chisholm surely would have won it.
Chisholm graduated from Brown University in 1938 and completed his Ph.D. at Harvard in 1942. After finishing his dissertation, "The Basic Propositions of the Theory of Knowledge", he entered the U.S. Army. After a short stint in infantry training, he received training in clinical psychology and did work at Army Hospitals in the southern United States.
After being discharged in 1946, Chisholm returned to Brown University where he taught until his death in 1999. During this time, he published hundreds of articles and many books, including Perceiving (Cornell University Press, 1957), three editions of Theory of Knowledge (Prentice Hall, 1966, 1977, 1988), Person and Object (George Allen and Unwin, 1976), The First Person (Minnesota University Press, 1981), and A Realistic Theory of Categories (Cambridge University Press, 1996).
Chisholm was perhaps known best for his attempts to bring clarity and rigor to philosophical thought. Philosophical analysis for Chisholm involved very precise, clear definitions of key concepts. In fact, the most widely-used term that comes from a philosopher's name is the verb "to chisholm."
The Philosophical Lexicon (http://www.blackwellpublishing.com/lexicon/) has the following entry:
[to] chisholm, v. To make repeated small alterations in a definition or example. "He started with definition (d.8) and kept chisholming away at it until he ended up with (d.8'''''''')."
One often will read sentences like "This idea needs some chisholming" or "This claim might make sense, but it would take much chisholming to see that it does." Another well-known term is a Chisholm-Style Definition. I've heard many times at conferences people ask for a Chisholm-style definition of some concept they found obscure. ・・
