Given as an address to the American Philosophical Association on the occasion of its centennial, this paper examines the character and standing of American philosophy now and at the outset of the twentieth century as seen (then and now) from a British point of view. A century ago Britain was itself the unquestioned leader of Anglo-Saxon thought. Now, however, as in so many areas, the US is the pre-eminent world power. This status brings prestige and various benefits but it also carries responsibilities. In considering the latter I recall some virtues of an earlier generation of American philosophers, especially as they were possessed by William James.
