Pragmatists have been eager to employ the method of science in philosophy, which meant, too, that they paid a great deal of attention to the attitudes that regulate the process of scientific or systematic inquiry. At the same time, they, at least in the nonstandard theories of emotion to be found in Charles Sanders Peirce and John Dewey, espoused a cognitivist view of emotion, which resonates with some of the concerns that have been at the forefront of the contemporary philosophy (...) of emotion. In particular, they converge upon the view that something like ‘emotional understanding’ is very important. While COPE, especially in the case of Julien Deonna’s and Fabrice Teroni’s ‘attitudinal theory of emotion’ which has some pragmatist affinities, is focused on showing how emotional understanding is central to moral agency, it is my aim in this paper to offer a pragmatist account of emotional understanding as ‘passionate reasoning’ that goes one step further. By highlighting the way in which emotions ought to be interpreted even in the context of scientific or systematic inquiries it makes a case for moralizing science from within, i.e. without submitting it to values that are alien to inquiry. In particular, passionate reasoning helps addressing three problems of inquiry: the problem of the lack of context, the problem of the problem wrongly put, and the problem of my problem. (shrink)
