Abstract
The question is raised whether there are forms of reasoning peculiar to philosophy. But if one considers what has been written over the centuries in the name of philosophy, it hardly seems possible that there is any form of ‘reasoning’, however widely one uses that word, which has not been employed. Formal deductive reasoning, appeals to empirical data, arguments from the way in which language is used, arguments from analogy—it is not difficult to think of examples of all of these and more. How effectively or successfully they have been used is, of course, another matter.
