The question of what is philosophy, leads, it would seem, inevitably to diverse and conflicting, if not at times contradictory, answers. It is not only a matter of different philosophic perspectives, but also of fundamentally opposed conceptions of philosophy. Varying philosophic intentions and aims underlie what is taken to be the nature of philosophy and disagreement abounds. Philosophies then tend to differ not so much in terms of what they disagree about but what they consider philosophically sound and important. Phenomenology may share some concerns about basic philosophic problems, like intentionality, with ordinary language philosophy. But they diverge again sharply about the question of what philosophy should accomplish for, and what difference it makes to, human knowledge and understanding. The one sees intentionality as the pervasive structure of human consciousness and reality, and the other sees it as simply part of the various ways in which the uses of language can explain, and thus do away with, philosophical questions on perplexity. This difference about what philosophy should accomplish, its purpose, is not resolvable. It is what on each approach must be considered the very nature of philosophy and its primary task.
