Philosophy is, moreover, essential in assessing the various standards of evidence used by other disciplines. Since all fields of knowledge employ reasoning and must set standards of evidence, logic and epistemology have a general bearing on all these fields. Still another value of philosophy in education is its contribution to one's capacity to frame hypotheses, do research, and put problems into manageable form. Philospohical thinking strongly emphasizes clear formulation of ideas and problems, selection of relevant data, and objective methods for assessing ideas and proposals. It also emphasizes development of a sense of the new directions suggested by the hypotheses and questions one encounters in doing research.
Philosophers regularly build on both the success and failures of their predecessors.
A person with philosophical training can readily learn to do the same in any field.
