This chapter is adapted from Siegel, in which I argue that the critical thinker is best thought of as one who is appropriately moved by reasons. In this view, critical thinking involves a variety of reasoning and other cognitive skills; knowledge of various sorts; a set of tendencies or dispositions to exercise those skills and utilize that knowledge; the valuing of reasons and an appreciation of their epistemological force; and a certain sort of character. I am grateful to David Moshman (...) and Carol Crowley for helpful comments on an earlier draft. (shrink)
