Explaining Normativity: On Rationality and the Justification of Reason

Aspects of the world are normative in as much as they or their existence constitute reasons for persons, i.e. grounds which make certain beliefs, moods, emotions, intentions or actions appropriate or inappropriate. Our capacities to perceive and understand how things are, and what response is appropriate to them, and our ability to respond appropriately, make us into persons, i.e. creatures with the ability to direct their own life in accordance with their appreciation of themselves and their environment, and of the reasons with which, given how they are, the world presents them.
An explanation of normativity would explain the various puzzling aspects of this complex phenomenon. In particular it would explain how it is that aspects of the world can constitute reasons for cognitive, emotive, and volitional responses; how it is that we can come to realise that certain cognitive, emotional or volitional responses are appropriate in various circumstances, and inappropriate in others; and how it is that we can respond appropriately. This paper explores an aspect of the last of these questions.     

Justification of Induction: Russell and Jin Yuelin. A Comparative Study

Jin Yuelin (1895–1984), a Chinese logician and philosopher, is greatly influenced by Hume's and Russell's philosophies. How should we respond to Hume's problem of induction? This is an important clue to understand Jin's whole philosophical career. The first section of this paper gives a brief historical review of Russell and Jin. The second section outlines Hume's skeptical arguments against causality and induction. The third section expounds Russell's justification of induction by discussing his views on Hume's skepticism, causality, principle of induction, and empirical postulates. The fourth section clarifies Jin's justification of induction by discussing his critique of Hume's epistemology and his arguments for the reliability of causality and the eternal truth and apriority of the principle of induction. The final section compares Jin's justification of induction with Russell's and concludes that there are similarities and differences between their projects and that both their attempts fail. This paper takes the similar responses to the problem of induction by Jin and Russell to demonstrate the communication that there has been between Chinese philosophers and the Western ones.
