This thesis investigates the metaphysical nature of necessity. My study focuses primarily on the reduction of metaphysical necessity and the question of whether a necessary truth can be reductively defined. Theodore Sider develops a new reductive account of metaphysical necessity. Unfortunately, the multiple realizability problem posed by Jonathan Schaffer undermines the credibility of Sider’s account. This underlies my motivation to search for a revised Siderian account of necessity. On this basis, I propose a modified version of Sider’s account and argue (...) that analytic, natural-kind and micro-reduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Since logical truths are necessary truths, analytic, natural-kind and micro-reduction truths are necessary truths as well. In this thesis, I will proceed as follows. Chapter 1 introduces Sider’s account of necessity. In particular, I focus on his analysis of the necessity of a micro-reduction truth. His analysis is largely constitutive of the notion of a metaphysical semantics and some associated notions. I reconstruct his analysis and articulate his metaphysical semantics and the associated notions. Chapter 2 presents and clarifies the multiple realizability problem of Schaffer. His critique shows that Sider’s metaphysical semantics cannot handle multiple realizability. Sider refutes this claim by arguing that the multiple realizability problem is a problem for his analysis of the necessity of a micro-reduction truth, not for his metaphysical semantics itself. This is a good starting point to propound a modified account of necessity. Chapter 3 proposes and articulates my modified analysis of the necessity of a micro-reduction, where I show that the necessity of a micro-reduction truth can be reductively defined without appeal to Sider’s metaphysical semantics. I argue that analytic, natural-kind and microreduction truths are necessary truths if and only if they express the same states of affairs as logical truths. Logical truths are necessary and so are they. After that, I consider a potential objection to my modified account and attempt to respond to it. (shrink)

Reconstructing the content of Xunzi’s moral knowledge is the main goal of this thesis. A first main task of this reconstruction is to provide a clarification of the content and functions of li. A second primary goal of the reconstruction is to discuss the roles and functions of the moral sage or morally superior person, junzi, in Xunzi’s account of moral practice. The figure of the sage is important in explaining the rationale of li and exemplifying how to behave in (...) accordance with the rules of proper conduct in different situations. As truth is essential to knowledge, it is crucial to understand how moral belief can be truth-apt within Xunzian theory. To that end, the thesis reinterprets the doctrine in terms of Railton’s subjective naturalism. In the literature on Xunzi’s moral thought, the problem of the cognitive status of moral judgment has been neglected, and this thesis attempts to remedy this oversight. This thesis is divided into two parts. Part one mainly elucidates the content of Xunzi’s moral knowledge. It includes an exposition of the origin and several functions of li and the significance of the sage and his or her close relation with li. In part two, the argument focuses on whether Xunzi’s moral knowledge is truth-apt and reconstructs his position into terms of subjective naturalism. (shrink)

Section 1 of this thesis investigates one issue in meta-ethics, namely, the nature of moral judgments. What are moral judgments? What does it mean by "wrong" when we assert "Killing is wrong?" Neo-sentimentalism is a meta-ethical theory which holds that the judgment that killing wrong is the judgment that it is appropriate to have a particular negative emotion towards the action. In other words, to judge that murder is wrong is to judge that we have a right reason for having (...) a negative emotion towards the behavior. In the framework of neo-sentimentalism, the concepts of wrongness consist of negative emotions. If the moral judgment is the judgment that it is appropriate to have a negative emotion towards the action, and the concept of wrongness contains a negative emotion, then the following question is what emotions are. In section 2, I endorse the bodily attitudinal theory of emotions, a view which holds that a conscious physiological reaction which induces behavior disposition and the change of facial expression and internal organs is necessary for having an emotion. This section also articulates and replies to three major objections towards the bodily attitudinal theory of emotion. (shrink)
