中国思想比西方思想更着重情感因素。西方语言讲 “mind” 或相对应的词汇，东亚语言如韩文、中文、日文则说「心」；前者假设思维活动无需情感，后者则无此假设。在这方面，东亚的思想其实更切合我们的心理，因为心智的认知能力涉及信念，而信念本身又必涉及情感。如果心理的正常运作需要情感，那么许多西方的伦理观念便错了。康德和一些较近期的理性主义者认为，道德知识以及建基于道德知识的动机无需情感即可产生。假若如我所言这种观念是错误的，那么道德理性主义便不再是一个伦理学选项。有趣的是，中国思想从来没有支持过任何（纯粹的）理性主义伦理学；在儒家思想的道德德性中，理性最多也只是与情感一起发挥作用。而且，在众多中国思想家中，至少有一位是纯粹的道德情感论者，那就是孟子。孟子的「四端」，作为情感反应，构成了道德德性的基础。在西方，休谟以及其他一些思想家对道德的基础也有类似的见解。因此，假如理性主义可以抛弃，那么，真正的问题就是：纯粹情感主义，或者某些情感和理性因素的结合，可否视为道德思考和道德德性的正当基础？本讲将简论纯粹情感主义，并集中探讨孟子／休谟的观点。

The seminar will focus on ways the traditional Chinese ideas of yin and yang can be made relevant to contemporary philosophizing. I will give four different lectures illustrating this point and showing in particular how yin/yang can help us in epistemology, ethics, philosophy of mind, and metaphysics more generally. The students are not expected to do any reading in advance of or for the seminar, but their eventual papers, due in May, 2018, should represent some kind of following up on the ideas mentioned and discussed during the seminars. This could involve reading more Chinese classics, but also or independently could involve interaction with various aspects of present-day or recent Western philosophy. The students writing the papers are encouraged to engage critically with the content of the lectures and/or to further develop some of the themes of the lectures. Papers should be at least 5000 words in length.
时间：16:30 – 18:30
Recent Chinese philosophy has to a large extent looked to Western philosophy for guidance, direction, and renewal, but this has involved a neglect of certain Chinese categories that can do a lot of important work for philosophers East and West. However, in order to be thus relevant the categories need to be updated or winnowed. For example, yin and yang are traditionally associated with physical concepts like wet and dry, cold and warm, and Chinese philosophers have, I think, rightly seen that such thinking is not going to be much help to present-day philosophy. But deep within traditional Chinese thinking, there is also a tendency to view yin as something like receptivity and yang as something like directed activity or purpose, and thus understood, yin and yang and yin/yang can, unexpectedly, help us better understand ethics, epistemology, and philosophy of mind.
In ethics, for example, a virtue like compassion or ren has both a yin and yang aspect: involving as it does both empathic receptivity to the suffering of another and motivation directed at helping the other. As with yin and yang, I shall argue that these two sides of compassion and other moral emotions are mutually dependent or complementary. In philosophy of mind, belief and desire are often seen as the main basic elements of psychological functioning, and it can be argued that both these components of the mind or heart-mind involve emotion. Belief is receptive or yin emotion and desire is actively directed yang emotion, and given these two complementary forms of emotion, it is natural to think that there is something more general that can be called emotionality and that can assume these different and complementary emotional forms. And emotionality can be equated with qi as it appears within the heart-mind.
Dao is a much honored and central notion in Chinese thought, but it doesn’t as such mandate any specific qualities as virtues or any specific actions as morally incumbent on us. By contrast, I argue, yin/yang enables us to explain how and why compassion, etc., are virtues. It thus does more moral-theoretic work for us, but it is then possible to understand Dao in the light of the foundational emphasis on yin/yang. Dao may make no specific moral recommendations, but it does embody the idea that truly understanding the ultimate order of things necessitates a commitment to living in accordance with that order. This means that if we are really receptive to how things are we will act virtuously, and in the terms I defend, this also means that Dao can be understood as the basic idea that yin requires and calls for yang. There is also the idea that yang requires yin, and I believe this fundamental idea is embedded in the concept of Tiandi. The yang of Heavenly activity cannot occur without Earth’s being receptive to that activity, for in the absence of Earth, Heaven has nothing to work on. So in the light of what I have to say about yin/yang we can give Dao and Tiandi philosophically justifiable places within contemporary philosophical thinking.
If time permits, I will extend my yin/yang analysis to the natural world outside mind or xin. If it applies there, then qi and taiji can be thought of as basic to the whole cosmos: both humans and nature—just the way Zho Dunyi thought. But my argument will depend on facts of modern physics Zho was of course unaware of. Newton’s laws instantiate yin and yang, as do familiar laws in chemistry and biology. But then, if both nature and humans exemplify the same basic yin/yang, there is a harmony to the entire universe that Western philosophy has never dreamt of. Chinese thought has traditionally believed in such harmony or he, but it helps to use modern physics and certain Western-style arguments in order to show how and why this is the case. Chinese optimism about the universe and ourselves is to that extent vindicated against pessimistic Western dualism and epistemological skepticism.
