现实主义与乌托邦

不可知的现实 现实问题在于我们认为对它非常了解,而事实上对它完全没有很好地理解.[1]过去,我们的过去,对我们来说似乎绝对清晰,但事实并非如此.如果我们反思通盘考虑起来是我们的过去的20世纪,我们逐渐认识到,作为20世纪主要标志性现象的共产主义和纳粹主义几乎未被给予系统化的思考.     

RATIONALITY AND MORAL REALISM

What can a moral realist say about why we should take morality seriously and about the relation between morality and rationality? I take off from Christine Korsgaard's criticism of moral realism on this score. The aim is to achieve an understanding of the relation between moral and rational properties and of the role of practical deliberation on a realist view. I argue that the justification for being concerned with rational and moral normative properties may not be an aspect of our minds to which we have access. I argue against a view that gives automatic pride of place to the rational properties of our mind by drawing attention to valuable non‐rational modes of thought such as creative, imaginative and instinctive thought. Thus the value of taking account of rationality is contingent on its benefits. But this is not why we should be taking account of morality.     

SUPERVENIENCE AND MORAL REALISM

Simon Blackburn has developed an interesting challenge to moral realism based on its alleged inability to account for supervenience relations between the moral and nonmoral. If supervenience holds, then any base property once giving rise to a supervening one must always do so. The realist accepts supervenience, but also (according to Blackburn) accepts the claim that nonmoral base properties do not necessitate the moral ones that supervene on them. This combination is thought deadly, because it leaves the realist without an explanation of why ethical supervenience should be true. I offer three responses on behalf of the moral realist. The first rejects the need for explanation, arguing that supervenience should be understood as closely analogous to Leibniz's law, which, I argue, needs no defense. I next argue that ethical naturalism may be right, and if so, would provide an adequate response to Blackburn. Lastly, I show that the success of Blackburn's arguments implies a global antirealism, and so does not, as he claims, amount to a special problem for realism in ethics.     

LOCKE ON SENSITIVE KNOWLEDGE AND THE VEIL OF PERCEPTION – FOUR MISCONCEPTIONS1

Abstract: Interpreters of Locke's Essay are divided over whether to attribute to him a Representational Theory of Perception (RTP). Those who object to an RTP interpretation cite (among other things) Locke's Book IV account of sensitive knowledge, contending that the account is incompatible with RTP. The aim of this paper is to rebut this kind of objection – to defend an RTP reading of the relevant Book IV passages. Specifically, I address four influential assumptions (about sensitive knowledge) cited by opponents of an RTP interpretation and argue that in each case the assumption is false.     

SCIENTIFIC REALISM AND METAPHYSICS

The tendency to take scientific realism to be a richer metaphysical view than it ought to be stems from the fact that there are two ways in which we can conceive of reality. The first is to conceive of reality as comprising all facts and the other is to conceive of it as comprising all and only fundamental facts. I argue that scientific realism should be committed to the factualist view of reality and not, in the first instance, to the fundamentalist. An anti‐fundamentalist conception of reality acts as a constraint on scientific realism, but it is a further and (conceptually) separate issue whether or not a scientific realist should come to adopt a fundamentalist view of reality. I argue that scientific realism is independent of physicalism and non‐Humeanism and that the concept of truth is required for a sensible understanding of the metaphysical commitments of scientific realism.     

A TRUTHMAKING ACCOUNT OF REALISM AND ANTI‐REALISM

Realism and anti‐realism about a domain of thought are metaphysical theses that involve the natures of the truthmakers in that domain and the truthmaking relation that is operant in the domain. Truthmaker theory is not exclusive territory for realists: anti‐realist views are also best understood in terms of how they understand truthmakers and truthmaking. In particular, I explore the possibility of projectivist truthmaking, and show how it makes sense of quasi‐realism. In addition to critically examining some extant accounts of the relationship between realism and truthmaking, I offer an account that best captures the nature of the various realism debates.
