Causal decision theory

On the dominant view of vagueness, if it is vague whether Harry is bald, then it is unsettled, not merely epistemically, but metaphysically, whether Harry is bald. In other words, vagueness is a type of indeterminacy. On the standard alternative, vagueness is a type of ignorance: if it is vague whether Harry is bald, then, even though it is metaphysically settled whether Harry is bald, we cannot know whether Harry is bald. On my view, vagueness is neither a type of indeterminacy nor a type of ignorance. Rather, it is sui generis.     

《老子》形而上学研究

善是道德价值。它是私意的表达。因此,《老子》认为,善恶是非不分,需要破除。言即知识,是对事实的陈述。它有所限定,即局限性,彼此有别,因此也要放弃。有即万物。有具有主体性。有即现象,为假,不是事物的本来。事物的本来即道。作为本来的道,即本、即生。作为本的道是某种可能性,故不可说。作为生的道,未能成形,故不可说。道不可道。假的有、巧的真、善的名都遮蔽了道：事物的本来。故需要反,即还原。     

论亚里士多德的善

善是存在的本体。它是幸福。最完美的幸福是沉思。对于这种活动,人们不能够言说（称赞）。善是好。好是主体的私意的表达。这意味着善依据于主体的自愿、私意,并能够带来欢乐。善是真它陈述了现象的关系。真仅仅关注现象而不是作为存在的真正的善因此,真的善其实并不真。     

Practical Skepticism and the Reasons for Action

There is nearly universal agreement that coercion is an evil. Even when it is necessary to avoid a greater evil or to attain some good, it is still a necessary evil. There is also nearly universal agreement that, other things being equal, one ought not to exercise coercion. Here the agreement ends. There is little agreement about just when coercion is justified. More surprisingly, there is little agreement about what coercion is. This latter controversy is more fundamental, and this paper is an attempt to shed some light on it.     

ONTOLOGICAL NATURALISM*

Abstract: Ontological naturalism is the view that our best construal of what there is, is what science says there is. This paper argues that while such a doctrine is very appealing, unfortunately, determining what there is, is neither as simple, nor as straightforward, as ontological naturalism would have it seem. Determining what there is, it is claimed, involves three steps. First, one must decide which part of scientific discourse should be taken as true. One must then regiment that part of scientific discourse, and finally, one has to apply a criterion for ontological commitment to that regimented discourse. This paper will concentrate on the first and third of these tasks. It is argued that resolving the tasks these steps put before us requires the employment of philosophical maneuvers, that is, maneuvers that neither originate within, nor are ratified by, the practice of science. But these are maneuvers that the ontological naturalist is not entitled to. Thus, ontological naturalism is not a feasible doctrine.     

The Virtue of Epistemological Dualism

The article tries to answer the following question: what is the most promising epistemological strategy if my objective is the construction of a theory which gives me the opportunity to decrease the risk of getting to what is actually absolute, that is, to irreversible negative actions (irreversible as a theory might not be, but as an action often is)? The answer proposed is a form of epistemological dualism which means that I metaphysically believe (that is, I programmatically and systematically believe, without certainly knowing it) that the epistemological relationship between any theory and any reality is dualistic. More specifically, I metaphysically believe that the epistemological relationship between any theory and any reality is not saturated: in any theory there is an ideal error, because there is no theory which is totally saturated by reality, and any reality can actualize the ideal error, because there is no reality which is totally saturated by theory.     

Men Under Scrutiny

It is a burning of the heart that I want; it is this burning that is everything, more precious than the empire of the world, because it calls God secretly in the night. —Rumi

A man who is not on fire is nothing; he is ridiculous, he is two-dimensional. He must be on fire even if he does make a fool of himself. A flame must burn somewhere, otherwise no light shines, there is no warmth, there is nothing. —C.G. Jung     

波函数的实在性分析

波函数是量子力学的核心概念。波函数的实在性问题一直是科学实在论与反实在论争论的焦点之一。20世纪上半叶量子力学研究主要是检验量子力学的理论是否正确或完备,仅有少量量子技术产品问世。1935年爱因斯坦、波多尔斯基和罗森(EPR)发表的《能认为量子力学对物理实在的描述是完备的吗?》一文,提出了EPR关联——量子纠缠,直接引发了对量子力学基本问题的论争。(Einstein,Podolsky and Rosen,pp.777-780)基于EPR量子纠缠,1993年本内特(Bennett)等6位科学家在《物理评论快报》发表题为《经由经典和EPR通道传送未知量子态》的重要论文,引发了一系列有关量子信息与量子技术的研究,形成了量子信息理论、量子控制论、量子技术等新的量子科技理论。量子纠缠     

It's Personal—Or Not At All: On God as Love/r

Abstract : Henriksen discusses what it means that God is personal, with special regard to the claim that God is love. If God is love, God must be understood as personal. This approach is related to different elements concerning human life and human freedom, and how to engage in human life. Also the radical alternative is suggested: instead of understanding God as love, the alternative is considered that death is God (as the final and strongest power there is). This alternative shows that it is the most likely interpretation of actual human conduct to opt for the alternative that God is love. Hence, to understand God as love is part of what it means to relate humanely and with hope to what is taking place in human life.     

Responsibility,Reaction, and Value

Many writers accept the following thesis about responsibility: (R) For one to be responsible for something is for one to be such that it is fitting that one be the object of some reactive attitude with respect to that thing. This thesis bears a striking resemblance to a thesis about value that is also accepted by many writers: (V) For something to be good (or neutral, or bad) is for it to be such that it is fitting that it be the object of some pro-attitude (or indifference, or some contra-attitude). V has been the subject of intense debate in recent years, in part because of its incorporation into what has come to be called the “buck-passing” account of value. In particular, V is open to three challenges: that it is not necessarily the case that whatever is good is the fitting object of a pro-attitude; that it is not necessarily the case that whatever is the fitting object of a pro-attitude is good; and that, even if there is a strict equivalence between what is good and what is the fitting object of a pro-attitude, still the former is not to be analyzed in terms of the latter. The resemblance between V and R has not been previously commented on, but, once it is recognized, it is clear that R is open to challenges that resemble those to which V is vulnerable. This paper explores both the challenges to V and the parallel challenges to R and discusses responses that may be given to these challenges. The interrelation between V and R is then examined, and a general lesson is drawn concerning how to adjudicate disputes about the nature of moral responsibility.     

Sinnott-Armstrong,Walter, ed., Moral Psychology Volume 2. The Cognitive Science of Morality: Intuition and Diversity,Cambridge, Mass.: MIT Press, 2008, pp. xviii + 585, US$30 (paper)

It is plausible that the universe exists: a thing such that absolutely everything is a part of it. It is also plausible that singular, structured propositions exist: propositions that literally have individuals as parts. Furthermore, it is plausible that for each thing, there is a singular, structured proposition that has it as a part. Finally, it is plausible that parthood is a partial ordering: reflexive, transitive, and anti-symmetric. These plausible claims cannot all be correct. We canvass some costs of denying each claim and conclude that parthood is not a partial ordering. Provided that the relevant entities exist, parthood is not anti-symmetric and proper parthood is neither asymmetric nor transitive.     

EUTHYPHRO AND THE GOODNESS OF GOD INCARNATE

A familiar problem is here viewed from an unfamiliar angle. The familiar problem is the Euthyphro dilemma: if God wills something because it is good, then goodness is independent of God, so God becomes, morally speaking, de trop. On the other hand, if something is good because God wills it, then, given the absence of constraint on what God may will, moral truths are – counterintuitively – contingent. An examination of the kinds of necessity and possibility at work in this conundrum leads us to the most promising solution: there is a metaphysical connection between God and goodness. What he wills is an expression of his nature. But (and this is the unfamiliar angle), that solution now poses an acute problem for an understanding of the Incarnation. For if God is constitutive of goodness, and Christ is God incarnate, then Christ is constitutive of goodness. But Christ, as a human, is subject to external moral evaluation and obligation, which entails that he is not constitutive of goodness. This metaethical difficulty is not easily met by the usual strategies by which Christ is understood to have two natures. Reflection on our moral relations to our past selves, however, suggests a way forward.     

A coefficient alpha for test-retest data

Transient errors are caused by variations in feelings, moods, and mental states over time. If these errors are present, coefficient alpha is an inflated estimate of reliability. A true-score model is presented that incorporates transient errors for test-retest data, and a reliability estimate is derived. This estimate, referred to as the test-retest alpha, is less than coefficient alpha if transient error is present and is less susceptible to effects due to item recall than a test-retest correlation. An assumption underlying the test-retest alpha is essential tau equivalency of items. A test-retest split-half coefficient is presented as an alternative to the test-retest alpha when this assumption is violated. The test-retest alpha is the mean of all possible test-retest split-half coefficients.     

Temporal Predication with Temporal Parts and Temporal Counterparts

If ordinary objects have temporal parts, then temporal predications have the following truth conditions: necessarily, (a is F) at t iff a has a temporal part that is located at t and that is F. If ordinary objects have temporal counterparts, then, necessarily, (a is F) at t iff a has a temporal counterpart that is located at t and that is F. The temporal-parts account allows temporal predication to be closed under the parthood relation: since all that is required to be F at t is to have a temporal part, a t, that is located at t and that is F, every object that has a t as a temporal part is F at t. Similarly for the temporal-counterparts account. Both closure under parthood and closure under counterparthood are shown to have unacceptable consequences. Then strategies for avoiding closure are considered and rejected.     

Cognition and motivation in emotion

The role of cognition--and to some extent motivation--in emotion, the ways meaning is generated, unconscious appraising, and the implications of this way of thinking for life-span development are addressed. It is argued that appraisal is a necessary as well as sufficient cause of emotion and that knowledge is necessary but not sufficient. This position is examined in light of what is known about emotions in infants and young children, the effects of drugs on acute emotions and moods, and recent patterns of thought about the brain in emotions. The discussion of how meaning is generated is the core of the article. Automatic processing without awareness is contrasted with deliberate and conscious processing, and the concept of resonance between an animal's needs and what is encountered in the environment is examined. The idea that there is more than one way meaning is achieved strengthens and enriches the case for the role of appraisal in emotion and allows the consideration of what is meant by unconscious and preconscious appraisal and the examination of how they might work.     

Does Vagueness Exclude Knowledge?

On two standard views of vagueness, vagueness as to whether Harry is bald entails that nobody knows whether Harry is bald—either because vagueness is a type of missing truth, and so there is nothing to know, or because vagueness is a type of ignorance, and so even though there is a truth of the matter, nobody can know what that truth is. Vagueness as to whether Harry is bald does entail that nobody clearly knows that Harry is bald and that nobody clearly knows that Harry is not bald. But it does not entail that nobody knows that Harry is bald or that nobody knows that Harry is not bald. Hence, the two standard views of vagueness are mistaken.     

Within my breast, alas, two souls ...

The obsession is pursued of a word, a sign, a thought that is identical with the thing it signifies, where there is no space between the two. And the nightmare is entertained that, if such an identity is not attained, then intellectual work in general is worth nothing and should be destroyed.     

Quine's Nihilism

Quine is an important philosopher. The point of departure of his philosophical enterprise is sound: his down to earth naturalism, his scientism and behaviourism. However, he tends to get carried away by it, when he goes to extremes – and ends up in nihilism. It is certainly true that we can never quite rule out the possibility that we have misunderstood another person. And what he or she means is a consequence mainly of two things. It is a consequence of his actual intention with the utterance and also, to some extent, of the way the world actually is. This is not to say, however, that there is no fact of the matter. While there is underdetermination by actual evidence of interpretation there is no such thing as indeterminacy of translation (or interpretation). While there may well exist conflicting empirically adequate theories, there is no room for ontological relativity. Some of these theories may be the right one and the others wrong, even if this is something we cannot even in principle decide on empirical grounds.     

Varieties of graded forgetting

Forgetting is typically viewed as counterproductive in everyday life. However, it may mainly be harmful when it is complete, that is, all-encompassing and permanent, and not when it is graded, that is, partial and fluctuating. I propose that forgetting is in fact mostly graded, and that this is an essential reason that it is often helpful. I delineate three ways in which forgetting may be graded. First, it may occur with respect to one, but not another, part of a memory. Second, it may occur in one context, but not in another. Third, forgetting may be present at one point in time, but not at another. Also, I propose that different levels of forgetting are possible, based on whether an engram or a context is unavailable, silent, restricted, latent, or potent. Overall, I hypothesize that forgetting is often helpful because it can be flexible and tailored to the circumstances.
