In this excellent book, Christoph Kelp and Mona Simion defend an etiological-functionalist account of the normativity of assertion. Specifically, the etiological function of assertion is to generate knowledge in hearers. Kelp and Simion argue that this functionalist thesis has two important implications: a) that epistemically good assertions are those that are disposed to generate knowledge in hearers, and b) that epistemically permissible assertions are those that conform to the Knowledge Rule of Assertion (KRA). One important feature of the book is a sophisticated defense of KRA by means of an etiological-functionalist framework.The book is lucidly written, rigorously argued, informed, and original. All of this is as expected, coming from two authors who have already made significant contributions to the topic. Indeed, the book draws on both their single-authored and coauthored work on related issues, including the normativity of assertion, the epistemology of testimony, epistemic norms, and epistemic normativity. The result is that an etiological-functionalist account of assertion is now front and center among competing views.The book also contains several other interesting and original discussions, all by way of applying the authors’ etiological-functionalist framework to prominent issues in the literature on assertion and beyond. These include a chapter on epistemic injustice (defending a duty to believe on the part of hearers), a chapter on whether there is a constitutive rule of assertion (rejecting Williamson’s strong constitution thesis, but defending a weaker version), a chapter on contextualism (arguing, contra DeRose, that KRA counts against a contextualist semantics of knowledge attributions), and an appendix on the value of knowledge (offering an original defense of our concern with knowledge, as well as a functionalist account of knowledge’s value). In my judgment, the book advances discussions on all of these topics in important and original ways.In the remainder of the review, I clarify what Kelp and Simion mean by a functionalist account of assertion, and I review what I take to be the authors’ most interesting arguments in favor of KRA and their etiological-functionalist account. I end by raising some questions about the view that results.Kelp and Simion tell us that they are arguing for a “function first” account of the normativity of assertion. Three points of clarifications are important here. First, this an account of the epistemic normativity of assertion, that is, an account of what makes an assertion epistemically (as opposed to practically, morally, or all-things-considered) good, proper, or right. Second, by “function,” the authors mean etiological function. This makes their account a competitor with ones that ground the normativity of assertion in human intentions (or what I will call the intended function of assertion). For example, it is a competitor with accounts that ground the normativity of assertion in human in
)那么,通过他们自己的推理,Kelp和Simion应该认为断言的功能是传递知识,而正是履行这一功能的倾向使得象征性断言是好的。第二,FFAA应该对断言的认知良善给出一个完整的解释还是部分的解释?如果它应该给出一个完整的账户,那么FFAA是不可信的。这是因为断言似乎既有预期功能,也有病因功能,预期功能的实现也有助于断言的认知良善,这似乎是合理的。例如,许多作者都认为,断言的言语行为是由传递知识、给出相信的理由或给予相信的许可的意图构成的。如果是这样,那么断言的认知良善至少在一定程度上是实现了其预期的认知功能。那么,假设FFAA被认为只给出了断言的认知良善的部分说明。在这种情况下,尚不清楚为什么FAA是“预期功能”解释的竞争对手,包括那些将断言的善良建立在构成规则、语言规范或管理断言实践的其他社会规范中嵌入的认知意图中的说法。假设Kelp和Simion要修改他们的观点以适应这些担忧。他们的许多论点和观点都将原封不动地保留下来,包括他们对KRA的功能主义辩护。我们仍然会有一个令人信服的(现在是部分的)关于断言的好处的解释,就断言传递知识的病因功能而言。

Epistemic Explanations: A Theory of Telic Normativity, and What it Explains 认识论解释:一种目的性规范理论及其解释

A new book by Ernest Sosa is always an event. In a philosophical age where much of the focus is on piecemeal issues, Sosa has forged ahead with a novel virtue-theoretic treatment of a range of core questions in epistemology that is self-consciously systematic. Note that ‘epistemology’ is here broadly conceived. Indeed, a key part of the Sosa project has been to enlarge the reach of mainstream epistemology and thereby draw out connections with other areas of philosophy that have hitherto been underexplored, especially ethics, philosophy of mind and action, and metaphysics. Moreover, Sosa is also unusual among contemporary philosophers in having an acute grasp of the history of the subject, which he brings to bear in support of his program. The result is an incredibly sophisticated vision of how a range of topics in epistemology fit together.1Epistemic Explanations: A Theory of Telic Normativity, and What it Explains is the new installment in Sosa’s distinctive brand of virtue epistemology. The book is organized into four parts. Part 1 is devoted to articulating the telic virtue epistemology framework that Sosa defends. In light of this framework, he explores how we should account for the undoubted importance of first-hand knowledge and understanding and how we should conceive of the relationship between the theory of knowledge and intellectual ethics. Part 2 offers a comprehensive treatment of the epistemology of suspension. Part 3 is primarily concerned with default assumptions and understanding how they lead to refinements of telic virtue epistemology. Among other things, this part defends a metaphysical hierarchy of epistemic categories that includes a discussion of what Sosa terms secure knowledge, which is a particularly important epistemic category within his framework. Part 4 builds on the account of default assumptions in part 3 by offering an extended discussion of how this bears on the Wittgenstein–Moore debate (roughly, the clash of hinge epistemology with a form of epistemic foundationalism). Like all Sosa’s work, the writing is refreshingly crisp. It is also deceptively readable, in that one can find oneself surprised at just how much philosophical ground is being covered.There is much that I agree with in this book, but I would like to take this opportunity to critically focus on Sosa’s intriguing appeal to default assumptions and how it plays out both in terms of his theory of knowledge and his approach to radical skepticism. As will be familiar to readers of Sosa’s work, he understands knowledge in terms of what he calls aptness. Roughly, a performance is apt (‘accurate because adroit’) when one’s success in the target endeavour is properly attributable to one’s manifestation of relevant skill. As applied to the epistemic realm, we thus get the idea that knowledge is apt belief—that is, one knows when one’s cognitive success (true belief) is properly attributable to one’s manifestation of relevant cognitive agency.2Sosa’s novel cla
我们所需要做的就是有原则地描述如何从不相关的选项中区分出相关的选项。在这方面,人们提出了各种各样的建议,例如从错误可能性的模态接近度、会话显著性等方面进行描述。索萨在这个话题上提出了他自己的观点,他认为恰当的表现,因此恰当的信念,可以合理地涉及假设默认假设,即使这些假设涉及模态接近的错误可能性,也是如此。只要预设的假设是错误的,并且受试者没有被给予接受这些假设的具体理由,那么她仍然可以表现出恰当的信念,从而获得知识。此外,索萨从这一点上明确地得出了一个反怀疑主义的道德,他声称日常知识可以合理地与我们的默认假设共存,即激进的怀疑假设是错误的。正如他所说,“足够认真,没有疏忽或鲁莽,我们通常假设自己没有怀疑的情况。”这种假设是正确的,即使是在极少数情况下,当它是正确的,但不知道是正确的,甚至是相当不安全的”(159)。请注意,在采取这条路线时,索萨正在接受被许多人认为是相关替代理论(一个直截了当的版本)的不幸后果,即否认知识的封闭原则毕竟,一个人现在可以知道日常的主张,并充分意识到它们包含了对激进怀疑假设的否认,但仅仅假设这些否认是错误的。索萨还提出了一个进一步的主张,据我所知,没有其他相关替代理论的支持者提出过(至少没有明确提出过),那就是,一个人的知识可能是不安全的,因此也不会失去真实性。特别是,由于背景假设只是幸运地为真,因此很容易是假的,这与一个人对目标命题的知识是相容的,并且由于这些背景假设的虚假性可以使一个人对目标命题的信念是假的,那么他对已知目标命题的信念只能是幸运地为真(即,它很容易是假的)。我认为索萨说得很对,一般来说,恰当的表现与不安全是相容的;事实上,我认为这是对索萨作品的深刻见解。正如我们所指出的那样,成就(即由于能力或Sosa术语中的恰当表现而获得的成功)可能在模式上是脆弱的(即目标成功可能很容易失败)。索萨在这里指出了问题的根源:对恰当的表现来说,重要的是合理的背景假设是正确的——特别是,它们是否幸运地正确并不重要。这就是为什么外野手的出色表现与球场的灯光很容易熄灭的事实是一致的(在这种情况下,他的接球尝试可能会出错)。我与索萨的不同之处在于,我不认为知识也是如此。也就是说,如果一个人的认知成功(真正的信念)很容易失败,那么它就不是知识。知识排除了这种运气(脆弱性),因为它排除了高水平的认知风险(即,一个人的信念是错误的认知风险)。这就是为什么,当一个人知道的时候,他的信仰基础是这样的,他不可能轻易出错,这是安全所要求的。相比之下,索萨提出的另一种图景将使我们允许知识与高水平的认知风险共存。结论是,知识不是恰当的信念(相对而言,知识不是一种认知成就)。即使我们同意索萨的观点,即恰当的信念(或认知成就),即使在不安全的情况下,也可以等同于知识,我们也不清楚这是否能像他所假设的那样,让我们对激进怀疑主义的问题有所了解。想想他的观点意味着什么。我们可以认识到,我们的日常知识预设了我们永远无法(即使在原则上)排除的全局错误可能性的虚假性,但我们仍然满足于继续,就好像我们有知识一样。只要怀疑的情景实际上没有出现(即使它们可以很容易地出现),那么我们的信念就可以恰当地形成,即使我们毫无根据地假设我们没有根本错误,因此可以算作知识。与此相关,与拒绝封闭性一致,一个人可以自觉地意识到,他知道自己对日常命题有知识,他知道这些命题包含了对怀疑假设的否认(例如,他有手),而无法知道所包含的命题(例如,他不是一个BIV)。虽然我觉得索萨在认识论上的总路线非常有说服力,但我觉得他在激进怀疑主义上的路线非常没有说服力。

Averroes on Intellect: from Aristotelian Origins to Aquinas’s Critique 阿威罗伊论智力:从亚里士多德的起源到阿奎那的批判

There have been philosophers who sought to preserve and ratify the dictates’ common sense, and there have been philosophers who were willing to overturn and correct those dictates. And then there was Averroes. His most notorious doctrine is not just counterintuitive. It commits him to something that seems self-evidently false, namely that there is only a single mind to which all human thought is related. As his most famous critic, Thomas Aquinas, pointed out, it seems simply obvious that we each have a mind of our own, and that we can each think as individuals. Averroes—to use the Latinized version of his name, Ibn Rushd—seemed to deny this in his Long Commentary on Aristotle’s On the Soul, triggering a protracted debate in Latin medieval and Renaissance philosophy.1 Why spill so much ink over such an implausible theory? Part of the reason was surely Averroes’s stature as the most authoritative commentator on Aristotle. When Aquinas devoted a treatise specifically to the issue, he met Averroes on his own ground by disputing the unity theory as an interpretation of On the Soul. His concern was not mainly to refute a false philosophical view, but to rescue Aristotle from being associated with that view.And there was another reason the topic attracted so much attention: Averroes’s arguments for the unity of intellect were surprisingly powerful. Just how powerful is shown in a superb new book by Stephen Ogden. Applying the sort of sympathetic approach and analytic acuity now standardly brought to the works of Aristotle himself, Ogden explains that Averroes had strong philosophical and exegetical reasons for endorsing the unity of the intellect. With regular reference to Aquinas as a foil, Ogden makes a convincing case that Averroes’s apparently unbelievable view in fact made a great deal of sense within an Aristotelian framework. Indeed, within that framework it often seems to be at an advantage against the apparently far more plausible view of Aquinas, for whom intellect is immaterial but individual: one mind per human, not one mind for the whole human race.Averroes’ position was, as he noted himself, unique within the complex history of interpretations of Aristotle’s On the Soul chapters 3.4–5, the chapters that deal most centrally with intellect. Ogden indeed says that the Averroist view “boasts novelty galore” (92). But it was actually not new to posit a single mind standing over all human individuals. The Aristotelian God was such a mind, as was the nous postulated by Plotinus. Closer to Averroes in time, culture, and intention was Avicenna (again, this name is a Latinization, in this case of Ibn Sīnā). He held that the so called “active intellect” (AI) described by Aristotle in the brief and inscrutable chapter 3.5 of On the Soul is a single transcendent principle that somehow allows individual humans to think. (Exactly how it does so is a matter of extensive dispute among Avicenna scholars.) By contrast, the potential or material intellect (MP
有哲学家试图保留和认可命令的常识,也有哲学家愿意推翻和纠正这些命令。然后是阿威罗伊斯。他最臭名昭著的学说不仅仅是违反直觉。它使他陷入一种似乎不证自明的错误,即只有一个心灵与人类的一切思想有关。正如他最著名的批评家托马斯·阿奎那(Thomas Aquinas)所指出的那样,似乎很明显,我们每个人都有自己的思想,我们每个人都可以独立思考。阿威罗伊——用他名字的拉丁化版本,伊本·拉什——似乎在他对亚里士多德的《论灵魂》的长篇评论中否认了这一点,引发了拉丁中世纪和文艺复兴时期哲学史上一场旷日持久的辩论为什么要在这样一个不可信的理论上花那么多笔墨呢?部分原因肯定是阿威罗伊作为最权威的亚里士多德评论家的地位。当阿奎那专门为这个问题写了一篇论文时,他在自己的立场上遇到了阿威罗伊,他争论统一理论作为《论灵魂》的解释。他关心的主要不是驳斥一个错误的哲学观点,而是拯救亚里士多德,使其不与那个观点联系在一起。这个话题吸引如此多关注还有另一个原因:阿威罗伊关于智力统一性的论证令人惊讶地有力。史蒂芬·奥格登(Stephen Ogden)的一本出色的新书展示了这种力量有多强大。奥格登运用了亚里士多德自己的作品中通常采用的那种同情的方法和敏锐的分析能力,他解释说,阿威罗伊有强大的哲学和训诂上的理由来支持智力的统一性。奥格登经常引用阿奎那作为衬托,提出了一个令人信服的例子,即阿威罗伊表面上令人难以置信的观点,实际上在亚里士多德的框架内是有很大意义的。事实上,在这个框架内,它似乎经常比阿奎那的观点更有优势,阿奎那认为智力是非物质的,而是个体的:每个人都有一个头脑,而不是整个人类的一个头脑。阿威罗伊的立场,正如他自己所说,在亚里士多德《论灵魂》第3.4-5章的复杂历史解释中是独一无二的,这几章主要是关于智力的。奥格登确实说过,阿威罗伊主义的观点“拥有丰富的新颖性”(92)。但事实上,假设一个单一的思想凌驾于所有人类个体之上并不是什么新鲜事。亚里士多德的上帝就是这样一种精神,就像普罗提诺所假定的诺斯一样。在时间、文化和意图上更接近阿威罗伊的是阿维森纳(同样,这个名字是拉丁化的,在伊本·s·纳伊的例子中)。他认为,亚里士多德在《论灵魂》简短而晦涩的第3.5章中所描述的所谓“主动智能”(AI)是一种单一的超越原则,它以某种方式允许个体人类思考。(它究竟是如何做到这一点的,在阿维森纳的学者之间存在广泛争议。)相比之下,负责接收可理解信息的潜在智力或物质智力(MPI)对阿维森纳来说是每个人类智力所独有的。正如奥格登所言,阿威罗伊和阿奎那一致认为,人工智能和MPI之间的这种不匹配是不可持续的。要么两者都是独立的,要么两者都是一体的。阿奎那当然采纳了前者的观点,而阿威罗伊则反对后者。为什么?在阅读奥格登的书之前,我认为阿威罗伊的立场的一个主要原因是物质是个性化的原则。例如,两朵向日葵属于向日葵的种类,但它们的形式是个性化的,因为它们被接收在两个时空不同的物质中。但亚里士多德明确指出,智力是一种非物质的力量。因此,没有什么可以区分不同的个体智力。然而,奥格登提出了一个令人信服的案例,证明这不是阿威罗伊主义理论背后的论点(98-100)。毕竟,与天界有关的智慧同样是非物质的,然而它们设法彼此区别开来。它们可能在某种程度上有所不同,这对于个体的人类智力来说是不可能的,但这需要进一步的论证。因此,当阿威罗伊认为MPI是一种确定的、非物质的实体时,这本身就留下了一个问题,即是否存在一个这样的智力或多个这样的智力(105-8)。事实上,阿维森纳用了一个很像阿威罗伊的论点来证明MPI的非物质性,同时认为每个人都有自己的MPI。因此,虽然奥格登承认,对个性化的关注可能有助于提出一个统一理论,而且肯定会给阿奎那的观点(见220页)带来问题,但他认为,阿威罗伊主义理论最好以另一种方式得到证明。这是通过他所谓的“统一论证”来实现的,该论证指出,“解释我们如何都能思考同一件事的最好方法是,在一个智力中,只有一件事是被思考的”(109)。 正如奥格登所言,似乎亚里士多德学派的阿威罗伊在这里沉迷于柏拉图主义的直觉(113)。当你我都理解了向日葵的形态,我们就应该抓住同一个思想对象。但阿威罗伊认为,一个可理解的对象必须始终存在于心灵中,而不是像柏拉图式的形式那样独立存在。由此可见,所有可理解的东西都是在一个人的头脑中接受的。唯一的选择是说你对向日葵有一种理解,而我对向日葵有另一种理解。但这样一来,我们实际上就不会在思考同一件事,或者,我们可以说,"有同样的想法"这就给阿威罗伊留下了一个问题:如何解释为什么我们似乎在以个体的方式思考。事实上,这并不是唯一的问题。奥格登在这里提出了另一个很好的观点,即困难不仅是现象学的,而且是本体论的(166)。人类个体应该是思考的主体,我们认为这是事实,这就是本体论主张的证据。当阿奎那在他反对阿威罗伊关于智力统一性的论文中提出这一反对意见时,他反复挑战阿威罗伊主义者解释“这个人思考(hic homo intelligit)”(McInerny 1993)这一事实时,这一反对意见在两个层面上都起作用。现代的诠释者试图代表阿威罗伊回答这个问题。一般来说,他们想要表明,在某种意义上,每个人都是阿威罗伊的智力思维的主体,例如,通过某种单一智力的统一,或者因为我们较低的认知活动为这种智力提供了必要的基础。因此,当我记忆中的向日葵形象被单一的智力用来思考向日葵的可理解形式时,在我看来,我似乎是一个从事思考的人。奥格登认为这也许可以解释现象学上的表象,即我在思考。但当涉及到反对的本体论版本时,他认为阿威罗伊会咬紧牙关。他会承认,严格地说,没有人能够理解或思考普遍可理解的对象。只有一个聪明的人才会这么做。智力存在于个体人类认知之外,这就是为什么它只能以一种模棱两可的方式被称为“灵魂”(51 - 2,184)。因此,奥格登把“错误理论”归于阿威罗伊(174),根据这一理论,我们错误地认为自己在从事真正的思考,而实际上我们并没有。具身人类所能做的最多的是处理抽象或“模糊”的个人形象,这些形象近似于普遍的可理解性,而不是完全实现它(199)。所以事实证明,你和我确实对向日葵有自己的看法,这些看法来自于我们对特定向日葵的不同体验。向日葵只有在单一的智力水平上才有单一的思想。奥格登礼貌而坚定地批评了其他学者试图逃避这一结论的尝试,例如,他说,在智力和个体人类之间存在某种形式的统一(正如理查德·c·泰勒(Richard C. Taylor) 2013年所强调的那样,单一的智力将是“我们的形式”)。奥格登认为,这是正确的,因为在智力和个人之间存在一种有效的统一(205)。但是,智能使用我大脑中的记忆和想象图像这一事实显然并不意味着我就是智能,就像一台在线服务器与我的笔记本电脑并不相同,因为它使用的是从我的笔记本电脑硬盘上上传的数据(我的类比,不是奥格登的,尽管他使用了类似的类比)。如果智力是人类的实体形式,那么它将与人类个体相同(174),但显然不是这样,因为它不可能同时是我的实体形式和你的实体形式。虽然我猜一些现代的阿威罗伊专家可能会对这种阅读犹豫不决,但奥格登能够指出中世纪和文艺复兴时期的思想家对阿威罗伊有着同样的无拘无束的理解。他至少把解释的责任放在了阐释者

Perception solves computationally demanding problems at lightning fast speed. It recovers sophisticated representations of the world from degraded inputs, often in a matter of milliseconds. Any theory of perception must be able to explain how this is possible; in other words, it must be able to explain perception’s computational tractability. One of the few attempts to move toward such an explanation is the information encapsulation hypothesis, which posits that perception can be fast because it keeps computational costs low by forgoing access to information stored in cognition. I argue that we have no compelling reason to believe that encapsulation explains (or even contributes to an explanation of) perceptual tractability, and much reason to doubt it. This is because there exist much deeper computational challenges for perception than information access, and these threaten to make the costs of access irrelevant. If this is right, it undermines a core computational motivation for encapsulation and sends us back to the drawing board for explanations of perceptual tractability.
感知以闪电般的速度解决计算要求很高的问题。它从退化的输入中恢复复杂的世界表征,通常在几毫秒内。任何知觉理论都必须能够解释这是如何可能的;换句话说,它必须能够解释感知的计算可追溯性。为数不多的尝试之一是信息封装假说,该假说认为,感知之所以能够快速,是因为它通过放弃对存储在认知中的信息的访问,使计算成本保持在较低水平。我认为,我们没有令人信服的理由相信封装解释了(甚至有助于解释)感知可追溯性,而且有很多理由怀疑它。这是因为与信息访问相比,感知存在更深层次的计算挑战,而这些挑战可能会使访问成本变得无关紧要。如果这是正确的,它破坏了封装的核心计算动机,并将我们送回绘图板,以解释感知可追溯性。

Everybody knows (for the relevant value of ‘everybody’) that, for Thomas Aquinas, perfect happiness consists in intellectual contemplation of the divine essence, with the will’s delight or enjoyment being a necessary concomitant of that beatific vision but not, strictly speaking, part of the essence of happiness. Beyond this boilerplate statement, however, most of us would be hard-pressed to say much more about contemplation in Aquinas. What sort of act is it, and how does it relate to other acts of intellect? What acts of contemplation are available in this present life, and how do those acts fit into a life of faith or a life devoted to philosophical or theological study? What contribution, if any, does contemplation make to this-worldly happiness? In Thomas Aquinas and Contemplation, Rik Van Nieuwenhove takes up these and related questions and develops Aquinas’s account of contemplation in a systematic way, elaborating even what “everybody knows” in unexpected directions and unearthing important but neglected material. There are even some surprises along the way.Van Nieuwenhove notes that although Aquinas identifies contemplation as the goal or end of human life, he nowhere offers a precise definition of contemplation. In fact, he speaks of contemplation in a variety of ways and contexts, ranging from the perfect vision of God in the next life, through theoretical contemplation in this life, whether theological or philosophical, all the way to the insight that ordinary Christians can have—and indeed are called to have—into divine truth. What unites all these varieties of contemplation, Van Nieuwenhove argues, is that they culminate in “a non-discursive moment of understanding (intuitus simplex), a simple intellective insight into truth, (what is sometimes called an Aha-Erlebnis in German)” (16). In theological and philosophical contemplation, such nondiscursive insight is the hard-won result of a discursive process; in the contemplation that characterizes the ordinary Christian life, by contrast, it arises directly out of a divinely granted kinship (“connaturality”) between the believer and “the deep things of God” (1 Corinthians 2:10). It is an advantage of this broad understanding of contemplation as intuitus simplex that it “can incorporate the acts of contemplation of the Greek sage, as well as those of the vetula who enjoys the benefit of her Christian faith” (47–48).This vetula (Van Nieuwenhove leaves the word untranslated; it means “little old woman”) has a minor recurring part in the book, as she has in Aquinas’s own writing. In his sermon on the Apostles’ Creed, Aquinas writes that “not one of the philosophers before the coming of Christ, however hard they tried, could know as much about God and about what is necessary for eternal life as one vetula after the coming of Christ can know through faith” (In symbolum apostolorum, pr.; all translations of Aquinas are my own). In his sermon Attendite a falsis, Aquinas writes:The vetula may n
每个人都知道(因为“每个人”的相关价值),对托马斯·阿奎那来说,完美的幸福包括对神圣本质的理智思考,而意志的愉悦或享受是这种美好愿景的必要伴随物,但严格地说,不是幸福本质的一部分。然而,除了这句陈词滥调之外,我们大多数人都很难对阿奎那的沉思多说些什么。这是一种什么样的行为,它与其他智力行为有什么关系?在现在的生活中有哪些沉思的行为,这些行为如何适合信仰的生活或致力于哲学或神学研究的生活?如果有的话,沉思对现世的幸福有什么贡献?在《托马斯·阿奎那与沉思》一书中,里克·范nieuwenhove接受了这些和相关的问题,并以系统的方式发展了阿奎那对沉思的描述,甚至在意想不到的方向上详细阐述了“每个人都知道”的东西,并发掘了重要但被忽视的材料。一路上甚至还有一些惊喜。范nieuwenhove注意到,虽然阿奎那认为沉思是人类生活的目标或终点,但他没有给出沉思的精确定义。事实上,他以各种不同的方式和背景来谈论沉思,从对上帝来生的完美想象,到今生的理论沉思,无论是神学的还是哲学的,一直到普通基督徒能够拥有的——实际上是被召唤去拥有的——对神圣真理的洞察。凡·Nieuwenhove认为,将所有这些不同的沉思统一起来的是,它们的高潮是“一个非话语的理解时刻(intuitus simplex),一个对真理的简单的理性洞察(有时在德语中称为ah - erlebnis)”(16)。在神学和哲学的沉思中,这种非话语的洞察力是话语过程中来之不易的结果;相比之下,在普通基督徒生活所特有的沉思中,它直接产生于信徒与“神的深层事物”(哥林多前书2:10)之间的神圣授予的亲属关系(“自然”)。这种将沉思作为单纯直觉的广泛理解的优势在于,它“可以结合希腊圣贤的沉思行为,以及那些享受基督教信仰好处的女祭司的沉思行为”(47-48)。这篇短文(范nieuwenhove)没有翻译这个词;它的意思是“小老妇人”)在书中有一个次要的反复出现的部分,就像她在阿奎那自己的作品中一样。在他关于使徒信经的布道中,阿奎那写道:“在基督降临之前,没有一个哲学家,无论他们多么努力,都不能像基督降临之后的一个维特拉那样,通过信仰了解上帝和永生的必要条件。”所有阿奎那的译本都是我自己的)。在他的布道中,阿奎那写道:,vetula可能不是范nieuwenhove的理想例子,因为她在这两段中所说的认知显然是命题知识,而不是简单的直觉。Van Nieuwenhove从ST III, q. 27, a. 5, ad . 3中找到了一个更好的例子,“阿奎那写道圣母玛利亚享受‘在沉思中使用智慧’……但不是‘在教学中使用智慧’”(4n)。无论“普通”基督徒沉思的最好例子是什么——我指的是“对神圣真理的开放或接受,这应该是基督徒生活的特征”(198),这些基督徒要么没有,要么缺乏机会去锻炼,从事学术神学或哲学研究所需的智力——这种沉思的可能性需要重新思考一些“人人都知道”的关于阿奎那的幸福观的东西。正如范nieuwenhove所说,在最近的解释者中有一种近乎一致的解读,那就是阿奎那的“不完美的幸福”只是亚里士多德式的幸福——通过运用我们的自然力量在今生获得的幸福,可以通过哲学思考或有道德的公民活动来表达——而“完美的幸福”是一种幸福的愿景,一种只有在来世才能获得的幸福,只有通过超自然的礼物才能获得。亚里士多德对神学的沉思一无所知(至少不是在神学作为神圣教义的意义上);他当然不知道什么是“由慈善和美德塑造的生活”(13)。然而,在阿奎那看来,这两者都可以促成现世的或“不完美的”幸福,而且两者——就它们涉及“对神圣真理的沉思”而言——都是“幸福的早期阶段(inchoatio),从这里开始,在未来的世界中完成”(ST II-II, q. 180, a, 4)范nieuwenhove强调“这种连续性对神学家阿奎那来说并非没有意义,对他来说,恩典使自然完美,但没有废除它”是正确的(47)。 在导论一章之后,范nieuwenhove在第一部分中列出了他阅读阿奎那关于沉思的认识论和形而上学基础。第二章专门讨论认识论问题,特别是智力的各种行为和沉思在其中的地位。关于阿奎那对新柏拉图主义来源的依赖而不是亚里士多德的讨论尤其有用。第三章更具试探性和思辨性,运用先验理论来理解沉思——这是阿奎那本人从未明确做过的,正如范nieuwenhove所承认的(49)。这里有一个重要的结论,根据第2章的认识论,是没有基础来解读阿奎那的神圣启示学说。正如范nieuwenhove所说,“真理在神的观念中有形而上学的基础,这一事实并没有使阿奎那陷入神学或光明主义的认识论观点”(59)。这一观察将我们带到了托马斯·阿奎那和沉思中一个重要的反复出现的主题:范nieuwenhove反对一些最近的学术,这些学术将阿奎那解释为“一个思想家,他的神学也许最好被贴上智慧的标签(例如J. P. Torrell, B. McGinn),奥古斯丁-光明主义者(约翰·米尔班克),甚至是有魅力的……[也就是]深受圣灵恩赐的影响(例如Servais Pinckers, Andrew Pinsent)”(18)。这些人的共同之处在于,他们都倾向于试图把阿奎那变成博纳文蒂尔,而范nieuwenhove的批判是尖锐的,有保证的,令人信服的,但总是有些仁慈。既然我已经简要地看了他对“光明主义”解读的拒绝,接下来我要转向智慧解读。我发现“智慧的智慧”这个概念一开始很令人困惑——毕竟,sapientia只是拉丁语中智慧的意思,那么智慧的智慧是什么呢?但范尼文霍夫解释说,它的意思是“一种品尝或品味的智慧”(174)。Sapientia确实来自动词sapio,意思是品尝或品味,阿奎那并不反对使用词源学来支持一个观点,只要它们符合他的目的。因此,更值得注意的是,阿奎那认为智慧和品味之间的词源联系无关紧要:“在拉丁语中可能是这样,但在其他语言中不是这样”(178,引用III Sent)。D. 35, q. 2, a. 1, qc。3、ad1;阿奎那使同样的观点在ST II-II, q. 45, a. 2, ad . 2)。在一般情况下,如范nieuwenhove显示,阿奎那抵制的想法,神学智慧本质上是有效的。即使是圣灵所赐的智慧,本质上也不是情感上的:它是认知上的,是一种神圣的智力提升,使其拥有者能够正确地判断神圣的事物。当然,这种恩赐根植于慈善,它属于意志,并赋予信徒一种与神圣事物的亲属关系或“自然”,以便她可以正确地判断,但这种恩赐本身属于智力(178-79)。这种恩赐并不是——现在我们转向对阿奎那的“魅力”解读——神学洞察力所必需的:“当然,神学家将理想地享受圣灵的恩赐,或者至少在道德上是正直的。受肉体欲望奴役的神学家在追求真理的道路上会受到阻碍。然而,阿奎那拒绝在神学的学术追求中赋予天赋一个重要的角色”(180)。这些批评,以及更多的积极的描述,都是在第三部分(“神学,基督徒生活和沉思”)中提出的。对这一讨论的丰富性作一个简短的回顾是不可能公正的。(特别值得注意的是,范nieuwenhove在第5章中解释了神学——更严格地说,sacra doctrina——是一门次于上帝自己的科学的科学的重要性,以及他在第7章中对阿奎那对圣灵恩赐作用的理解逐渐发

The Many and the One: A Philosophical Study of Plural Logic 多与一:多元逻辑的哲学研究
1区 哲学 Pub Date : 2023-04-01 DOI: 10.1215/00318108-10317593
J. P. Studd
Logicians and philosophers have had a good 120 years to get used to the idea that not every condition defines a set. One popular coping strategy is to maintain that each instantiated condition does at least determine a ‘plurality’ (i.e., one or more items). This is to say that friends of traditional plural logic accept—often as a trivial or evident or logical truth—each instance of plural comprehension: Unless nothing is φ, some things include everything that is φ, and nothing else. Set-theoretic paradoxes are avoided by recognizing a type distinction between singular quantifiers (‘something’) and plural ones (‘some things’).This book defends a heterodox version of plural logic. Salvatore Florio and Øystein Linnebo advocate a set theory based on a ‘critical plural logic’ that refutes many instances of plural comprehension. In particular, they deny that there are one or more things that include everything. Instead, they argue, when it comes to resolving the paradoxes, a ‘package deal’ that restricts plural comprehension to ‘extensionally definite’ conditions is more attractive than its competitors that either limit the range of our quantifiers (‘generality relativism’) or constrain ‘singularization.’ Florio and Linnebo’s rejection of traditional plural logic permits them to combine two otherwise incompatible views: (i) ‘the set of’ operation is a universal singularization, so that it injectively maps each plurality to an object (namely, its set), and (ii) the domain of ‘everything’ may contain absolutely everything, so that it cannot be surpassed by singularization.The argument for adopting critical plural logic in preference to traditional plural logic comes in the fourth and final part of the book. The first three parts make the authors’ case for taking plural resources seriously in the first place. Part I reappraises the debate between pluralism, ‘which takes plural resources at face value’ (2), and singularism, which takes the opposite view. Part II compares ‘four different ways to talk about many objects simultaneously’ (119), including second-order quantification, and the use of ‘individual sums’, in addition to sets and pluralities. Part III focuses on philosophical applications of plural logic. Along the way, the book tackles many other topics of interest, including whether plural logic counts as ‘pure logic’ (168), or carries distinctive ontological commitments (chap. 8), how plural resources interact with modality (chap. 10), and whether the pluralization operation can be iterated to obtain superplural terms the denote ‘pluralities of pluralities’ (180) (chap. 9).The Many and the One covers an impressive amount of difficult territory in an admirably clear and engaging way. Florio and Linnebo offer a fresh perspective on the pluralism debate and defend a novel response to the paradoxes. The driving force behind their arguments is usually logic, broadly construed, rather than linguistics or the philosophy of language. But Florio and Linneb
Florio和Linnebo试图通过我们对这些概念的直觉把握来激发这些公理(他们在10.10节中对此进行了解释)。例如,他们认为,“因为每一个单一的对象都可以被限定,所以存在单一的复数”(280)。在其他情况下,它们依赖于溯因性考虑。一个公理允许我们通过在一个定义函数下封闭任何复数来获得无限复数。这一公理的理由是,将无限集合视为外延确定已经取得了“巨大的理论成功”(282)。与允许进一步的多元形成操作的公理相结合,最终的结果是一个与标准集合理论ZFC非常相似的集合理论。我对这个论点有一点保留意见。假设我们对“限定”或“外延确定性”的把握足够牢固,足以证明弗洛里奥和林内博的公理是正确的。是什么阻止一个奇点主义者利用这个概念来直接激发符合ZFC一阶公式的类似集合形成操作?例如,奇点论者可能会说,“因为每一个单独的对象都可以被限定,所以就有单独的集合。”此外,由于他们在理论上的成功,她可以通过允许任何集合在一个定义函数下闭合而得到无限集。如果直接从外延确定性到集合,而不绕道复数,会失去什么?第二个论点,我想选择的目标是“传统绝对主义者”,谁拒绝一般相对主义,但采用传统的多元逻辑(第11.5-11.6节)。Florio和Linnebo认为,这种观点,在其“最合理的发展”(261)上,最终采用了一种类似于他们的批判性多元逻辑的多元逻辑。首先,“语义考虑”推动传统的绝对主义者上升一个由反复的“多元化”产生的层次结构(256)。她不仅应该支持复数资源(第1级复数),而且应该支持超复数资源(第2级复数),更一般地说,对于任何有限的n,都应该支持n级的复数。其次,无限多类型的复数会导致“可表达性问题”(256),除非像Florio和Linnebo建议的那样,传统的绝对主义者更进一步,“揭开类型区别的面纱”(261)。其结果是一种单一排序的语言,其“通用”变量同时量化每个个体、复数、超复数或其他任何级别的变量(261)。然后,如果她试图将万能变量“复数化”,那么结果逻辑就不能维持不受限制的复数理解。每个复数、超复数等等都位于层次结构的某个层次上,只有属于较低层次的成员,因此就万能变量而言,不存在“普遍复数”(261)。Florio和Linnebo认为,最终的结果与他们自己的观点“有很多共同之处”(261)。一个传统的专制主义者不愿意提升,或随后超越,多元化的等级制度可能很想仔细检查弗洛里奥和林内博的假设。语义方面的考虑与Florio和Linnebo的愿望有关,即给出一个“高度正确的”塔斯基式的逻辑推论(253),它不仅概括了标准模型理论提供的基于集合的解释,而且概括了对对象语言的每一种可能的解释。可表达性问题集中在无限类型语言无法表达关于整个层次结构的事实。然而,即使一个传统的绝对主义者愿意追随Florio和Linnebo的论点,我也怀疑最终的立场是否像他们所暗示的那样与他们的观点相似。一方面,这一论点没有对传统的绝对主义者认为某些事物包括一切的论点施加压力。弗洛里奥和林内波认为她应该放弃的所谓的普遍的“多元化”实际上——该怎么称呼它呢?-“超复数”,包括每个个体、复数、超复数,或任何复数层次上可用的东西。拒绝这种“超多元”与接受包含一切的普通的、第一层次的多元是完全相容的。更一般地说——暂时抛开松散的“复数”话题——对复数理解的有争议的限制只会出现在一种意想不到的解释上,这种解释赋予了“单数”和“复数”量词与普通量词相去甚远的含义。接受这些限制的传统绝对主义者可能仍然认为,复数理解不受其预期解释的限制,即单数和复数量词表达普通的单数和复数量词。当我们抛开复数层次的更高层次,专注于自然语言中可用的复数资源时,这种差异的重要性就显现出来了。 Florio和Linnebo的多元论的一个不同寻常的特点是,在自然语言的复数术语的语义中,复数似乎没有发挥重要作用。例如,考虑这样一个句子:“大多数事物都是非具体事物。”正如Florio和Linnebo指出的那样,像“most”这样的限定词的标准描述依赖于这样一个假设,即话语的潜在领域是一个集合(90)。在这些情况下,他们认为,集合或单独的总和在复数术语的语义分析中可以起到和复数一样的作用,甚至可能比复数更好(85 - 88,295)。我们应该如何理解这些基于集合的语义理论呢?广义相对论主义者可以接受这种理论的表面价值。在这种观点下,自然语言中任何可用的话语域都可以被编码为合适的元语言的集合。但是正如Florio和Linnebo所承认的那样,当一个人拒绝广义相对主义的时候,当她把话语的宇宙绝对包含一切的时候,她就没有同样的选择了(295)。传统的绝对主义者有一个退路。在基于集合的语义值不再可用的情况下,传统的绝对主义者可能希望利用多元资源来挽救基于集合的语义理论的语言核心。例如,包含每个个体的宇宙可以使用相应的多个来编码。但是这个选项对于批判多元逻辑的倡导者来说是不可用的。让我以一个在我看来对Florio和Linnebo来说很重要的未来任务来结束这个问题:如果自然语言复数词的语义不能总是以标准的方式被理解,不管是单个的总和,集合还是复数,那该如何理解它呢?

Existence and Modality in Kant: Lessons from Barcan 康德的存在与情态:来自巴肯的启示

This essay considers Kant’s theory of modality in light of a debate in contemporary modal metaphysics and modal logic concerning the Barcan formulas. The comparison provides a new and fruitful perspective on Kant’s complex and sometimes confusing claims about possibility and necessity. Two central Kantian principles provide the starting point for the comparison: that the possible must be grounded in the actual and that existence is not a real predicate. Both are shown to be intimately connected to the Barcan formulas, and Kant’s views on what he distinguishes as three different kinds of modality are then considered in light of this connection.
本文从当代模态形而上学和模态逻辑中关于巴肯公式的争论出发,考察康德的模态理论。这种比较为康德关于可能性和必然性的复杂、有时令人困惑的主张提供了一个新的、富有成效的视角。康德的两个主要原则为这种比较提供了出发点:一是可能性必须以现实为根据,二是存在不是实在的谓词。两者都被证明与巴肯公式密切相关,康德的观点,他区分为三种不同的情态,然后根据这种联系来考虑。
