FOUNDATIONALLY JUSTIFIED PERCEPTUAL BELIEFS AND THE PROBLEM OF THE SPECKLED HEN

Many epistemologists accept some version of the following foundationalist epistemic principle: if one has an experience as if p then one has prima facie justification that p. I argue that this principle faces a challenge that it inherits from classical foundationalism: the problem of the speckled hen. The crux of the problem is that some properties are presented in experience at a level of determinacy that outstrips our recognitional capacities. I argue for an amendment to the principle that adds to its antecedent the requirement that the subject have a recognitional capacity with respect to the given property.     

A PARADOX OF JUSTIFIED BELIEVING

The following principles may plausibly be included in a wide range of theories of epistemic justification:

• (1) 

  There are circumstances in which an agent is justified in believing a falsehood,
• (2) 

  There are circumstances in which an agent is justified in believing a principle of epistemic justification,
• (3) 

  Beliefs acquired in compliance with a justifiably-believed epistemic principle are justified.

I argue that it follows from these three individually plausible claims that an agent's belief may be both justified and unjustified. I consider how theories may avoid this paradox, and conclude that deontological theories of epistemic justification face considerable, perhaps insurmountable, difficulties.     

WITHOUT CONSENT: PRINCIPLES OF JUSTIFIED ACQUISITION AND DUTY-IMPOSING POWERS

A controversy in political philosophy and applied ethics concerns the validity of duty-imposing powers, that is, rights entitling one person to impose new duties on others without their consent. Many philosophers have criticized as unplausible any such moral right, in particular that of appropriating private property unilaterally. Some, finding duty-imposing powers weird, unfamiliar or baseless, have argued that principles of justified acquisition should be rejected; others have required them to satisfy exacting criteria. I investigate the many ways in which we regularly impose duties on one another without prior consent. I show that doing so is not weird, and I offer criteria which demarcate the reasonable from the worrisome aspects of duty-imposing powers.     

人类意識的起源和发展

人类意識的起源和发展問題在現代科学中占有重要的地位,哲学的基本問題是意識对存在的关系問題,它如何解决,是唯物主义和唯心主义的根本分界綫。唯物主义者认为物貭是第一性的;意識是第二性的,是物貭长期发展的結果,是派生的。因此,研究人类意識的起源和发展,对馬克思主义哲学是有着重大意义的。 人类意識的起源和发展問題,是心理学的基本理論,它涉及到广泛的科学领域,只有在馬克思主义指导下,心理学联合人类学、考古学、語言学、历史学以及其它許多学科,进行綜合性的研究才能得到解决。现代科学对于这个問題已经积累了相当重要的資料和科学論据。     

CREATORS AND CREATURES: THE CREATION ACCOUNT IN GENESIS AND THE IDEA OF THE ARTIFICIAL HUMANOID

Science fiction, this article argues, provides an imaginative domain which can offer a unique understanding of the interaction between science and religion. Such an interaction is particularly present in the idea of the artificial humanoid as brought to life in Mary Shelley's Frankenstein and the recent television series Westworld. Both revolve around the theme of a moral relation between scientist creator and humanoid creature in accord with a norm that first took shape in the biblical account of God's creation of the first human beings. At the same time, these works of fiction cast light on the contrast between the biblical account and the Mesopotamian myths of creation. In the manner of Frankenstein and Westworld, science fiction can integrate the perspective of science with that of the biblical tradition.     

结构方程模式的发展与应用

结构方程模式(Structural Equation Modeling, SEM)在教育、心理研究中得到非常广泛的应用,但目前还有一些理论和技术上的问题有待于澄清。尤其在国内,许多研究者对这种统计方法不十分了解,因此导致了对该程序的误用以及对结果的错误解释。为此,文章首先对SEM的设计和估计方面的一些问题加以讨论;其次指出SEM在近期的一些发展以及在某些方面的最新应用;最后文章还对SEM的局限性进行了简要评述。     

中学高年级学生作文能力结构特征的研究

对４９０名高三学生的１８个作文变量的测验资料,运用高阶因素分析法概括出中学高年级学生作文能力结构的三个群因素。第一个是作文能力的因素,它是作文认知活动的各种能力相互作用的一种协调发展程度。第二个是由词汇量、造句等能力组合成的词语能力,它是作文能力结构中的一个活跃因素。第三个是词汇量因素,它独立存在于一阶、二阶因素中,表明它是不同阶段认知活动的一个不可缺的因素。     

心理因素在高血压病的发生、发展及綜合快速治疗中的作用

一、問題的提出 根据近几年来許多国家的生命統計,人类死亡的主要原因之一是心脏血管系統的疾患。在心脏血管系統疾患中,高血压病的发病率最高。我国自1958至1959年間,有13个省市普查了739,204人,高血压病的平均发病率为5.11％。高血压病是如何发生与发展的?如何对它进行有效的治疗?心理因素在高血压病的发生、发展及治疗中究竟起有什么作用?国内外医学界虽对这些問題有过不少研究介紹,但迄今还沒有得到基本     

COHERENTISM AND JUSTIFIED INCONSISTENT BELIEFS: A SOLUTION

The most pressing difficulty coherentism faces is, I believe, the problem of justified inconsistent beliefs. In a nutshell, there are cases in which our beliefs appear to be both fully rational and justified, and yet the contents of the beliefs are inconsistent, often knowingly so. This fact contradicts the seemingly obvious idea that a minimal requirement for coherence is logical consistency. Here, I present a solution to one version of this problem.
