Resolving conflicts among principles: ranking, balancing, and specifying.

While much attention has been given to the use of principles in biomedical ethics and increasing attention is given to alternative theoretical approaches, relatively little attention has been devoted to the critical task of how one resolves conflicts among competing principles. After summarizing the system of principles and some problems in conceptualizing the principles, several strategies for reconciling conflicts among principles are examined including the use of single-principle theories (pure libertarianism, pure utilitarianism, and pure Hippocratism), balancing theories, conflicting appeals theories, and lexical ordering. Then a mixed strategy is proposed in which consequentialist principles are balanced between themselves as are nonconsequentialist principles, after which the result of balancing the nonconsequentialist principles is lexically ranked over the result of balancing the consequentialist ones. Finally, strategies involving specifying and rule generation are discussed concluding that most current specification and rule-generating theories must involve some degree of lexical ordering of principles.     

Neologicist Nominalism

The goal is to sketch a nominalist approach to mathematics which just like neologicism employs abstraction principles, but unlike neologicism is not committed to the idea that mathematical objects exist and does not insist that abstraction principles establish the reference of abstract terms. It is well-known that neologicism runs into certain philosophical problems and faces the technical difficulty of finding appropriate acceptability criteria for abstraction principles. I will argue that a modal and iterative nominalist approach to abstraction principles circumvents those difficulties while still being able to put abstraction principles to a foundational use.     

Explaining enkratic asymmetries: knowledge-first style

There are two different kinds of enkratic principles for belief: evidential enkratic principles and normative enkratic principles. It’s frequently taken for granted that there’s not an important difference between them. But evidential enkratic principles are undermined by considerations that gain no traction at all against their normative counterparts. The idea that such an asymmetry exists between evidential and normative enkratic principles is surprising all on its own. It is also something that calls out for explanation. Similarly, the considerations that undermine evidential enkratic principles also undermine certain narrow-scope evidential principles. This too generates explanatory questions. I show how a knowledge-first view of rationality can easily address these (and further) explanatory questions. Thus we have one more reason to put knowledge first in epistemology.     

Applied Ethics: Naturalism, Normativity and Public Policy

abstract   Normative argument is supposed to guide ways in which we might change the world, rather than to fit the world as it is. This poses certain difficulties for the notion of applied ethics. Taken literally the phrase 'applied ethics' suggests that principles or standards with substantial philosophical justification, in particular ethical and political principles with such justification, are applied to particular cases and guide action. However, the 'cases' which applied ethics discusses are themselves indeterminate, and the relation of principles to these 'cases' differs from the relation of principles to cases in naturalistic, truth-oriented inquiry. Writing in 'applied ethics', I shall argue, does not need elaborate case histories or scenarios, since the testing points for normative principles are other normative principles rather than particular cases. Normative principles and contexts to which they are applicable are indeed needed for any reasoning that is practical, but they are not sufficient. Practical ethics needs principles that can not merely be applied in certain cases or situations, but also enacted in certain ways, and requires an account of practical judgement and of the public policies that support that judgement .     

Interactions between intrinsic principles of similarity and proximity and extrinsic principle of common region in visual perception

The interactions between intrinsic grouping principles (by proximity or by similarity in shape or luminance) and extrinsic grouping by common region were examined by presenting both principles acting alone or conjoined with another principle in visual patterns. The procedure used in our study closely mirrored that of Quinlan and Wilton (1998 Perception 27 417-430). However, in the present experiment, the intrinsic and extrinsic grouping principles involved had similar relative salience in order to avoid their possible effects on interactions. The results showed that the grouping effect of conjoined cooperating principles was greater than that of either principle acting alone, and the grouping effect of conjoined competing principles was lower than that of either principle operating alone. Compatibility of data with additive effects of grouping principles has been examined.     

Understanding and using principles of arithmetic: operations involving negative numbers

Previous work has investigated adults' knowledge of principles for arithmetic with positive numbers ( Dixon, Deets, & Bangert, 2001 ). The current study extends this past work to address adults' knowledge of principles of arithmetic with a negative number, and also investigates links between knowledge of principles and problem representation. Participants ( N = 44) completed two tasks. In the Evaluation task, participants rated how well sets of equations were solved. Some sets violated principles of arithmetic and others did not. Participants rated non-violation sets higher than violation sets for two different principles for subtraction with a negative number. In the Word Problem task, participants read word problems and set up equations that could be used to solve them. Participants who displayed greater knowledge of principles of arithmetic with a negative number were more likely to set up equations that involved negative numbers. Thus, participants' knowledge of arithmetic principles was related to their problem representations.

Development of the concept of comparative subjective probability

This study investigates which formal principles govern subjective probability, and whether the validity of these principles depends on age. Two types of tasks were administered to 144 subjects from 3;8 to 19 years: a gambling task (with objective probabilities) and a sporting task (without objective probabilities). Six formal principles of the mathematical concept of qualitative probability (a nonnumerical concept based on ordinal scale properties) were tested. Results indicate that these principles are valid as principles of subjective probability for all age groups. Only the youngest age group (4 years or younger) had a smaller degree of confirmation.     

Deference and Uniqueness

Philosophical Studies - Deference principles are principles that describe when, and to what extent, it’s rational to defer to others. Recently, some authors have used such principles to argue...     

Vagueness and Margin for Error Principles*

Timothy Williamson's potentially most important contribution to epistemicism about vagueness lies in his arguments for the basic epistemicist claim that the alleged cut‐off points of vague predicates are not knowable. His arguments for this are based on so‐called ‘margin for error principles’. This paper argues that these principles fail to provide a good argument for the basic claim. Williamson has offered at least two kinds of margin for error principles applicable to vague predicates. A certain fallacy of equivocation (on the meaning of ‘knowable’) seems to underlie his justification for both kinds of principles. Besides, the margin for error principles of the first kind can be used in the derivation of unacceptable consequences, while the margin for error principles of the second kind can be shown to be compatible with the falsity of epistemicism, under a number of assumptions acceptable to the epistemicist.     

What Principles Are Used to Judge the Fairness of Retrenchment Actions?

The present study identified the bipolar principles that workers use for evaluating the fairness of a broad range of negative organizational events. Two hundred forty-eight respondents were asked to describe recent negative events that occurred in their organizations, and explain the reasons for their fairness perceptions of the events. The responses were coded to yield 5 principles associated with outcome fairness and 8 principles associated with process fairness; this set included principles not found in earlier taxonomies. Support for previous justice models and needed areas of research are discussed.     

MENTAL ARITHMETIC IN AFRICA AND AMERICA: STRATEGIES,PRINCIPLES, AND EXPLANATIONS*

Mental arithmetic abilities were studied among unschooled African adults and American college students. A set of problems tested the use of the four basic arithmetic operations. Performance was analyzed for: strategies, implicit arithmetic principles, and explicit explanations of the principles. Both groups showed accurate mental arithmetic strategies related to the base ten structure of their native counting systems. The American students' mental strategies additionally made use of algorithms based on written place values. Several principles were implicit in the calculation strategies of both groups, and both used these principles to short-cut calculations. Though the African subjects did not, the American subjects did describe these abstract principles in explicit common language or algebraic expressions. Relationships between schooling and cognition are discussed.     

Preference relations

Various principles about preferences between sets of options are presented and considered with respect to several familiar decision rules. Necessary and sufficient (or minimally sufficient) preference principles are given for each rule. The paper concludes with an example of how easy it is to misjudge the reasonableness of preference principles.     

COHEN TO THE RESCUE!

Cohen seeks to rescue the concept of justice from those, among whom he includes Rawls, who think that correct fundamental moral principles are fact‐sensitive. Cohen argues instead that any fundamental principles of justice, and fundamental moral principles generally, are fact‐insensitive and that any fact‐sensitive principles can be traced back to fact‐insensitive ones. This paper seeks to clarify the nature of Cohen's argument, and the kind of fact‐insensitivity he has in mind. In particular, it distinguishes between internal and external fact‐sensitivity – that is, whether facts are referenced in the content of the principle, or must otherwise be the case in order for the principle to apply at all. Cohen himself seems likely to endorse internally fact‐sensitive fundamental principles. This leads to a discussion of Cohen's Platonism about moral principles and the extent to which his arguments cover all its rivals. 1     

The role of conscious reasoning and intuition in moral judgment: testing three principles of harm

Is moral judgment accomplished by intuition or conscious reasoning? An answer demands a detailed account of the moral principles in question. We investigated three principles that guide moral judgments: (a) Harm caused by action is worse than harm caused by omission, (b) harm intended as the means to a goal is worse than harm foreseen as the side effect of a goal, and (c) harm involving physical contact with the victim is worse than harm involving no physical contact. Asking whether these principles are invoked to explain moral judgments, we found that subjects generally appealed to the first and third principles in their justifications, but not to the second. This finding has significance for methods and theories of moral psychology: The moral principles used in judgment must be directly compared with those articulated in justification, and doing so shows that some moral principles are available to conscious reasoning whereas others are not.     

Some prerequisites for a political casuistry of justice

After briefly vindicating casuistries which successively apply a number of different moral principles, I describe some of the principles of justice liable to figure in such casuistries, assess the relative popularity of these principles and show that some of the most popular cannot be consistently applied in all circumstances.

Each of the six principles is formally stated and then followed by explanation and examples.     

事件类型的相似性对原理运用影响的实验研究

探讨样例与测题在表面概貌的事件类型方面发生改变的条件下,两者的表面概貌相似性对原理运用的影响。结果表明：1．样例与问题的表面概貌在事件类型方面发生变化时。其表面慨貌相似性对原理运用就会表现出明显的影响;2．样例与问题的表面概貌对原理运用的影响作用．要受到两者的对象对应的类型的影响．当对象对应相似时,其表面概貌相似就会促进解答测题时的原理运用,反之会产生干扰作用。据此可以认为。Ross关于表面概貌相似与否不影响原理运用的结论应予以改正。     

Where’s the GPS? navigating treatment with co-existing problems. A reflective journey amongst graduate practitioners

This paper examines reflective portfolios of graduate students studying co-existing problems (CEP) within an alcohol and drug studies programme in New Zealand. The methodology employs Todd’s principles of treating co-existing disorders (culture, management, engagement, assessment, integrated care, well-being and management). The metaphor, a GPS, is employed in the title to describe how Todd’s principles are used as a GPS to help navigate the murky waters of working with this specialised client population. The principles, allocated as themes within the portfolios, highlight how these principles are reflected upon within their workplace. Culture and engagement principles were the most endorsed themes within the portfolios. The reflective portfolios also allowed us to reflect upon the ongoing process of curriculum development for this specialised client population.
