Two Concepts of Intrinsic Value

Recent literature on intrinsic value contains a number of disputes about the nature of the concept. On the one hand, there are those who think states of affairs, such as states of pleasure or desire satisfaction, are the bearers of intrinsic value (“Mooreans”); on the other hand, there are those who think concrete objects, like people, are intrinsically valuable (“Kantians”). The contention of this paper is that there is not a single concept of intrinsic value about which Mooreans and Kantians have disagreed, but rather two distinct concepts. I state a number of principles about intrinsic value that have typically (though not universally) been held by Mooreans, all of which are typically denied by Kantians. I show that there are distinct theoretical roles for a concept of intrinsic value to play in a moral framework. When we notice these distinct theoretical roles, we should realize that there is room for two distinct concepts of intrinsic value within a single moral framework: one that accords with some or all of the Moorean principles, and one that does not.     

伦理豁免刍议

伦理豁免,是在一定的伦理尤其是亲属关系(一定程度上包括朋友关系)中,在究竟是履行伦理的义务、还是履行法律的义务之间,人们陷入紧张冲突甚至两难的情况下,被法律赋予一定的特殊权利,得依法免除法定的义务、责任甚至罪责。中华伦理、中华法系以伦理豁免来解决伦理、法律的矛盾,有宝贵的理论和实践;其中蕴涵的基本价值是,通过维护伦理,从根本上维护社会秩序。伦理豁免对今天解决伦理、法律之两难,仍是宝贵的智慧。     

Resistance to change produced by access to fixed-delay versus variable-delay terminal links

Pigeons' responding was reinforced on a multiple schedule consisting of two two-link chain schedules presented in regular alternation. Responding in initial links (always variable-interval 60-s) produced a key-color change and access to a terminal link. The terminal link for one chain provided food after a fixed delay (fixed-interval or fixed-time); the terminal link for the other provided food after a variable delay (variable-interval or variable-time). The average duration of the terminal-link schedules was varied across conditions, but in every condition the arithmetic mean of the variable-delay terminal-link schedule was equal to the duration of the fixed delay. Response rates were higher in the initial links of the chains with the variable-delay terminal links. Response-decreasing operations (satiation, extinction) were used after performances reached asymptote. Response rates maintained by access to variable-delay terminal links tended to be more resistant to change than were rates maintained by access to fixed-delay terminal links. These results are consistent with the preference for variable- over fixed-interval terminal links observed with concurrent-chains schedules, suggesting (1) that immediacy of reinforcement influences the conditioned reinforcing potency of access to a terminal link and (2) that choice in concurrent chains and resistance of responding to change may be manifestations of the same effect of reinforcement.     

Devaluation of stimuli contingent on choice: evidence for conditioned reinforcement

Pigeons were presented a concurrent-chains schedule of reinforcement that had terminal links of equal duration. The initial links of the schedule were periodically interrupted by 15-s periods during which an extinction schedule was in effect. The extinction periods were presented on either a response-contingent or a noncontingent basis. Relative response rate for the left alternative decreased when the extinction periods were accompanied by the left terminal-link stimulus. Relative response rate for the right alternative decreased when the extinction periods were accompanied by the right terminal-link stimulus. Relative response rate varied inversely with the frequency of presentation of the extinction periods but was unaffected by presence versus absence of the response contingency in the schedule of extinction-period presentation. Furthermore, relative response rate was unaffected by presentation of extinction periods accompanied by a novel stimulus. When the extinction periods were presented after reinforcement in the left terminal link instead of as interruptions of the initial links, relative response rate for the left alternative was reduced if the postreinforcement extinction period was accompanied by the terminal-link stimulus for the left chain and reduced less if the extinction period was accompanied by the terminal-link stimulus for the right chain. The results demonstrate that the correlation between the terminal-link stimulus and extinction influenced the relative response rate in the initial link.     

An analytic comparison of Herrnstein's equations and a multivariate rate equation

Herrnstein's equations are approximations of the multivariate rate equation at ordinary rates of reinforcement and responding. The rate equation is the result of a linear system analysis of variable-interval performance. Rate equation matching is more comprehensive than ordinary matching because it predicts and specifies the nature of concurrent bias, and predicts a tendency toward undermatching, which is sometimes observed in concurrent situations. The rate equation contradicts one feature of Herrnstein's hyperbola, viz., the theoretically required constancy of k. According to the rate equation, Herrnstein's k should vary directly with parameters of reinforcement such as amount or immediacy. Because of this prediction, the rate equation asserts that the conceptual framework of matching does not apply to single alternative responding. The issue of the constancy of k provides empirical grounds for distinguishing between Herrnstein's account and a linear system analysis of single alternative variable-interval responding.     

Is it always fallacious to derive values from facts?

Since the time of David Hume, many philosophers have held that there is a logical Is/Ought gap. According to the doctrine of the Is/Ought gap, there are no valid (i.e., non-fallacious) arguments from purely factual premises about whatis the case to moral or normative conclusions about whatought to be. Occasionally, this doctrine has been challenged, but frequently it has been accepted without argumentation. Charles Pigden has recently argued for a logical Is/Ought gap on the grounds of the conservativeness of logic. I offer a counter-example which shows that Pigden's argument is unsound and that there need be no logical gap between Is-premises and an Ought-conclusion. My counter-example is an argument which is logically valid, has only Is-premises and an Ought-conclusion, and does not purport to violate the conservativeness of logic. Moreover, my argument does not rely, as other alleged counter-examples do, on controversial assumptions from Aristotelian biology about natures or ends, or about institutions such as promise-making.     

Are preference reversals reduced when made explicit?

Previous research has shown that preferences for options, such as gambles, can reverse depending on the response mode. These preference reversals have been demonstrated when tasks were performed sequentially. That is, subjects completed one task before beginning another. In an attempt to eliminate preference reversals, we asked subjects to perform tasks simultaneously. That is, subjects made two types of responses for each pair of gambles before evaluating the next pair. In the condition with no financial incentives, preference reversal rates were slightly reduced. In another condition, subjects were paid for their participation and they were allowed to play a gamble with real monetary compensation. A gamble pair was randomly selected, and if a subject's responses in the two tasks were consistent for that pair, he or she was allowed to play the ‘preferred’ gamble. Otherwise, the experimenter selected the gamble from the pair. With these financial incentives, systematic preference reversals were eliminated for two of the three task combinations. Preference reversals continued to occur for attractiveness ratings versus selling prices, although, even for that pair of tasks, the reversal rate was significantly reduced. For all three task pairs, preference orders from the two tasks appeared to merge into more consistent orders.     

Organic Unities

I defend the view that there are organic unities mainly by presenting examples of organic unities. I also defend the view against two objections. The first objection appeals to the notion of an evaluatively incomplete state of affairs. The second objection holds that the intrinsic value of a state of affairs can be different in different contexts. I argue that neither objection provides a compelling reason for rejecting these examples.

The Perceptual Pathway: Tracing the Mechanisms of Political Value Transfer across Generations

The transfer of political values across generations is commonly understood as a two-step process. First, the child perceives the characteristics of the parent, thereby creating an image of what the parent is like. Second, the child is persuaded to adapt his or her own views to that image. Despite its theoretical dominance, the details of this perceptual pathway of parentalsocialization have rarely been examined empirically. A major Swedish socialization study offers unusually good opportunities to investigate how it actually operates. The results indicate that the perceptual pathway as a whole is of great but not universal significance, that perception is more important than persuasion because of its greater variability, and that the conditions regulating the former are distinct from those regulating the latter. One implication of the results is that studies of interpersonal influence based on a single source (e.g., the child alone) are likely to yield a very lopsided view of the socialization process.
