In his book Religion Is Not About God, Loyal Rue presents an evolutionarily based explanation of religion as a means to further the personal and social fulfillment of human beings. Rue argues that religions in the form of myths, adaptive falsities, provide an account of the connection between what is (facts) and what matters (values). Myths are false because they attribute subjectively based values to valueless facts, but adaptive because they motivate personally and socially beneficial actions. He maintains that the current crises of humankind, evidenced by both social conflict and environmental degradation, indicate that the major religious traditions—all of which project values onto some transcendent reality—are failing to serve humanity. To overcome these crises, Rue maintains that we need a new, scientifically based naturalized religion, one that attributes subjectively based values to Nature instead of a transcendent reality. I accept Rue's naturalism about values but reject his subjectivist account of them. Contrary to Rue, I show that the naturalistic fallacy sets no barrier to the existence of objective moral values. Modeling my view on the selection theories used in biology and psychology, I offer a scientifically based explanation of the origin and existence of objective values and support it with empirical findings from developmental psychology. Whether this account can count as religious, I do not address. 相似文献

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. 相似文献

The conjunction fallacy occurs when people judge a conjunction B‐and‐A as more probable than a constituent B, contrary to probability theory's ‘conjunction rule’ that a conjunction cannot be more probable than either constituent. Many studies have demonstrated this fallacy in people's reasoning about various experimental materials. Gigerenzer objects that from a ‘frequentist’ standpoint probability theory is not valid for these materials, and so failure to follow the conjunction rule is not a fallacy. This paper describes three experiments showing that the conjunction fallacy occurs as consistently for conjunctions where frequentist probability theory is valid (conjunctions of everyday weather events) as for other conjunctions. These experiments also demonstrate a reliable correlation between the occurrence of the conjunction fallacy and the disjunction fallacy (which arises when a disjunction B‐or‐A is judged less probable than a constituent B). This supports a probability theory + random variation account of probabilistic reasoning. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Why are people's judgments incoherent under probability formats? Research in an associative learning paradigm suggests that after structured learning participants give judgments based on predictiveness rather than normative probability. This is because people's learning mechanisms attune to statistical contingencies in the environment, and they use these learned associations as a basis for subsequent probability judgments. We introduced a hierarchical structure into a simulated medical diagnosis task, setting up a conflict between predictiveness and coherence. Thus, a target symptom was more predictive of a subordinate disease than of its superordinate category, even though the latter included the former. Under a probability format participants tended to violate coherence and make ratings in line with predictiveness; under a frequency format they were more normative. These results are difficult to explain within a unitary model of inference, whether associative or frequency-based. In the light of this, and other findings in the judgment and learning literature, a dual-component model is proposed. 相似文献

Reasoning about complex probabilistic concepts in childhood 总被引:2,自引:0,他引:2
The competencies of children, particularly their understanding of the more complex probabilistic concepts, have not been thoroughly investigated. In the present study participants were required to choose the more likely of two events, a single event, and a joint event (conjunctive or disjunctive). It was predicted that the operation of the representativeness heuristic would result in erroneous judgements when children compared an unlikely component event with a likely-unlikely conjunction (the conjunction fallacy) and when a likely component event was compared to a likely-unlikely disjunction. The results supported the first prediction with both older children aged between 9 and 10 years and younger children aged between 4 and 5 committing the conjunction fallacy. However, the second prediction was not confirmed. It is proposed that the basis of representativeness judgements may differ between the conjunctive and disjunctive cases with absolute frequency information possibly playing a differential role. 相似文献

In this paper, the traditional view that argumentum ad ignorantiam is a logical fallacy is challenged, and lessons are drawn on how to model inferences drawn from knowledge in combination with ones drawn from lack of knowledge. Five defeasible rules for evaluating knowledge-based arguments that apply to inferences drawn under conditions of lack of knowledge are formulated. They are the veridicality rule, the consistency of knowledge rule, the closure of knowledge rule, the rule of refutation and the rule for argument from ignorance. The basic thesis of the paper is that knowledge-based arguments, including the argument from ignorance, need to be evaluated by criteria for epistemic closure and other evidential rules that are pragmatic in nature, that need to be formulated and applied differently at different stages of an investigation or discussion. The paper helps us to understand practical criteria that should be used to evaluate all arguments based on knowledge and/or ignorance.

The sunk cost effect is the increased tendency to persist in an endeavor once an investment of money, effort, or time has been made. To date, humans are the only animal in which this effect has been observed unambiguously. We developed a behavior-analytic model of the sunk cost effect to explore the potential for this behavior in pigeons as well as in humans. Each trial started out with a short expected ratio, but on some trials assumed a longer expected ratio part way through the trial. Subjects had the (usually preferable) option of "escaping" the trial if the longer expected ratio had come into effect in order to bring on a new trial that again had a short expected ratio. In Experiments 1 through 3, we manipulated two independent variables that we hypothesized would affect the pigeons' ability to discriminate the increase in the expected ratio within a trial: (a) the presence or absence of stimuli that signal an increase in the expected ratio, and (b) the severity of the increase in the expected ratio. We found that the pigeons were most likely to persist nonoptimally through the longer expected ratios when stimulus changes were absent and when the increase in the expected ratio was less severe. Experiment 4 employed a similar procedure with human subjects that manipulated only the severity of the increase in the expected ratio and found a result similar to that of the pigeon experiment. In Experiment 5, we tested the hypothesis that a particular history of reinforcement would induce pigeons to persist through the longer expected ratios; the results suggested instead that the history of reinforcement caused the pigeons to persist less compared to pigeons that did not have that history. 相似文献

The new science of Complexity explains that limited knowledge prevents societies from predicting and controlling their developments. But Complexity further suggests that nature uses the limits of knowledge to evolve, which turns an apparent obstacle into an opportunity to reevaluate governmental institutions. As in nature, the limits of knowledge lead social systems to evolve by individuating, liberating, and empowering their members. Societies individuate and liberate their members to probe environments and exploit opportunities. Societies empower individuals to globalize their findings which requires constitutionally constraining governmental powers. Societies that respect human rights thus gain selective advantage. Showing that what nature is models what societies ought to be, Complexity may finesse the “naturalistic fallacy” of Hume and Moore. 相似文献

The proverbial “war between science and religion” has in many quarters reached the status of truism. Francisco J. Ayala seeks to negotiate a truce between the opposing sides through implementing the concept of the Non-overlapping Magisteria (NOMA) of science and theology. The NOMA understanding of the interaction between science and religion maintains that science and religion cannot contradict each other because each discipline has its own proper range of inquiry, namely questions of fact versus questions of value. This article explores the boundaries of these two different domains of knowledge and finds that in both theory and practice, the territorial claims overlap significantly. Furthermore, the author argues that such “territorial trespassing” is not owing to misunderstandings concerning the essence of science and of religion as such. Instead, the overlap of boundary lines—when viewed in light of the history and philosophy of science—is understood as integral to how progressive research normally advances in both science and theology. 相似文献
