Ambiguity and Undecidability in Fides et Ratio

The article offers a response to the encyclical Fides et Ratio , identifying its ambiguity with respect to two issues: the nature of the relation between faith and reason, and the diagnosis of the relation of modernity and postmodernity. The tension between the different accounts in the encyclical is not a flaw but a positive feature of the encyclical as an exercise in catholicity.     

The Methodological Impact of Fides et Ratio on Catholic Social Teaching

John Paul II’s encyclical Fides et Ratio is of astonishing importance for the methodology of Catholic social teaching. This article highlights three points that emerged as contributions of Fides et Ratio to the epistemology and methodology of the social magisterium. According to Gaudium et Spes, Catholic social teaching is essentially a service of the Church that affects social life indirectly by making a free offer of sense and faith. Fides et Ratio reinforces this paradigm shift by rejecting fideism also in matters of social morality. In this, it goes beyond Vatican I, Dei Filius. The encyclical further clarifies that the method of Catholic social teaching is tripartite and requires the cooperation of at least three disciplines: theology, philosophy, and social sciences. Because of the shifting character of history, Catholic social teaching too fluctuates. It is sensitive to time and place, to history and culture.     

Fides Quaerens Intellectum: Reflections towards an Explorative Theology1

Abstract: The postmodern critique has rendered traditional justifications of the practice of research incredible. Further, the status of theological research, in which ‘the discovery of new facts’ or the like is at best ambiguous as an aim, must be under question. This article argues that the aim of theological research is to discover what life lived as if theological claims were true might look like.     

奥古斯丁“信仰寻求理解”的哲学诠释学解读

“信仰寻求理解”源自奥古斯丁在解决三位一体的理解问题时提出的“你们要是不信,定然不得理解”。安瑟伦将其表述为“信仰寻求理解”。“信仰寻求理解”不仅指出了寻求宗教真理的途径,而且渗透着深刻的哲学诠释学思想,甚至可以说在一定意义上开始了为后世精神科学的合法性的奠基。     

On Martin Luther's Statement, “Fides Creatrix Divinitatis”

Martin Luther's statement “faith creates divinity” depends upon the antecedent promise of the crucified and triune God. When considered as a theology of gift, this statement illustrates that faith makes divinity by giving God glory.     

Ratio scales of acid sourness

Experiments were conducted to assess the relation between concentration, or pH, and the perceived sourness of 24 acids. The psychophysical functions for sourness conform to the power relation S = kCⁿ which relates sensory intensity, S, to physical concentration, C. Averaged across the 24 acids, the exponent for sourness was 0.85 for both molar and percentage concentrations, and about ?1.70 for pH concentration. The intercept, k, which is a measure of relative sourness, differed across acids. The particular measure used to designate the concentration of an acid markedly influenced its magnitude and rank order of sourness.     

Ratio scales of sugar sweetness

In a series of 10 experiments, groups of Os judged the sweetness of 16 sugars. The results suggest that, for all sugars except mannose, the intensity of sweetness grows as a power function of concentration, with an exponent of about 1.3. The relative sweetness of sugars was determined using both molarity and per cent by weight. With both measures, sucrose and fructose were the sweetest sugars. The order of the remaining sugars in the sweetness hierarchy was partiy a function of the measure of concentration. The variability of the magnitude estimates of sweetness was roughly proportional to the stimulus concentration, supporting Weber’s law.

Ratio reinforcement of matching behavior

Three pigeons, previously trained to a high level of accuracy on matching-to-sample procedures, were exposed to various schedules of ratio reinforcement for correct matches. Overall accuracy was lower on fixed ratio than on regular reinforcement. There was a high incidence of errors immediately after reinforcement on fixed ratio schedules with accuracy increasing as the ratio progressed. This increase was found to be inversely correlated with the latency of the observing response to the sample. By contrast, accuracy was high throughout the ratio on a variable ratio schedule.     

On Ratio Measures of Confirmation

There are different Bayesian measures to calculate the degree of confirmation of a hypothesis H in respect of a particular piece of evidence E. Zalabardo (Analysis 69:630–635, 2009) is a recent attempt to defend the likelihood-ratio measure (LR) against the probability-ratio measure (PR). The main disagreement between LR and PR concerns their sensitivity to prior probabilities. Zalabardo invokes intuitive plausibility as the appropriate criterion for choosing between them. Furthermore, he claims that it favours the ordering of pairs evidence/hypothesis generated by LR. We will argue, however, that the intuitive non-numerical example provided by Zalabardo does not show that prior probabilities do not affect the degree of confirmation. On account of this, we conclude that there is no compelling reason to endorse LR qua measure of degree of confirmation. On the other side, we should not forget some technicalities which still benefit PR.
