Consider the source: One step in assessing premise acceptability

Premise acceptability is conceptually connected to presumption. To say that a premise is acceptable just when there is a presumption in its favor is to give a first approximation to this connection. A number of popular principles of presumption suggest that whether there is a presumption for a premise, belief, or claim depends on the sources which vouch for it. Sources consist of internal belief-generating mechanisms and external testimony. Alvin Plantinga's notion of warrant lays down four conditions upon a source for the belief which it generates to be warranted. We argue that there is a presumption for a premise, belief, or claim if and only if there is a presumption of warrant for that premise,belief or claim. This amounts to the thesis that there is a presumption for a belief from a challenger's point of view if and only if there is a presumption from that person's point of view that her cognitive faculties which have generated the belief have been functioning properly, in an appropriate cognitive environment, in accord with a segment of her design plan aimed at the truth, and that these faculties are reliable. In light of our argument for this thesis, we may legitimately claim that one way to determine that there is a presumption for a belief is to determine that there is a presumption of warrant for that belief, and thus that in determining whether there is a presumption for a belief or premise, we may consider the source.     

Why Hope is not a Moral Virtue: Aquinas's Insight

There is a growing consensus among philosophers that hope is a moral virtue: the virtuously hopeful person experiences the right amount of hope for the right things. This moralization of hope presents us with a puzzle. The historical consensus is that hope is a passion and hope is a theological virtue, not a moral virtue. Thomas Aquinas, the philosopher who wrote most extensively on hope, offers an explanation for why hope is not a moral virtue. The aim of this paper is argue that Aquinas is right in thinking that hope is not a moral virtue. 1     

Temporal Predication with Temporal Parts and Temporal Counterparts

If ordinary objects have temporal parts, then temporal predications have the following truth conditions: necessarily, (a is F) at t iff a has a temporal part that is located at t and that is F. If ordinary objects have temporal counterparts, then, necessarily, (a is F) at t iff a has a temporal counterpart that is located at t and that is F. The temporal-parts account allows temporal predication to be closed under the parthood relation: since all that is required to be F at t is to have a temporal part, a t, that is located at t and that is F, every object that has a t as a temporal part is F at t. Similarly for the temporal-counterparts account. Both closure under parthood and closure under counterparthood are shown to have unacceptable consequences. Then strategies for avoiding closure are considered and rejected.     

ABSTRACTS OF LITERATURE

This is a working guide for a technique for the initial interview in marital therapy. There is a discussion of the seating arrangement and the opening. The therapist lays out ground rules and suggests a theoretical framework for the couple. Each partner is asked to do a self-assessment scale aimed at assessing his or her desire to stay in the marriage. This is followed by a discussion of family behavior. The session is terminated with homework for each of the partners, and a therapeutic contract is made. Nonsystematic feedback suggests the technique is useful.     

Reality and Existence in Anselm

It is a premise of a widely endorsed putative refutation of Anselm's ontological argument that 'exists' is not a predicate. This Note argues that although 'exists' has the superficial grammatical appearance of a predicate in the Proslogion , Anselm does not in fact rely on the premise that 'exists' is a logical predicate (or that existing is a property) in his putative proof. It follows that even if some argument for the conclusion that 'exists' is not a predicate is sound, that argument is not a refutation of Anselm's argument.     

Assessing change with the extended logistic model

The purpose of this article is to define a method for the assessment of change. A reinterpretation of the extended logistic model is proposed. The extended logistic model for the assessment of change (ELMAC) allows the definition of a time parameter which is supposed to identify whether change occurs during a period of time, given a specific event or phenomenon. The assessment of a trend of change through time, on the basis of the time parameter which is estimated at different successive occasions during a period of time, is also considered. In addition, a dispersion parameter is calculated which identifies whether change is consistent at each time point. The issue of independence is taken into account both in relation to the time parameter and the dispersion parameter. An application of the ELMAC in a learning process is presented. The interpretation of the model parameters and the model fit statistics is consistent with expectations.     

The Adult Self: Process and Paradox

This paper defines the adult self as an identity-in-a-mutuality-of-relating, a reality that is at once a process and a paradox. As an identity-in-a-mutuality-of-relating this self has 5 characteristics, each of which is also a process and a paradox: it is a body-self; it is rooted and disclosed in feeling; it is a felt sense of depth; it has its own clear boundaries and exists in intimacy; and it is its own responsible process of experiencing. The fullness of the adult self lies in self-actualization and self-reflection, and here this self is most a process and most a paradox.     

Fry's concept of care in nursing ethics

Sara T. Fry maintains that care is a central concept for nursing ethics. This requires, among other things, that care is a virtue rather than a mode of being. But if care is a central virtue of ethics and medical ethics then the claim that care is a central concept for nursing ethics is trivial. Otherwise, it is implausible.     

Healing the wounds and the wounds of healing: a journey of the spirit

This article is a reflective narrative about the death of a parent told from the perspective of her daughter. It is an experience-based account. This shared journey of mother and child links the familiar realm of the conscious and known self to a realm that is not known in the same way and is not merely the self. It is as if one end is in the midst of life's struggles and crises and the other in another realm; yet the whole works together as a single force. In this way the idea is introduced that the very challenges and trauma of life can be a wound that is a healing of wounds, in so far as it prompts recognition of the realm that is out of sight, though the wound certainly is real enough.     

Thompson's Margaret Thatcher illusion: when inversion fails

It is argued that the whole face is more dominant than the individual features. In the case of a jumbled face the external pattern is dominant when a face is upright, whereas the internal pattern is dominant when a face is inverted.     

Trees with structure

We investigate M-trees, that is, trees with structure possible at each node or level. M is a mathematical structure such as a set or a Cartesian product. An extension of Pólya's theorem is proved which allows the number of M-trees for a given number of nodes to be counted. The special case of componential trees is investigated. Here M is a Cartesian product of 0's and 1's. A componential analysis is a componential tree of depth 1, that is, there is no hierarchy. We prove that for any componential tree there exists a componential analysis which makes the same predictions on a triad test of judged similarity. A brief empirical example is given, in which a componential tree is applied as a model of a sernantic domain.     

The nature and scope of global ethics and the relevance of the Earth Charter

This article presents global ethics as critical reflection on the nature, justification and application of a global ethic. Much of the article focuses on the nature of a global ethic as the content of global ethics, e.g. whether it is thick or thin, is about universal values or transnational responsibilities, is a set of values justified by a particular thinker, values widely shared or values universally accepted. Global ethics itself as a process is also examined. In the last part the Earth Charter is examined as an example of a global ethic, and a case is made for regarding it, both in respect to its content and in respect to the senses in which it is and is not a global ethic, as an appropriate subject matter for global ethics.     

Christian Adoption?

Abstract : Adoption is not a uniquely Christian practice, but it is a distinctly Christian act when grounded in the traditions of neighbor love and familial belonging. An orphaned child is a neighbor in need, and adoption is a fitting response to meeting this need. Caritas is the initial motive prompting this response but is not a disinterested provisional of parental care. Rather it is oriented toward parental love and familial belonging. Consequently, this Christian understanding of adoption should be preserved as a uniquely moral act in order to prevent orphaned children from being reduced to a means of remedying childlessness, or the using of adopted children as a wedge for justifying unwarranted governmental intrusion into the family.     

A digital system for recording startle,responses in small animals

An easily constructed, isometric startle-recording system is described. The animal enclosure is attached to a plywood board-which, in ten, is mounted in a “springboard” arrangement. Movement is detected by a phonocartridge mounted beneath the chamber, and a digital record of this movement is obtained through the use of a voltage-to-frequency converter. A brief experiment in which the system was used to assess the rat’s reaction to electric footshock is also presented.     

Review

I argue in this paper that anyone who accepts the ontology of scientific realism can only accept a pragmatic theory of truth, i.e., a theory on which truth is what it is epistemically right to believe. But the combination of realism with such a theory of truth is a form of internal realism; therefore, a scientific realist should be an internal realist. The strategy of the paper is to argue that there is no adequate semantic or correspondence theory of truth compatible with a realist ontology, that a redundancy theory cannot account for the value of truth, and that the only kind of truth theory which can account for the value of truth, and is compatible with a realist ontology, is a pragmatic theory. The kind of truth theory I wish to defend is objective and naturalistic, and the ontology is realistic. My position is, therefore, one of objective, naturalistic realism.     

A digital encoder for field recording of behavioral,temporal, and spatial information in directly computer-accessible form

Digitorg is an inexpensive, portable, field-operable event recorder for recording both behavioral and spatial information in real-time on audiotape. Its capacity is 256 codes. Behavioral information is recorded by pressing buttons on a keyboard and spatial information is recorded by touching a magnetic wand to a paper map overlying a matrix of switches. The audiotape recordings are played through a simple interface into a small computer, producing a permanent record of the time and identity of each event. The record is then available for analysis. Digitorg is discussed in relation to the general value of analyzing spatially differentiated behavior sequences.     

The detection of a temporal gap between two disparate stimuli

When a temporal gap is bounded by a light and a tone, gap detection performance as a function of gap duration is well described by a simple model which characterizes the discrimination as a purely temporal one. When the gap is bounded by two tones, performance is superior and seems to depend on the frequency difference between the tones, but is not well described by the same model. It is suggested that the light-tone performance represents the operation of a central temporal discrimination mechanism, while the tone-tone cases represent the use by Os of nontemporal cues originating in the peripheral auditory system.     

Cognitive processing and time perception

When a visual field is presented for 40 or 80 msec and a subject is asked to judge the duration of the stimulus, judged duration is found to be less when the field is blank than when the field contains three letters, but is the same whether the three letters form a word or not. The perceived difference between “filled” and “blank” fields increases when the subject is required to memorize the presented letters. These data are consistent with a theory which assumes,inter alia, that a stimulus is analyzed by a visual information processor and a timer, that attention is shared between these processors, and that temporal judgments are based on the output of both processors.     

The relation between the difficulty and the differential validity of a test

Using scores of 1200 students on a long test as a criterion, each of five subtests of different difficulty has maximum correlation with the criterion when the criterion is dichotomized at a value appropriate to the difficulty of the subtest. A 50-item test element is scored on an all-or-none basis with different standards for passing, and the percentage of passes for successive points on the criterion variable is computed. The Constant Method is applied to this relationship. The limen thus computed is a measure of difficulty, the dispersion is a measure of average (or total) validity, and the slope of the curve is a measure of differential validity. The difficulty of a test element is thus directly related to the maximum differential validity.
