Instantiae: An introduction to a twelfth century technique of argumentation

An instantia is a technique to refute other's arguments, found in many tracts from the latter half of the twelfth century. An instantia has (or appears to have) the same form as the argument to be refuted and its falsity is more evident than that of the argument.Precursors of instantiae are among the teachings of masters active in the first half of the century. These masters produce counter-arguments against various inferential forms in order to examine their validity. But the aim of producing counter-arguments change in the latter half of the century into refuting other's arguments to win in debate by any means available. Logicians of that period do not care whether the counter-arguments (instantiae) are sophistical or not, viz. the falsity of instantiae is or is not due to the flaw common to the argument to be refuted.Many instantiae they produce involve logical entanglements into which they themselves have little clear insight. Some instantiae and the attempts to explain them grows into the new theories in the terminist texts around 1200 A.D., when instantia literature itself disappears. Some instantiae and the issues they raise have no place in terminist texts, and sink into oblivion.Abbreviations CIMAGL Cashiers de l'Institut du Moyen-Âge grec et latin, Copenhagen 1969. - I. Mon.

Women returning to school: The consequences of multiple roles

Previous research suggests that strain is a predominant consequence of multiple-role incumbency. The likelihood of negative outcomes is increased when the role combination is non-normative. The validity of these assertions is tested for a group of women who have returned to school at midlife, comparing them to a group of their neighbors who are primarily housewives. Findings demonstrate that the students experienced significantly greater positive outcomes or gratifications from their multiple roles than the housewives experienced from their relatively unitary roles. However, the students also reported significantly more negative consequences or strain than did the housewives. Though the students had a net positive gain, the difference was not significant. Moreover, role strain was negatively correlated with high levels of involvement in leisure and volunteer activities for both subsamples. Finally, feminist ideology varied directly with gratification for both students and housewives. The mix of positive and negative corollaries of multiple roles challenges the assumption in the literature that strain is an ubiquitous outcome. The implications of these results are discussed in terms of sexual division of labor and strategies for enhancing net gratification.I am grateful to Judith Long for her assistance in conceptualizing and designing this research. Anne Foner, Peggy A. Thoits, and anonymous reviewers for Sex Roles made numerous helpful comments which strengthened the final version. An earlier version of this paper was presented at the annual meeting of the American Sociological Association, San Antonio, Texas, August 1984.     

Effect of observing response requirements to sample and comparison stimuli on the establishment of reject control (sample/S- relations)

The establishment of sample/S- relations (or reject control) during conditional discrimination training (AB, BC) affects transitivity (AC), equivalence (CA) and reflexivity (AA, BB, CC) test outcomes. The present study parametrically evaluated the effects of different observing patterns to comparison stimuli on the establishment of reject control during baseline conditional relation training. A matching-to-sample with observing requirements (MTS-OR) procedure was implemented during AB and BC conditional discrimination training. During training, the participants were required to observe the sample and incorrect comparison on every trial before responding. In addition, the participants were divided into three groups that differed regarding the percentage of training trials on which they were prevented from observing the correct comparison stimuli: 25%, 50%, and 75%. Once the mastery criteria were achieved during training, transitivity (AC), symmetry (BA, CB), equivalence (CA), and reflexivity (AA, BB, CC) tests were conducted with all comparison stimuli visible from the beginning. The results suggest that the number of errors during transitivity, equivalence, and reflexivity tests progressively increased as participants were prevented from observing the correct comparison on a greater number of trials during training. Symmetry test results, however, were not affected by the experimental manipulation. Moreover, the number of participants showing reject-control patterns during tests slightly increased and the number of participants showing select-control patterns decreased as a function of the number of trials on which the participants were prevented from observing the correct comparison. Thus, we suggest that observing patterns during training is a relevant variable that affects equivalence test outcomes.     

Platonic Knowledge and the Standard Analysis

Abstract

In this paper I explore Plato’s reasons for his rejection of the so‐called standard analysis of knowledge as justified true belief. I argue that Plato held that knowledge is an infallible mental state in which (a) the knowable is present in the knower and (b) the knower is aware of this presence. Accordingly, knowledge (epistēmē) is non‐propositional. Since there are no infallible belief states, the standard analysis, which assumes that knowledge is a type of belief, cannot be correct. In addition, I argue that Plato held that belief (doxa) is only possible for the sort of being capable of knowledge. This is because self‐reflexivity is necessary for infallible knowledge and self‐reflexivity is only possible if the intellect is immaterial. This capacity for self‐reflexivity is also essential for belief, since beliefs are, paradigmatically, not dispositions but self‐reflexive mental states.     

Cognitive load on working memory both encourages and discourages reasoning bias regarding the mental states of others

Theory of mind (ToM) refers to the ability to reason about the mental states of others. An increasing number of studies have revealed that working memory (WM) plays an important role in ToM. The present study applied WM loads to adults during a ToM task in order to investigate the impact on mental‐state reasoning performance. The task required participants to estimate the probabilities of several possible behaviours for a protagonist following the presentation of a ToM story. Participants were also required to maintain a meaningless two‐ (light WM load) or seven‐letter English alphabet string (heavy WM load) during story comprehension and mental‐state reasoning. The results show that the combination of light WM load applied during story comprehension with heavy WM load during mental‐state reasoning results in an overestimation of the probability that the protagonist's behaviour will accord with a participant's knowledge. Conversely, a heavy WM load applied during story comprehension, regardless of the type of WM load during mental‐state reasoning, did not result in this probability estimation bias. We discuss these findings from the perspective of a WM representation account.     

Humiliation and the Cultural and Relational Structuring of Hysteria: Reply to Commentaries

In this reply to the discussions by Muriel Dimen and Richard Lasky of “Hysteria and Humiliation” I emphasize how historical theoretical conceptualizations of hysteria have always been informed by derogatory attitudes. I concur with Dimen's view that power is always invoked in gender and race relations and that these inevitably find their way into the clinical. I disagree with Lasky's view that the hysteric can be understood primarily through the operation of “autonomous mental events” and that too great a reliance on this concept obscures the role of cultural and developmental experiences of humiliation in the origins and maintenance of hysteric phenomena.     

Hysteria and Humiliation

The phenomena of hysteria are first considered from a historical perspective that emphasizes the role of domination and power relations between the sexes. This permits an examination of the dynamics and impact of humiliation in interpersonal relations on the formation of hysteric symptomatology. Humiliation is viewed as having a powerful deleterious effect on the development of the capacity to think and feel in a coherent and meaningful manner. The relationship between humiliation and hysteria is explored theoretically and illustrated with clinical material that emphasizes developmental dynamics through which relationally based injuries fracture the ability to know and communicate one's experience.     

I see into your mind too well: working memory adjusts the probability judgment of others' mental states

Although an increasing number of studies on adults have indicated that working memory (WM) contributes to the ability to understand the mental states of others (i.e., theory of mind), the detailed mechanism by which WM contributes to successful reasoning has not previously been revealed. This study shows that WM modulates the degree of attribution of one's own knowledge to others' mental states. Participants were asked to read a story twice (Experiment 2) or as carefully as possible (Experiment 3) and to estimate the probability percentages of possible choices for a naive protagonist's behavior. The participants were then asked to maintain either a two- or seven-letter alphabet string (i.e., a light or heavy WM load, respectively) during the probability estimation but not during the story comprehension. The results showed that compared to the participants with a light WM load, those with a heavy WM load estimated a significantly higher probability of the choice indicating that the protagonist would behave on the basis of a fact that the participants knew but the protagonist did not. This result indicates that WM moderates the extent to which adults attribute their own knowledge to others' mental states. The role of WM in theory of mind and in heuristic strategy for making probability judgments was then discussed.     

The World of Mad Men: Power,Surface and Passion

Mad Men is disturbing to post-millennium viewers, particularly those of a “certain” age, on three counts. First, it invokes a particular historical context of gender oppression; second it captures the prevailing post-War injunction that emotional distress is unseemly and distasteful; and third, it captures the zeitgeist's celebration of surface over substance in relationship. However, just as disturbing as these historically situated interpersonal premises is the niggling question that each relationship pairing and each episode leaves with the viewer. To wit: How much of the disconnection and the unrequited longings are reflective of a particular historical era, and to what degree do they reflect timeless aspects of character and relationship? Thus Mad Men provides an exquisitely rendered sociocultural tableau in which the viewer struggles, however articulated or not, with one of the essential knots of psychoanalytic as well as couples treatment: the complicated interpenetration of culture and character, of time and timelessness.
