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.     

The Present Status of Group Therapy in United States Correctional Institutions

A time-limited group treatment program focusing on mothers of toddlers with a borderline personality disorder is reported. The project involved two intersecting groups—the toddler group and the mother group. The focus of the work with the children was to promote their social interests and skills to an expanded world beyond the maternal dyad. The focus of the work with the mothers was on their difficulties with emotional separation-individuation and on strengthening their ego functioning, particularly in the area of mothering so that they could participate positively in their child's separation-individuation phase.

Representative group process is presented as it organized around three distinct phases. The initial phase was marked by intense resistance, and ambivalence. During the middle phase, group cohesion developed around shared feelings and issues. The termination phase focused insistently on issues of separation. Conclusions drawn from the project include the utility of a group approach in influencing maternal behavior.     

Understanding suicidal behaviour in young people referred to specialist CAMHS: a qualitative psychoanalytic clinical research project

A qualitative psychoanalytic clinical research project using a post-Kleinian contemporary approach was undertaken by a team of seven qualified and experienced child psychotherapists working in community Tier 3 Child and Adolescent Mental Health Services (CAMHS). A number of referred young people who deliberately harmed themselves or attempted suicide, who fulfilled the inclusion criteria and consented to participate, were offered an extended individual and family assessment. Grounded Theory analysis of the qualitative data led to the formulation of the Truth Danger Theory. Typical situations in which suicidal behaviour occurred were identified, including intergenerational confusion, neglect, physical and/or sexual abuse within the family, Oedipal conflict, maternal depression and families in which there was a chronically ill sibling. We found that there was a marked disparity between the young person's experience of relationships in the family and the family's own account of their situation, a fractured reality. This can be reflected in an incongruence in the young person's presentation, which may be misleading when assessing risk. The young person feels him/herself to be in a dead end from which there seems to be no escape. Self-harm, for some, contains this impossible dilemma (albeit pathologically) but when it does not, suicide may seem the only option. The Truth Danger Theory provides explanations and predictions for suicidal behaviour and has implications for clinical practice.     

How Nice of Us and How Dumb of Me: The Effect of Exposure to Benevolent Sexism on Women’s Task and Relational Self-Descriptions

This research demonstrates how women assimilate to benevolent sexism by emphasizing their relational qualities and de-emphasizing their task-related characteristics when exposed to benevolent sexism. Studies 1 (N?=?62) and 2 (N?=?100) show, with slightly different paradigms and measures, that compared to exposure to hostile sexism, exposure to benevolent sexism increases the extent to which female Dutch college students define themselves in relational terms and decreases the extent to which they emphasize their task-related characteristics. Study 3 (N?=?79) demonstrates that benevolent sexism has more pernicious effects when it is expressed by someone with whom women expect to collaborate than when no collaboration is expected with the source of sexism. The implications of these results are discussed.     

Unsubstantiated beliefs and values flaw the Five-Factor Model of Personality

The Five-Factor Model of Personality was empirically derived and is now ubiquitous in research and applied personality psychology. However it is presented in current textbooks as including an un-evidenced component: the judgement that, while the five traits are socially desirable qualities (except socially undesirable Neuroticism), low scorers are characterised by their deficiency in essential social skills, displaying unattractive undesirable personalities. This judgement is verbally reinforced by the value-laden designations of the five traits (excepting Extraversion). Thus the model ignores evidence for cognate but contrasting personality factors that are also desirable in individuals and for society. It is proposed that traits are better understood as coming in pairs, thus resembling allelic variant expressions of genes. Extraversion and Introversion would then each reference a quality with both positive and negative potential. The traits Openness, Agreeableness and Conscientiousness could become respectively Imaginative/Practical, Empathic/Rational and Purposeful/Relaxed. It is argued that the proposed revision would yield a model more consistent with experienced, and hopefully ontological, reality than the current formulation.     

Inverse Images of Box Formulas in Modal Logic

We investigate, for several modal logics but concentrating on KT, KD45, S4 and S5, the set of formulas B for which ${\square B}$ is provably equivalent to ${\square A}$ for a selected formula A (such as p, a sentence letter). In the exceptional case in which a modal logic is closed under the (‘cancellation’) rule taking us from ${\square C \leftrightarrow \square D}$ to ${C \leftrightarrow D}$ , there is only one formula B, to within equivalence, in this inverse image, as we shall call it, of ${\square A}$ (relative to the logic concerned); for logics for which the intended reading of “ ${\square}$ ” is epistemic or doxastic, failure to be closed under this rule indicates that from the proposition expressed by a knowledge- or belief-attribution, the propositional object of the attitude in question cannot be recovered: arguably, a somewhat disconcerting situation. More generally, the inverse image of ${\square A}$ may comprise a range of non-equivalent formulas, all those provably implied by one fixed formula and provably implying another—though we shall see that for several choices of logic and of the formula A, there is not even such an ‘interval characterization’ of the inverse image (of ${\square A}$ ) to be found.     

Physical activity in infants with Down syndrome receiving a treadmill intervention

Despite the recognized relevance of physical activity in the development and health of children, assessment of physical activity levels (PA-level) in infancy is limited, especially in infants with Down syndrome (DS). Increasing PA-level using a treadmill training (TMT) intervention may benefit infants with motor delays. The purpose of this study was to investigate whether a higher intensity, individualized TMT protocol (HI) would elicit immediate and short-term higher PA-level in infants with DS than a lower intensity, generalized training protocol (LG).Thirty infants with DS were randomly assigned to the LG or the HI group. Training was terminated when the infants could walk three steps independently. Activity monitors were placed on infants’ trunks and legs for a 24-h period every other month during the intervention phase, and at set intervals 1-year post-independent walking onset. Data were analyzed to separate sedentary-to-light activity (Lowact) and moderate-to-vigorous activity (Highact).Overall our results demonstrate that infants receiving the HI TMT had higher levels of Highact than infants in the LG group, factoring out the activity produced by the intervention itself. Infants in the LG group spent more time in Lowact than the HI group. In addition, these results seemed to be retained during the post-intervention follow-up. Despite these exciting results, more work is needed to understand the relationship of the intensity of TMT on PA-level in infants with DS, and whether PA-level and TMT are related to motor milestone achievement and/or health benefits.
