The Fallacy Fallacy: From the Owl of Minerva to the Lark of Arete

The fallacy fallacy is either the misdiagnosis of fallacy or the supposition that the conclusion of a fallacy must be a falsehood. This paper explores the relevance of these and related errors of reasoning for the appraisal of arguments, especially within virtue theories of argumentation. In particular, the fallacy fallacy exemplifies the Owl of Minerva problem, whereby tools devised to understand a norm make possible new ways of violating the norm. Fallacies are such tools and so are vices. Hence a similar problem arises with argumentative vices. Fortunately, both instances of the problem have a common remedy.

     

A signal detection analysis of the effects of hearing on the visual recognition of two-digit numbers

A signal detection measure of visual recognition was used to assess the visual recognition of two-digit numbers in three different conditions: (1) voicing of the number as it was presented visually; (2) voicing of a different number than the one presented; and (3) no voicing. The three treatment means were significantly different, with matched voicing resulting in the best performance and no voicing, in the worst. There was no evidence that the treatments differentially affected response criteria.     

Stimulus control and the growth of the infant’s effective visual field*

The size of the infant’s effective visual field was studied weekly in infants starting at 2 weeks of age until they were 10 weeks old, The field was initially quite small, 15 deg to either side of their line of regard. Over the 2-month period of the study, it more than doubled for stimulus conditions in which the peripheral event was in motion and the fixation object static, and it remained approximately the same size when motion was present in the fixation event and the peripheral object was static. As with adults, the infant’s effective visual field is directly related to the stimuli available.     

A suit for protecting chronically implanted devices in monkeys

Humanness: A Therapeutic Variable

Since attempts by adherents to various psychotherapeutic orientations have failed to demonstrate the efficacy of any one of them, this paper tries to explicate the single variable—humanness—that seems to underlie all therapeutic approaches, and may account for the positive results obtained by all approaches. Many investigators have emphasized the importance of a positive relationship as a factor in counseling; but an influential force, behavior modification therapy, has attempted to once again place the role of technique in the spotlight. Their results have not been striking. A second aim, therefore, of this paper is to offer a critique of this position in the light of humanistic and research considerations. The implications of a technique-oriented therapeutic approach are also discussed. A plea is entered for emphasis being placed on, and an investigation of, the role of humanness as the most important variable in the counseling process.
