Berkeley and the Primary Qualities: Idealization vs. Abstraction

In the First of the Three Dialogues, Berkeley’s Hylas, responding to Philonous’s question whether extension and motion are separable from secondary qualities, says:

What! Is it not an easy matter, to consider extension and motion by themselves, . . . Pray how do the mathematicians treat of them?

After some introductory comments I propose to contrast Philonous’s (Berkeley’s) answer to this question, with an alternative, arguing for the following. (1) A distinction, Berkeley would accept should be made between abstraction as Berkeley conceives it in The Introduction to the Principles of Human Knowledge and idealization, exemplified by Galileo’s ignoring friction in formulating the law of free-fall. (2) Idealizations, being neither sensible objects nor Platonic forms, illustrate the way mathematically inclined natural philosophers of the time would treat some sensible objects. (3) Therefore one puzzle Berkeley raises, whether extension can exist without color or tactile qualities, disappears. (4) So too can the resemblance puzzle be easily avoided, that is how ideas (taken here to be sensible objects) can resemble what’s in principle insensible. Lastly I suggest this way of developing Hylas’s above remark is consistent with, though not requiring, Berkeley’s idealist metaphysics.     

Body-Focused Repetitive Behaviors: The Proximal and Distal Effects of Affective Variables on Behavioral Expression

This paper reports on 2 studies designed to examine the contribution of affective variables on the expression of body-focused repetitive behaviors (BFRBs; e.g., skin picking, nail biting). The first study revealed that persons engaging in a BFRB experienced significantly higher levels of anxiety and depression than those without BFRBs. The second study was conducted to determine if repetitive behaviors were differentially affected across various emotional states and across those persons with and without BFRBs. Participants were randomly exposed to anxiety, depression, boredom, and control conditions. Results showed no differential effects on the occurrence of repetitive behaviors within the no-BFRB group; however, the BFRB group engaged in more repetitive behaviors in the Bored condition than in the Control condition. This study offers the first experimental evidence that emotional variables can have a differential impact on the expression of BFRBs.     

Paternal Psychiatric Symptoms and Maladaptive Paternal Behavior in the Home During the Child Rearing Years

Data from the Children in the Community Study, a community-based longitudinal study were used to investigate associations between paternal psychiatric disorders and child-rearing behaviors. Paternal psychiatric symptoms and behavior in the home were assessed among 782 families during the childhood and adolescence of the offspring. Paternal anxiety, disruptive, mood, personality, and substance use disorders were independently associated with specific types of maladaptive paternal behavior in the home during the child-rearing years after paternal age, education, income, co-occurring paternal psychiatric symptoms, offspring age, sex, intelligence, temperament, and psychiatric symptoms were controlled statistically. Paternal psychiatric disorders that were present by mean offspring age 14 were associated with elevated risk for maladaptive paternal behavior in the home at mean age offspring 16, after prior maladaptive paternal behavior was controlled statistically. These findings suggest that paternal psychiatric disorder may be an important determinant of maladaptive paternal behavior in the home during the child-rearing years. Improved recognition and treatment of paternal psychiatric disorders may help to reduce the amount of maladaptive parenting behavior that many children and adolescents might otherwise be likely to experience.
