Modal primitivists hold that some modal truths are primitively true. They thus seem to face a special epistemological problem: how can primitive modal truths be known? The epistemological objection has not been adequately developed in the literature. I undertake to develop the objection, and then to argue that the best formulation of the epistemological objection targets all realists about modality, rather than the primitivist alone. Furthermore, the moves available to reductionists in response to the objection are also available to primitivists. I conclude by suggesting that extant theories of the epistemology of modality are not sensitive to the question of primitivism versus reductionism.

Perceived parental acceptance and female juvenile delinquency 总被引:1,自引:0,他引:1
S E Kroupa 《Adolescence》1988,23(89):171-185
The responses of 62 adolescent females residing at a state training school and 62 high school females on a measure of perceived parental acceptance were compared while statistically controlling for mental age, chronological age, socioeconomic status, social desirability, and family structure. Generally significant (p less than .05) results indicate that incarcerated females viewed their mothers and fathers more negatively than did nonincarcerated females. Slightly more ambivalent results were indicated in the mother-daughter relationship (delinquent girls reported mothers to be more rejecting/neglecting than did nondelinquents, but no significant differences were found between the groups on perceived mother acceptance) than in the father-daughter relationship. Results were discussed in terms of reported parental differences in acceptance-nonacceptance, providing limited support for Ausubel's satellization theory of child development, and the difficulty of inferring causality from retrospective self-report studies using "captive" subjects. 相似文献
