In the first part I discuss the thesis, advanced by John Broome, that intentions are normatively required by all-things-considered judgments about what one ought to do. I endorse this thesis, but remain sceptical about Broome's programme of grounding the correctness of reasoning in formal relations between contents of mental states. After discussing objections to the thesis, I concentrate in the second part on the relation between rational action and rational intention. I distinguish between content-related and attitude-related reasons for propositional attitudes like believing, wanting, and intending something. The former appeal to features of the content of the propositional attitude they are reasons for, the latter would be reasons for a propositional attitude because of features of the propositional attitude as a whole, for example the feature of its being beneficial to believe or to want that p . I try to show that the common philosophical reaction to attitude-related reasons, namely to claim that they are merely content-related reasons in disguise, is mistaken. In its most extreme form such a reaction would fail to respect the first-person character of reasoning which manifests itself in, among other things, the fact that a Moore-sentence and its analogue for intentions cannot be a conclusion of reasoning. In the third part I argue that there are attitude-related reasons for intentions, and, in showing how they influence practical deliberation, I find that their existence can be rendered compatible with the thesis that it is rational to intend to do what one thinks one ought to do.  相似文献

Adherence to medications for chronic pediatric diseases decreases overtime. This randomized controlled trial evaluated a clinic-based, nurse-administered educational and behavioral intervention to prevent the anticipated drop in adherence to nonsteroidal medications among newly diagnosed patients with juvenile rheumatoid arthritis. Thirty-four participants completed the study (mean age = 8.44 years, SD = 3.96), including 19 in the experimental group and 15 in the standard-treatment (education) control group. There were significant group and Group x Time effects for adherence (assessed with an electronic monitor over a 13-month period) favoring the experimental group. In contrast, the groups did not differ significantly in disease activity or functional limitations. Factors that may have prevented detection of differences in these health parameters are dicussed.  相似文献

A Black feminist model was used to investigate rape myth acceptance between African American antirape activists and a comparison group of nonactivists using Cross's (1991) racial identity model and Downing and Roush's (1985) feminist identity model. As predicted, activists rejected rape myths more than nonactivists; the earlier stages of both models were associated with rape myth acceptance; the later stages were associated with rape myth rejection; and activists evidenced more sociopolitical maturity (race and gender consciousness) than nonactivists. The findings suggest that researchers may need to investigate to what degree rape myth acceptance serves an overarching system of social domination where racism and sexism overlap.  相似文献
