Abstract

University of Colorado, Boulder If there are laws of psychology, they would seem to hold only ceteris paribus (c.p., hereafter), i.e., other things being equal. If a person wants that q and believes that doing a is the most efficient way to make it the case that q, then she will attempt to do a—but not, however, if she believes that a carries with it consequences much more hated than q is liked, or she believes she is incapable of doing a, or she gets distracted from her goal that q, or she suddenly has a severe brain hemorrhage, or.... No one can say precisely where the list ends, but the idea is supposed to be clear enough: normally the law holds, but there are many cases, exceptions, one might say, in which the law does not; the difficulty of characterizing these exceptions invites the qualification ‘c.p.’ as a catch-all
