 There is a different version of dispositionalism about cp-laws according to which they are not turned into strict laws (see Bird 2007: section 3.3). In a nutshell, Bird’s general idea is that the “laws are those regularities whose truth is guaranteed by the essentially dispositional nature of one or more of the constituent properties” (Bird 2007: 46–47). According to Bird, fundamental essentially dispositional properties or potencies give rise to strict laws, since there are no (or only very few) finks or antidotes that would prevent the manifestation of the potency from occurring if the stimulus had occurred (see Bird 2007 chapters 3.3.2 and 3.3.3, and the SEP-entry on dispositions for details on interferes such finks and antidotes). However, the manifestation process of non-fundamental dispositional properties can be interfered with and so the manifestation only occurs ceteris paribus, i.e., in conditions where the trigger occurs and finks and antidotes are absent (see Bird 2007: chapter 3.3.1). Therefore, these non-fundamental properties give rise to ceteris paribus laws only.
