 Most recent scholars hold that Essay 2.8.10 states what colors. etc. are according to Locke: causal capacities with intrinsic or causal ground in the PQs of insensible particles. Mark Johnston develops this in terms of a sophisticated account of a dispositional property understood as a “constituted disposition”: “a higher order property of having the properties which, oddities aside, would cause the manifestations of the disposition in circumstances C.” (Johnston 1992: 230–34) This comports with the structure of a SQ according to Essay 2.9–10, but the text says nothing about conditions or circumstances of manifestation (see discussion of Essay 2.30.2 below in this sub-section).
