 Given the role essences play in individuation, this approach promises to characterize determinable events in properly non-reductive terms, at both the type and token levels, and might be extended to a more general non-reductive account of determinables, capable of accommodating the range of motivations for irreducible determinables. Taking determinables to have essences contained within determinate essences would also clearly explain various features of determination, including (besides Asymmetric dependence, which is presumably still in force), Determinable inheritance and Determination ‘in respect of’ determinables. More needs to be said, however if an appeal to essences is to explain certain other features of determination, including Non-conjunctive specification, Requisite determination, Determinate opponent incompatibility, and—importantly for Yablo’s intended application of determination to the problem of mental causation;  see §5.2—Causal compatibility.
