The other basic aspect of reality.

Abstract

It is argued that physical (and not inherently psychical) properties are insufficient to constitute all else. Specifically they cannot constitute an instance (K1) of our knowledge that the number of existing things is at least one. This employs a new version of entry by entailment: Every fact as to the presence of a constituted trope is entailed by facts about the presence of the ontologically basic, where a property is ontologically basic if and only if the fact of its presence is not entailed (even allowing exhaustive definitions of all tropes in terms of their ultimate constituents) by facts about the presence of things non-identical to it. Existence is a mind-independent presence. Things can be present (to mind) as opposed to existing but must be accompanied by the presence of all of their parts and of anything else that their presence might entail. This includes some existing thing in the case that knowledge that something exists is present, since it is analytic that knowledge cannot be of what is not the case. Purely dynamical properties cannot exist apart from instances of some other property kind (on pain of regress as to what moves). Material properties can make a difference to cognitive states only in virtue of differences they can make to dynamical properties. Thus, any cognitive state present in some dynamical and material scenario must be present in an equivalent purely dynamical scenario, which cannot exist. Hence: 1) There can be no knowledge of existence, or thus trope K1, in a purely dynamical scenario. 2) There can thus neither be a trope K1 if only dynamical and material properties (and what they constitute) are present. So because there is a trope K1, there are one or more ontologically basic properties which are not dynamical or material. It is further argued that nothing ontologically basic is per se (directly and non-obscurely) conceivable except as psychicality or a categorical basis of a disposition to change or constancy (respectively, dynamism and materiality). Thus at least one ontologically basic property is either psychical or not per se conceivable. The latter proposition has less merit.
