 Modeling determinates as subspaces of a determinable space accommodates many features of determination, including, to start, Increased specificity, Determination in-respect-of determinables, Asymmetry, Irreflexivity, and Transitivity. Determinate incompatibility follows from subspaces’ being disjoint; Determinate similarity/comparability may be elucidated by reference to metrics on the spaces, whereby subspaces of a determinable space may be nearer or further apart. Funkhouser also aims to accommodate Causal compatibility by taking determinable and determinate instances (tropes) to be identical.
