Phenomenology aims to validate objects, on the basis of intentional intuitive experience [Husserl, by Bernet]
Phenomenology needs absolute reflection, without presuppositions [Husserl]

Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard]

Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard]
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic

Pure mathematics is the relations between all possible objects, and is thus formal ontology [Husserl, by Velarde-Mayol]
