We say there is no fundamental level to ontology, and reality is just patterns [Ladyman/Ross]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete
If concrete is spatio-temporal and causal, and abstract isn't, the distinction doesn't suit physics [Ladyman/Ross]
Concrete and abstract are too crude for modern physics [Ladyman/Ross]
7. Existence / D. Theories of Reality / 6. Physicalism
Physicalism is 'part-whole' (all parts are physical), or 'supervenience/levels' (dependence on physical) [Ladyman/Ross]
8. Modes of Existence / A. Relations / 1. Nature of Relations
Relations without relata must be treated as universals, with their own formal properties [Ladyman/Ross]
A belief in relations must be a belief in things that are related [Ladyman/Ross]
8. Modes of Existence / A. Relations / 2. Internal Relations
The normal assumption is that relations depend on properties of the relata [Ladyman/Ross]
8. Modes of Existence / A. Relations / 3. Structural Relations
That there are existent structures not made of entities is no stranger than the theory of universals [Ladyman/Ross]

Causal essentialism says properties are nothing but causal relations [Ladyman/Ross]

Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross]

Evidentialism says justifications supervene on the available evidence [Conee/Feldman]
14. Science / A. Basis of Science / 4. Prediction
The theory of evolution was accepted because it explained, not because of its predictions [Ladyman/Ross]
What matters is whether a theory can predict - not whether it actually does so [Ladyman/Ross]
14. Science / B. Scientific Theories / 8. Ramsey Sentences
The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross]
The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross]
14. Science / C. Induction / 1. Induction
Induction is reasoning from the observed to the unobserved [Ladyman/Ross]

Explanation by kinds and by clusters of properties just express the stability of reality [Ladyman/Ross]
