1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
Reductive analysis makes a concept clearer, by giving an alternative simpler set
2. Reason / E. Argument / 1. Argument
Promoting an ontology by its implied good metaphysic is an 'argument-by-display'
7. Existence / B. Change in Existence / 1. Nature of Change
Change exists, it is causal, and it needs an explanation
7. Existence / B. Change in Existence / 2. Processes
Processes don't begin or end; they just change direction unexpectedly
Processes are either strings of short unchanging states, or continuous and unreducible events
7. Existence / D. Theories of Reality / 1. Ontologies
The status quo is part of what exists, and so needs metaphysical explanation
A metaphysic is a set of wider explanations derived from a basic ontology
Humeans say properties are passive, possibility is vast, laws are descriptions, causation is weak
We shouldn't posit the existence of anything we have a word for
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Powers are 'multi-track' if they can produce a variety of manifestations
Every possible state of affairs is written into its originating powers
Naming powers is unwise, because that it usually done by a single manifestation
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Fundamental physics describes everything in terms of powers
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Rather than pure powers or pure categoricals, I favour basics which are both at once
Powers are more complicated than properties which are always on display
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
There are basic powers, which underlie dispositions, potentialities, capacities etc
Dispositions are just useful descriptions, which are explained by underlying powers
9. Objects / A. Existence of Objects / 1. Physical Objects
If objects are property bundles, the properties need combining powers
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
Four-Dimensional is Perdurantism (temporal parts), plus Eternalism
26. Natural Theory / C. Causation / 1. Causation
Causation is the exercise of powers
Causation needs to explain stasis, as well as change
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
If causes and effects overlap, that makes changes impossible
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / c. Essence and laws
Powers contain lawlike features, pointing to possible future states
