8. Modes of Existence / A. Relations / 1. Nature of Relations
If relations can be reduced to, or supervene on, monadic properties of relata, they are not real [Leibniz, by Swoyer]
Relations aren't in any monad, so they are distributed, so they are not real [Leibniz]
8. Modes of Existence / C. Powers and Dispositions / 4. Powers as Essence

Leibniz was not an essentialist [Leibniz, by Wiggins]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects

Leibniz narrows down God's options to one, by non-contradiction, sufficient reason, indiscernibles, compossibility [Leibniz, by Harré]
Each monad expresses all its compatible monads; a possible world is the resulting equivalence class [Leibniz, by Rumfitt]

There is no certain supreme principle, or infallible rule of inference [Hume]
13. Knowledge Criteria / C. External Justification / 7. Testimony
We think testimony matches reality because of experience, not some a priori connection [Hume]
Good testimony needs education, integrity, motive and agreement [Hume, by PG]
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Reason can never show that experiences are connected to external objects [Hume]
Mitigated scepticism draws attention to the limitations of human reason, and encourages modesty [Hume]

Our awareness of patterns of causation is too important to be left to slow and uncertain reasoning [Hume]
16. Persons / F. Free Will / 5. Against Free Will
The doctrine of free will arises from a false sensation we have of freedom in many actions [Hume]
16. Persons / F. Free Will / 6. Determinism / a. Determinism
We think we are free because the causes of the will are unknown; determinism is a false problem [Leibniz]

Leibniz identified beauty with intellectual perfection [Leibniz, by Gardner]
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
Humans are moral, and capable of reward and punishment, because of memory and self-consciousness [Leibniz, by Jolley]

Leibniz eventually said resistance, rather than extension, was the essence of body [Leibniz, by Pasnau]
26. Natural Theory / C. Causation / 1. Causation
A priori it looks as if a cause could have absolutely any effect [Hume]
If a singular effect is studied, its cause can only be inferred from the types of events involved [Hume]
26. Natural Theory / C. Causation / 7. Eliminating causation
Hume never even suggests that there is no such thing as causation [Hume, by Strawson,G]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
At first Hume said qualities are the causal entities, but later he said events [Hume, by Davidson]
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
Hume says we can only know constant conjunctions, not that that's what causation IS [Hume, by Strawson,G]
In both of Hume's definitions, causation is extrinsic to the sequence of events [Psillos on Hume]
Hume's definition of cause as constantly joined thoughts can't cover undiscovered laws [Ayer on Hume]
A cause is either similar events following one another, or an experience always suggesting a second experience [Hume]
It is only when two species of thing are constantly conjoined that we can infer one from the other [Hume]
No causes can be known a priori, but only from experience of constant conjunctions [Hume]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Cause is where if the first object had not been, the second had not existed [Hume]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
In observing causes we can never observe any necessary connections or binding qualities [Hume]
Hume never shows how a strong habit could generate the concept of necessity [Harré/Madden on Hume]
Hume's regularity theory of causation is epistemological; he believed in some sort of natural necessity [Hume, by Strawson,G]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / c. Essence and laws
Leibniz wanted to explain motion and its laws by the nature of body [Leibniz, by Garber]
The law within something fixes its persistence, and accords with general laws of nature [Leibniz]
26. Natural Theory / D. Laws of Nature / 10. Closure of Physics
Leibniz had an unusual commitment to the causal completeness of physics [Leibniz, by Papineau]
27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces
Leibniz uses 'force' to mean both activity and potential [Leibniz]
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
God's existence is either necessary or impossible [Leibniz, by Scruton]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
It can never be a logical contradiction to assert the non-existence of something thought to exist [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
You can't infer the cause to be any greater than its effect [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / e. Miracles
A miracle violates laws which have been established by continuous unchanging experience, so should be ignored [Hume]
All experience must be against a supposed miracle, or it wouldn't be called 'a miracle' [Hume]
To establish a miracle the falseness of the evidence must be a greater miracle than the claimed miraculous event [Hume]
28. God / C. Attitudes to God / 4. God Reflects Humanity
The idea of an infinite, intelligent, wise and good God arises from augmenting the best qualities of our own minds [Hume]
28. God / C. Attitudes to God / 5. Atheism
Leibniz was closer than Spinoza to atheism [Leibniz, by Stewart,M]
