A contextual definition permits the elimination of the expression by a substitution [Dummett]
5. Theory of Logic / A. Overview of Logic / 6. Classical Logic
In classical logic, logical truths are valid formulas; in higher-order logics they are purely logical [Dummett]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / b. Types of number
A prime number is one which is measured by a unit alone [Dummett]

6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / e. Structuralism critique
The identity of a number may be fixed by something outside structure - by counting [Dummett]
Numbers aren't fixed by position in a structure; it won't tell you whether to start with 0 or 1 [Dummett]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Set theory isn't part of logic, and why reduce to something more complex? [Dummett]
7. Existence / B. Change in Existence / 2. Processes
A process is unified as an expression of a collection of causal powers [Mumford/Anjum]
7. Existence / B. Change in Existence / 4. Events / a. Nature of events
Events are essentially changes; property exemplifications are just states of affairs [Mumford/Anjum]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / a. Abstract/concrete
The distinction of concrete/abstract, or actual/non-actual, is a scale, not a dichotomy [Dummett]
7. Existence / D. Theories of Reality / 2. Realism
Realism is just the application of two-valued semantics to sentences [Dummett]
8. Modes of Existence / B. Properties / 7. Emergent Properties
Weak emergence is just unexpected, and strong emergence is beyond all deduction [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Powers explain properties, causes, modality, events, and perhaps even particulars [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Powers offer no more explanation of nature than laws do [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
Powers are not just basic forces, since they combine to make new powers [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
Dispositionality is a natural selection function, picking outcomes from the range of possibilities [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
We say 'power' and 'disposition' are equivalent, but some say dispositions are manifestable [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / c. Dispositions as conditional
The simple conditional analysis of dispositions doesn't allow for possible prevention [Mumford/Anjum]
8. Modes of Existence / C. Powers and Dispositions / 7. Against Powers
Might dispositions be reduced to normativity, or to intentionality? [Mumford/Anjum]
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
Nominalism assumes unmediated mental contact with objects [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / a. Nature of abstracta
The existence of abstract objects is a pseudo-problem [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / c. Modern abstracta
Abstract objects nowadays are those which are objective but not actual [Dummett]
It is absurd to deny the Equator, on the grounds that it lacks causal powers [Dummett]
'We've crossed the Equator' has truth-conditions, so accept the Equator - and it's an object [Dummett]
9. Objects / A. Existence of Objects / 2. Abstract Objects / d. Problems with abstracta
Abstract objects need the context principle, since they can't be encountered directly [Dummett]

If statue and clay fall and crush someone, the event is not overdetermined [Mumford/Anjum]
9. Objects / C. Structure of Objects / 1. Structure of an Object
Pandispositionalists say structures are clusters of causal powers [Mumford/Anjum]
9. Objects / E. Objects over Time / 5. Temporal Parts
Perdurantism imposes no order on temporal parts, so sequences of events are contingent [Mumford/Anjum]
9. Objects / F. Identity among Objects / 2. Defining Identity
Content is replaceable if identical, so replaceability can't define identity [Dummett, by Dummett]
Frege introduced criteria for identity, but thought defining identity was circular [Dummett]
10. Modality / A. Necessity / 1. Types of Modality
Dispositionality is the core modality, with possibility and necessity as its extreme cases [Mumford/Anjum]
Dispositions may suggest modality to us - as what might not have been, and what could have been [Mumford/Anjum]
10. Modality / A. Necessity / 7. Natural Necessity
Relations are naturally necessary when they are generated by the essential mechanisms of the world [Mumford/Anjum]
10. Modality / B. Possibility / 1. Possibility
Possibility might be non-contradiction, or recombinations of the actual, or truth in possible worlds [Mumford/Anjum]
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Maybe truths are necessitated by the facts which are their truthmakers [Mumford/Anjum]
12. Knowledge Sources / B. Perception / 1. Perception
We have more than five senses; balance and proprioception, for example [Mumford/Anjum]
14. Science / A. Basis of Science / 6. Falsification
Smoking disposes towards cancer; smokers without cancer do not falsify this claim [Mumford/Anjum]
14. Science / C. Induction / 1. Induction
If causation were necessary, the past would fix the future, and induction would be simple [Mumford/Anjum]
The only full uniformities in nature occur from the essences of fundamental things [Mumford/Anjum]
14. Science / C. Induction / 3. Limits of Induction
Nature is not completely uniform, and some regular causes sometimes fail to produce their effects [Mumford/Anjum]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
It is tempting to think that only entailment provides a full explanation [Mumford/Anjum]
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
A structure won't give a causal explanation unless we know the powers of the structure [Mumford/Anjum]
17. Mind and Body / D. Property Dualism / 4. Emergentism
Strong emergence seems to imply top-down causation, originating in consciousness [Mumford/Anjum]
18. Thought / D. Concepts / 4. Structure of Concepts / i. Conceptual priority
Maybe a concept is 'prior' to another if it can be defined without the second concept [Dummett]
An argument for conceptual priority is greater simplicity in explanation [Dummett]
18. Thought / E. Abstraction / 1. Abstract Thought
Abstract terms are acceptable as long as we know how they function linguistically [Dummett]
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
There is no reason why abstraction by equivalence classes should be called 'logical' [Dummett, by Tait]
We arrive at the concept 'suicide' by comparing 'Cato killed Cato' with 'Brutus killed Brutus' [Dummett]
18. Thought / E. Abstraction / 8. Abstractionism Critique
To abstract from spoons (to get the same number as the forks), the spoons must be indistinguishable too [Dummett]
19. Language / C. Assigning Meanings / 5. Fregean Semantics
Fregean semantics assumes a domain articulated into individual objects [Dummett]
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius]
26. Natural Theory / C. Causation / 1. Causation
Causation by absence is not real causation, but part of our explanatory practices [Mumford/Anjum]
Causation may not be transitive. Does a fire cause itself to be extinguished by the sprinklers? [Mumford/Anjum]
26. Natural Theory / C. Causation / 4. Naturalised causation
Causation is the passing around of powers [Mumford/Anjum]
26. Natural Theory / C. Causation / 6. Causation as primitive
We take causation to be primitive, as it is hard to see how it could be further reduced [Mumford/Anjum]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causation doesn't have two distinct relata; it is a single unfolding process [Mumford/Anjum]
A collision is a process, which involves simultaneous happenings, but not instantaneous ones [Mumford/Anjum]
Does causation need a third tying ingredient, or just two that meet, or might there be a single process? [Mumford/Anjum]
Sugar dissolving is a process taking time, not one event and then another [Mumford/Anjum]
26. Natural Theory / C. Causation / 8. Particular Causation / d. Selecting the cause
Privileging one cause is just an epistemic or pragmatic matter, not an ontological one [Mumford/Anjum]
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
Coincidence is conjunction without causation; smoking causing cancer is the reverse [Mumford/Anjum]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Is a cause because of counterfactual dependence, or is the dependence because there is a cause? [Mumford/Anjum]
Occasionally a cause makes no difference (pre-emption, perhaps) so the counterfactual is false [Mumford/Anjum]
Cases of preventing a prevention may give counterfactual dependence without causation [Mumford/Anjum]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
Nature can be interfered with, so a cause never necessitates its effects [Mumford/Anjum]
We assert causes without asserting that they necessitate their effects [Mumford/Anjum]
Necessary causation should survive antecedent strengthening, but no cause can always survive that [Mumford/Anjum]
26. Natural Theory / D. Laws of Nature / 7. Strictness of Laws
A 'ceteris paribus' clause implies that a conditional only has dispositional force [Mumford/Anjum]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
There may be necessitation in the world, but causation does not supply it [Mumford/Anjum]
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
Laws are nothing more than descriptions of the behaviour of powers [Mumford/Anjum]
If laws are equations, cause and effect must be simultaneous (or the law would be falsified)! [Mumford/Anjum]
27. Natural Reality / C. Space / 3. Points in Space
Why should the limit of measurement be points, not intervals? [Dummett]
27. Natural Reality / G. Biology / 3. Evolution
Archelaus said life began in a primeval slime [Archelaus, by Schofield]
