2. Reason / D. Definition / 4. Real Definition
Real definitions don't just single out a thing; they must also explain its essence [Koslicki]
2. Reason / D. Definition / 7. Contextual Definition
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 / A. Nature of Mathematics / 3. Nature of Numbers / c. Priority of numbers
Addition of quantities is prior to ordering, as shown in cyclic domains like angles [Dummett]
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / a. Units
A number is a multitude composed of units [Dummett]
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / e. Counting by correlation
We understand 'there are as many nuts as apples' as easily by pairing them as by counting them [Dummett]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / a. Axioms for numbers
It is more explanatory if you show how a number is constructed from basic entities and relations [Koslicki]
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 / C. Structure of Existence / 1. Grounding / b. Relata of grounding
The relata of grounding are propositions or facts, but for dependence it is objects and their features [Koslicki]
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 / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
We can bring dispositions into existence, as in creating an identifier [Dennett, by Mumford]
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]
9. Objects / D. Essence of Objects / 2. Types of Essence
Modern views want essences just to individuate things across worlds and times [Koslicki]
9. Objects / D. Essence of Objects / 4. Essence as Definition
For Fine, essences are propositions true because of identity, so they are just real definitions [Koslicki]
We need a less propositional view of essence, and so must distinguish it clearly from real definitions [Koslicki]
9. Objects / D. Essence of Objects / 13. Nominal Essence
Words are fixed by being attached to similarity clusters, without mention of 'essences' [Dennett]
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]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / b. Primary/secondary
Light wavelengths entering the eye are only indirectly related to object colours [Dennett]
14. Science / C. Induction / 1. Induction
Brains are essentially anticipation machines [Dennett]
14. Science / D. Explanation / 1. Explanation / b. Aims of explanation
A good explanation captures the real-world dependence among the phenomena [Koslicki]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / a. Consciousness
We can't draw a clear line between conscious and unconscious [Dennett]
Perhaps the brain doesn't 'fill in' gaps in consciousness if no one is looking. [Dennett]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
Conscious events can only be explained in terms of unconscious events [Dennett]
15. Nature of Minds / B. Features of Minds / 3. Privacy
We can know a lot of what it is like to be a bat, and nothing important is unknown [Dennett]
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
"Qualia" can be replaced by complex dispositional brain states [Dennett]
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
We can't assume that dispositions will remain normal when qualia have been inverted [Dennett]
15. Nature of Minds / B. Features of Minds / 7. Blindsight
In peripheral vision we see objects without their details, so blindsight is not that special [Dennett]
Blindsight subjects glean very paltry information [Dennett]
16. Persons / B. Nature of the Self / 4. Presupposition of Self
People accept blurred boundaries in many things, but insist self is All or Nothing [Dennett]
16. Persons / B. Nature of the Self / 7. Self and Body / c. Self as brain controller
The psychological self is an abstraction, not a thing in the brain [Dennett]
16. Persons / E. Rejecting the Self / 2. Self as Social Construct
Selves are not soul-pearls, but artefacts of social processes [Dennett]
16. Persons / E. Rejecting the Self / 3. Narrative Self
We tell stories about ourselves, to protect, control and define who we are [Dennett]

The brain is controlled by shifting coalitions, guided by good purposeful habits [Dennett]
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
If an epiphenomenon has no physical effects, it has to be undetectable [Dennett]
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
Dualism wallows in mystery, and to accept it is to give up [Dennett]
17. Mind and Body / C. Functionalism / 6. Homuncular Functionalism
All functionalism is 'homuncular', of one grain size or another [Dennett]
17. Mind and Body / E. Mind as Physical / 3. Eliminativism
Visual experience is composed of neural activity, which we find pleasing [Dennett]
It is arbitrary to say which moment of brain processing is conscious [Dennett]
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 / 3. Abstracta by Ignoring
We can abstract to a dependent entity by blocking out features of its bearer [Koslicki]
18. Thought / E. Abstraction / 7. Abstracta by Equivalence
There is no reason why abstraction by equivalence classes should be called 'logical' [Dummett, by Tait]

Why should the limit of measurement be points, not intervals? [Dummett]
