2. Reason / D. Definition / 9. Recursive Definition
Dedekind proved definition by recursion, and thus proved the basic laws of arithmetic [Dedekind, by Potter]
4. Formal Logic / F. Set Theory ST / 3. Types of Set / d. Infinite Sets
An infinite set maps into its own proper subset [Dedekind, by Reck/Price]
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / f. Axiom of Infinity V
We have the idea of self, and an idea of that idea, and so on, so infinite ideas are available [Dedekind, by Potter]
4. Formal Logic / G. Formal Mereology / 1. Mereology
Dedekind originally thought more in terms of mereology than of sets [Dedekind, by Potter]
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
The theory of descriptions supports internalism, since they are thinkable when the object is non-existent [Crane]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / a. Numbers
Numbers are free creations of the human mind, to understand differences [Dedekind]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / c. Priority of numbers
Dedekind defined the integers, rationals and reals in terms of just the natural numbers [Dedekind, by George/Velleman]
Order, not quantity, is central to defining numbers [Dedekind, by Monk]
Ordinals can define cardinals, as the smallest ordinal that maps the set [Dedekind, by Heck]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / e. Ordinal numbers
Dedekind's ordinals are just members of any progression whatever [Dedekind, by Russell]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / i. Reals from cuts
Dedekind's axiom that his Cut must be filled has the advantages of theft over honest toil [Dedekind, by Russell]
Dedekind says each cut matches a real; logicists say the cuts are the reals [Dedekind, by Bostock]
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
In counting we see the human ability to relate, correspond and represent [Dedekind]
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / b. Mark of the infinite
A system S is said to be infinite when it is similar to a proper part of itself [Dedekind]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / a. Axioms for numbers
Dedekind gives a base number which isn't a successor, then adds successors and induction [Dedekind, by Hart,WD]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / d. Peano arithmetic
Zero is a member, and all successors; numbers are the intersection of sets satisfying this [Dedekind, by Bostock]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / e. Peano arithmetic 2nd-order
Categoricity implies that Dedekind has characterised the numbers, because it has one domain [Rumfitt on Dedekind]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / f. Mathematical induction
Induction is proved in Dedekind, an axiom in Peano; the latter seems simpler and clearer [Dedekind, by Russell]

Dedekind originated the structuralist conception of mathematics [Dedekind, by MacBride]
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / b. Varieties of structuralism
Dedekindian abstraction talks of 'positions', where Cantorian abstraction talks of similar objects [Dedekind, by Fine,K]

Aesthetic properties of thing supervene on their physical properties [Crane]
7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
Constitution (as in a statue constituted by its marble) is supervenience without identity [Crane]
8. Modes of Existence / B. Properties / 7. Emergent Properties
The distinction between 'resultant' properties (weight) and 'emergent' properties is a bit vague [Crane]
If mental properties are emergent they add a new type of causation, and physics is not complete [Crane]
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Properties are causes [Crane]
9. Objects / A. Existence of Objects / 3. Objects in Thought
A thing is completely determined by all that can be thought concerning it [Dedekind]
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Traditional substance is separate from properties and capable of independent existence [Crane]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Maybe beliefs don't need to be conscious, if you are not conscious of the beliefs guiding your actions [Crane]
Maybe there are two kinds of belief - 'de re' beliefs and 'de dicto' beliefs [Crane]
11. Knowledge Aims / A. Knowledge / 6. Knowing How
Many cases of knowing how can be expressed in propositional terms (like how to get somewhere) [Crane]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities
Phenol-thio-urea tastes bitter to three-quarters of people, but to the rest it is tasteless, so which is it? [Crane]
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
One can taste that the wine is sour, and one can also taste the sourness of the wine [Crane]
The traditional supports for the sense datum theory were seeing double and specks before one's eyes [Crane]
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
If we smell something we are aware of the smell separately, but we don't perceive a 'look' when we see [Crane]
The problems of perception disappear if it is a relation to an intentional state, not to an object or sense datum [Crane]
12. Knowledge Sources / B. Perception / 6. Inference in Perception
If perception is much richer than our powers of description, this suggests that it is non-conceptual [Crane]
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
The adverbial theory of perceptions says it is the experiences which have properties, not the objects [Crane]
13. Knowledge Criteria / C. External Justification / 1. External Justification
Is knowledge just a state of mind, or does it also involve the existence of external things? [Crane]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
The core of the consciousness problem is the case of Mary, zombies, and the Hard Question [Crane]
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Intentionalism does not require that all mental states be propositional attitudes [Crane]
Object-directed attitudes like love are just as significant as propositional attitudes [Crane]
15. Nature of Minds / B. Features of Minds / 5. Qualia / a. Nature of qualia
If someone removes their glasses the content of experience remains, but the quality changes [Crane]
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
Pains have a region of the body as their intentional content, not some pain object [Crane]
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
Weak intentionalism says qualia are extra properties; strong intentionalism says they are intentional [Crane]
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
With inverted qualia a person's experiences would change, but their beliefs remain the same [Crane]
17. Mind and Body / A. Mind-Body Dualism / 1. Dualism
Descartes did not think of minds as made of a substance, because they are not divisible [Crane]
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
Functionalism defines mental states by their causal properties, which rules out epiphenomenalism [Crane]
17. Mind and Body / D. Property Dualism / 1. Reductionism critique
The problems of misrepresentation and error have dogged physicalist reductions of intentionality [Crane]
17. Mind and Body / D. Property Dualism / 3. Property Dualism
Properties dualism says mental properties are distinct from physical, despite a single underlying substance [Crane]
17. Mind and Body / D. Property Dualism / 4. Emergentism
Non-reductive physicalism seeks an explanation of supervenience, but emergentists accept it as basic [Crane]
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
If mental supervenes on the physical, then every physical cause will be accompanied by a mental one [Crane]
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Identity theory is either of particular events, or of properties, depending on your theory of causation [Crane]
Physicalism may be the source of the mind-body problem, rather than its solution [Crane]
17. Mind and Body / E. Mind as Physical / 5. Causal Argument
Overdetermination occurs if two events cause an effect, when each would have caused it alone [Crane]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / a. Physicalism critique
The completeness of physics must be an essential component of any physicalist view of mind [Crane]
17. Mind and Body / E. Mind as Physical / 7. Anti-Physicalism / c. Knowledge argument
Experience teaches us propositions, because we can reason about our phenomenal experience [Crane]
18. Thought / C. Content / 2. Ideas
By an 'idea' I mean not an actual thought, but the resources we can draw on to think [Leibniz]
18. Thought / C. Content / 5. Twin Earth
The Twin Earth argument depends on reference being determined by content, which may be false. [Crane]
18. Thought / C. Content / 6. Broad Content
Broad content entails the existence of the object of the thought [Crane]
18. Thought / C. Content / 8. Intension
In intensional contexts, truth depends on how extensions are conceived. [Crane]
18. Thought / E. Abstraction / 3. Abstracta by Ignoring
Dedekind said numbers were abstracted from systems of objects, leaving only their position [Dedekind, by Dummett]
We derive the natural numbers, by neglecting everything of a system except distinctness and order [Dedekind]
18. Thought / E. Abstraction / 8. Abstractionism Critique
Dedekind has a conception of abstraction which is not psychologistic [Dedekind, by Tait]
26. Natural Theory / C. Causation / 2. Types of cause
Causation can be seen in counterfactual terms, or as increased probability, or as energy flow [Crane]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causes are properties, not events, because properties are what make a difference in a situation [Crane]
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
It seems that 'exists' could sometimes be a predicate [Crane]
