1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
As coherence expands its interrelations become steadily tighter, culminating only in necessary truth [Dancy,J]
3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
The correspondence theory also has the problem that two sets of propositions might fit the facts equally well [Dancy,J]
3. Truth / D. Coherence Truth / 1. Coherence Truth
Rescher says that if coherence requires mutual entailment, this leads to massive logical redundancy [Dancy,J]
If one theory is held to be true, all the other theories appear false, because they can't be added to the true one [Dancy,J]
3. Truth / D. Coherence Truth / 2. Coherence Truth Critique
Even with a tight account of coherence, there is always the possibility of more than one set of coherent propositions [Dancy,J]
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]
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
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]
7. Existence / D. Theories of Reality / 2. Realism
Realism says that most perceived objects exist, and have some of their perceived properties [Dancy,J]
7. Existence / D. Theories of Reality / 8. Facts / a. Facts
Events are picked out by descriptions, and facts by whole sentences [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 / 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]
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
A pupil who lacks confidence may clearly know something but not be certain of it [Dancy,J]
11. Knowledge Aims / B. Certain Knowledge / 3. Fallibilism
If senses are fallible, then being open to correction is an epistemological virtue [Dancy,J]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / a. Naïve realism
Naïve direct realists hold that objects retain all of their properties when unperceived [Dancy,J]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / b. Direct realism
Scientific direct realism says we know some properties of objects directly [Dancy,J]
Maybe we are forced from direct into indirect realism by the need to explain perceptual error [Dancy,J]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / c. Representative realism
Internal realism holds that we perceive physical objects via mental objects [Dancy,J]
Indirect realism depends on introspection, the time-lag, illusions, and neuroscience [Dancy,J, by PG]
11. Knowledge Aims / C. Knowing Reality / 2. Phenomenalism
Phenomenalism includes possible experiences, but idealism only refers to actual experiences [Dancy,J]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / a. Idealism
Eliminative idealists say there are no objects; reductive idealists say objects exist as complex experiences [Dancy,J]
11. Knowledge Aims / C. Knowing Reality / 4. Solipsism
Extreme solipsism only concerns current experience, but it might include past and future [Dancy,J]
12. Knowledge Sources / A. A Priori Knowledge / 5. A Priori Synthetic
Knowing that a cow is not a horse seems to be a synthetic a priori truth [Dancy,J]
12. Knowledge Sources / B. Perception / 1. Perception
Perception is either direct realism, indirect realism, or phenomenalism [Dancy,J]
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 / 2. Qualities in Perception / e. Primary/secondary critique
For direct realists the secondary and primary qualities seem equally direct [Dancy,J]
We can't grasp the separation of quality types, or what a primary-quality world would be like [Dancy,J]
12. Knowledge Sources / B. Perception / 4. Sense Data / a. Sense-data theory
The traditional supports for the sense datum theory were seeing double and specks before one's eyes [Crane]
We can be looking at distant stars which no longer actually exist [Dancy,J]
One can taste that the wine is sour, and one can also taste the sourness of the wine [Crane]
12. Knowledge Sources / B. Perception / 4. Sense Data / b. Nature of sense-data
It is not clear from the nature of sense data whether we should accept them as facts [Dancy,J]
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 / 7. Causal Perception
Appearances don't guarantee reality, unless the appearance is actually caused by the reality [Dancy,J]
Perceptual beliefs may be directly caused, but generalisations can't be [Dancy,J]
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]
12. Knowledge Sources / E. Direct Knowledge / 4. Memory
If perception and memory are indirect, then two things stand between mind and reality [Dancy,J]
Memories aren't directly about the past, because time-lags and illusions suggest representation [Dancy,J]
Phenomenalism about memory denies the past, or reduces it to present experience [Dancy,J]
I can remember plans about the future, and images aren't essential (2+3=5) [Dancy,J]
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / a. Agrippa's trilemma
Foundations are justified by non-beliefs, or circularly, or they need no justification [Dancy,J]
13. Knowledge Criteria / A. Justification Problems / 3. Internal or External / a. Pro-internalism
For internalists we must actually know that the fact caused the belief [Dancy,J]
Internalists tend to favour coherent justification, but not the coherence theory of truth [Dancy,J]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism
Foundationalism requires inferential and non-inferential justification [Dancy,J]
Foundationalists must accept not only the basic beliefs, but also rules of inference for further progress [Dancy,J]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / b. Basic beliefs
If basic beliefs can be false, falsehood in non-basic beliefs might by a symptom [Dancy,J]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
Beliefs can only be infallible by having almost no content [Dancy,J]
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
Coherentism gives a possible justification of induction, and opposes scepticism [Dancy,J]
Idealists must be coherentists, but coherentists needn't be idealists [Dancy,J]
For coherentists justification and truth are not radically different things [Dancy,J]
13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / b. Pro-coherentism
If it is empirical propositions which have to be coherent, this eliminates coherent fiction [Dancy,J]
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]
Externalism could even make belief unnecessary (e.g. in animals) [Dancy,J]
13. Knowledge Criteria / C. External Justification / 2. Causal Justification
How can a causal theory of justification show that all men die? [Dancy,J]
Causal theories don't allow for errors in justification [Dancy,J]
13. Knowledge Criteria / C. External Justification / 8. Social Justification
Coherentism moves us towards a more social, shared view of knowledge [Dancy,J]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
What is the point of arguing against knowledge, if being right undermines your own argument? [Dancy,J]
14. Science / C. Induction / 6. Bayes's Theorem
Probabilities can only be assessed relative to some evidence [Dancy,J]
15. Nature of Minds / A. Nature of Mind / 4. Other Minds / d. Other minds by analogy
The argument from analogy rests on one instance alone [Dancy,J]
You can't separate mind and behaviour, as the analogy argument attempts [Dancy,J]
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 / 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]
19. Language / A. Nature of Meaning / 5. Meaning as Verification
Verificationism (the 'verification principle') is an earlier form of anti-realism [Dancy,J]
Logical positivism implies foundationalism, by dividing weak from strong verifications [Dancy,J]
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
If the meanings of sentences depend on other sentences, how did we learn language? [Dancy,J]
19. Language / F. Communication / 6. Interpreting Language / b. Indeterminate translation
There is an indeterminacy in juggling apparent meanings against probable beliefs [Dancy,J]
19. Language / F. Communication / 6. Interpreting Language / c. Principle of charity
Charity makes native beliefs largely true, and Humanity makes them similar to ours [Dancy,J]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / c. Ethical intuitionism
If there are intuited moral facts, why should we care about them? [Dancy,J]
Internalists say that moral intuitions are motivating; externalist say a desire is also needed [Dancy,J]
Obviously judging an action as wrong gives us a reason not to do it [Dancy,J]
Moral facts are not perceived facts, but perceived reasons for judgements [Dancy,J]
22. Metaethics / B. Value / 1. Nature of Value / a. Nature of value
The base for values has grounds, catalysts and intensifiers [Dancy,J, by Orsi]
25. Social Practice / F. Life Issues / 6. Animal Rights
Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley]
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 / 4. Naturalised causation
A cause has its effects in virtue of its properties [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]
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
The regularity theory explains a causal event by other items than the two that are involved [Crane]
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
It seems that 'exists' could sometimes be a predicate [Crane]
