1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined
Maybe what distinguishes philosophy from science is its pursuit of necessary truths [Sider]
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
The observation of human blindness and weakness is the result of all philosophy [Hume]
1. Philosophy / E. Nature of Metaphysics / 2. Possibility of Metaphysics
Metaphysical enquiry can survive if its conclusions are tentative [Sider]
Your metaphysics is 'cheating' if your ontology won't support the beliefs you accept [Sider]
1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
Metaphysics is not about what exists or is true or essential; it is about the structure of reality [Sider]
Extreme doubts about metaphysics also threaten to undermine the science of unobservables [Sider]
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
It seems unlikely that the way we speak will give insights into the universe [Sider]
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
If we suspect that a philosophical term is meaningless, we should ask what impression it derives from [Hume]
Conceptual analysts trust particular intuitions much more than general ones [Sider]
1. Philosophy / G. Scientific Philosophy / 1. Aims of Science
All experimental conclusions assume that the future will be like the past [Hume]
2. Reason / A. Nature of Reason / 7. Status of Reason
Reason is and ought to be the slave of the passions [Hume]
2. Reason / D. Definition / 13. Against Definition
It seems possible for a correct definition to be factually incorrect, as in defining 'contact' [Sider]
Philosophical concepts are rarely defined, and are not understood by means of definitions [Sider]
2. Reason / E. Argument / 3. Analogy
An analogy begins to break down as soon as the two cases differ [Hume]
All reasoning concerning matters of fact is based on analogy (with similar results of similar causes) [Hume]
3. Truth / A. Truth Problems / 3. Value of Truth
We don't care about plain truth, but truth in joint-carving terms [Sider]
3. Truth / B. Truthmakers / 5. What Makes Truths / b. Objects make truths
Orthodox truthmaker theories make entities fundamental, but that is poor for explanation [Sider]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / b. Terminology of PL
'Theorems' are formulas provable from no premises at all [Sider]
4. Formal Logic / B. Propositional Logic PL / 3. Truth Tables
Truth tables assume truth functionality, and are just pictures of truth functions [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / c. System D
Intuitively, deontic accessibility seems not to be reflexive, but to be serial [Sider]
In D we add that 'what is necessary is possible'; then tautologies are possible, and contradictions not necessary [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / f. System B
System B introduces iterated modalities [Sider]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / h. System S5
S5 is the strongest system, since it has the most valid formulas, because it is easy to be S5-valid [Sider]
4. Formal Logic / D. Modal Logic ML / 5. Epistemic Logic
Epistemic accessibility is reflexive, and allows positive and negative introspection (KK and K¬K) [Sider]
4. Formal Logic / D. Modal Logic ML / 6. Temporal Logic
We can treat modal worlds as different times [Sider]
4. Formal Logic / D. Modal Logic ML / 7. Barcan Formula
Converse Barcan Formula: □∀αφ→∀α□φ [Sider]
The Barcan Formula ∀x□Fx→□∀xFx may be a defect in modal logic [Sider]
System B is needed to prove the Barcan Formula [Sider]
The Barcan schema implies if X might have fathered something, there is something X might have fathered [Sider]
4. Formal Logic / E. Nonclassical Logics / 2. Intuitionist Logic
You can employ intuitionist logic without intuitionism about mathematics [Sider]

'Gunk' is an object in which proper parts all endlessly have further proper parts [Sider]
4. Formal Logic / G. Formal Mereology / 3. Axioms of Mereology
Which should be primitive in mereology - part, or overlap? [Sider]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
There is a real issue over what is the 'correct' logic [Sider]
'It is raining' and 'it is not raining' can't be legislated, so we can't legislate 'p or ¬p' [Sider]
5. Theory of Logic / A. Overview of Logic / 6. Classical Logic
Classical logic is good for mathematics and science, but less good for natural language [Sider]
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
The most popular account of logical consequence is the semantic or model-theoretic one [Sider]
Maybe logical consequence is more a matter of provability than of truth-preservation [Sider]
Maybe logical consequence is impossibility of the premises being true and the consequent false [Sider]
Maybe logical consequence is a primitive notion [Sider]
Modal accounts of logical consequence are simple necessity, or essential use of logical words [Sider]
5. Theory of Logic / B. Logical Consequence / 3. Deductive Consequence |-
A 'theorem' is an axiom, or the last line of a legitimate proof [Sider]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
Define logical constants by role in proofs, or as fixed in meaning, or as topic-neutral [Sider]
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
When a variable is 'free' of the quantifier, the result seems incapable of truth or falsity [Sider]
5. Theory of Logic / E. Structures of Logic / 5. Functions in Logic
A 'total' function must always produce an output for a given domain [Sider]
5. Theory of Logic / F. Referring in Logic / 3. Property (λ-) Abstraction
λ can treat 'is cold and hungry' as a single predicate [Sider]
5. Theory of Logic / H. Proof Systems / 2. Axiomatic Proof
Good axioms should be indisputable logical truths [Sider]
No assumptions in axiomatic proofs, so no conditional proof or reductio [Sider]
5. Theory of Logic / H. Proof Systems / 3. Proof from Assumptions
Proof by induction 'on the length of the formula' deconstructs a formula into its accepted atoms [Sider]
Induction has a 'base case', then an 'inductive hypothesis', and then the 'inductive step' [Sider]
5. Theory of Logic / H. Proof Systems / 4. Natural Deduction
'Tonk' is supposed to follow the elimination and introduction rules, but it can't be so interpreted [Sider]
Natural deduction helpfully allows reasoning with assumptions [Sider]
5. Theory of Logic / H. Proof Systems / 6. Sequent Calculi
We can build proofs just from conclusions, rather than from plain formulae [Sider]
5. Theory of Logic / I. Semantics of Logic / 1. Semantics of Logic
Valuations in PC assign truth values to formulas relative to variable assignments [Sider]
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
The semantical notion of a logical truth is validity, being true in all interpretations [Sider]
It is hard to say which are the logical truths in modal logic, especially for iterated modal operators [Sider]
5. Theory of Logic / J. Model Theory in Logic / 1. Logical Models
In model theory, first define truth, then validity as truth in all models, and consequence as truth-preservation [Sider]
5. Theory of Logic / K. Features of Logics / 4. Completeness
In a complete logic you can avoid axiomatic proofs, by using models to show consequences [Sider]
5. Theory of Logic / K. Features of Logics / 6. Compactness
Compactness surprisingly says that no contradictions can emerge when the set goes infinite [Sider]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / e. Peano arithmetic 2nd-order
A single second-order sentence validates all of arithmetic - but this can't be proved axiomatically [Sider]
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / d. Hume's Principle
Two numbers are equal if all of their units correspond to one another [Hume]
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / a. Mathematical empiricism
Reason assists experience in discovering laws, and in measuring their application [Hume]
7. Existence / A. Nature of Existence / 2. Types of Existence
There is no medium state between existence and non-existence [Hume]
7. Existence / A. Nature of Existence / 4. Abstract Existence
We can't think about the abstract idea of triangles, but only of particular triangles [Hume]
7. Existence / B. Change in Existence / 2. Processes
Four-dimensionalism sees things and processes as belonging in the same category [Sider]
7. Existence / C. Structure of Existence / 5. Supervenience / a. Nature of supervenience
Supervenience is a modal connection [Sider]
7. Existence / C. Structure of Existence / 6. Fundamentals / b. Types of fundamental
Is fundamentality in whole propositions (and holistic), or in concepts (and atomic)? [Sider]
Tables and chairs have fundamental existence, but not fundamental natures [Sider]
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
Unlike things, stuff obeys unrestricted composition and mereological essentialism [Sider]
7. Existence / D. Theories of Reality / 9. States of Affairs
We must distinguish 'concrete' from 'abstract' and necessary states of affairs. [Sider]
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
A 'precisification' of a trivalent interpretation reduces it to a bivalent interpretation [Sider]
Supervaluational logic is classical, except when it adds the 'Definitely' operator [Sider]
A 'supervaluation' assigns further Ts and Fs, if they have been assigned in every precisification [Sider]
We can 'sharpen' vague terms, and then define truth as true-on-all-sharpenings [Sider]
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
Accept the ontology of your best theory - and also that it carves nature at the joints [Sider]
8. Modes of Existence / A. Relations / 1. Nature of Relations
A relation is a feature of multiple objects taken together [Sider]
8. Modes of Existence / B. Properties / 3. Types of Properties
A property is intrinsic if an object alone in the world can instantiate it [Sider]
8. Modes of Existence / B. Properties / 6. Categorical Properties
Proper ontology should only use categorical (actual) properties, not hypothetical ones [Sider]
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Predicates can be 'sparse' if there is a universal, or if there is a natural property or relation [Sider]
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
Individuals consist of 'compresent' tropes [Bacon,John]
A trope is a bit of a property or relation (not an exemplification or a quality) [Bacon,John]
Trope theory is ontologically parsimonious, with possibly only one-category [Bacon,John]
8. Modes of Existence / C. Powers and Dispositions / 1. Powers
Power is the possibility of action, as discovered by experience [Hume]
There may well be powers in things, with which we are quite unacquainted [Hume]
8. Modes of Existence / C. Powers and Dispositions / 7. Against Powers
We have no idea of powers, because we have no impressions of them [Hume]
The distinction between a power and its exercise is entirely frivolous [Hume]
We cannot form an idea of a 'power', and the word is without meaning [Hume]
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
Momentary impressions are wrongly identified with one another on the basis of resemblance [Hume, by Quine]
If we see a resemblance among objects, we apply the same name to them, despite their differences [Hume]
9. Objects / A. Existence of Objects / 5. Individuation / a. Individuation
Individuation is only seeing that a thing is stable and continuous over time [Hume]
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
If sortal terms fix the kind and the persistence conditions, we need to know what kinds there are [Sider]
9. Objects / B. Unity of Objects / 2. Substance / e. Substance critique
The only meaning we have for substance is a collection of qualities [Hume]
Aristotelians propose accidents supported by substance, but they don't understand either of them [Hume]
9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
If Tib is all of Tibbles bar her tail, when Tibbles loses her tail, two different things become one [Sider]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
Artists 'create' statues because they are essentially statues, and so lack identity with the lump of clay [Sider]
9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects
The stage view of objects is best for dealing with coincident entities [Sider]
9. Objects / C. Structure of Objects / 5. Composition of an Object
'Composition as identity' says that an object just is the objects which compose it [Sider]
9. Objects / D. Essence of Objects / 12. Essential Parts
Mereological essentialism says an object's parts are necessary for its existence [Sider]
9. Objects / D. Essence of Objects / 15. Against Essentialism
Essence (even if nonmodal) is not fundamental in metaphysics [Sider]
9. Objects / E. Objects over Time / 1. Objects over Time
A change more obviously destroys an identity if it is quick and observed [Hume]
Changing a part can change the whole, not absolutely, but by its proportion of the whole [Hume]
9. Objects / E. Objects over Time / 2. Objects that Change
If a republic can retain identity through many changes, so can an individual [Hume]
If identity survives change or interruption, then resemblance, contiguity or causation must unite the parts of it [Hume]
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
Three-dimensionalists assert 'enduring', being wholly present at each moment, and deny 'temporal parts' [Sider]
Some might say that its inconsistency with time travel is a reason to favour three-dimensionalism [Sider]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
Four-dimensionalists assert 'temporal parts', 'perduring', and being spread out over time [Sider]
4D says intrinsic change is difference between successive parts [Sider]
4D says each spatiotemporal object must have a temporal part at every moment at which it exists [Sider]
9. Objects / E. Objects over Time / 5. Temporal Parts
Temporal parts exist, but are not prior building blocks for objects [Sider]
Temporal parts are instantaneous [Sider]
How can an instantaneous stage believe anything, if beliefs take time? [Sider]
Four-dimensionalism says temporal parts are caused (through laws of motion) by previous temporal parts [Sider]
9. Objects / E. Objects over Time / 7. Intermittent Objects
If a ruined church is rebuilt, its relation to its parish makes it the same church [Hume]
9. Objects / E. Objects over Time / 8. Continuity of Rivers
We accept the identity of a river through change, because it is the river's nature [Hume]
9. Objects / E. Objects over Time / 9. Ship of Theseus
The purpose of the ship makes it the same one through all variations [Hume]
The ship undergoes 'asymmetric' fission, where one candidate is seen as stronger [Sider]
9. Objects / F. Identity among Objects / 1. Concept of Identity
Multiple objects cannot convey identity, because we see them as different [Hume]
Both number and unity are incompatible with the relation of identity [Hume]
9. Objects / F. Identity among Objects / 5. Self-Identity
'An object is the same with itself' is meaningless; it expresses unity, not identity [Hume]
Saying an object is the same with itself is only meaningful over a period of time [Hume]
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
The identity of indiscernibles is necessarily true, if being a member of some set counts as a property [Sider]
9. Objects / F. Identity among Objects / 8. Leibniz's Law
If you say Leibniz's Law doesn't apply to 'timebound' properties, you are no longer discussing identity [Sider]
10. Modality / A. Necessity / 3. Types of Necessity
'Strong' necessity in all possible worlds; 'weak' necessity in the worlds where the relevant objects exist [Sider]
10. Modality / A. Necessity / 5. Metaphysical Necessity
Maybe metaphysical accessibility is intransitive, if a world in which I am a frog is impossible [Sider]
10. Modality / A. Necessity / 6. Logical Necessity
Logical truths must be necessary if anything is [Sider]
10. Modality / A. Necessity / 10. Impossibility
Nothing we clearly imagine is absolutely impossible [Hume]
10. Modality / A. Necessity / 11. Denial of Necessity
Necessity only exists in the mind, and not in objects [Hume]
10. Modality / B. Possibility / 6. Probability
We transfer the frequency of past observations to our future predictions [Hume]
10. Modality / B. Possibility / 7. Chance
There is no such thing as chance [Hume]
10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
'If B hadn't shot L someone else would have' if false; 'If B didn't shoot L, someone else did' is true [Sider]
10. Modality / C. Sources of Modality / 1. Sources of Necessity
Humeans say that we decide what is necessary [Sider]
Modal terms in English are entirely contextual, with no modality outside the language [Sider]
10. Modality / C. Sources of Modality / 3. Necessity by Convention
If truths are necessary 'by convention', that seems to make them contingent [Sider]
Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider]
10. Modality / C. Sources of Modality / 4. Necessity from Concepts
Humeans says mathematics and logic are necessary because that is how our concept of necessity works [Sider]
10. Modality / C. Sources of Modality / 5. Modality from Actuality
The world does not contain necessity and possibility - merely how things are [Sider]
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds
Maybe possible worlds are just sets of possible tropes [Bacon,John]
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
Transworld identity is not a problem in de dicto sentences, which needn't identify an individual [Sider]
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Counterparts rest on similarity, so there are many such relations in different contexts [Sider]
10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects
Barcan Formula problem: there might have been a ghost, despite nothing existing which could be a ghost [Sider]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
Belief is stronger, clearer and steadier than imagination [Hume]
11. Knowledge Aims / A. Knowledge / 4. Belief / b. Elements of beliefs
Belief can't be a concept plus an idea, or we could add the idea to fictions [Hume]
Belief is just a particular feeling attached to ideas of objects [Hume]
11. Knowledge Aims / A. Knowledge / 4. Belief / d. Cause of beliefs
Beliefs are built up by resemblance, contiguity and causation [Hume]
Belief is a feeling, independent of the will, which arises from uncontrolled and unknown causes [Hume]
'Natural beliefs' are unavoidable, whatever our judgements [Hume, by Strawson,G]
11. Knowledge Aims / C. Knowing Reality / 1. Perceptual Realism / c. Representative realism
Hume says objects are not a construction, but an imaginative leap [Hume, by Robinson,H]
12. Knowledge Sources / A. A Priori Knowledge / 9. A Priori from Concepts
Relations of ideas are known by thought, independently from the world [Hume]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / e. Primary/secondary critique
If secondary qualities (e.g. hardness) are in the mind, so are primary qualities like extension [Hume]
12. Knowledge Sources / B. Perception / 3. Representation
It never occurs to people that they only experience representations, not the real objects [Hume]
12. Knowledge Sources / D. Empiricism / 1. Empiricism
All reasoning about facts is causal; nothing else goes beyond memory and senses [Hume]
A proposition cannot be intelligible or consistent, if the perceptions are not so [Hume]
All ideas are copies of impressions [Hume]
Hume is loose when he says perceptions of different strength are different species [Reid on Hume]
If books don't relate ideas or explain facts, commit them to the flames [Hume]
Impressions are our livelier perceptions, Ideas the less lively ones [Hume]
All objects of enquiry are Relations of Ideas, or Matters of Fact [Hume]
12. Knowledge Sources / D. Empiricism / 2. Associationism
All ideas are connected by Resemblance, Contiguity in time or place, and Cause and Effect [Hume]
Associationism results from having to explain intentionality just with sense-data [Robinson,H on Hume]
12. Knowledge Sources / D. Empiricism / 4. Pro-Empiricism
How could Adam predict he would drown in water or burn in fire? [Hume]
We can only invent a golden mountain by combining experiences [Hume]
Events are baffling before experience, and obvious after experience [Hume]
You couldn't reason at all if you lacked experience [Hume]
We cannot form the idea of something we haven't experienced [Hume]
Only madmen dispute the authority of experience [Hume]
When definitions are pushed to the limit, only experience can make them precise [Hume]
12. Knowledge Sources / D. Empiricism / 5. Empiricism Critique
Hume mistakenly lumps sensations and perceptions together as 'impressions' [Scruton on Hume]
Even Hume didn't include mathematics in his empiricism [Hume, by Kant]
If a person had a gap in their experience of blue shades, they could imaginatively fill it in [Hume]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / c. Empirical foundations
Reasons for belief must eventually terminate in experience, or they are without foundation [Hume]
13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / f. Foundationalism critique
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 / C. External Justification / 8. Social Justification
Mathematicians only accept their own proofs when everyone confims them [Hume]
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]
13. Knowledge Criteria / D. Scepticism / 2. Types of Scepticism
Mitigated scepticism sensibly confines our enquiries to the narrow capacity of human understanding [Hume]
Hume became a total sceptic, because he believed that reason was a deception [Hume, by Kant]
13. Knowledge Criteria / D. Scepticism / 3. Illusion Scepticism
Examples of illusion only show that sense experience needs correction by reason [Hume]
13. Knowledge Criteria / D. Scepticism / 6. Scepticism Critique
It is a very extravagant aim of the sceptics to destroy reason and argument by means of reason and argument [Hume]
The main objection to scepticism is that no good can come of it [Hume]
14. Science / B. Scientific Theories / 2. Aim of Science
A theory which doesn't fit nature is unexplanatory, even if it is true [Sider]
14. Science / B. Scientific Theories / 8. Ramsey Sentences
If I used Ramsey sentences to eliminate fundamentality from my theory, that would be a real loss [Sider]
14. Science / C. Induction / 1. Induction
The idea of inductive evidence, around 1660, made Hume's problem possible [Hume, by Hacking]
14. Science / C. Induction / 2. Aims of Induction
We assume similar secret powers behind similar experiences, such as the nourishment of bread [Hume]
14. Science / C. Induction / 3. Limits of Induction
All inferences from experience are effects of custom, not reasoning [Hume]
Induction can't prove that the future will be like the past, since induction assumes this [Hume]
If we infer causes from repetition, this explains why we infer from a thousand objects what we couldn't infer from one [Hume]
Reason cannot show why reliable past experience should extend to future times and remote places [Hume]
Fools, children and animals all learn from experience [Hume]
14. Science / C. Induction / 4. Reason in Induction
Premises can support an argument without entailing it [Pollock/Cruz on Hume]
Hume just shows induction isn't deduction [Williams,M on Hume]
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Problem predicates in induction don't reflect the structure of nature [Sider]
Two applications of 'grue' do not guarantee a similarity between two things [Sider]
14. Science / C. Induction / 6. Bayes's Theorem
Bayes produces weird results if the prior probabilities are bizarre [Sider]
14. Science / D. Explanation / 1. Explanation / a. Explanation
Explanations must cite generalisations [Sider]
14. Science / D. Explanation / 3. Best Explanation / b. Ultimate explanation
If the ultimate explanation is a list of entities, no laws, patterns or mechanisms can be cited [Sider]
15. Nature of Minds / B. Features of Minds / 4. Intentionality / a. Nature of intentionality
Intentionality is too superficial to appear in the catalogue of ultimate physics [Sider]
15. Nature of Minds / C. Capacities of Minds / 2. Imagination
Memory, senses and understanding are all founded on the imagination [Hume]
15. Nature of Minds / C. Capacities of Minds / 7. Seeing Resemblance
A picture of a friend strengthens our idea of him, by resemblance [Hume]
Hume needs a notion which includes degrees of resemblance [Shoemaker on Hume]
General ideas are the connection by resemblance to some particular [Hume]
Hume does not distinguish real resemblances among degrees of resemblance [Shoemaker on Hume]
15. Nature of Minds / C. Capacities of Minds / 8. Remembering Contiguity
When I am close to (contiguous with) home, I feel its presence more nearly [Hume]
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
An object made by a saint is the best way to produce thoughts of him [Hume]
Our awareness of patterns of causation is too important to be left to slow and uncertain reasoning [Hume]
16. Persons / B. Nature of the Self / 5. Self as Associations
Experiences are logically separate, but factually linked by simultaneity or a feeling of continuousness [Ayer on Hume]
Hume's 'bundle' won't distinguish one mind with ten experiences from ten minds [Searle on Hume]
A person is just a fast-moving bundle of perceptions [Hume]
The parts of a person are always linked together by causation [Hume]
Hume gives us an interesting sketchy causal theory of personal identity [Perry on Hume]
A person is simply a bundle of continually fluctuating perceptions [Hume]
16. Persons / C. Self-Awareness / 3. Limits of Introspection
Introspection always discovers perceptions, and never a Self without perceptions [Hume]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
Memory only reveals personal identity, by showing cause and effect [Hume]
We use memory to infer personal actions we have since forgotten [Hume]
Memory not only reveals identity, but creates it, by producing resemblances [Hume]
Who thinks that because you have forgotten an incident you are no longer that person? [Hume]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / b. Self as mental continuity
Causation unites our perceptions, by producing, destroying and modifying each other [Hume]
Are self and substance the same? Then how can self remain if substance changes? [Hume]
16. Persons / D. Continuity of the Self / 2. Mental Continuity / c. Inadequacy of mental continuity
Perceptions are distinct, so no connection between them can ever be discovered [Hume]
16. Persons / E. Rejecting the Self / 4. Denial of the Self
A continuous lifelong self must be justified by a single sustained impression, which we don't have [Hume]
When I introspect I can only observe my perceptions, and never a self which has them [Hume]
We pretend our perceptions are continuous, and imagine a self to fill the gaps [Hume]
Identity in the mind is a fiction, like that fiction that plants and animals stay the same [Hume]
We have no impression of the self, and we therefore have no idea of it [Hume]
Does an oyster with one perception have a self? Would lots of perceptions change that? [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 / 7. Compatibilism
Liberty is merely acting according to the will, which anyone can do if they are not in chains [Hume]
Hume makes determinism less rigid by removing the necessity from causation [Trusted on Hume]
19. Language / A. Nature of Meaning / 6. Meaning as Use
Prior to conventions, not all green things were green? [Sider]
19. Language / E. Analyticity / 2. Analytic Truths
Conventions are contingent and analytic truths are necessary, so that isn't their explanation [Sider]
19. Language / E. Analyticity / 4. Analytic/Synthetic Critique
Analyticity has lost its traditional role, which relied on truth by convention [Sider]
20. Action / A. Definition of Action / 2. Duration of an Action
If one event causes another, the two events must be wholly distinct [Hume, by Wilson/Schpall]
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Only experience teaches us about our wills [Hume]
20. Action / C. Motives for Action / 3. Acting on Reason / a. Practical reason
For Hume, practical reason has little force, because we can always modify our desires [Hume, by Graham]
20. Action / C. Motives for Action / 3. Acting on Reason / b. Intellectualism
Reason alone can never be a motive to any action of the will [Hume]
20. Action / C. Motives for Action / 4. Responsibility for Actions
You can only hold people responsible for actions which arise out of their character [Hume]
Praise and blame can only be given if an action proceeds from a person's character and disposition [Hume]
20. Action / C. Motives for Action / 5. Action Dilemmas / a. Dilemmas
Moral questions can only be decided by common opinion [Hume]
21. Aesthetics / A. Aesthetic Experience / 2. Aesthetic Attitude
Forget about beauty; just concentrate on the virtues of delicacy and discernment admired in critics [Hume, by Scruton]
21. Aesthetics / A. Aesthetic Experience / 3. Taste
Strong sense, delicate sentiment, practice, comparisons, and lack of prejudice, are all needed for good taste [Hume]
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
If you deny all necessity and causation, then our character is not responsible for our crime [Hume]
Repentance gets rid of guilt, which shows that responsibility arose from the criminal principles in the mind [Hume]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / h. Expressivism
We cannot discover vice by studying a wilful murder; that only arises from our own feelings [Hume]
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
Modern science has destroyed the Platonic synthesis of scientific explanation and morality [Hume, by Taylor,C]
The problem of getting to 'ought' from 'is' would also apply in getting to 'owes' or 'needs' [Anscombe on Hume]
You can't move from 'is' to 'ought' without giving some explanation or reason for the deduction [Hume]
Virtues and vices are like secondary qualities in perception, found in observers, not objects [Hume]
22. Metaethics / B. Value / 2. Values / f. Altruism
The human heart has a natural concern for public good [Hume]
22. Metaethics / B. Value / 2. Values / g. Love
We have no natural love of mankind, other than through various relationships [Hume]
22. Metaethics / B. Value / 2. Values / i. Self-interest
Total selfishness is not irrational [Hume]
23. Ethics / A. Egoism / 1. Ethical Egoism
No moral theory is of any use if it doesn't serve the interests of the individual concerned [Hume]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue
Personal Merit is the possession of useful or agreeable mental qualities [Hume]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / c. Motivation for virtue
All virtues benefit either the public, or the individual who possesses them [Hume]
23. Ethics / C. Virtue Theory / 3. Virtues / c. Justice
Justice only exists to support society [Hume]
If we all naturally had everything we could ever desire, the virtue of justice would be irrelevant [Hume]
23. Ethics / C. Virtue Theory / 4. External Goods / d. Friendship
Friendship without community spirit misses out on the main part of virtue [Hume]
23. Ethics / D. Deontological Ethics / 2. Duty
Moral philosophy aims to show us our duty [Hume]
23. Ethics / D. Deontological Ethics / 6. Motivation for Duty
Conclusions of reason do not affect our emotions or decisions to act [Hume]
23. Ethics / E. Utilitarianism / 1. Utilitarianism
Virtue just requires careful calculation and a preference for the greater happiness [Hume]
23. Ethics / E. Utilitarianism / 3. Motivation for Altruism
No one would cause pain to a complete stranger who happened to be passing [Hume]
Nature makes private affections come first, because public concerns are spread too thinly [Hume]
24. Political Theory / A. Basis of a State / 3. Natural Values / b. Natural equality
People must have agreed to authority, because they are naturally equal, prior to education [Hume]
24. Political Theory / B. Nature of a State / 1. Purpose of a State
The safety of the people is the supreme law [Hume]
The only purpose of government is to administer justice, which brings security [Hume]
24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract
The idea that society rests on consent or promises undermines obedience [Hume]
We no more give 'tacit assent' to the state than a passenger carried on board a ship while asleep [Hume]
The people would be amazed to learn that government arises from their consent [Hume]
24. Political Theory / B. Nature of a State / 3. Constitutions
It would be absurd if even a free constitution did not impose restraints, for the public good [Hume]
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
Modern monarchies are (like republics) rule by law, rather than by men [Hume]
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
Nobility either share in the power of the whole, or they compose the power of the whole [Hume]
24. Political Theory / C. Ruling a State / 3. Government / a. Government
Society prefers helpful lies to harmful truth [Hume]
25. Social Practice / A. Freedoms / 3. Free speech
No government has ever suffered by being too tolerant of philosophy [Hume]
25. Social Practice / A. Freedoms / 7. Freedom to leave
Poor people lack the knowledge or wealth to move to a different state [Hume]
25. Social Practice / B. Equalities / 4. Economic equality
If you equalise possessions, people's talents will make them unequal again [Hume]
25. Social Practice / C. Rights / 1. Basis of Rights
There are two kinds of right - to power, and to property [Hume]
25. Social Practice / C. Rights / 4. Property rights
Hume thought (unlike Locke) that property is a merely conventional relationship [Hume, by Fogelin]
We all know that the history of property is founded on injustices [Hume]
It is an exaggeration to say that property is the foundation of all government [Hume]
25. Social Practice / F. Life Issues / 4. Suicide
If suicide is wrong because only God disposes of our lives, it must also be wrong to save lives [Hume]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
We can discover some laws of nature, but never its ultimate principles and causes [Hume]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / a. Early Modern matter
We have no good concept of solidity or matter, because accounts of them are all circular [Hume]
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 / 3. Final causes
The idea of a final cause is very uncertain and unphilosophical [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 / 8. Particular Causation / c. Conditions of causation
For Hume a constant conjunction is both necessary and sufficient for causation [Hume, by Crane]
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]
Causation is just invariance, as long as it is described in general terms [Quine on Hume]
If impressions, memories and ideas only differ in vivacity, nothing says it is memory, or repetition [Whitehead on Hume]
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
Hume seems to presuppose necessary connections between mental events [Kripke on Hume]
That events could be uncaused is absurd; I only say intuition and demonstration don't show this [Hume]
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 / 11. Against Laws of Nature
The notion of law doesn't seem to enhance physical theories [Sider]
Many of the key theories of modern physics do not appear to be 'laws' [Sider]
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
Maybe motion is a dynamical quantity intrinsic to a thing at a particular time [Sider]
27. Natural Reality / C. Space / 4. Substantival Space
Space has real betweenness and congruence structure (though it is not the Euclidean concepts) [Sider]
27. Natural Reality / C. Space / 6. Space-Time
Space is 3D and lacks a direction; time seems connected to causation [Sider]
The central question in the philosophy of time is: How alike are time and space? [Sider]
27. Natural Reality / D. Time / 1. Nature of Time / f. Eternalism
The spotlight theorists accepts eternal time, but with a spotlight of the present moving across it [Sider]
27. Natural Reality / D. Time / 1. Nature of Time / g. Growing block
Between presentism and eternalism is the 'growing block' view - the past is real, the future is not [Sider]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
For Presentists there must always be a temporal vantage point for any description [Sider]
Presentists must deny truths about multiple times [Sider]
27. Natural Reality / D. Time / 2. Passage of Time / c. Tenses and time
Talk using tenses can be eliminated, by reducing it to indexical connections for an utterance [Sider]
27. Natural Reality / D. Time / 2. Passage of Time / f. Tenseless (B) series
The B-theory is adequate, except that it omits to say which time is present [Sider]
The B-series involves eternalism, and the reduction of tense [Sider]
28. God / A. Divine Nature / 3. Divine Perfections
We can't assume God's perfections are like our ideas or like human attributes [Hume]
28. God / B. Proving God / 1. Proof of God
The objects of theological reasoning are too big for our minds [Hume]
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]
No being's non-existence can imply a contradiction, so its existence cannot be proved a priori [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / a. Cosmological Proof
A chain of events requires a cause for the whole as well as the parts, yet the chain is just a sum of parts [Hume]
If something must be necessary so that something exists rather than nothing, why can't the universe be necessary? [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
The thing which contains order must be God, so see God where you see order [Hume]
28. God / B. Proving God / 3. Proofs of Evidence / c. Teleological Proof critique
How can we pronounce on a whole after a brief look at a very small part? [Hume]
Design cannot prove a unified Deity. Many men make a city, so why not many gods for a world? [Hume]
From a ship you would judge its creator a genius, not a mere humble workman [Hume]
This excellent world may be the result of a huge sequence of trial-and-error [Hume]
Humans renew their species sexually. If there are many gods, would they not do the same? [Hume]
Creation is more like vegetation than human art, so it won't come from reason [Hume]
This Creator god might be an infant or incompetent or senile [Hume]
Motion often begins in matter, with no sign of a controlling agent [Hume]
The universe could settle into superficial order, without a designer [Hume]
Ideas arise from objects, not vice versa; ideas only influence matter if they are linked [Hume]
A surprise feature of all products of 9 looks like design, but is actually a necessity [Hume]
Why would we infer an infinite creator from a finite creation? [Hume]
Analogy suggests that God has a very great human mind [Hume]
The universe may be the result of trial-and-error [Hume]
Order may come from an irrational source as well as a rational one [Hume]
From our limited view, we cannot tell if the universe is faulty [Hume]
You can't infer the cause to be any greater than its effect [Hume]
If the divine cause is proportional to its effects, the effects are finite, so the Deity cannot be infinite [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]
It can't be more rational to believe in natural laws than miracles if the laws are not rational [Ishaq on 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]
29. Religion / D. Religious Issues / 2. Immortality / a. Immortality
If all of my perceptions were removed by death, nothing more is needed for total annihilation [Hume]
