1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
8558
|
One system has properties, powers, events, similarity and substance
|
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
8559
|
Analysis aims at internal relationships, not reduction
|
2. Reason / A. Nature of Reason / 9. Limits of Reason
8594
|
People have had good reasons for thinking that the circle has been squared
|
5. Theory of Logic / I. Semantics of Logic / 3. Logical Truth
15091
|
Restrict 'logical truth' to formal logic, rather than including analytic and metaphysical truths
|
7. Existence / D. Theories of Reality / 3. Anti-realism
8596
|
Inability to measure equality doesn't make all lengths unequal
|
8597
|
We couldn't verify the earth's rotation if everyone simultaneously fell asleep
|
8. Modes of Existence / B. Properties / 1. Nature of Properties
15092
|
Formerly I said properties are individuated by essential causal powers and causing instantiation [Shoemaker]
|
15095
|
A property's causal features are essential, and only they fix its identity
|
15097
|
I claim that a property has its causal features in all possible worlds
|
8. Modes of Existence / B. Properties / 5. Natural Properties
8543
|
Genuine properties are closely related to genuine changes
|
8551
|
Properties must be essentially causal if we can know and speak about them
|
8557
|
To ascertain genuine properties, examine the object directly
|
8. Modes of Existence / B. Properties / 10. Properties as Predicates
15761
|
We should abandon the idea that properties are the meanings of predicate expressions
|
15756
|
Some truths are not because of a thing's properties, but because of the properties of related things
|
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
8547
|
One power can come from different properties; a thing's powers come from its properties
|
15758
|
Things have powers in virtue of (which are entailed by) their properties
|
8549
|
Properties are functions producing powers, and powers are functions producing effects
|
15094
|
I now deny that properties are cluster of powers, and take causal properties as basic
|
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
8545
|
A causal theory of properties focuses on change, not (say) on abstract properties of numbers
|
15757
|
'Square', 'round' and 'made of copper' show that not all properties are dispositional
|
15759
|
The identity of a property concerns its causal powers
|
15760
|
Properties are clusters of conditional powers
|
15762
|
Could properties change without the powers changing, or powers change without the properties changing?
|
8552
|
If properties are separated from causal powers, this invites total elimination
|
4040
|
The notions of property and of causal power are parts of a single system of related concepts
|
15765
|
Actually, properties are individuated by causes as well as effects
|
12678
|
Shoemaker says all genuine properties are dispositional [Ellis]
|
14534
|
Shoemaker moved from properties as powers to properties bestowing powers [Mumford/Anjum]
|
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
8548
|
Dispositional predicates ascribe powers, and the rest ascribe properties
|
8. Modes of Existence / D. Universals / 2. Need for Universals
9485
|
Universals concern how things are, and how they could be [Bird]
|
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
8550
|
Triangular and trilateral are coextensive, but different concepts; but powers and properties are the same
|
9. Objects / D. Essence of Objects / 15. Against Essentialism
8555
|
There is no subset of properties which guarantee a thing's identity
|
10. Modality / A. Necessity / 5. Metaphysical Necessity
15099
|
If something is possible, but not nomologically possible, we need metaphysical possibility
|
10. Modality / B. Possibility / 1. Possibility
8554
|
Possible difference across worlds depends on difference across time in the actual world
|
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
15101
|
Once you give up necessity as a priori, causal necessity becomes the main type of necessity
|
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
15764
|
'Conceivable' is either not-provably-false, or compatible with what we know?
|
15098
|
Empirical evidence shows that imagining a phenomenon can show it is possible
|
15100
|
Imagination reveals conceptual possibility, where descriptions avoid contradiction or incoherence
|
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible
8562
|
It is possible to conceive what is not possible
|
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
5691
|
The adverbial account of sensation says not 'see a red image' but be 'appeared to redly'
|
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
8593
|
Maybe billions of changeless years have elapsed since my last meal
|
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
8556
|
Grueness is not, unlike green and blue, associated with causal potential
|
15096
|
'Grue' only has causal features because of its relation to green
|
16. Persons / C. Self-Awareness / 1. Introspection
5687
|
For true introspection, must we be aware that we are aware of our mental events?
|
5688
|
Empirical foundationalism says basic knowledge is self-intimating, and incorrigible or infallible
|
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
1389
|
If memory is the sole criterion of identity, we ought to use it for other people too
|
1390
|
Bodily identity is one criterion and memory another, for personal identity [PG]
|
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
8542
|
If causality is between events, there must be reference to the properties involved
|
26. Natural Theory / C. Causation / 9. General Causation / a. Constant conjunction
8598
|
If things turn red for an hour and then explode, we wouldn't say the redness was the cause
|
26. Natural Theory / D. Laws of Nature / 5. Laws from Universals
15093
|
We might say laws are necessary by combining causal properties with Armstrong-Dretske-Tooley laws
|
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
8560
|
If causal laws describe causal potentialities, the same laws govern properties in all possible worlds
|
15763
|
If properties are causal, then causal necessity is a species of logical necessity
|
8561
|
If a world has different causal laws, it must have different properties
|
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / d. Knowing essences
8553
|
It looks as if the immutability of the powers of a property imply essentiality
|
27. Natural Reality / D. Time / 1. Nature of Time / e. Eventless time
4226
|
If three regions 'freeze' every three, four and five years, after sixty years everything stops for a year [Lowe]
|
8595
|
If three regions freeze every 3rd, 4th and 5th year, they all freeze together every 60 years
