1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
Philosophers are good at denying the obvious [Hawley]
3. Truth / A. Truth Problems / 2. Defining Truth
Truth definitions don't produce a good theory, because they go beyond your current language [Halbach]
3. Truth / F. Semantic Truth / 1. Tarski's Truth / c. Meta-language for truth
In semantic theories of truth, the predicate is in an object-language, and the definition in a metalanguage [Halbach]
3. Truth / G. Axiomatic Truth / 1. Axiomatic Truth
Should axiomatic truth be 'conservative' - not proving anything apart from implications of the axioms? [Halbach]
If truth is defined it can be eliminated, whereas axiomatic truth has various commitments [Halbach]
Instead of a truth definition, add a primitive truth predicate, and axioms for how it works [Halbach]
Axiomatic theories of truth need a weak logical framework, and not a strong metatheory [Halbach]
3. Truth / H. Deflationary Truth / 2. Deflationary Truth
Deflationists say truth merely serves to express infinite conjunctions [Halbach]
4. Formal Logic / F. Set Theory ST / 1. Set Theory
To prove the consistency of set theory, we must go beyond set theory [Halbach]
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
We can use truth instead of ontologically loaded second-order comprehension assumptions about properties [Halbach]
5. Theory of Logic / E. Structures of Logic / 7. Predicates in Logic
Instead of saying x has a property, we can say a formula is true of x - as long as we have 'true' [Halbach]
5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive
Part of the sense of a proper name is a criterion of the thing's identity [Hawley]
7. Existence / C. Structure of Existence / 5. Supervenience / d. Humean supervenience
A homogeneous rotating disc should be undetectable according to Humean supervenience [Hawley]
7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality
Non-linguistic things cannot be indeterminate, because they don't have truth-values at all [Hawley]
Maybe for the world to be vague, it must be vague in its foundations? [Hawley]
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
Epistemic vagueness seems right in the case of persons [Hawley]
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
Supervaluation refers to one vaguely specified thing, through satisfaction by everything in some range [Hawley]
Supervaluationism takes what the truth-value would have been if indecision was resolved [Hawley]
8. Modes of Existence / B. Properties / 1. Nature of Properties
Maybe the only properties are basic ones like charge, mass and spin [Hawley]
9. Objects / A. Existence of Objects / 1. Physical Objects
An object is 'natural' if its stages are linked by certain non-supervenient relations [Hawley]
9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail
Are sortals spatially maximal - so no cat part is allowed to be a cat? [Hawley]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
The modal features of statue and lump are disputed; when does it stop being that statue? [Hawley]
Perdurantists can adopt counterpart theory, to explain modal differences of identical part-sums [Hawley]
9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
Vagueness is either in our knowledge, in our talk, or in reality [Hawley]
Indeterminacy in objects and in properties are not distinct cases [Hawley]
9. Objects / C. Structure of Objects / 6. Constitution of an Object
The constitution theory is endurantism plus more than one object in a place [Hawley]
Constitution theory needs sortal properties like 'being a sweater' to distinguish it from its thread [Hawley]
If the constitution view says thread and sweater are two things, why do we talk of one thing? [Hawley]
9. Objects / E. Objects over Time / 2. Objects that Change
'Adverbialism' explains change by saying an object has-at-some-time a given property [Hawley]
Presentism solves the change problem: the green banana ceases, so can't 'relate' to the yellow one [Hawley]
The problem of change arises if there must be 'identity' of a thing over time [Hawley]
9. Objects / E. Objects over Time / 3. Three-Dimensionalism
Endurance theory can relate properties to times, or timed instantiations to properties [Hawley]
Endurance is a sophisticated theory, covering properties, instantiation and time [Hawley]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
How does perdurance theory explain our concern for our own future selves? [Hawley]
Perdurance needs an atemporal perspective, to say that the object 'has' different temporal parts [Hawley]
If an object is the sum of all of its temporal parts, its mass is staggeringly large! [Hawley]
Perdurance says things are sums of stages; Stage Theory says each stage is the thing [Hawley]
If a life is essentially the sum of its temporal parts, it couldn't be shorter or longer than it was? [Hawley]
9. Objects / E. Objects over Time / 5. Temporal Parts
Stages must be as fine-grained in length as change itself, so any change is a new stage [Hawley]
Stage Theory seems to miss out the link between stages of the same object [Hawley]
Stage Theory says every stage is a distinct object, which gives too many objects [Hawley]
An isolated stage can't be a banana (which involves suitable relations to other stages) [Hawley]
Stages of one thing are related by extrinsic counterfactual and causal relations [Hawley]
The stages of Stage Theory seem too thin to populate the world, or to be referred to [Hawley]
9. Objects / F. Identity among Objects / 8. Leibniz's Law
If two things might be identical, there can't be something true of one and false of the other [Hawley]
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
To decide whether something is a counterpart, we need to specify a relevant sortal concept [Hawley]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Evolutionary explanations look to the past or the group, not to the individual [Stout,R]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Not all explanation is causal. We don't explain a painting's beauty, or the irrationality of root-2, that way [Stout,R]
16. Persons / D. Continuity of the Self / 5. Concerns of the Self
On any theory of self, it is hard to explain why we should care about our future selves [Hawley]
20. Action / A. Definition of Action / 1. Action Theory
Philosophy of action studies the nature of agency, and of deliberate actions [Stout,R]
Agency is causal processes that are sensitive to justification [Stout,R]
20. Action / A. Definition of Action / 2. Duration of an Action
If one action leads to another, does it cause it, or is it part of it? [Stout,R]
Mental states and actions need to be separate, if one is to cause the other [Stout,R]
Are actions bodily movements, or a sequence of intention-movement-result? [Stout,R]
20. Action / A. Definition of Action / 3. Actions and Events
I do actions, but not events, so actions are not events [Stout,R]
20. Action / A. Definition of Action / 4. Action as Movement
Bicycle riding is not just bodily movement - you also have to be on the bicycle [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / a. Nature of intentions
The rationalistic approach says actions are intentional when subject to justification [Stout,R]
The causal theory says that actions are intentional when intention (or belief-desire) causes the act [Stout,R]
Deciding what to do usually involves consulting the world, not our own minds [Stout,R]
Should we study intentions in their own right, or only as part of intentional action? [Stout,R]
You can have incompatible desires, but your intentions really ought to be consistent [Stout,R]
The normativity of intentions would be obvious if they were internal promises [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / b. Types of intention
Intentional agency is seen in internal precursors of action, and in external reasons for the act [Stout,R]
Speech needs sustained intentions, but not prior intentions [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / d. Group intentions
Bratman has to treat shared intentions as interrelated individual intentions [Stout,R]
A request to pass the salt shares an intention that the request be passed on [Stout,R]
An individual cannot express the intention that a group do something like moving a piano [Stout,R]
An intention is a goal to which behaviour is adapted, for an individual or for a group [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / b. Volitionism
If the action of walking is just an act of will, then movement of the legs seems irrelevant [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / c. Agent causation
If you don't mention an agent, you aren't talking about action [Stout,R]
Most philosophers see causation as by an event or state in the agent, rather than the whole agent [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / d. Weakness of will
If you can judge one act as best, then do another, this supports an inward-looking view of agency [Stout,R]
20. Action / C. Motives for Action / 1. Acting on Desires
Maybe your emotions arise from you motivations, rather than being their cause [Stout,R]
For an ascetic a powerful desire for something is a reason not to implement it [Stout,R]
20. Action / C. Motives for Action / 3. Acting on Reason / c. Reasons as causes
Beliefs, desires and intentions are not events, so can't figure in causal relations [Stout,R]
A standard view says that the explanation of an action is showing its rational justification [Stout,R]
In order to be causal, an agent's reasons must be internalised as psychological states [Stout,R]
20. Action / C. Motives for Action / 4. Responsibility for Actions
An action is only yours if you produce it, rather than some state or event within you [Stout,R]
There may be a justification relative to a person's view, and yet no absolute justification [Stout,R]
20. Action / C. Motives for Action / 5. Action Dilemmas / b. Double Effect
Describing a death as a side-effect rather than a goal may just be good public relations [Stout,R]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Aristotelian causation involves potentiality inputs into processes (rather than a pair of events) [Stout,R]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Causation is nothing more than the counterfactuals it grounds? [Hawley]
27. Natural Reality / D. Time / 3. Parts of Time / b. Instants
Time could be discrete (like integers) or dense (rationals) or continuous (reals) [Hawley]
