Midterm Vocab Flashcards
Naive Realism
Believe that a sensory experience’s phenomenal character consists in
1) external world objects
2) subject’s perspective upon those obects and properties
Naive Realists believe that a sensory experience’s phenomenal character consists in (2)
1) external world objects and their properties.
2) subject’s perspective upon those obects and properties
MGF Martin’s 2 main questions
1) Is sensory experience constitutively dependent on the existence of its object?
2) Is sensory experience constitutively sufficient for the existence of its object?
Do naive realists believe that sensory experience is dependent on the existence of its object?
Yes
Do naive realists think that sensory experience is sufficient for the existence of its object?
No
Why don’t naive realists think sensory experience is sufficient for the existence of its object?
(like sense datum theorists) they insist that the sensory experience of an object requires awareness (rather than mere representation) of that object.
___ take their account to faithfully capture how things seem to those who reflect upon their sensory experience.
Naive realists
What would a naive realist say about the perception of a raspberry bush?
Your sensory experience’s phenomenal character is then determined by
-The raspberry itself
-Those of the raspberry’s properties of which you’re aware
-Perspectival factors (point of view, lighting, etc.)
MGF Martin’s “Limits of Self-Awareness” uses the argument _______ to target naive realism and establish it’s insconsistency.
the argument from hallucination
Common Kind Assumption
“Whatever kind of mental event occurs when on is veridically perceiving some scene, that kind of event can occur whether or not one is perceiving” Martin 2004, p. 40
Experiential Naturalism
Our sense experiences are subject to the causal order, such as physical causes (neuro-physiological causes/conditions) and psychological causes (if disjoint from physical causes)
-Martin
What are the two assumptions that MGF Martin identifies in Naive Realism?
1) Common Kind Assumtion
2) Experiential Naturalism
What is MGF martin’s argument aganst naive realism (6)
1) When a subject percieves a raspberry bush, she is aware of a bush whose existence does not depend on her awareness of it (mind-independent), and this awareness could not be obtained in the absence of the bush. (Naive realism)
2) The subject experiences the same thing when they perceive the bush vs. when they are hallucinating (Common Kind Assumption).
3) But, the experience of a hallucination must have a sufficient physical cause (Experiential Naturalism)
4) The experience includes awareness of an object for whose existence the experience is sufficient, or the experience does not involve awareness of an object. (from 3).
5) If an experience has an object of awareness for whose existence the experience is sufficient, the object is mind-dependent.
6) (from applying 4 and 5 to 2) the subject who perceives the bush perceives a mind-dependent object, or she is not aware of the object.
Why does MGF argue that naive realism is inconsistent?
Because it argues that objects of awareness are simultaneously not objects of awareness, and that they are mind-independent and mind-dependent at the same time.
What is the traditional response to MGF Martin’s argument?
Reject premise 1, and therefore reject naive realism.
What is a disjunctivist?
Someone who denies the Common Kind Assumption of naive realism.
Does disjunctivism entail naive realism?
No, as technically you could reject both the common kind assumption (be a disjunctivist) and naive realism as a whole.
Does naive realism entail disjunctivism?
MGF Martin says yes: to be a naive realist you must also be a disjunctivist.
Not everyone agrees
What are the causal grounds for accepting the Common Kind Assumption? (4)
1) When a subject sees X, there is some causal condition, C, in the subject’s body which determined the chance of the occurrence of that event of seeing.
2) It is possible given the laws of nature that C should occur in the subject even if no potential object for perception is present in the subject’s environment.
3) Same cause = same effect.
When 2 situations involve the same causal conditions, the chances for the occurence of such an effect are the same in both situations.
4) whatever mental state occurs in 1, the same experience occurs in 2 (Common Kind Assumption)
Where does a disjunctivist (and naive realist) resist the causal grounds for the Common Kind Assumption? (3 ways)
-Usually reject the 3rd premise: same proximate cause, same effect.
1) Deny that causal relations between individual events require general causal laws (Anscombe).
ex - A can cause B without a law saying A must cause B
2) Deny causal relations due to the special case of causation between physical events and psychological events (which do not always necessitate laws)
3) Generates the worng result when applied to causes and effects that are relational
Relational state of affairs involves _________________
two or more entities standing in specific relations to one another.
Relational state of affairs exists only if (2)
1) the relevant entities exist
2) the relevant entities are appropriately situated to enter into the relevant relation.
(these conditions are not always causal conditions)
How do relational state of affairs relate to naive realism?
Naive realists believe that seeing an object requires the existence of the object, and that the object be appropriately situated so as to be perceived.
In the absence of these non-causal conditions, a neural event that causes an event of seeing in one situation may not in another situation.
Naive realists believe that seeing an object requires _________ (2)
the existence of the object, and that the object be appropriately situated so as to be perceived.
How do you modify the 3rd premise of MGF’s argument against naive realism, to accommodate relational states of affairs?
3) When two situations involve the same causal conditions, and do not differ in any non-causal conditions for the occurence of some effect, the chances for the occurrence of such an effect are the same in both situations.
(Martin thinks this makes a further problem for disjunctivists/naive realists).
What is MGF Martin’s solution to his argument against naive realism? (controversial)
Negative Epistemic Disjunctivism
Negative Epistemic Disjunctivism says that for hallucinations whose causes match those of veridical visual experiences, there is nothing more to the phenomenal character of such experiences than _________
that of being indescriminable from the corresponding veridical experiences.
How does Martin relate disjunctivism to naive realism
Argues that naive realists must deny the Common Kind Assumption, and therefore be disjunctivists
What is the reverse causal argument?
After the 3rd modified premise of the causal argument from before:
4) No non-causal condition obtains in the hallucinatory case which does not also obtain in the veridical case.
5) Whatever kind of experience occurs in the hallucinatory case, it is possible that the same kind of experience occurs in the veridical case.
“Screening Off Problem” for disjunctivism
If a kind to which perception belongs is also present when hallucinating, how can the kind to which only the perception belongs play a role in explaining the features/effects of sensory experience?
Martin argues for ______ to prevent the screening off problem
Negative Epistemic Disjunctivism (NED)
3 important results of Negative Epistemic Disjunctivism
1) Being indiscriminable from a veridical experience is a kind to which both hallucination and veridical experiences belong.
2) Being indiscriminable from a veridical experience is not a property that screens off the characteristic features of veridical experiences.
3) Being indiscriminable from a veridical experience can explain why causally matching hallucinations have a subset of the effects corresponding with veridical experiences.
____ take their account to faithfully capture how htings seem to those who reflect upon their sensory experience.
Naive realists
How do naive realists think things seem when we perceive something?
It seems that experience presents mind-independent external world objects and their features.

we represent them when we hallucinate; at best we represent an intentional object.
A naive realist believes that sensory experience is ___________ the existence of its object.
dependent on but not sufficient for

awareness (rather than mere representation) of an object.
Naive realists believe that sensory experience’s phenomenal character consists in _______________.
the external world objects and properties that the experience presents, together with the subject’s perspective upon those objects and properties.
Naive realism is a form of
direct realism
Naive realism does not entail that any two experiences that present the same objects and properties must possess ___________
the same phenomenal character
To a naive realist, sameness of phenomenal character requires both
-Sameness of presented items
-Sameness of perspectival factors
Naive realists must deny that two experiences can have the same phenomenal character despite _______.
not presenting the same mind-dependent objects.
Naive realism allows that features of a percieving subject can make a ______ (as opposed to ______) difference to sensory phenomenology
Constitutive, causal
Perspectival factors do not smuggle _______ or __________ into the naive realist’s account of phenomenal character.
representational content or sense data
Campbell argues that naive realism posits experience as a 3-place relation between
-An object
-An experiencer
-A standpoint
Campell argues for naive realism by arguing that representationalists cannot ______
Representationalists cannot provide the required explanation of perception’s thought-securing role.
6 points of Campbell’s argument for Naive Realism
- thought-like representational contents that they are accessible to the subject in multiple ways (meaning of a sentence, content of a belief, conclusion of premises, etc.)
- If sensory experiences are just a class of mental states with thought-like representational contents, the representational content of sensory experience is accessible to the subject in multiple ways.
- Having a sensory experience is just one way of being in a mental state that has this kind of representational content.
- The claim that sensory experiences are a class of mental states with thought-like representational contents is inconsistent with the claim that perception plays an essential role in enabling us to think about external world objects.
- Naive realists can explain how perception plays an essential role in enabling us to think about external world objects.
- Only naive realists can explain this.
How does the argument from hallucination pose a challenge for naive realism
- During hallucinations, the direct object of a subject’s awareness cannot be an external world object with which she is in perceptual contact.
- To claim that hallucinations/veridical experiences involve direct awareness of different sorts of objects, we need a proper reason to believe this claim.
- There are some veridical expereince where the subject’s point of view is indistiguishible from the hallucinatory experience.
**4. How things seem from the subjects point of view provides no grounds that hallucinatory/veridical experiences involve direct awareness of different sorts of objects.
**
- Absent of some other ground, hallucinatory/veridical experiences involve direct awareness of the same sort of objects.
- Veridical experience does not involve direct awareness of (presumably mind-independent) external world objects.

properties it in fact has.
Representationalists claim that illusory experiences represent the object which you are in perceptual contact as having ___________
Properties it in fact lacks

ordinary objects and their properties
Representationalist Argument from Transparency (3) (Tye)
1) A right account ought to respect the transparency of sensory experience.
2) Only representationalism respects the transparency of sensory experience.
3) We ought to accept representationalism.
Argument for representationlism, from the explanatory role of sensory experience (3)
1) Veridical/illusory/hallucinatory experiences perform some of the same explanatory roles.
2) Representationalism provides the best account of these explanatory symmetries between these experiences.
3) So, we ought to accept representationalism.
What are the candidate roles of all experience (veridical/illusory/hallucinatory)? (3)
1) Justify the same beliefs about the external world.
2) Provide the same reasons for action.
3) any sensory experience of an F object enables a subject to think about F.
McDowell argues that only representationalism affords representational content a ___________.
fundamental role in sensory experience.
What is the epistemic challenge for opponents of representationalism?
Either accommodate a larger role for representational content or construct an alternative account of why it is rational to form certain beliefs in response to sensory experience.
Argument for representationalism, from vision science
1) We perceive the world in virtue of perceptual processing, that constructs/manipulates representations, which encode information about external properties.
2) A right account of perception must respect our best science of perception (Methodological Naturalism)
3) Respecting our best science requires that visual experiences are representations that encode information about external properties.
What is an objection to the argument for representationalism from vision science
It presupposes, without argument, an optional view about the relationship between sub-personal perceptual processing and sensory experience.
How is representationalism challenged by the possibility of spectrum inversion?
Two people identifying the same coloured object as different colours, despite having the same colour terms, discrimination of objects by colour, etc.
How would a sense datum theorist challenge representationalism?
By defending the phenomenal principle
What problem does the “screening off” problem pose to naive realists?
Introspection can’t be reliable because what is enough to explain veridical cases is also enough to explain hallucinatory cases.
the most recent cause in a causal chain
proximate cause
Negative Epistemic Disjunctivism specifically applies to which types of hallucinations?
Hallucinations with matching proximate causes to veridical cases (not all hallucinations)
For hallucinations whose proximate causes match those of a veridical visual experience, there is nothing more to the phenomenal character of such experiences than that of being indiscriminible from the corresponding veridical experiences.
Negative Epistemic Disjunctivism
Martin exploits the naive realist’s response to the ______________ to reconstruct a Reverse Causal Argument that, together with the screening off problem, commits naive realist disjunctivists to: ___________
Causal Argument for the Common Kind Assumption, Negative Epistemic Disjunctivism

View where sensory experience’s phenomenal character (how things seem to a subject) is exhausted by the experience’s representational content
Pure representationalism
View where how things seem to a subject is just how the subject’s experience represents the world as being.
Representationalists (or intentionalists) follow Anscombe in holding that a fundamental account of sensory experience must include __________.
an attribution of intentional content to that experience.
Impure representationalists may allow _____________ into their fundamental account of sensory experience.
non-content elements
Supervenience Claim
Claim that there can be no difference between sensory experiences (in the same sense modality) without a difference in their representational contents.
