1
Q

What are the two types of identity searched for in personal identity?

Q

Why does the memory criterion beg the question?

A

Given that memories are only genuine you really are the person remembering them, then evidently memories show nothing

Q

What is the solution to the fission problem?

A

Multiple-occupancy view (Robinson) that both halves are seen as separate in any case, or say that fission is death of individual and birth of two new ones (given special relationship when two halves are together)

Q

Why is the mind, or consciousness, believed to be a good differentiator of individuals in terms of extended space?

A

Whilst the brain may have the same configuration of atoms, there would be different thoughts and memories held by the person - we own and input our own thoughts

Why does Olson not believe in thoughts as key?

Q

How does externalism overcome scepticism?

A

Q

How does learning ruin contextualism?

A

Learning can lead to increased doubt for Williamson, yet there is no change of context - depends on definition of context

56
Q

What weird normative principles does contextualism cause?

A

If you really had less knowledge in a seminar, you would not want to leave it? Sense of superiority gained from scepticism only (Williamson)

57
Q

What are two problems for Moore?

A

Claims general and philosophical in nature need to be answered by Moore (Nagel). Also rationality does not always equate to simplicity, ie detective case

58
Q

What is Moore’s approach?

A

I have hands, hands are external objects, therefore external objects exist due to epistemic closure principle This offers conclusive evidence for claims of knowledge, rather than proof

59
Q

What is the classic response to Moore?

A

It begs the question as I have hands is a questionable conclusion - yet apparently we are meant to trust commonsense

60
Q

What is Russell’s response to scepticism?

A

Interference to the Best Explanation - logically possible for sceptical scenario, yet we should always opt for best solution when all else is equal - belief in knowledge is simplest way to take our life experiences

61
Q

What is the response to Russell?

A

Reasonable and simple is not always correct. Also, a supercomputer is a simpler explanation of life

62
Q

What is the overall conclusion of contextualism?

A

We have lots of everyday knowledge in ordinary contexts, even if we cannot meet high sceptical claims

63
Q

What is the fundamental flaw of contextualism?

A

There is still no way we can know that we are not in a sceptical scenario, regardless of context

64
Q

How does Williamson view a change in contexts?

A

It just causes us to question if we have enough evidence to reach an original existing standard for knowledge, rather than increasing epistemic standards

65
Q

How does Putnam refute scepticism and brains in vats?

A

Since you cannot refer to something physical in the world beyond the simulation, as there is no way of achieving knowledge in that area due to semantic externalism, there is knowledge available

66
Q

How does Chalmers view the matrix?

A

Thoughts and beliefs refer to something computational rather than physical objects. This is akin to learning of string theory - it damages our idea of matter, but should not affect our knowledge claims too much ie requiring to refer to objects in new ways

67
Q

How does Chalmers view his theory?

A

A metaphysical argument that the physical world made from a computer is a real one

68
Q

How does Chalmers understand knowledge claims?

A

The process that our minds are connected to, by motor inputs and outputs are key - mind over reality is key for knowledge, so start every word with virtual

69
Q

How does Chalmers use science in his argument?

A

There is no precision in knowledge claims in matrix, much like there is no precise quantum wave function

70
Q

How does Pritchard use science to come to his argument?

A

Science has shown us that nothing is truly flat or empty, so there are never any knowledge claims

71
Q

How does DeRose criticise Lewis?

A

Rule of Accommodation does not differ for strong or poor argumentation, which could alter contexts

72
Q

How does DeRose compare contexts to find knowledge claims?

A

To find if something was non-accidentally true, or sensitive to the world, then use nearby worlds to see if the same holds - brain in vat world is a very distant world

73
Q

How does DeRose deride the sceptic?

A

Not-P worlds are quite distant, and if you enlarge the sphere of epistemically relevant worlds which include the nearest false one, then there would be a very large circle and therefore the sceptical scenario requires too high epistemic standards

74
Q

How does DeRose describe the standards of the sceptic?

A

Unusually inflated standards

75
Q

How does Putnam show the grounding problem of scepticism?

A

There is no connection between representation and what something represents ie snail in sand or brain in vat

76
Q

How does Putnam overcome the brain in the vat?

A

We cannot refer to brains in vats, as we have to have some kind of causal connection between an object and our reference to it. There is a causal constraint to our reference of a BIV therefore

77
Q

How does Williamson use probability?

A

Given that the probability of sceptical scenarios do not decrease when we do not know about them, no reason for contextualism

78
Q

How does Williamson use the verb ‘know’ to disown contextualism?

A

He views it as a factive verb with no context dependence

79
Q

How does Williamson use the seminar room to rebute contextualism?

A

Within the seminar room individuals express truths that are relevant outside of the seminar, so there are no real contexts, with some contexts spilling into another

80
Q

How does Williamson show the pointlessness of contexts?

A

Third and first person context changes do not change knowledge - situation is still materially the same

81
Q

How does Unger create a sceptical idea?

A

To know something, a person must be absolutely certain, something with rarely arises as certainty is an absolute term - there is never anything of which he is more certain

82
Q

What does Unger think of contextualists?

A

They take everyday conversation as knowledge, even when one isn’t certain

83
Q

How does Schiffer address the contextualist?

A

When know is a fluid verb as contextualists believe, there will be confusion as individual may think lower epistemic standards in play and incorrectly believe someone

84
Q

Why does Lewis decide to find a contextualist solution?

A

A certain amount is presupposed in any conversation

85
Q

What does Lewis believe about Unger’s argument?

A

There is no reason for a higher epistemic standard rather than a lower one being more legitimate

86
Q

How does Lewis defend the uneducated?

A

In their original contexts, the statements are true - but true to who?

87
Q

What does Dretske believe?

A

Be pragmatic and practical with knowledge, not absolutes but instead shifting relevancy sets to what truly is knowledge

88
Q

What does exists simpliciter mean?

A

All that exists ie presentism as present as what exists simpliciter, with that changing from moment to moment

89
Q

What are the theses used in presentism?

A

Ontological thesis (restricted to current moment) and dynamical thesis (that the present moves)

90
Q

How does the eternalist describe now, the current moment?

A

An indexical notion, simply simultaneous with your current being - the future is to exist later, the past is to exist earlier - all in a relative sense

91
Q

How does the eternalist describe the present?

A

Only that which happens to be nearby

92
Q

What is the answer to the book thought experiment?

A

Question of what is present is trivial, as the present is only present relative to itself, with nothing that special about it

93
Q

What is the problem for the eternalist with the flow of time?

A

Prior - there is an idea of waiting for an event before it happens, then experiencing in the present, then reflecting on it as a past experience - the temporal flow shown here is us passing into and out of progressive presents

94
Q

How could the flow of time argument be answered?

A

By showing how the use of all tenses, past present and future, reveals the existence of these planes ie being able to reflect on the past only occurs because of it’s existence, or not being able to wait for the thing in the future that you know will happen in some way

95
Q

What is the asymmetrical problem for eternalism?

A

Presentism can accommodate the idea of a fixed past and an open future, rather than a real and fixed future

96
Q

What the truthmaker idea?

A

An ontological commitment to something exist - if p is true, then there has to be something that makes p true - problem for presentist brought up by Armstrong

97
Q

How can the presentist remove avoid the truthmaker problem entirely?

A

Denying the importance of truthmakers, as they cannot make a proposition true potentially. Also, how about negative truths such as there are no unicorns?

98
Q

How is the truthmaker problem overcome in a more head on way?

A

Bigelow - the past is not lost given the limited number of particles in the world, and these are the truthmaker. The world will always be one with the property of having once been thus and so

99
Q

How can presentism overcome the truthmaker problem with other theories?

A

Determinism, showing that the past and future is grounded by the laws of nature

100
Q

What is the overall problem for the presentist when it comes to truthmaking?

A

The existence of material objects in the present is very different to the existence or truthmaker of past objects

101
Q

What classic idea ruins presentism?

A

Time travel

102
Q

What is the twins paradox?

A

If time is based on mass and speed, then twins in different locations may have time passing at different rates ie in space or earth - present is therefore a reference frame

103
Q

What view on time does Cameron support?

A

Moving spotlight theory - mix of eternalism with idea of special present, denies relative idea of present

104
Q

What view do Casati and Torrengo support?

A

Shrinking-block view of future existing but past not existing

105
Q

What is the view McCall supports?

A

Shrinking-tree idea of past as trunk of tree, present as point of branching and future as the multiple branches that disappear when they are not taken

106
Q

Why did Broad support the growing block view in Scientific Thought?

A

Time not only has an intrinsic order but an intrinsic sense, or direction from past to future, rather than in reverse - cannot change direction of events in time

107
Q

Why does Miller disagree with the growing block view?

A

It is impossible to tell the difference between the past and the present as they are seen as just the same thing. Statements affirming the present of now appear false as they fall into the objective past immediately

108
Q

Why does the eternalist avoid the When am I? problem?

A

They see no difference between the past, the present and the future - it is all relative

109
Q

How does Forrest overcome problems for the growing block theory?

A

Life and sentience are activities, not states, that only occur the boundary of reality rather than states in the past - yet state of shock?

110
Q

What is the problem for Forrest?

A

The dead past idea - everyone in the past is dead, and there is no life or phenomenology, even if being alive is dependent on having other slices of time that evidently exist in the growing block theory

111
Q

How do Curtis and Robson separate presentism from eternalism?

A

Presentism is a tensed idea, whilst eternalism is tenseless making the whole thing based on semantics

112
Q

What is the singular proposition objection to presentism?

A

When addressing past-tensed sentences directly about some object, you see that object as existing, something the presentist denies

113
Q

What is the cross-temporal relations objection to presentism?

A

Since those in present can have relationships with things in the past, these things must exist ie I like Hume

114
Q

What is the thick and thin objection to presentism?

A

If present is thick then just shorter eternalism. Russell argues that events take time to occur so the present cannot be thin (perhaps everything in a state of doing however)

115
Q

How does Miller deny the growing block theory?

A

Presentists see other hyper-planes than the present as things that did exist and will exist - so just taking past eternalist?

116
Q

What is the reason for things existing for Bigelow?

A

Limited particles and the fact the world itself instantiates the properties of having once contained dinosaurs

117
Q

How does Keller overcome add to Bigelow?

A

Haecceitism - every individual posses an essential property of ‘thisness’, being the thing which it is. If this property is an entity in it’s own right, then it can exist whilst being unsubstantiated ie a megagon

118
Q

What is the benefit of Keller over Bigelow?

A

Events and facts are more fine-grained with multiple haecceities with many things having properties of being

119
Q

How does Keller use atomic particles in his second suggestion?

A

Particles have encoded within them their entire history, including where they have been at different times - therefore there were some arrangements of a particles, particles that still exist in the present, that were objects in the past

120
Q

What is internalism?

A

The idea that the first person perspective of the believer is crucial for belief - only ever justification of a belief if you are aware of a justification through reflection

121
Q

What are the types of justification relevant for the internalist?

A

Things we are aware of - evidence and the reason to trust it. Things we are not aware of are irrelevant such as reliability of cognitive system

122
Q

What is the simplest reason to support internalism?

A

It is intuitive - one can only be justified with the evidence they are aware of and can articulate - justification is tied to the ability to justify therefore

123
Q

Why does responsibility ideas help the internalist?

A

You should do all you can to ensure your belief is true so you can justify it, so ensure belief system is consistent with evidence you hold

124
Q

What is the historical response to internalism?

A

We cannot remember reasons for some beliefs even if we feel they are justified

125
Q

Why do some agents not come up to the standards of internalism?

A
