4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / h. System S5
S5 collapses iterated modalities (◊□P→□P, and ◊◊P→◊P) [Keefe/Smith]
7. Existence / A. Nature of Existence / 3. Being / d. Non-being
Not-Being obviously doesn't exist, and the five modes of Being are all impossible [Gorgias, by Diog. Laertius]
7. Existence / D. Theories of Reality / 10. Vagueness / b. Vagueness of reality
Objects such as a cloud or Mount Everest seem to have fuzzy boundaries in nature [Keefe/Smith]
7. Existence / D. Theories of Reality / 10. Vagueness / c. Vagueness as ignorance
If someone is borderline tall, no further information is likely to resolve the question [Keefe/Smith]
The simplest approach, that vagueness is just ignorance, retains classical logic and semantics [Keefe/Smith]
The epistemic view of vagueness must explain why we don't know the predicate boundary [Keefe/Smith]
7. Existence / D. Theories of Reality / 10. Vagueness / f. Supervaluation for vagueness
Supervaluationism keeps true-or-false where precision can be produced, but not otherwise [Keefe/Smith]
Vague statements lack truth value if attempts to make them precise fail [Keefe/Smith]
Some of the principles of classical logic still fail with supervaluationism [Keefe/Smith]
The semantics of supervaluation (e.g. disjunction and quantification) is not classical [Keefe/Smith]
Supervaluation misunderstands vagueness, treating it as a failure to make things precise [Keefe/Smith]
7. Existence / D. Theories of Reality / 10. Vagueness / g. Degrees of vagueness
A third truth-value at borderlines might be 'indeterminate', or a value somewhere between 0 and 1 [Keefe/Smith]
People can't be placed in a precise order according to how 'nice' they are [Keefe/Smith]
If truth-values for vagueness range from 0 to 1, there must be someone who is 'completely tall' [Keefe/Smith]
How do we decide if my coat is red to degree 0.322 or 0.321? [Keefe/Smith]
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
We can bring dispositions into existence, as in creating an identifier [Dennett, by Mumford]
9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
Vague predicates involve uncertain properties, uncertain objects, and paradoxes of gradual change [Keefe/Smith]
Many vague predicates are multi-dimensional; 'big' involves height and volume; heaps include arrangement [Keefe/Smith]
If there is a precise borderline area, that is not a case of vagueness [Keefe/Smith]
9. Objects / D. Essence of Objects / 13. Nominal Essence
Words are fixed by being attached to similarity clusters, without mention of 'essences' [Dennett]
12. Knowledge Sources / B. Perception / 2. Qualities in Perception / b. Primary/secondary
Light wavelengths entering the eye are only indirectly related to object colours [Dennett]
14. Science / C. Induction / 1. Induction
Brains are essentially anticipation machines [Dennett]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / a. Consciousness
We can't draw a clear line between conscious and unconscious [Dennett]
Perhaps the brain doesn't 'fill in' gaps in consciousness if no one is looking. [Dennett]
15. Nature of Minds / B. Features of Minds / 1. Consciousness / e. Cause of consciousness
Conscious events can only be explained in terms of unconscious events [Dennett]
15. Nature of Minds / B. Features of Minds / 3. Privacy
We can know a lot of what it is like to be a bat, and nothing important is unknown [Dennett]
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
"Qualia" can be replaced by complex dispositional brain states [Dennett]
15. Nature of Minds / B. Features of Minds / 6. Inverted Qualia
We can't assume that dispositions will remain normal when qualia have been inverted [Dennett]
15. Nature of Minds / B. Features of Minds / 7. Blindsight
In peripheral vision we see objects without their details, so blindsight is not that special [Dennett]
Blindsight subjects glean very paltry information [Dennett]
16. Persons / B. Nature of the Self / 4. Presupposition of Self
People accept blurred boundaries in many things, but insist self is All or Nothing [Dennett]
16. Persons / B. Nature of the Self / 7. Self and Body / c. Self as brain controller
The psychological self is an abstraction, not a thing in the brain [Dennett]
16. Persons / E. Rejecting the Self / 2. Self as Social Construct
Selves are not soul-pearls, but artefacts of social processes [Dennett]
16. Persons / E. Rejecting the Self / 3. Narrative Self
We tell stories about ourselves, to protect, control and define who we are [Dennett]
We spin narratives about ourselves, and the audience posits a centre of gravity for them [Dennett]
16. Persons / E. Rejecting the Self / 4. Denial of the Self
The brain is controlled by shifting coalitions, guided by good purposeful habits [Dennett]
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
If an epiphenomenon has no physical effects, it has to be undetectable [Dennett]
17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique
Dualism wallows in mystery, and to accept it is to give up [Dennett]
17. Mind and Body / C. Functionalism / 6. Homuncular Functionalism
All functionalism is 'homuncular', of one grain size or another [Dennett]
17. Mind and Body / E. Mind as Physical / 3. Eliminativism
It is arbitrary to say which moment of brain processing is conscious [Dennett]
Visual experience is composed of neural activity, which we find pleasing [Dennett]
19. Language / F. Communication / 1. Rhetoric
Gorgias says rhetoric is the best of arts, because it enslaves without using force [Gorgias, by Plato]
Destroy seriousness with laughter, and laughter with seriousness [Gorgias]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
Originally there were no reasons, purposes or functions; since there were no interests, there were only causes [Dennett]
