6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / d. Counting via concepts
Are 'word token' and 'word type' different sorts of countable objects, or two ways of counting? [Geach, by Perry]
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / c. Against mathematical empiricism
Abstraction from objects won't reveal an operation's being performed 'so many times' [Geach]
7. Existence / C. Structure of Existence / 7. Abstract/Concrete / b. Levels of abstraction
We can rise by degrees through abstraction, with higher levels representing more things [Arnauld,A/Nicole,P]
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Attributes are functions, not objects; this distinguishes 'square of 2' from 'double of 2' [Geach]
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
We should abandon absolute identity, confining it to within some category [Geach, by Hawthorne]
9. Objects / F. Identity among Objects / 3. Relative Identity
Denial of absolute identity has drastic implications for logic, semantics and set theory [Wasserman on Geach]
Identity is relative. One must not say things are 'the same', but 'the same A as' [Geach]
9. Objects / F. Identity among Objects / 8. Leibniz's Law
Leibniz's Law is incomplete, since it includes a non-relativized identity predicate [Geach, by Wasserman]
9. Objects / F. Identity among Objects / 9. Sameness
Being 'the same' is meaningless, unless we specify 'the same X' [Geach]
11. Knowledge Aims / A. Knowledge / 4. Belief / a. Beliefs
The goodness of opinions depends on their grounds, and corresponding degrees of conviction [Ross]
11. Knowledge Aims / B. Certain Knowledge / 1. Certainty
Knowledge is superior to opinion because it is certain [Ross]
12. Knowledge Sources / B. Perception / 3. Representation
We can only know the exterior world via our ideas [Arnauld,A/Nicole,P]
12. Knowledge Sources / B. Perception / 7. Causal Perception
I prefer the causal theory to sense data, because sensations are events, not apprehensions [Ross]
14. Science / B. Scientific Theories / 5. Commensurability
Two goods may be comparable, although they are not commensurable [Ross]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Forms make things distinct and explain the properties, by pure form, or arrangement of parts [Arnauld,A/Nicole,P]
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
We know by abstraction because we only understand composite things a part at a time [Arnauld,A/Nicole,P]
A big flea is a small animal, so 'big' and 'small' cannot be acquired by abstraction [Geach]
We cannot learn relations by abstraction, because their converse must be learned too [Geach]
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
A triangle diagram is about all triangles, if some features are ignored [Arnauld,A/Nicole,P]
If concepts are just recognitional, then general judgements would be impossible [Geach]
15. Nature of Minds / C. Capacities of Minds / 6. Idealisation
No one denies that a line has width, but we can just attend to its length [Arnauld,A/Nicole,P]
17. Mind and Body / B. Behaviourism / 2. Potential Behaviour
You can't define real mental states in terms of behaviour that never happens [Geach]
17. Mind and Body / B. Behaviourism / 4. Behaviourism Critique
Beliefs aren't tied to particular behaviours [Geach]
17. Mind and Body / D. Property Dualism / 5. Supervenience of mind
Identical objects must have identical value [Ross]
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
The mind does not lift concepts from experience; it creates them, and then applies them [Geach]
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
For abstractionists, concepts are capacities to recognise recurrent features of the world [Geach]
18. Thought / D. Concepts / 5. Concepts and Language / c. Concepts without language
If someone has aphasia but can still play chess, they clearly have concepts [Geach]
18. Thought / E. Abstraction / 3. Abstracta by Ignoring
'Abstractionism' is acquiring a concept by picking out one experience amongst a group [Geach]
18. Thought / E. Abstraction / 8. Abstractionism Critique
'Or' and 'not' are not to be found in the sensible world, or even in the world of inner experience [Geach]
We can't acquire number-concepts by extracting the number from the things being counted [Geach]
Abstractionists can't explain counting, because it must precede experience of objects [Geach]
The numbers don't exist in nature, so they cannot have been abstracted from there into our languages [Geach]
Blind people can use colour words like 'red' perfectly intelligently [Geach]
If 'black' and 'cat' can be used in the absence of such objects, how can such usage be abstracted? [Geach]
We can form two different abstract concepts that apply to a single unified experience [Geach]
The abstractionist cannot explain 'some' and 'not' [Geach]
Only a judgement can distinguish 'striking' from 'being struck' [Geach]
21. Aesthetics / A. Aesthetic Experience / 2. Aesthetic Attitude
Aesthetic enjoyment combines pleasure with insight [Ross]
21. Aesthetics / A. Aesthetic Experience / 4. Beauty
Beauty is neither objective nor subjective, but a power of producing certain mental events [Ross]
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / e. Ethical cognitivism
Moral duties are as fundamental to the universe as the axioms of mathematics [Ross]
The beauty of a patch of colour might be the most important fact about it [Ross]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / c. Ethical intuitionism
Ross said moral principles are self-evident from the facts, but not from pure thought [Ross, by Dancy,J]
The moral convictions of thoughtful educated people are the raw data of ethics [Ross]
22. Metaethics / B. Value / 1. Nature of Value / a. Nature of value
Value is held to be either a quality, or a relation (usually between a thing and a mind) [Ross]
The arguments for value being an objective or a relation fail, so it appears to be a quality [Ross]
22. Metaethics / B. Value / 1. Nature of Value / c. Objective value
The thing is intrinsically good if it would be good when nothing else existed [Ross]
All things being equal, we all prefer the virtuous to be happy, not the vicious [Ross]
22. Metaethics / B. Value / 1. Nature of Value / e. Means and ends
An instrumentally good thing might stay the same, but change its value because of circumstances [Ross]
22. Metaethics / C. The Good / 1. Goodness / a. Form of the Good
We can ask of pleasure or beauty whether they are valuable, but not of goodness [Ross]
'Good' is an attributive adjective like 'large', not predicative like 'red' [Geach, by Foot]
22. Metaethics / C. The Good / 1. Goodness / b. Types of good
The four goods are: virtue, pleasure, just allocation of pleasure, and knowledge [Ross]
The three intrinsic goods are virtue, knowledge and pleasure [Ross]
22. Metaethics / C. The Good / 1. Goodness / c. Right and good
'Right' and 'good' differ in meaning, as in a 'right action' and a 'good man' [Ross]
If there are two equally good acts, they may both be right, but neither a duty [Ross]
In the past 'right' just meant what is conventionally accepted [Ross]
Goodness is a wider concept than just correct ethical conduct [Ross]
Motives decide whether an action is good, and what is done decides whether it was right [Ross]
22. Metaethics / C. The Good / 1. Goodness / d. Good as virtue
Virtue is superior to pleasure, as pleasure is never a duty, but goodness is [Ross]
22. Metaethics / C. The Good / 1. Goodness / e. Good as knowledge
All other things being equal, a universe with more understanding is better [Ross]
Morality is not entirely social; a good moral character should love truth [Ross]
22. Metaethics / C. The Good / 3. Pleasure / c. Value of pleasure
We clearly value good character or understanding, as well as pleasure [Ross]
No one thinks it doesn't matter whether pleasure is virtuously or viciously acquired [Ross]
23. Ethics / B. Contract Ethics / 3. Promise Keeping
Promise-keeping is bound by the past, and is not concerned with consequences [Ross]
Promises create a new duty to a particular person; they aren't just a strategy to achieve well-being [Ross]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / c. Particularism
Prima facie duties rest self-evidently on particular circumstance [Ross]
23. Ethics / C. Virtue Theory / 3. Virtues / h. Respect
People lose their rights if they do not respect the rights of others [Ross]
23. Ethics / D. Deontological Ethics / 2. Duty
We should do our duty, but not from a sense of duty [Ross]
We like people who act from love, but admire more the people who act from duty [Ross]
Be faithful, grateful, just, beneficent, non-malevolent, and improve yourself [Ross, by PG]
23. Ethics / D. Deontological Ethics / 4. Categorical Imperative
An act may be described in innumerable ways [Ross]
23. Ethics / E. Utilitarianism / 1. Utilitarianism
We should use money to pay debts before giving to charity [Ross]
25. Social Practice / C. Rights / 1. Basis of Rights
Rights were originally legal, and broadened to include other things [Ross]
25. Social Practice / F. Life Issues / 6. Animal Rights
Rights can be justly claimed, so animals have no rights, as they cannot claim any [Ross]
