|
Philosophers of logic and maths insisted that a vocabulary of relations was essential [Russell, by Heil]
|
21534
|
The only thing we can say about relations is that they relate [Russell]
|
21540
|
Relational propositions seem to be 'about' their terms, rather than about the relation [Russell]
|
21562
|
There is no complexity without relations, so no propositions, and no truth [Russell]
|
5371
|
Because we depend on correspondence, we know relations better than we know the items that relate [Russell]
|
5407
|
That Edinburgh is north of London is a non-mental fact, so relations are independent universals [Russell]
|
21576
|
With asymmetrical relations (before/after) the reduction to properties is impossible [Russell]
|
8. Modes of Existence / A. Relations / 4. Formal Relations / a. Types of relation
14430
|
If a relation is symmetrical and transitive, it has to be reflexive [Russell]
|
10586
|
'Reflexiveness' holds between a term and itself, and cannot be inferred from symmetry and transitiveness [Russell]
|
14432
|
'Asymmetry' is incompatible with its converse; a is husband of b, so b can't be husband of a [Russell]
|
8. Modes of Existence / A. Relations / 4. Formal Relations / b. Equivalence relation
10585
|
Symmetrical and transitive relations are formally like equality [Russell]
|
8. Modes of Existence / B. Properties / 11. Properties as Sets
9127

Russell refuted Frege's principle that there is a set for each property [Russell, by Sorensen]
|
21575
|
When we attribute a common quality to a group, we can forget the quality and just talk of the group [Russell]
|
8. Modes of Existence / B. Properties / 12. Denial of Properties
6063
|
Russell can't attribute existence to properties [McGinn on Russell]
|
8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes
14327
|
Trope theorists cannot explain how tropes resemble each other [Russell, by Mumford]
|
8. Modes of Existence / D. Universals / 1. Universals
5383
|
Every complete sentence must contain at least one word (a verb) which stands for a universal [Russell]
|
4428
|
Propositions express relations (prepositions and verbs) as well as properties (nouns and adjectives) [Russell]
|
5406
|
Confused views of reality result from thinking that only nouns and adjectives represent universals [Russell]
|
4479
|
All universals are like the relation "is north of", in having no physical location at all [Russell, by Loux]
|
8. Modes of Existence / D. Universals / 2. Need for Universals
21710
|
We know a universal in 'yellow differs from blue' or 'yellow resembles blue less than green does' [Russell]
|
4030
|
Russell claims that universals are needed to explain a priori knowledge (as their relations) [Russell, by Mellor/Oliver]
|
4427
|
Every sentence contains at least one word denoting a universal, so we need universals to know truth [Russell]
|
8. Modes of Existence / D. Universals / 4. Uninstantiated Universals
5409
|
Normal existence is in time, so we must say that universals 'subsist' [Russell]
|
8. Modes of Existence / D. Universals / 5. Universals as Concepts
5408
|
If we identify whiteness with a thought, we can never think of it twice; whiteness is the object of a thought [Russell]
|
8. Modes of Existence / E. Nominalism / 2. Resemblance Nominalism
4441
|
'Resemblance Nominalism' won't work, because the theory treats resemblance itself as a universal [Russell]
|
8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism
6440
|
Universals can't just be words, because words themselves are universals [Russell]
|
8. Modes of Existence / E. Nominalism / 4. Concept Nominalism
4429
|
If we consider whiteness to be merely a mental 'idea', we rob it of its universality [Russell]
