9154 | Frege agreed with Euclid that the axioms of logic and mathematics are known through self-evidence [Frege, by Burge] |
9157 | The null set is only defensible if it is the extension of an empty concept [Frege, by Burge] |

14150 | Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato] |
8640 | We cannot define numbers from the idea of a series, because numbers must precede that [Frege] |
9838 | Treating 0 as a number avoids antinomies involving treating 'nobody' as a person [Frege, by Dummett] |
9564 | For Frege 'concept' and 'extension' are primitive, but 'zero' and 'successor' are defined [Frege, by Chihara] |
10551 | If objects exist because they fall under a concept, 0 is the object under which no objects fall [Frege, by Dummett] |
8653 | Nought is the number belonging to the concept 'not identical with itself' [Frege] |

17429 | Frege says only concepts which isolate and avoid arbitrary division can give units [Frege, by Koslicki] |
17427 | Frege's 'isolation' could be absence of overlap, or drawing conceptual boundaries [Frege, by Koslicki] |
17437 | Non-arbitrary division means that what falls under the concept cannot be divided into more of the same [Frege, by Koslicki] |
17438 | Our concepts decide what is countable, as in seeing the leaves of the tree, or the foliage [Frege, by Koslicki] |

13871 | Frege claims that numbers are objects, as opposed to them being Fregean concepts [Frege, by Wright,C] |
13872 | Numbers are second-level, ascribing properties to concepts rather than to objects [Frege, by Wright,C] |
9816 | For Frege, successor was a relation, not a function [Frege, by Dummett] |
9953 | Numbers are more than just 'second-level concepts', since existence is also one [Frege, by George/Velleman] |

10139 | Frege gives an incoherent account of extensions resulting from abstraction [Fine,K on Frege] |
10028 | For Frege the number of F's is a collection of first-level concepts [Frege, by George/Velleman] |
17636 | A cardinal number may be defined as a class of similar classes [Frege, by Russell] |
10029 | Numbers need to be objects, to define the extension of the concept of each successor to n [Frege, by George/Velleman] |

9856 | Frege's account of cardinals fails in modern set theory, so they are now defined differently [Dummett on Frege] |
9902 | Frege's incorrect view is that a number is an equivalence class [Benacerraf on Frege] |
17814 | The natural number n is the set of n-membered sets [Frege, by Yourgrau] |
17819 | A set doesn't have a fixed number, because the elements can be seen in different ways [Yourgrau on Frege] |
17820 | If you can subdivide objects many ways for counting, you can do that to set-elements too [Yourgrau on Frege] |
9956 | 'The number of Fs' is the extension (a collection of first-level concepts) of the concept 'equinumerous with F' [Frege, by George/Velleman] |

17442 | Frege thinks number is fundamentally bound up with one-one correspondence [Frege, by Heck] |
11030 | The words 'There are exactly Julius Caesar moons of Mars' are gibberish [Rumfitt on Frege] |
10030 | 'Julius Caesar' isn't a number because numbers inherit properties of 0 and successor [Frege, by George/Velleman] |
8690 | From within logic, how can we tell whether an arbitrary object like Julius Caesar is a number? [Frege, by Friend] |
10219 | Frege said 2 is the extension of all pairs (so Julius Caesar isn't 2, because he's not an extension) [Frege, by Shapiro] |
13889 | Fregean numbers are numbers, and not 'Caesar', because they correlate 1-1 [Frege, by Wright,C] |
18142 | One-one correlations imply normal arithmetic, but don't explain our concept of a number [Frege, by Bostock] |
9046 | Our definition will not tell us whether or not Julius Caesar is a number [Frege] |
16896 | If numbers can be derived from logic, then set theory is superfluous [Frege, by Burge] |
8639 | If numbers are supposed to be patterns, each number can have many patterns [Frege] |
16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato] |
13874 | Numbers seem to be objects because they exactly fit the inference patterns for identities [Frege] |
13875 | Frege's platonism proposes that objects are what singular terms refer to [Frege, by Wright,C] |
7731 | How can numbers be external (one pair of boots is two boots), or subjective (and so relative)? [Frege, by Weiner] |
7737 | Identities refer to objects, so numbers must be objects [Frege, by Weiner] |
8635 | Numbers are not physical, and not ideas - they are objective and non-sensible [Frege] |
8652 | Numbers are objects, because they can take the definite article, and can't be plurals [Frege] |
17816 | Frege's logicism aimed at removing the reliance of arithmetic on intuition [Frege, by Yourgrau] |
8633 | There is no physical difference between two boots and one pair of boots [Frege] |
9951 | It appears that numbers are adjectives, but they don't apply to a single object [Frege, by George/Velleman] |
9952 | Numerical adjectives are of the same second-level type as the existential quantifier [Frege, by George/Velleman] |
11031 | 'Jupiter has many moons' won't read as 'The number of Jupiter's moons equals the number many' [Rumfitt on Frege] |
8637 | The number 'one' can't be a property, if any object can be viewed as one or not one [Frege] |
9999 | For science, we can translate adjectival numbers into noun form [Frege] |
7739 | Arithmetic is analytic [Frege, by Weiner] |
9945 | Logicism shows that no empirical truths are needed to justify arithmetic [Frege, by George/Velleman] |
8782 | Frege offered a Platonist version of logicism, committed to cardinal and real numbers [Frege, by Hale/Wright] |
13608 | Mathematics has no special axioms of its own, but follows from principles of logic (with definitions) [Frege, by Bostock] |
16905 | Arithmetic must be based on logic, because of its total generality [Frege, by Jeshion] |
5658 | Numbers are definable in terms of mapping items which fall under concepts [Frege, by Scruton] |
8655 | Arithmetic is analytic and a priori, and thus it is part of logic [Frege] |
10831 | Frege only managed to prove that arithmetic was analytic with a logic that included set-theory [Quine on Frege] |
13864 | Frege's platonism and logicism are in conflict, if logic must dictates an infinity of objects [Wright,C on Frege] |
10033 | Why should the existence of pure logic entail the existence of objects? [George/Velleman on Frege] |
10010 | Frege's belief in logicism and in numerical objects seem uncomfortable together [Hodes on Frege] |
9631 | Formalism fails to recognise types of symbols, and also meta-games [Frege, by Brown,JR] |
9875 | Frege was completing Bolzano's work, of expelling intuition from number theory and analysis [Frege, by Dummett] |
8642 | Abstraction from things produces concepts, and numbers are in the concepts [Frege] |
8621 | Mental states are irrelevant to mathematics, because they are vague and fluctuating [Frege] |
8643 | Affirmation of existence is just denial of zero [Frege] |
229 | The one was and is and will be and was becoming and is becoming and will become [Plato] |
21821 | Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus] |
8911 | If abstracta are non-mental, quarks are abstracta, and yet chess and God's thoughts are mental [Rosen on Frege] |
8634 | The equator is imaginary, but not fictitious; thought is needed to recognise it [Frege] |
14942 | Only admit into ontology what is explanatory and predictive [Ladyman/Ross] |
14948 | To be is to be a real pattern [Ladyman/Ross] |
14947 | Any process can be described as transfer of measurable information [Ladyman/Ross] |
17443 | Many of us find Frege's claim that truths depend on one another an obscure idea [Heck on Frege] |
17445 | Parallelism is intuitive, so it is more fundamental than sameness of direction [Frege, by Heck] |
14941 | We say there is no fundamental level to ontology, and reality is just patterns [Ladyman/Ross] |
10539 | Frege refers to 'concrete' objects, but they are no different in principle from abstract ones [Frege, by Dummett] |
10493 | If concrete is spatio-temporal and causal, and abstract isn't, the distinction doesn't suit physics [Ladyman/Ross] |
14934 | Concrete and abstract are too crude for modern physics [Ladyman/Ross] |
221 | Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato] |
14909 | Physicalism is 'part-whole' (all parts are physical), or 'supervenience/levels' (dependence on physical) [Ladyman/Ross] |
17431 | Vagueness is incomplete definition [Frege, by Koslicki] |
13879 | For Frege, ontological questions are to be settled by reference to syntactic structures [Frege, by Wright,C] |
10642 | Second-order quantifiers are committed to concepts, as first-order commits to objects [Frege, by Linnebo] |
14926 | Relations without relata must be treated as universals, with their own formal properties [Ladyman/Ross] |
14929 | A belief in relations must be a belief in things that are related [Ladyman/Ross] |
14925 | The normal assumption is that relations depend on properties of the relata [Ladyman/Ross] |
14931 | That there are existent structures not made of entities is no stranger than the theory of universals [Ladyman/Ross] |
10032 | 'Ancestral' relations are derived by iterating back from a given relation [Frege, by George/Velleman] |
10606 | Frege treats properties as a kind of function, and maybe a property is its characteristic function [Frege, by Smith,P] |
14932 | Causal essentialism says properties are nothing but causal relations [Ladyman/Ross] |
14920 | If science captures the modal structure of things, that explains why its predictions work [Ladyman/Ross] |
223 | If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato] |
227 | You must always mean the same thing when you utter the same name [Plato] |
210 | It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato] |
220 | The concept of a master includes the concept of a slave [Plato] |
211 | If admirable things have Forms, maybe everything else does as well [Plato] |
219 | If absolute ideas existed in us, they would cease to be absolute [Plato] |
228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato] |
16151 | Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M] |
218 | Participation is not by means of similarity, so we are looking for some other method of participation [Plato] |
215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato] |
216 | If things are made alike by participating in something, that thing will be the absolute idea [Plato] |
217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |
214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato] |
14952 | Things are constructs for tracking patterns (and not linguistic, because animals do it) [Ladyman/Ross] |
8647 | Not all objects are spatial; 4 can still be an object, despite lacking spatial co-ordinates [Frege] |
10309 | Frege says singular terms denote objects, numerals are singular terms, so numbers exist [Frege, by Hale] |
10550 | Frege establishes abstract objects independently from concrete ones, by falling under a concept [Frege, by Dummett] |
8785 | For Frege, objects just are what singular terms refer to [Frege, by Hale/Wright] |
10278 | Without concepts we would not have any objects [Frege, by Shapiro] |
17432 | Frege's universe comes already divided into objects [Frege, by Koslicki] |
14950 | Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross] |
14927 | Physics seems to imply that we must give up self-subsistent individuals [Ladyman/Ross] |
14944 | There is no single view of individuals, because different sciences operate on different scales [Ladyman/Ross] |
14946 | There are no cats in quantum theory, and no mountains in astrophysics [Ladyman/Ross] |
15851 | Parts must belong to a created thing with a distinct form [Plato] |
14928 | Things are abstractions from structures [Ladyman/Ross] |
14892 | The idea of composition, that parts of the world are 'made of' something, is no longer helpful [Ladyman/Ross] |
15846 | In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V] |
15849 | Plato says only a one has parts, and a many does not [Plato, by Harte,V] |
15850 | Anything which has parts must be one thing, and parts are of a one, not of a many [Plato] |
13259 | It seems that the One must be composed of parts, which contradicts its being one [Plato] |
14949 | A sum of things is not a whole if the whole does not support some new generalisation [Ladyman/Ross] |
14951 | We treat the core of a pattern as an essence, in order to keep track of it [Ladyman/Ross] |

11100 | Frege's algorithm of identity is the law of putting equals for equals [Frege, by Quine] |
12153 | Geach denies Frege's view, that 'being the same F' splits into being the same and being F [Perry on Frege] |
15847 | Two things relate either as same or different, or part of a whole, or the whole of the part [Plato] |
9853 | Identity between objects is not a consequence of identity, but part of what 'identity' means [Frege, by Dummett] |
14903 | Quantum mechanics seems to imply single-case probabilities [Ladyman/Ross] |
14923 | In quantum statistics, two separate classical states of affairs are treated as one [Ladyman/Ross] |
17623 | To understand a thought you must understand its logical structure [Frege, by Burge] |
9158 | For Frege a priori knowledge derives from general principles, so numbers can't be primitive [Frege] |
8657 | Mathematicians just accept self-evidence, whether it is logical or intuitive [Frege] |
9352 | An a priori truth is one derived from general laws which do not require proof [Frege] |
16889 | A truth is a priori if it can be proved entirely from general unproven laws [Frege] |
2514 | Frege tried to explain synthetic a priori truths by expanding the concept of analyticity [Frege, by Katz] |
14955 | Rats find some obvious associations easier to learn than less obvious ones [Ladyman/Ross] |
14918 | The doctrine of empiricism does not itself seem to be empirically justified [Ladyman/Ross] |
16900 | Intuitions cannot be communicated [Frege, by Burge] |
14891 | There is no reason to think our intuitions are good for science or metaphysics [Ladyman/Ross] |
16903 | Justifications show the ordering of truths, and the foundation is what is self-evident [Frege, by Jeshion] |
14915 | The theory of evolution was accepted because it explained, not because of its predictions [Ladyman/Ross] |
14916 | What matters is whether a theory can predict - not whether it actually does so [Ladyman/Ross] |
14922 | The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross] |
14921 | The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross] |
8624 | Induction is merely psychological, with a principle that it can actually establish laws [Frege] |
8626 | In science one observation can create high probability, while a thousand might prove nothing [Frege] |
14953 | Induction is reasoning from the observed to the unobserved [Ladyman/Ross] |
14914 | Inductive defences of induction may be rule-circular, but not viciously premise-circular [Ladyman/Ross] |
14913 | We explain by deriving the properties of a phenomenon by embedding it in a large abstract theory [Ladyman/Ross] |
8648 | Ideas are not spatial, and don't have distances between them [Frege] |
14930 | Maybe the only way we can think about a domain is by dividing it up into objects [Ladyman/Ross] |
14939 | Two versions of quantum theory say that the world is deterministic [Ladyman/Ross] |
14911 | Science is opposed to downward causation [Ladyman/Ross] |
8620 | Thought is the same everywhere, and the laws of thought do not vary [Frege] |
9870 | Early Frege takes the extensions of concepts for granted [Frege, by Dummett] |
13878 | Concepts are, precisely, the references of predicates [Frege, by Wright,C] |
7736 | A concept is a non-psychological one-place function asserting something of an object [Frege, by Weiner] |
17430 | Fregean concepts have precise boundaries and universal applicability [Frege, by Koslicki] |
8622 | Psychological accounts of concepts are subjective, and ultimately destroy truth [Frege] |
8651 | A concept is a possible predicate of a singular judgement [Frege] |
9846 | Defining 'direction' by parallelism doesn't tell you whether direction is a line [Dummett on Frege] |
9976 | Frege accepts abstraction to the concept of all sets equipollent to a given one [Tait on Frege] |
10803 | Frege himself abstracts away from tone and color [Yablo on Frege] |
9988 | If we abstract 'from' two cats, the units are not black or white, or cats [Tait on Frege] |
9855 | Frege's logical abstaction identifies a common feature as the maximal set of equivalent objects [Frege, by Dummett] |
10802 | Frege's 'parallel' and 'direction' don't have the same content, as we grasp 'parallel' first [Yablo on Frege] |
10525 | Frege put the idea of abstraction on a rigorous footing [Frege, by Fine,K] |
10526 | Fregean abstraction creates concepts which are equivalences between initial items [Frege, by Fine,K] |
10556 | We create new abstract concepts by carving up the content in a different way [Frege] |
9882 | You can't simultaneously fix the truth-conditions of a sentence and the domain of its variables [Dummett on Frege] |
9881 | From basing 'parallel' on identity of direction, Frege got all abstractions from identity statements [Frege, by Dummett] |
8646 | Words in isolation seem to have ideas as meanings, but words have meaning in propositions [Frege] |
7732 | Never ask for the meaning of a word in isolation, but only in the context of a proposition [Frege] |
9370 | A statement is analytic if substitution of synonyms can make it a logical truth [Frege, by Boghossian] |
8743 | Frege considered analyticity to be an epistemic concept [Frege, by Shapiro] |
20295 | All analytic truths can become logical truths, by substituting definitions or synonyms [Frege, by Rey] |
2515 | Frege fails to give a concept of analyticity, so he fails to explain synthetic a priori truth that way [Katz on Frege] |
8619 | To learn something, you must know that you don't know [Frege] |
222 | Only a great person can understand the essence of things, and an even greater person can teach it [Plato] |
225 | The unlimited has no shape and is endless [Plato] |
233 | Some things do not partake of the One [Plato] |
2062 | The only movement possible for the One is in space or in alteration [Plato] |
231 | Everything partakes of the One in some way [Plato] |
14956 | Explanation by kinds and by clusters of properties just express the stability of reality [Ladyman/Ross] |
14957 | There is nothing more to a natural kind than a real pattern in nature [Ladyman/Ross] |
14954 | Causation is found in the special sciences, but may have no role in fundamental physics [Ladyman/Ross] |
14902 | Science may have uninstantiated laws, inferred from approaching some unrealised limit [Ladyman/Ross] |
