17311 | Real definitions don't just single out a thing; they must also explain its essence [Koslicki] |
8729 | Intuitionists deny excluded middle, because it is committed to transcendent truth or objects [Shapiro] |
8763 | The number 3 is presumably identical as a natural, an integer, a rational, a real, and complex [Shapiro] |
18249 | Cauchy gave a formal definition of a converging sequence. [Shapiro] |
8764 | Categories are the best foundation for mathematics [Shapiro] |
17312 | It is more explanatory if you show how a number is constructed from basic entities and relations [Koslicki] |
8762 | Two definitions of 3 in terms of sets disagree over whether 1 is a member of 3 [Shapiro] |
8760 | Numbers do not exist independently; the essence of a number is its relations to other numbers [Shapiro] |
8761 | A 'system' is related objects; a 'pattern' or 'structure' abstracts the pure relations from them [Shapiro] |
8744 | Logicism seems to be a non-starter if (as is widely held) logic has no ontology of its own [Shapiro] |
8749 | Term Formalism says mathematics is just about symbols - but real numbers have no names [Shapiro] |
8750 | Game Formalism is just a matter of rules, like chess - but then why is it useful in science? [Shapiro] |
8752 | Deductivism says mathematics is logical consequences of uninterpreted axioms [Shapiro] |
8753 | Critics resent the way intuitionism cripples mathematics, but it allows new important distinctions [Shapiro] |

17309 | For Fine, essences are propositions true because of identity, so they are just real definitions [Koslicki] |
17315 | We need a less propositional view of essence, and so must distinguish it clearly from real definitions [Koslicki] |
8725 | Rationalism tries to apply mathematical methodology to all of knowledge [Shapiro] |
17317 | A good explanation captures the real-world dependence among the phenomena [Koslicki] |
17316 | We can abstract to a dependent entity by blocking out features of its bearer [Koslicki] |
