5. Theory of Logic / L. Paradox / 1. Paradox
6007 If you know your father, but don't recognise your father veiled, you know and don't know the same person [Eubulides, by Dancy,R]
5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / a. The Liar paradox
6006 If you say truly that you are lying, you are lying [Eubulides, by Dancy,R]
5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / b. The Heap paradox ('Sorites')
6008 Removing one grain doesn't destroy a heap, so a heap can't be destroyed [Eubulides, by Dancy,R]
6. Mathematics / A. Nature of Mathematics / 2. Geometry
10245 One geometry cannot be more true than another [Poincaré]
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / d. Actual infinite
15923 Poincaré rejected the actual infinite, claiming definitions gave apparent infinity to finite objects [Poincaré, by Lavine]
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / a. Structuralism
10180 Mathematicians do not study objects, but relations between objects [Poincaré]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / a. Constructivism
9916 Convention, yes! Arbitrary, no! [Poincaré, by Putnam]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / d. Predicativism
18203 Avoid non-predicative classifications and definitions [Poincaré]
7. Existence / E. Categories / 1. Categories
17377 All descriptive language is classificatory [Dupré]
7. Existence / E. Categories / 2. Categorisation
17376 We should aim for a classification which tells us as much as possible about the object [Dupré]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
17390 Natural kinds don't need essentialism to be explanatory [Dupré]
9. Objects / D. Essence of Objects / 10. Essence as Species
17389 A species might have its essential genetic mechanism replaced by a new one [Dupré]
17388 It seems that species lack essential properties, so they can't be natural kinds [Dupré]
14. Science / A. Basis of Science / 4. Prediction
17374 The possibility of prediction rests on determinism [Dupré]
18. Thought / C. Content / 5. Twin Earth
17378 Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
17381 Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré]
17385 Kinds don't do anything (including evolve) because they are abstract [Dupré]
26. Natural Theory / B. Natural Kinds / 7. Critique of Kinds
17375 Natural kinds are decided entirely by the intentions of our classification [Dupré]
17379 Borders between species are much less clear in vegetables than among animals [Dupré]
17384 Even atoms of an element differ, in the energy levels of their electrons [Dupré]
17387 Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré]
17382 Cooks, unlike scientists, distinguish garlic from onions [Dupré]
17380 Wales may count as fish [Dupré]
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
15877 The aim of science is just to create a comprehensive, elegant language to describe brute facts [Poincaré, by Harré]
27. Natural Reality / G. Biology / 5. Species
17383 Species are the lowest-level classification in biology [Dupré]
17386 The theory of evolution is mainly about species [Dupré]
