1. Philosophy / E. Nature of Metaphysics / 1. Nature of Metaphysics
18859 Metaphysics is a quest for truthmakers [Tallant]
2. Reason / D. Definition / 12. Paraphrase
18861 Maybe number statements can be paraphrased into quantifications plus identities [Tallant]
3. Truth / B. Truthmakers / 3. Truthmaker Maximalism
18866 Maybe only 'positive' truths need truth-makers [Tallant]
3. Truth / B. Truthmakers / 5. What Makes Truths / a. What makes truths
18860 A truthmaker is the minimal portion of reality that will do the job [Tallant]
3. Truth / B. Truthmakers / 12. Rejecting Truthmakers
18863 What is the truthmaker for a possible new power? [Tallant]
4. Formal Logic / E. Nonclassical Logics / 8. Intensional Logic
15375 If terms change their designations in different states, they are functions from states to objects [Fitting]
15376 Intensional logic adds a second type of quantification, over intensional objects, or individual concepts [Fitting]
4. Formal Logic / E. Nonclassical Logics / 9. Awareness Logic
15378 Awareness logic adds the restriction of an awareness function to epistemic logic [Fitting]
4. Formal Logic / E. Nonclassical Logics / 10. Justification Logics
15379 Justication logics make explicit the reasons for mathematical truth in proofs [Fitting]
5. Theory of Logic / A. Overview of Logic / 8. Logic of Mathematics
11026 Classical logic is deliberately extensional, in order to model mathematics [Fitting]
5. Theory of Logic / F. Referring in Logic / 3. Property (λ-) Abstraction
11028 λ-abstraction disambiguates the scope of modal operators [Fitting]
7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
17486 Supervenience is simply modally robust property co-variance [Hendry]
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
18864 The wisdom of Plato and of Socrates are not the same property [Tallant]
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
18865 Substance must have two properties: individuation, and property-bearing [Tallant]
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
15377 Definite descriptions pick out different objects in different possible worlds [Fitting]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
17481 Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry]
19. Language / D. Propositions / 2. Abstract Propositions / a. Propositions as sense
18862 Are propositions all the thoughts and sentences that are possible? [Tallant]
26. Natural Theory / B. Natural Kinds / 2. Defining Kinds
17478 Maybe two kinds are the same if there is no change of entropy on isothermal mixing [Hendry]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / a. Scientific essentialism
17484 Maybe the nature of water is macroscopic, and not in the microstructure [Hendry]
17479 The nature of an element must survive chemical change, so it is the nucleus, not the electrons [Hendry]
17485 Maybe water is the smallest part of it that still counts as water (which is H2O molecules) [Hendry]
27. Natural Reality / F. Chemistry / 1. Chemistry
17482 Compounds can differ with the same collection of atoms, so structure matters too [Hendry]
17483 Water continuously changes, with new groupings of molecules [Hendry]
27. Natural Reality / F. Chemistry / 2. Modern Elements
17476 Elements survive chemical change, and are tracked to explain direction and properties [Hendry]
17477 Defining elements by atomic number allowed atoms of an element to have different masses [Hendry]
27. Natural Reality / F. Chemistry / 3. Periodic Table
17480 Generally it is nuclear charge (not nuclear mass) which determines behaviour [Hendry]
