2. Reason / D. Definition / 1. Definitions
15927 Definition just needs negation, known variables, conjunction, disjunction, substitution and quantification [Weyl, by Lavine]
10. Modality / A. Necessity / 11. Denial of Necessity
20475 Maybe modal sentences cannot be true or false [Casullo]
10. Modality / D. Knowledge of Modality / 1. A Priori Necessary
20476 If the necessary is a priori, so is the contingent, because the same evidence is involved [Casullo]
12. Knowledge Sources / A. A Priori Knowledge / 1. Nature of the A Priori
20471 Epistemic a priori conditions concern either the source, defeasibility or strength [Casullo]
20477 The main claim of defenders of the a priori is that some justifications are non-experiential [Casullo]
12. Knowledge Sources / A. A Priori Knowledge / 4. A Priori as Necessities
20472 Analysis of the a priori by necessity or analyticity addresses the proposition, not the justification [Casullo]
12. Knowledge Sources / A. A Priori Knowledge / 10. A Priori as Subjective
3913 Maybe imagination is the source of a priori justification [Casullo]
13. Knowledge Criteria / A. Justification Problems / 1. Justification / c. Defeasibility
20474 'Overriding' defeaters rule it out, and 'undermining' defeaters weaken in [Casullo]
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
17471 Using mechanisms as explanatory schemes began in chemistry [Weisberg/Needham/Hendry]
17472 Thick mechanisms map whole reactions, and thin mechanism chart the steps [Weisberg/Needham/Hendry]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / f. Ancient elements
17465 Lavoisier's elements included four types of earth [Weisberg/Needham/Hendry]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
10246 The limit of science is isomorphism of theories, with essences a matter of indifference [Weyl]
27. Natural Reality / F. Chemistry / 1. Chemistry
17469 'H2O' just gives the element proportions, not the microstructure [Weisberg/Needham/Hendry]
17468 Over 100,000,000 compounds have been discovered or synthesised [Weisberg/Needham/Hendry]
17470 Water molecules dissociate, and form large polymers, explaining its properties [Weisberg/Needham/Hendry]
17473 It is unlikely that chemistry will ever be reduced to physics [Weisberg/Needham/Hendry]
17474 Quantum theory won't tell us which structure a set of atoms will form [Weisberg/Needham/Hendry]
17475 For temperature to be mean kinetic energy, a state of equilibrium is also required [Weisberg/Needham/Hendry]
27. Natural Reality / F. Chemistry / 2. Modern Elements
17467 Isotopes (such as those of hydrogen) can vary in their rates of chemical reaction [Weisberg/Needham/Hendry]
27. Natural Reality / F. Chemistry / 3. Periodic Table
17466 Mendeleev systematised the elements, and also gave an account of their nature [Weisberg/Needham/Hendry]
