2. Reason / D. Definition / 11. Ostensive Definition
Ostensive definitions needn't involve pointing, but must refer to something specific [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 2. Tools of Modal Logic / b. Terminology of ML
A world is 'accessible' to another iff the first is possible according to the second [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / d. System T
For metaphysics, T may be the only correct system of modal logic [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / f. System B
System B has not been justified as fallacy-free for reasoning on what might have been [Salmon,N]
In B it seems logically possible to have both p true and p is necessarily possibly false [Salmon,N]
System B implies that possibly-being-realized is an essential property of the world [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / g. System S4
What is necessary is not always necessarily necessary, so S4 is fallacious [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 3. Modal Logic Systems / h. System S5
S4, and therefore S5, are invalid for metaphysical modality [Salmon,N, by Williamson]
S5 modal logic ignores accessibility altogether [Salmon,N]
S5 believers say that-things-might-have-been-that-way is essential to ways things might have been [Salmon,N]
The unsatisfactory counterpart-theory allows the retention of S5 [Salmon,N]
4. Formal Logic / D. Modal Logic ML / 4. Alethic Modal Logic
Metaphysical (alethic) modal logic concerns simple necessity and possibility (not physical, epistemic..) [Salmon,N]
6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
Archimedes defined a straight line as the shortest distance between two points [Archimedes, by Leibniz]
7. Existence / D. Theories of Reality / 10. Vagueness / g. Degrees of vagueness
It can't be indeterminate whether x and y are identical; if x,y is indeterminate, then it isn't x,x [Salmon,N]
9. Objects / D. Essence of Objects / 7. Essence and Necessity / a. Essence as necessary properties
Essentialism says some properties must be possessed, if a thing is to exist [Salmon,N]
9. Objects / D. Essence of Objects / 15. Against Essentialism
Any property is attached to anything in some possible world, so I am a radical anti-essentialist [Salmon,N]
10. Modality / A. Necessity / 3. Types of Necessity
Logical possibility contains metaphysical possibility, which contains nomological possibility [Salmon,N]
10. Modality / A. Necessity / 5. Metaphysical Necessity
In the S5 account, nested modalities may be unseen, but they are still there [Salmon,N]
Metaphysical necessity is said to be unrestricted necessity, true in every world whatsoever [Salmon,N]
Bizarre identities are logically but not metaphysically possible, so metaphysical modality is restricted [Salmon,N]
Without impossible worlds, the unrestricted modality that is metaphysical has S5 logic [Salmon,N]
Metaphysical necessity is NOT truth in all (unrestricted) worlds; necessity comes first, and is restricted [Salmon,N]
10. Modality / A. Necessity / 6. Logical Necessity
Logical necessity is free of constraints, and may accommodate all of S5 logic [Salmon,N]
10. Modality / A. Necessity / 7. Natural Necessity
Nomological necessity is expressed with intransitive relations in modal semantics [Salmon,N]
10. Modality / C. Sources of Modality / 5. Modality from Actuality
Necessity and possibility are not just necessity and possibility according to the actual world [Salmon,N]
10. Modality / E. Possible worlds / 1. Possible Worlds / b. Impossible worlds
Impossible worlds are also ways for things to be [Salmon,N]
Denial of impossible worlds involves two different confusions [Salmon,N]
Without impossible worlds, how things might have been is the only way for things to be [Salmon,N]
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
Possible worlds rely on what might have been, so they can' be used to define or analyse modality [Salmon,N]
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / a. Nature of possible worlds
Possible worlds are maximal abstract ways that things might have been [Salmon,N]
Possible worlds just have to be 'maximal', but they don't have to be consistent [Salmon,N]
10. Modality / E. Possible worlds / 2. Nature of Possible Worlds / c. Worlds as propositions
You can't define worlds as sets of propositions, and then define propositions using worlds [Salmon,N]
19. Language / B. Reference / 1. Reference theories
Frege's 'sense' solves four tricky puzzles [Salmon,N]
19. Language / B. Reference / 3. Direct Reference / a. Direct reference
The perfect case of direct reference is a variable which has been assigned a value [Salmon,N]
Kripke and Putnam made false claims that direct reference implies essentialism [Salmon,N]

All states aim at preservation, and then have distinctive individual purposes [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / a. Autocracy
The natural power of a father suggests rule by one person, but that authority can be spread [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
Monarchies can act more quickly, because one person is in charge [Montesquieu]
The nobility are an indispensable part of a monarchy [Montesquieu]

24. Political Theory / C. Ruling a State / 2. Leaders / c. Despotism
A despot's agents must be given power, so they inevitably become corrupt [Montesquieu]
Despotism and honour are incompatible, because honour scorns his power, and lives by rules [Montesquieu]
Tyranny is either real violence, or the imposition of unpopular legislation [Montesquieu]
Despots are always lazy and ignorant, so they always delegate their power to a vizier [Montesquieu]
The will of a despot is an enigma, so magistrates can only follow their own will [Montesquieu]
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
If the nobility is numerous, the senate is the artistocracy, and the nobles are a democracy [Montesquieu]
Aristocracy is democratic if they resemble the people, but not if they resemble the monarch [Montesquieu]
Great inequality between aristocrats and the rest is bad - and also among aristocrats themselves [Montesquieu]
24. Political Theory / C. Ruling a State / 3. Government / a. Government

A government has a legislature, an international executive, and a domestic executive [Montesquieu]

If deputies represent people, they are accountable, but less so if they represent places [Montesquieu]
25. Social Practice / A. Freedoms / 1. Slavery
Slaves are not members of the society, so no law can forbid them to run away [Montesquieu]
Slavery is entirely bad; the master abandons the virtues, and they are pointless in the slave [Montesquieu]
The demand for slavery is just the masters' demand for luxury [Montesquieu]

Democracy is corrupted by lack of equality, or by extreme equality (between rulers and ruled) [Montesquieu]

25. Social Practice / D. Justice / 3. Punishment / a. Right to punish
The death penalty is permissible, because its victims enjoyed the protection of that law [Montesquieu]
