1. Philosophy / F. Analytic Philosophy / 6. Logical Analysis
Frege changed philosophy by extending logic's ability to check the grounds of thinking [Potter on Frege]
2. Reason / B. Laws of Thought / 1. Laws of Thought
We should not describe human laws of thought, but how to correctly track truth [Frege, by Fisher]
4. Formal Logic / C. Predicate Calculus PC / 1. Predicate Calculus PC
I don't use 'subject' and 'predicate' in my way of representing a judgement [Frege]
4. Formal Logic / C. Predicate Calculus PC / 2. Tools of Predicate Calculus / d. Universal quantifier ∀
For Frege, 'All A's are B's' means that the concept A implies the concept B [Frege, by Walicki]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
Frege has a judgement stroke (vertical, asserting or judging) and a content stroke (horizontal, expressing) [Frege, by Weiner]
The laws of logic are boundless, so we want the few whose power contains the others [Frege]
5. Theory of Logic / A. Overview of Logic / 2. History of Logic
In 1879 Frege developed second order logic [Frege, by Putnam]
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
Frege replaced Aristotle's subject/predicate form with function/argument form [Frege, by Weiner]
5. Theory of Logic / G. Quantification / 1. Quantification
A quantifier is a second-level predicate (which explains how it contributes to truth-conditions) [Frege, by George/Velleman]
5. Theory of Logic / G. Quantification / 2. Domain of Quantification
For Frege the variable ranges over all objects [Frege, by Tait]
Frege's domain for variables is all objects, but modern interpretations first fix the domain [Dummett on Frege]
5. Theory of Logic / G. Quantification / 3. Objectual Quantification
Frege introduced quantifiers for generality [Frege, by Weiner]
Frege reduced most quantifiers to 'everything' combined with 'not' [Frege, by McCullogh]
5. Theory of Logic / H. Proof Systems / 1. Proof Systems
Proof theory began with Frege's definition of derivability [Frege, by Prawitz]
5. Theory of Logic / H. Proof Systems / 2. Axiomatic Proof
Frege produced axioms for logic, though that does not now seem the natural basis for logic [Frege, by Kaplan]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / f. Mathematical induction
It may be possible to define induction in terms of the ancestral relation [Frege, by Wright,C]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / b. Type theory
Frege's logic has a hierarchy of object, property, property-of-property etc. [Frege, by Smith,P]
7. Existence / A. Nature of Existence / 1. Nature of Existence
Existence is not a first-order property, but the instantiation of a property [Frege, by Read]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Evolutionary explanations look to the past or the group, not to the individual [Stout,R]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Not all explanation is causal. We don't explain a painting's beauty, or the irrationality of root-2, that way [Stout,R]
19. Language / C. Assigning Meanings / 4. Compositionality
Frege's account was top-down and decompositional, not bottom-up and compositional [Frege, by Potter]
20. Action / A. Definition of Action / 1. Action Theory
Philosophy of action studies the nature of agency, and of deliberate actions [Stout,R]
Agency is causal processes that are sensitive to justification [Stout,R]
20. Action / A. Definition of Action / 2. Duration of an Action
Mental states and actions need to be separate, if one is to cause the other [Stout,R]
Are actions bodily movements, or a sequence of intention-movement-result? [Stout,R]
If one action leads to another, does it cause it, or is it part of it? [Stout,R]
20. Action / A. Definition of Action / 3. Actions and Events
I do actions, but not events, so actions are not events [Stout,R]
20. Action / A. Definition of Action / 4. Action as Movement
Bicycle riding is not just bodily movement - you also have to be on the bicycle [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / a. Nature of intentions
The rationalistic approach says actions are intentional when subject to justification [Stout,R]
The causal theory says that actions are intentional when intention (or belief-desire) causes the act [Stout,R]
Deciding what to do usually involves consulting the world, not our own minds [Stout,R]
Should we study intentions in their own right, or only as part of intentional action? [Stout,R]
You can have incompatible desires, but your intentions really ought to be consistent [Stout,R]
The normativity of intentions would be obvious if they were internal promises [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / b. Types of intention
Intentional agency is seen in internal precursors of action, and in external reasons for the act [Stout,R]
Speech needs sustained intentions, but not prior intentions [Stout,R]
20. Action / B. Preliminaries of Action / 1. Intention to Act / d. Group intentions
Bratman has to treat shared intentions as interrelated individual intentions [Stout,R]
A request to pass the salt shares an intention that the request be passed on [Stout,R]
An individual cannot express the intention that a group do something like moving a piano [Stout,R]
An intention is a goal to which behaviour is adapted, for an individual or for a group [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / b. Volitionism
If the action of walking is just an act of will, then movement of the legs seems irrelevant [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / c. Agent causation
Most philosophers see causation as by an event or state in the agent, rather than the whole agent [Stout,R]
If you don't mention an agent, you aren't talking about action [Stout,R]
20. Action / B. Preliminaries of Action / 2. Willed Action / d. Weakness of will
If you can judge one act as best, then do another, this supports an inward-looking view of agency [Stout,R]
20. Action / C. Motives for Action / 1. Acting on Desires
Maybe your emotions arise from you motivations, rather than being their cause [Stout,R]
For an ascetic a powerful desire for something is a reason not to implement it [Stout,R]
20. Action / C. Motives for Action / 3. Acting on Reason / c. Reasons as causes
Beliefs, desires and intentions are not events, so can't figure in causal relations [Stout,R]
A standard view says that the explanation of an action is showing its rational justification [Stout,R]
In order to be causal, an agent's reasons must be internalised as psychological states [Stout,R]
20. Action / C. Motives for Action / 4. Responsibility for Actions
An action is only yours if you produce it, rather than some state or event within you [Stout,R]

The predicate 'exists' is actually a natural language expression for a quantifier [Frege, by Weiner]
