5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
Intuitionists deny excluded middle, because it is committed to transcendent truth or objects [Shapiro]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / b. Types of number
The number 3 is presumably identical as a natural, an integer, a rational, a real, and complex [Shapiro]
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / h. Reals from Cauchy
Cauchy gave a formal definition of a converging sequence. [Shapiro]
6. Mathematics / B. Foundations for Mathematics / 1. Foundations for Mathematics
Categories are the best foundation for mathematics [Shapiro]
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / f. Zermelo numbers
Two definitions of 3 in terms of sets disagree over whether 1 is a member of 3 [Shapiro]
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / a. Structuralism
Numbers do not exist independently; the essence of a number is its relations to other numbers [Shapiro]
A 'system' is related objects; a 'pattern' or 'structure' abstracts the pure relations from them [Shapiro]
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Logicism seems to be a non-starter if (as is widely held) logic has no ontology of its own [Shapiro]
6. Mathematics / C. Sources of Mathematics / 7. Formalism
Term Formalism says mathematics is just about symbols - but real numbers have no names [Shapiro]
Game Formalism is just a matter of rules, like chess - but then why is it useful in science? [Shapiro]
Deductivism says mathematics is logical consequences of uninterpreted axioms [Shapiro]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / b. Intuitionism
Critics resent the way intuitionism cripples mathematics, but it allows new important distinctions [Shapiro]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / c. Conceptualism
Conceptualist are just realists or idealist or nominalists, depending on their view of concepts [Shapiro]
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / d. Predicativism
'Impredicative' definitions refer to the thing being described [Shapiro]
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Rationalism tries to apply mathematical methodology to all of knowledge [Shapiro]
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]
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]
There may be a justification relative to a person's view, and yet no absolute justification [Stout,R]
20. Action / C. Motives for Action / 5. Action Dilemmas / b. Double Effect
Describing a death as a side-effect rather than a goal may just be good public relations [Stout,R]
24. Political Theory / B. Nature of a State / 2. State Legitimacy / d. General will
The real will of the cooperative will replace the 'will of the people' [Marx]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Aristotelian causation involves potentiality inputs into processes (rather than a pair of events) [Stout,R]
