1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Metaphysics can criticise interpretations of science theories, and give good feedback [Ingthorsson]
5. Theory of Logic / A. Overview of Logic / 5. First-Order Logic
Philosophers accepted first-order logic, because they took science to be descriptive, not explanatory [Ingthorsson]
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]
7. Existence / B. Change in Existence / 2. Processes
Basic processes are said to be either physical, or organic, or psychological [Ingthorsson]
7. Existence / D. Theories of Reality / 2. Realism
Indirect realists are cautious about the manifest image, and prefer the scientific image [Ingthorsson]
8. Modes of Existence / A. Relations / 1. Nature of Relations
Neo-Humeans say there are no substantial connections between anything [Ingthorsson]
8. Modes of Existence / B. Properties / 3. Types of Properties
Properties are said to be categorical qualities or non-qualitative dispositions [Ingthorsson]
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Physics understands the charge of an electron as a power, not as a quality [Ingthorsson]
9. Objects / A. Existence of Objects / 1. Physical Objects
Compound objects are processes, insofar as change is essential to them [Ingthorsson]
9. Objects / A. Existence of Objects / 5. Simples
Most materialist views postulate smallest indivisible components which are permanent [Ingthorsson]
9. Objects / E. Objects over Time / 1. Objects over Time
Endurance and perdurance just show the consequences of A or B series time [Ingthorsson]
Science suggests causal aspects of the constitution and persistance of objects [Ingthorsson]
9. Objects / E. Objects over Time / 4. Four-Dimensionalism
If causation involves production, that needs persisting objects [Ingthorsson]
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
Every philosophical theory must be true in some possible world, so the ontology is hopeless [Ingthorsson]
Worlds may differ in various respects, but no overall similarity of worlds is implied [Ingthorsson]
12. Knowledge Sources / C. Rationalism / 1. Rationalism
Rationalism tries to apply mathematical methodology to all of knowledge [Shapiro]
26. Natural Theory / C. Causation / 2. Types of cause
Humeans describe the surface of causation, while powers accounts aim at deeper explanations [Ingthorsson]
Time and space are not causal, but they determine natural phenomena [Ingthorsson]
26. Natural Theory / C. Causation / 4. Naturalised causation
Casuation is the transmission of conserved quantities between causal processes [Ingthorsson]
Causation as transfer only works for asymmetric interactions [Ingthorsson]
Interventionist causal theory says it gets a reliable result whenever you manipulate it [Ingthorsson]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
Causal events are always reciprocal, and there is no distinction of action and reaction [Ingthorsson]
One effect cannot act on a second effect in causation, because the second doesn't yet exist [Ingthorsson]
Empiricists preferred events to objects as the relata, because they have observable motions [Ingthorsson]
Science now says all actions are reciprocal, not unidirectional [Ingthorsson]
Causes are not agents; the whole interaction is the cause, and the changed compound is the effect [Ingthorsson]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
People only accept the counterfactual when they know the underlying cause [Ingthorsson]
Counterfactuals don't explain causation, but causation can explain counterfactuals [Ingthorsson]
Counterfactual theories are false in possible worlds where causation is actual [Ingthorsson]
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
A cause can fail to produce its normal effect, by prevention, pre-emption, finks or antidotes [Ingthorsson]
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
Any process can go backwards or forwards in time without violating the basic laws of physics [Ingthorsson]
27. Natural Reality / A. Classical Physics / 1. Mechanics / b. Laws of motion
In modern physics the first and second laws of motion (unlike the third) fail at extremes [Ingthorsson]
27. Natural Reality / B. Modern Physics / 4. Standard Model / a. Concept of matter
If particles have decay rates, they can't really be elementary, in the sense of indivisible [Ingthorsson]
27. Natural Reality / D. Time / 1. Nature of Time / h. Presentism
It is difficult to handle presentism in first-order logic [Ingthorsson]
28. God / C. Attitudes to God / 5. Atheism
Stilpo said if Athena is a daughter of Zeus, then a statue is only the child of a sculptor, and so is not a god [Stilpo, by Diog. Laertius]
