2. Reason / A. Nature of Reason / 1. On Reason
Traditionally, rational beliefs are those which are justified by reasons [Psillos]
3. Truth / B. Truthmakers / 5. What Makes Truths / a. What makes truths
Truthmakers are facts 'of' a domain, not something 'in' the domain [Sommers]
4. Formal Logic / A. Syllogistic Logic / 3. Term Logic
'Predicable' terms come in charged pairs, with one the negation of the other [Sommers, by Engelbretsen]
Logic which maps ordinary reasoning must be transparent, and free of variables [Sommers]
5. Theory of Logic / D. Assumptions for Logic / 4. Identity in Logic
Predicate logic has to spell out that its identity relation '=' is an equivalent relation [Sommers]
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
Translating into quantificational idiom offers no clues as to how ordinary thinkers reason [Sommers]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / c. not
Sommers promotes the old idea that negation basically refers to terms [Sommers, by Engelbretsen]
5. Theory of Logic / E. Structures of Logic / 7. Predicates in Logic
Predicates form a hierarchy, from the most general, down to names at the bottom [Sommers]
5. Theory of Logic / K. Features of Logics / 10. Monotonicity
Valid deduction is monotonic - that is, it remains valid if further premises are added [Psillos]
7. Existence / A. Nature of Existence / 6. Criterion for Existence
The 'epistemic fallacy' is inferring what does exist from what can be known to exist [Psillos]
7. Existence / D. Theories of Reality / 2. Realism
Unfortunately for realists, modern logic cannot say that some fact exists [Sommers]
7. Existence / E. Categories / 1. Categories
Categories can't overlap; they are either disjoint, or inclusive [Sommers, by Westerhoff]
8. Modes of Existence / B. Properties / 5. Natural Properties
Scientific properties are defined by the laws that embody them [Psillos, by Ladyman/Ross]
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Powers are claimed to be basic because fundamental particles lack internal structure [Psillos]
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Anaxarchus said that he was not even sure that he knew nothing [Anaxarchus, by Diog. Laertius]
14. Science / A. Basis of Science / 4. Prediction
If we say where Mars was two months ago, we offer an explanation without a prediction [Psillos]
A good barometer will predict a storm, but not explain it [Psillos]
14. Science / C. Induction / 4. Reason in Induction
Induction (unlike deduction) is non-monotonic - it can be invalidated by new premises [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Explanation is either showing predictability, or showing necessity, or showing causal relations [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
Just citing a cause does not enable us to understand an event; we also need a relevant law [Psillos]
The 'covering law model' says only laws can explain the occurrence of single events [Psillos]
If laws explain the length of a flagpole's shadow, then the shadow also explains the length of the pole [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
An explanation can just be a 'causal story', without laws, as when I knock over some ink [Psillos]
There are non-causal explanations, most typically mathematical explanations [Psillos]
14. Science / D. Explanation / 4. Explanation Doubts / a. Explanation as pragmatic
Maybe explanation is entirely relative to the interests and presuppositions of the questioner [Psillos]
An explanation is the removal of the surprise caused by the event [Psillos]
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
It is hard to analyse causation, if it is presupposed in our theory of the functioning of the mind [Psillos]
19. Language / B. Reference / 1. Reference theories
In standard logic, names are the only way to refer [Sommers]
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
Nothing is more usual than to apply to external bodies every internal sensation which they occasion [Psillos]
26. Natural Theory / C. Causation / 1. Causation
Causes clearly make a difference, are recipes for events, explain effects, and are evidence [Psillos]
Theories of causation are based either on regularity, or on intrinsic relations of properties [Psillos]
We can't base our account of causation on explanation, because it is the wrong way round [Psillos]
26. Natural Theory / C. Causation / 2. Types of cause
Three divisions of causal theories: generalist/singularist, intrinsic/extrinsic, reductive/non-reductive [Psillos]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
If causation is 'intrinsic' it depends entirely on the properties and relations of the cause and effect [Psillos]
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
Empiricists tried to reduce causation to explanation, which they reduced to logic-plus-a-law [Psillos]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Counterfactual claims about causation imply that it is more than just regular succession [Psillos]
26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities
"All gold cubes are smaller than one cubic mile" is a true universal generalisation, but not a law [Psillos]
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
Regularity doesn't seem sufficient for causation [Psillos]
It is not a law of nature that all the coins in my pocket are euros, though it is a regularity [Psillos]
A Humean view of causation says it is regularities, and causal facts supervene on non-causal facts [Psillos]
The regularity of a cock's crow is used to predict dawn, even though it doesn't cause it [Psillos]
26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory
Laws are sets of regularities within a simple and strong coherent system of wider regularities [Psillos]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos]
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
In some counterfactuals, the counterfactual event happens later than its consequent [Psillos]
Counterfactual theories say causes make a difference - if c hadn't occurred, then e wouldn't occur [Psillos]
