14. Science / A. Basis of Science / 4. Prediction
Correlations can provide predictions, but only causes can give explanations [Salmon]
14. Science / B. Scientific Theories / 1. Scientific Theory
Clavius's Paradox: purely syntactic entailment theories won't explain, because they are too profuse [Harré/Madden]
Simplicity can sort theories out, but still leaves an infinity of possibilities [Harré/Madden]
The powers/natures approach has been so successful (for electricity, magnetism, gravity) it may be universal [Harré/Madden]
14. Science / B. Scientific Theories / 2. Aim of Science
We prefer the theory which explains and predicts the powers and capacities of particulars [Harré/Madden]
Science investigates the nature and constitution of things or substances [Harré/Madden]
14. Science / B. Scientific Theories / 3. Instrumentalism
For the instrumentalists there are no scientific explanations [Salmon]
14. Science / C. Induction / 3. Limits of Induction
Conjunctions explain nothing, and so do not give a reason for confidence in inductions [Harré/Madden]
Hume's atomic events makes properties independent, and leads to problems with induction [Harré/Madden]
14. Science / C. Induction / 4. Reason in Induction
Good induction needs 'total evidence' - the absence at the time of any undermining evidence [Salmon]
14. Science / C. Induction / 5. Paradoxes of Induction / b. Raven paradox
Contraposition may be equivalent in truth, but not true in nature, because of irrelevant predicates [Harré/Madden]
The items put forward by the contraposition belong within different natural clusters [Harré/Madden]
The possibility that all ravens are black is a law depends on a mechanism producing the blackness [Harré/Madden]
14. Science / D. Explanation / 1. Explanation / b. Aims of explanation
Scientific explanation is not reducing the unfamiliar to the familiar [Salmon]
Only changes require explanation [Harré/Madden]
Why-questions can seek evidence as well as explanation [Salmon]
14. Science / D. Explanation / 1. Explanation / c. Direction of explanation
If explanation is by entailment, that lacks a causal direction, unlike natural necessity [Harré/Madden]
Powers can explain the direction of causality, and make it a natural necessity [Harré/Madden]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
The 'inferential' conception is that all scientific explanations are arguments [Salmon]
Ontic explanations can be facts, or reports of facts [Salmon]
An explanation is a table of statistical information [Salmon, by Strevens]
The three basic conceptions of scientific explanation are modal, epistemic, and ontic [Salmon]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
We must distinguish true laws because they (unlike accidental generalizations) explain things [Salmon]
Deductive-nomological explanations will predict, and their predictions will explain [Salmon]
A law is not enough for explanation - we need information about what makes a difference [Salmon]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
Flagpoles explain shadows, and not vice versa, because of temporal ordering [Salmon]
14. Science / D. Explanation / 2. Types of Explanation / i. Explanations by mechanism
Causation produces productive mechanisms; to understand the world, understand these mechanisms [Salmon]
Salmon's interaction mechanisms needn't be regular, or involving any systems [Glennan on Salmon]
Explanation at the quantum level will probably be by entirely new mechanisms [Salmon]
Does an item have a function the first time it occurs? [Salmon]
Explanations reveal the mechanisms which produce the facts [Salmon]
Salmon's mechanisms are processes and interactions, involving marks, or conserved quantities [Salmon, by Machamer/Darden/Craver]
If the nature of particulars explains their powers, it also explains their relations and behaviour [Harré/Madden]
Powers and natures lead us to hypothesise underlying mechanisms, which may be real [Harré/Madden]
14. Science / D. Explanation / 2. Types of Explanation / j. Explanations by reduction
Solidity comes from the power of repulsion, and shape from the power of attraction [Harré/Madden]
14. Science / D. Explanation / 2. Types of Explanation / k. Explanations by essence
Essence explains passive capacities as well as active powers [Harré/Madden]
14. Science / D. Explanation / 2. Types of Explanation / l. Probabilistic explanations
Can events whose probabilities are low be explained? [Salmon]
Statistical explanation needs relevance, not high probability [Salmon]
Think of probabilities in terms of propensities rather than frequencies [Salmon]
