26 ideas

1. Philosophy / F. Analytic Philosophy / 1. Nature of Analysis
Analysis must include definitions, search for simples, concept analysis, and Kant's analysis [Glock]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
Logic is based on transitions between sentences [Prawitz]
5. Theory of Logic / B. Logical Consequence / 1. Logical Consequence
Logical consequence isn't a black box (Tarski's approach); we should explain how arguments work [Prawitz]
5. Theory of Logic / E. Structures of Logic / 2. Logical Connectives / a. Logical connectives
Natural deduction introduction rules may represent 'definitions' of logical connectives [Prawitz]
5. Theory of Logic / H. Proof Systems / 4. Natural Deduction
In natural deduction, inferences are atomic steps involving just one logical constant [Prawitz]
5. Theory of Logic / J. Model Theory in Logic / 1. Logical Models
Model theory looks at valid sentences and consequence, but not how we know these things [Prawitz]
7. Existence / E. Categories / 1. Categories
All descriptive language is classificatory [Dupré]
7. Existence / E. Categories / 2. Categorisation
We should aim for a classification which tells us as much as possible about the object [Dupré]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
Natural kinds don't need essentialism to be explanatory [Dupré]
9. Objects / D. Essence of Objects / 10. Essence as Species
A species might have its essential genetic mechanism replaced by a new one [Dupré]
It seems that species lack essential properties, so they can't be natural kinds [Dupré]
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism
German and British idealism is not about individual ideas, but the intelligibility of reality [Glock]
14. Science / A. Basis of Science / 4. Prediction
The possibility of prediction rests on determinism [Dupré]
18. Thought / C. Content / 5. Twin Earth
Presumably molecular structure seems important because we never have the Twin Earth experience [Dupré]
18. Thought / D. Concepts / 4. Structure of Concepts / h. Family resemblance
We might say that the family resemblance is just a consequence of meaning-as-use [Glock]
The variety of uses of 'game' may be that it has several meanings, and isn't a single concept [Glock]
26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
Phylogenetics involves history, and cladism rests species on splits in lineage [Dupré]
Kinds don't do anything (including evolve) because they are abstract [Dupré]
26. Natural Theory / B. Natural Kinds / 7. Critique of Kinds
Natural kinds are decided entirely by the intentions of our classification [Dupré]
Borders between species are much less clear in vegetables than among animals [Dupré]
Even atoms of an element differ, in the energy levels of their electrons [Dupré]
Ecologists favour classifying by niche, even though that can clash with genealogy [Dupré]
Cooks, unlike scientists, distinguish garlic from onions [Dupré]
Wales may count as fish [Dupré]
27. Natural Reality / G. Biology / 5. Species
Species are the lowest-level classification in biology [Dupré]
The theory of evolution is mainly about species [Dupré]
