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]
     Full Idea: Defining logical consequence in the way Tarski does is a rather meagre result, treating an argument as a black box, observing input and output, while disregarding inner structure. We should define logical consequence on the basis of valid arguments.
     From: Dag Prawitz (On the General Idea of Proof Theory [1974], §2)
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]
     Full Idea: In model theory, which has dominated the last decades, one concentrates on logically valid sentences, and what follows logically from what, but one disregards questions concerning how we know these things.
     From: Dag Prawitz (On the General Idea of Proof Theory [1974], §1)
15. Nature of Minds / B. Features of Minds / 5. Qualia / b. Qualia and intentionality
The qualities involved in sensations are entirely intentional [Anscombe, by Armstrong]
     Full Idea: Anscombe argued that the qualities involved in sensations are one and all intentional only (and I think this holds even for the bodily sensations).
     From: report of G.E.M. Anscombe (The Intentionality of Sensation [1965]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xxii
     A reaction: Compare Harry Gildersleve's exactly opposite proposal in Idea 7272. I think I am coming round to the Anscombe view, which builds the more mysterious up from the less mysterious. Gildersleve must explain how atomic qualia arise.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / e. Human nature
There are two sides to men - the pleasantly social, and the violent and creative [Diderot, by Berlin]
     Full Idea: Diderot is among the first to preach that there are two men: the artificial man, who belongs in society and seeks to please, and the violent, bold, criminal instinct of a man who wishes to break out (and, if controlled, is responsible for works of genius.
     From: report of Denis Diderot (works [1769], Ch.3) by Isaiah Berlin - The Roots of Romanticism
     A reaction: This has an obvious ancestor in Plato's picture (esp. in 'Phaedrus') of the two conflicting sides to the psuché, which seem to be reason and emotion. In Diderot, though, the suppressed man has virtues, which Plato would deny.
