19053 | Logic would be more natural if negation only referred to predicates [Dummett] |
Full Idea: A better proposal for a formal logic closer to natural language would be one that had a negation-operator only for (simple) predicates. | |
From: Michael Dummett (Presupposition [1960], p.27) | |
A reaction: Dummett observes that classical formal logic was never intended to be close to natural language. Term logic does have that aim, but the meta-question is whether that end is desirable, and why. |
19052 | Natural language 'not' doesn't apply to sentences [Dummett] |
Full Idea: Natural language does not possess a sentential negation-operator. | |
From: Michael Dummett (Presupposition [1960], p.27) | |
A reaction: This is a criticism of Strawson, who criticises logic for not following natural language, but does it himself with negation. In the question of how language and logic connect, this idea seems important. Term Logic aims to get closer to natural language. |
8790 | The 'doctrine of the given' is correct; some beliefs or statements are self-justifying [Chisholm] |
Full Idea: In my opinion, the 'doctrine of the given' is correct in saying that there are some beliefs or statements which are 'self-justifying' and that among such beliefs are statements some of which concern appearances or 'ways of being appeared to'. | |
From: Roderick Chisholm (The Myth of the Given [1964], §12) | |
A reaction: To boldly assert that they are 'self-justifying' invites a landslide of criticisms, pointing at a regress. It might be better to say they are self-evident, or intuitively known, or primitive, or true by the natural light of reason. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
