Maybe modal thought is unavoidable, as a priori recognition of necessary truth-preservation in reasoning [Hale/Hoffmann,A]
|
|
Full Idea:
There are 'transcendental' arguments saying that modal thought is unavoidable - recognition, a priori, of the necessarily truth-preserving character of some forms of inference is a precondition for rational thought in general, and scientific theorizing.

From:
Bob Hale/ Aviv Hoffmann (Introduction to 'Modality' [2010], 1)
|
|
A reaction:
So the debate about the status of logical truths and valid inference, are partly debates about whether out thought has to involve modality, or whether it could just be about the actual world. I take possibilities and necssities to be features of nature.

In primary evaluative words like 'ought' prescription is constant but description can vary [Hare, by Hooker,B]
|
|
Full Idea:
Hare says words are secondarily evaluative (e.g. 'soft-hearted') if prescriptive meaning varies but description is constant; primarily evaluative words ('good', 'right', 'ought') are the opposite, with the descriptive content varying.

From:
report of Richard M. Hare (The Language of Morals [1952]) by Brad W. Hooker - Prescriptivism p.640
|
|
A reaction:
I would have thought that the prescriptive meaning of the evaluative word could at least vary in strength. You really, really ought to do that.
