Explain logical necessity by logical consequence, or the other way around? [Correia]
|
|
Full Idea:
One view is that logical consequence is to be understood in terms of logical necessity (some proposition holds necessarily, if some group of other propositions holds). Alternatively, logical necessity is a logical consequence of the empty set.

From:
Fabrice Correia (On the Reduction of Necessity to Essence [2012], 3)

|
A reaction:
I think my Finean preference is for all necessities to have a 'necessitator', so logical necessity results from logic in some way, perhaps from logical consequence, or from the essences of the connectives and operators.

'Good' is an attributive adjective like 'large', not predicative like 'red' [Geach, by Foot]
|
|
Full Idea:
Geach puts 'good' in the class of attributive adjectives, such as 'large' and 'small', contrasting such adjectives with 'predicative' adjectives such as 'red'.
|

From:
report of Peter Geach (Good and Evil [1956]) by Philippa Foot - Natural Goodness Intro
|
|
A reaction:
[In Analysis 17, and 'Theories of Ethics' ed Foot] Thus any object can simply be red, but something can only be large or small 'for a rat' or 'for a car'. Hence nothing is just good, but always a good so-and-so. This is Aristotelian, and Foot loves it.
