Classical logic is bivalent, has excluded middle, and only quantifies over existent objects [Jacquette]
|
|
Full Idea:
Classical logic (of Whitehead, Russell, Gödel, Church) is a two-valued system of propositional and predicate logic, in which all propositions are exclusively true or false, and quantification and predication are over existent objects only.

From:
Dale Jacquette (Intro to I: Classical Logic [2002], p.9)

A reaction:
All of these get challenged at some point, though the existence requirement is the one I find dubious.

Bodily movements are not actions, which are really the tryings within bodily movement [Hornsby, by Stout,R]
|
|
Full Idea:
Hornsby claims the basic description of action is in terms of trying, that all actions (even means of doing other actions) are actions of trying, and that tryings (and therefore actions) are interior to bodily movements (which are thus not essential).

From:
report of Jennifer Hornsby (Actions [1980]) by Rowland Stout - Action 9 'Trying'
|
|
A reaction:
[compression of his summary] There is no regress with explaining the 'action' of trying, because it is proposed that trying is the most basic thing in all actions. If you are paralysed, your trying does not result in action. Too mentalistic?
