Single Idea 1672
[filed under theme 2. Reason / A. Nature of Reason / 6. Coherence
]
Full Idea
Some optimists think understanding arises only through demonstration, but say there could be demonstration of everything, for it is possible to demonstrate in a circle or reciprocally.
Gist of Idea
Maybe everything could be demonstrated, if demonstration can be reciprocal or circular
Source
Aristotle (Posterior Analytics [c.327 BCE], 72b16)
Book Ref
Aristotle: 'Posterior Analytics (2nd ed)', ed/tr. Barnes,Jonathan [OUP 1993], p.5
A Reaction
I'm an optimist in this sense, though what is being described would probably best be called 'large-scale coherence'. Two reciprocal arguments look bad, but a hundred look good.
