13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / a. Coherence as justification
The ultimate test for truth is the systematic interdependence in nature [Green,TH, by Muirhead]
     Full Idea: Systematic interdependence in the world of nature is the ultimate test of truth.
     From: report of T.H. Green (works [1875]) by John H. Muirhead - The Service of the State II
     A reaction: Green (or Muirhead) drifts between coherence as the nature of truth and coherence as the nature of justification. He it is the 'test' for truth, which was Russell's view.
13. Knowledge Criteria / D. Scepticism / 1. Scepticism
Doubts can't exist if they are inexpressible or unanswerable [Wittgenstein]
     Full Idea: Doubt can exist only where a question exists, a question only where an answer can exist, and an answer only where something can be said.
     From: Ludwig Wittgenstein (Tractatus Logico-Philosophicus [1921], 6.51)
     A reaction: I don't agree with any of that. It is typical of the phase when philosophers were mesmerised by language. Cats look puzzled sometimes. A glimmering of doubt may be pre-linguistic, inexpressible and unanswerable, but still feels like a doubt.
