19. Language / A. Nature of Meaning / 5. Meaning as Verification
Perhaps logical positivism showed that there is no dividing line between science and metaphysics [Lockwood]
     Full Idea: If the logical positivists established anything it is that there is no way of demarcating science from metaphysics.
     From: Michael Lockwood (Mind, Brain and the Quantum [1989], p.313)
     A reaction: So many problems arise for philosophers because of the passion for 'demarcating' things. Close study, experiments, statistics and measurements occur in every walk of life.
19. Language / C. Assigning Meanings / 7. Extensional Semantics
Equilateral and equiangular aren't the same, as we have to prove their connection [Shalkowski]
     Full Idea: That 'all and only equilateral triangles are equiangular' required proof, and not for mere curiosity, is grounds for thinking that being an equilateral triangle is not the same property as being an equiangular triangle.
     From: Scott Shalkowski (Essence and Being [2008], 'Serious')
     A reaction: If you start with equiangularity, does equilateralness then require proof? This famous example is of two concepts which seem to be coextensional, but seem to have a different intension. Does a dependence relation drive a wedge between them?
