2744 | Verificationism (the 'verification principle') is an earlier form of anti-realism [Dancy,J] |
2760 | Logical positivism implies foundationalism, by dividing weak from strong verifications [Dancy,J] |

2763 | There is an indeterminacy in juggling apparent meanings against probable beliefs [Dancy,J] |
