The 17 ideas from W.H. Newton-Smith

For science to be rational, we must explain scientific change rationally [Newton-Smith]
Positivists hold that theoretical terms change, but observation terms don't [Newton-Smith]
Critics attack positivist division between theory and observation [Newton-Smith]
Defeat relativism by emphasising truth and reference, not meaning [Newton-Smith]
A full understanding of 'yellow' involves some theory [Newton-Smith]
We do not wish merely to predict, we also want to explain [Newton-Smith]
Theories generate infinite truths and falsehoods, so they cannot be used to assess probability [Newton-Smith]
All theories contain anomalies, and so are falsified! [Newton-Smith]
The anomaly of Uranus didn't destroy Newton's mechanics - it led to Neptune's discovery [Newton-Smith]
Anomalies are judged against rival theories, and support for the current theory [Newton-Smith]
Why should it matter whether or not a theory is scientific? [Newton-Smith]
The real problem of science is how to choose between possible explanations [Newton-Smith]
If theories are really incommensurable, we could believe them all [Newton-Smith]
De re necessity arises from the way the world is [Newton-Smith]
More truthful theories have greater predictive power [Newton-Smith]
Explaining an action is showing that it is rational [Newton-Smith]
We must assess the truth of beliefs in identifying them [Newton-Smith]
