Single Idea 18284

[filed under theme 14. Science / A. Basis of Science / 6. Falsification ]

Full Idea

Whereas particular reality statements are in principle completely verifiable or falsifiable, things are different for general reality statements: they can indeed be conclusively falsified, they can acquire a negative truth value, but not a positive one.

Gist of Idea

Particulars can be verified or falsified, but general statements can only be falsified (conclusively)

Source

A Reaction

This sounds like a logician's approach to science, but I prefer to look at coherence, where very little is actually conclusive, and one tinkers with the theory instead.
