Views of the nature of truth:

1. correspondence (Russell)

A proposition p is true iff p corresponds to (or mirrors) the fact that p indicates

2. coherence (Blanshard)

A proposition p is true iff p coheres with a large mass of other propositions

3. semantic (Tarski)

"Snow is white" is true iff snow is white

(X is true, where is X is the name of p, iff p)

4. pragmatic (Pierce, James, Dewey)

Pierce: A proposition p is true iff p is that upon which scientific inquiry converges over the long run (ideal limit)

James: A proposition p is true iff p is verifiable (through success in action)

Dewey: A proposition p is true iff p is justifiably asserted (warranted assertibility)
