chapter 6: epistemology

Belief: A mental state of acceptance (a belief could be false).
Justification: The reasons why one holds a belief (there are good and bad justifications).
Truth: Truth is a fact.
Suspension of belief. Neither accept nor reject a belief.

Theories of truth
Correspondence Theory: Truth is a fact (example: "Snow is white.") 
Pragmatic Theory: Truth is what best does the job at hand (example: "Dom Perignon is a good champagne.")
Coherence Theory of Truth: Truth is what best coheres with the rest of my knowledge (example: "The theory of evolution is true because it best coheres with the rest of our natural sciences").

When we don't have all the evidence, or when we're dealing with complicated problems, we may use the pragmatic criteria: With history, forensics, matters of opinion and taste we are more likely to deal with truth as pragmatic than as correspondence. 

Guess which theories are expressed by these propositions:
a- "2+3 =5", 
b- "all triangles have three sides," 
c- "H2O is water,"  
d- "Democracy is better than tyranny." 
e- "Les Desmoiselles d'Avignon by Picasso is a masterpiece of Cubism."

Section 7.1 & Section 7.2 are summarized here.
