13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / b. Gettier problem

8886	Being a true justified belief is not a sufficient condition for knowledge [Gettier]
	Full Idea: The claim that someone knows a proposition if it is true, it is believed, and the person is justified in their belief is false, in that the conditions do not state a sufficient condition for the claim.
	From: Edmund L. Gettier (Is Justified True Belief Knowledge? [1963], p.145)
	A reaction: This is the beginning of the famous Gettier Problem, which has motivated most epistemology for the last forty years. Gettier implies that justification is necessary, even if it is not sufficient. He gives two counterexamples.

13. Knowledge Criteria / E. Relativism / 2. Knowledge as Convention

10347	Objectivity is intersubjectivity [Davidson]
	Full Idea: An entity is objective in so far as it is intersubjective.
	From: Donald Davidson (Three Varieties of Knowledge [1991]), quoted by Martin Kusch - Knowledge by Agreement Ch.10
	A reaction: This thought baffled me until I saw it in the context of socialised epistemology. Effectively objectivity is subsumed under justification, which in turn is seen in a social context, not private to individuals.
