Page "Gettier problem" Paragraph 43

However, most contemporary epistemologists accept Gettier's conclusion.

Their responses to the Gettier problem, therefore, consist of trying to find alternative analyses of knowledge.

They have struggled to discover and agree upon as a beginning any single notion of truth, or belief, or justifying which is wholly and obviously accepted.

Truth, belief, and justifying have not yet been satisfactorily defined, so that JTB ( justified true belief ) may be defined satisfactorily is still problematical, on account or otherwise of Gettier's examples.

Gettier, for many years a professor at University of Massachusetts Amherst later also was interested in the epistemic logic of Hintikka, a Finnish philosopher at Boston University, who published Knowledge and Belief in 1962.
