A theory that understood this concept using causal chains was later challenged with “fake barn” cases introduced (-5[1])by the (10[1])reliabilist (10[2])thinker Alvin Goldman. Four conditions need to be met in the truth-tracking theory (10[1])of this concept proposed by Robert Nozick. A three-page 1963 paper (10[1])challenges a definition of this concept (10[1])with a case (-5[1])where Smith thinks Jones (10[3])will get (10[1]-5[1])a job (10[1])and also has (-5[1])ten coins in his pocket. (10[1]-5[1])That case, (-5[1])developed by Edmund Gettier, (10[1]-5[1])challenges (-5[1])Plato’s (10[1])definition of this concept (10[1])in the (10[2]-5[1])Theaetetus (10[1]-5[1])as “justified true (10[3])belief.” (10[9]-5[1])This concept is (-5[1])studied (10[1]-5[1])in epistemology. (10[5]-5[2])For (10[1])10 (10[1])points, (10[3]-5[1])skeptics doubt the existence (-5[1])of (10[1]-5[1])what concept (10[1]-5[1])that Francis Bacon claimed “is power”? (10[5])■END■ (10[14]0[1])
