This is an attempt to investigate two opposite positions in the controversy about justification of knowledge - foundationalism and coherentism. The author refers to the views of Edmund Gettier, Ernst Sosa and Keith Lehrer. The main findings can be summarized as follows. The author argues that the two opposite positions are not dramatically contrary. Moreover, taking a clue from Sosa, he distinguishes an ideal of knowledge based on formal criteria from substantive knowledge that bears the stamp of revocable theory. Finally, going in the footsteps of Lehrer, he identifies genuine knowledge with a search for truth and indicates that a new form of justification of knowledge is to be looked-for in the hope that the new approach will redefine such concepts as relativism, skepticism and epistemological realism.
