Theories, that answering the question “What is knowledge?” in analytic epistemology appears under the influence of Gettier cases - a way of refutation such theories of knowledge, that have truth and belief as constituent elements. In the paper were analyzed basic strategies of solving the Gettier problem. One way is to save the analysis of knowledge by changing the elements in order to avoid the Gettier problem. There are three possible ways of doing so: adding new elements to the justification, changing the justification on the other criteria or strengthen the justification in such a way, that it would resolve any possible Gettier cases. For each strategy analysis of the theories of knowledge is given. In the paper idea of the inescapability of Gettier cases for analysis of knowledge was supported by the argumentation of Linda Zagzebski. In that ground, the analysis of knowledge was refuted. From that perspective, two of the most influenced ways of answering the question “what is knowledge” was proposed. Fir
