摘要：The existence of a generally accepted defi nition of “knowledge” would have a great importance for the social sciences and humanities. The work analyzes the definition of knowledge as a “true judgment with an account”, which was presented in Plato’s dialogue Theaetetus. Advantages and disadvantages of this defi nition are pointed out and particular attention is paid to the analysis of the concept of the “account”, in the context of Plato’s unwritten theories. This conception of knowledge is acceptable under the condition that we acknowledge the complexity of the concept of the “account” and if we accept that the main objections to this conception (for example, the Gettier counterexamples) have their basis exactly in the fact that many meanings of the concept of “account” exist.
