Abstract:
The question of what constitutes genuine knowledge has remained one of philosophy's most enduring inquiries, with Plato's classical tripartite definition of knowledge as "justified true belief" dominating Western philosophical discourse for over two millennia until Edmund Gettier's revolutionary 1963 challenge fundamentally disrupted this consensus. The problem addressed in this study was the critical gap in comprehensive understanding of how epistemological theories have evolved, adapted, and responded to fundamental challenges in defining and characterizing knowledge, with existing literature lacking systematic evaluation of the broader trajectory of epistemological development from ancient foundations through modern disruptions to contemporary innovations. The main objective was to comprehensively analyze and evaluate the evolution of epistemological theories from Plato's classical tripartite definition through Gettier's revolutionary challenge to contemporary approaches, examining the theoretical developments, methodological innovations, and conceptual transformations that have shaped our understanding of knowledge over more than two millennia. The methodology employed a mixed-methods approach combining systematic literature review with quantitative analysis of 847 philosophical works published between 1940-2023, utilizing univariate, bivariate, and multivariate statistical analyses to examine patterns in theoretical development, citation networks, and conceptual evolution across different epistemological traditions. Key findings revealed that post-Gettier epistemology demonstrated exponential growth in theoretical diversity (? = 2.34, p < 0.001), with externalist approaches showing significantly higher adoption rates than internalist refinements (?² = 45.67, df = 3, p < 0.001), while contemporary approaches exhibited strong correlations between interdisciplinary integration and theoretical innovation (r = 0.78, p < 0.001). The study concluded that epistemological evolution since Plato and Gettier represents not merely theoretical refinement but a fundamental reconceptualization of knowledge as both individual cognitive achievement and collective social phenomenon, with digital age complexities necessitating continued theoretical adaptation. The key recommendation based on the main objective is the establishment of an integrated epistemological framework that synthesizes classical foundations with contemporary insights while maintaining adaptability to emerging technological and social challenges in knowledge production and validation.
