B a c k g r o u n d. The current research focuses on Ukraine's academic philosophical culture in the second half of the 20th century during the Soviet era, emphasising the historical and methodological bases of truth interpretation by its representatives. Using descriptive methodology and comparative analysis, it was found that the Ukrainian academic philosophy of this period, represented here by the legacy of recognised figures often referred to in the philosophical literature as the Kyiv School of Philosophy, (...) is a revival of philosophy in Ukraine based on so-called "authentic" Marxism-Leninism. M e t h o d s. In particular, to analyse the concept of truth, representatives of the Ukrainian academic philosophical culture of the studied period employed the dialectical method, which is interpreted in dialectical materialism through the concept of the "development" of the material universe. Specifically, within this dialectics of nature, dialectical negation is considered a stage of object development in which the achievements of the earlier stages are not eliminated but rather "removed" – contained within it. R e s u l t s. The interpretation of logic as a theoretical reflection of historical patterns in theoretical form enabled them to define truth as correspondence to reality and analyse it through the lens of the dialectical inter-transformation of the categories of subjective and objective, relative and absolute. The application of the dialectical method to the concepts of "relative" and "absolute" resulted in the identification of "relatively absolute," "absolutely relative" truth, and the opposition of the "relatively absolute truth" to the "absolutely absolute truth." They regard the latter – absolutely absolute truth – as an unreachable ideal that serves as a regulative principle, the pursuit of which promotes cognitive progress through the accumulation of partial, relative truths. C o n c l u s i o n s. Thus, in the second half of the 20th century, during the Soviet era, representatives of Ukraine's academic philosophical culture employed dialectical materialism methodology to define the concept of truth, allowing them to justify the process of cognition as complex and endless. At the same time, as representatives of that era's academic philosophy have emphasised, on the path to achieving relative truths, in addition to objective dialectical contradictions, there are also subjective formal-logical errors and mistakes that can only be distinguished from objective contradictions through practical verification.
