The document posits that a fundamental principle of philosophy is a profound distrust of everything that appears self-evident. Rationality must not rest upon unquestioned premises but requires continuous critical re-examination. The author argues that basing rational theories on self-evident assumptions is unacceptable in basic research, as every self-evidence is grounded in hidden foundations that must be uncovered. Philosophy's task is to identify these assumptions and verify their validity in new contexts, where no single context holds a privileged position. Internal coherence alone is insufficient for validation; concepts and frameworks must be tested through their application in concrete life practice. Concepts are not derived directly from experience but are constituted within the environment of "LOGOS" as relatively a priori constructs. Ultimately, the goal of thought strategies should be the comprehensive understanding of the world and the self, rather than the mere creation of internally consistent systems. This process involves methodical tactics and strategic thinking to achieve deeper existential insight.
