This text explores the profound ontological relationship between life and truth, defining the essence of life through a subject's active orientation toward the future. The author argues that life is not a passive state but a dynamic process that cannot be understood independently of the concept of truth. A subject is considered alive only as long as it maintains activity, the ultimate source of which is not the subject itself, but truth acting through it. The vitality of the subject is thus directly contingent upon whether truth utilizes it as an instrument to realize its own purposes and objectives. It is this relationship with truth that animates the subject and provides its existential grounding. Once the subject is left to its own devices and truth no longer manifests through it, its activity irreversibly ceases, leading to its metaphorical death. The text presents a philosophical conception of subjectivity where human existence is defined by its openness and responsiveness to a higher principle, which serves as the only genuine source of creative power and future-oriented movement.
