This text presents a philosophical critique of the concept of an infinite past of the universe. The author argues that the past exists as such only when it is someone's past—that is, when a subject or entity connects with or reacts to it. Since no entity possesses the capacity to respond to an infinite past, it follows that nothing can truly have one. For the universe as a whole, an infinite past would require either an improbable, infinite capacity for self-reaction or a fragmentation into disconnected, internally limited cycles that repeat without mutual continuity. In such a pluralized universe, individual cycles would be temporally incommensurable and independent of one another. The author suggests that maintaining the idea of infinite time alongside a requirement for universal continuity leads to a fundamental contradiction with the concepts of progress and evolution. Ultimately, the document challenges the possibility of an infinite, linear past within a coherent, developing cosmos.
