Humanity's unprecedented technological capacity and concurrent existential risks reveal a critical lacuna in the philosophical tradition: the absence of a systematic framework for the long-term future. This article argues that formulating such a framework is the central ethical imperative of our era. To defend this thesis, it synthesizes the normative ethics of Hans Jonas and Derek Parfit with the analytical framework of Nick Bostrom's work on existential risk and longtermism. The analysis further addresses the ontological challenge posed by posthumanism to the human 'subject' and explores the functional role of a secular cosmic purpose in motivating long-term action. The paper's main contribution is the articulation of a synthetic research agenda for a prospective philosophy, one that integrates axiology, risk management, and ontology to guide humanity through its perilous technological adolescence.
