This chapter aligns scientific and pre-philosophical angles on history with various reflective and methodological considerations. The past, a philosophical puzzle at the best of times, presents itself to us in many ways and at many different scales. If we abandon ideas of providence or progress for more naturalism we are left with numerous often incommensurable stories. And our inescapable performative interest we have in such accounts impacts our understanding of the present age and our arguably dark future. We draw here on phenomenological, hermeneutic, and deconstructive critique to articulate a provisional temporal phronesis by which to address the challenges of Deep Time. This brings to the fore such notions as irreversibility, fatal delay, structural inertia, uneven development, tipping points, time unimaginable, multiple strands, and aporetic time. Every age raises deep philosophical questions in its own way. War, freedom, justice, sexual difference have all had their day, but today the spectacle of anthropogenic climate change presses philosophy to the limit. Agency, responsibility, time, history, nature, earth, life, science, even truth—are not only live issues, they are becoming perspicuously mortal concerns. How to deal with the passions aroused by our situation, which both drive and block an adequate response to it?
