Vidal’s (Found Sci, 2010 ) and Rottiers’s (Found Sci, 2010 ) commentaries on my (2010) paper raised a number of important issues about the possible future trajectory of evolution and its implications for humanity. My response emphasizes that despite the inherent uncertainty involved in extrapolating the trajectory of evolution into the far future, the possibilities it reveals nonetheless have significant strategic implications for what we do with our lives here and now, individually and collectively. One important implication is the replacement (...) of postmodern scepticism and relativism with an evolutionary grand narrative that can guide humanity to participate successfully in the future evolution of life in the universe.

A historically responsible agent is willing to be somehow in practical solidarity with all other actors with whom action is shared over time. The responsible idea of a most-inclusive history encompasses future occurrence together with all that has happened already. Despite our lack of control over future developments, we assess possible future ages as bright or dark and position ourselves as contributors to multigenerational endeavors that we hope will be long-term successes in themselves and part of a larger historical optimality. (...) Informed by the evolutionary sciences, a plausible modern envisioning of the future must include evolutionary innovations and surprises on a very long time scale. The historically responsible agent will therefore take seriously efforts like Olaf Stapledon’s Last and First Men to imagine the new powers and goals of our distantly posthuman future sharers in history.

The aim of this contribution is to critically examine the metaphysical presuppositions that prevail in (Stewart in Found Sci 15(4):395–409, 2010a ) answer to the question “are we in the midst of a developmental process?” as expressed in his statement “that humanity has discovered the trajectory of past evolution and can see how it is likely to continue in the future”.
