The Search for Extraterrestrial Intelligence (SETI) is a research activitythat started in the late 1950s, predating the arrival of "Big History" and"Astrobiology" by several decades. Many elements first developed as part of theoriginal SETI narrative are now incorporated in both of these emergent fields.However, SETI still offers the widest possible perspective, since the topicnaturally leads us to consider not only the future development of our ownsociety but also the forward trajectories (and past histories) of many otherintelligent extraterrestrial forms. In this paper, I present a provocative viewof Big History, its rapid convergent focus on our own planet and society, itsoversimplified and incomplete view of events in cosmic history, and its limitedappreciation of how poorly we understand some aspects of the physical world.Astrophysicists are also not spared - in particular those who wish tounderstand the nature of the universe in "splendid isolation", only lookingoutwards and upwards. SETI can help re-expand all of our horizons but thediscovery of extraterrestrial intelligence may also require its ownpractitioners to abandon preconceptions of what constitutes intelligent,sentient, thinking minds.

Expanding World Views: Can SETI expand its own horizons and that of Big History too?
