Our global community desperately needs overt awakening to an age of reason and faith. Reasonable Faith for a Post-Secular Age meets this need by interpreting faith not in terms of belief in propositions but in terms of living surrender to having been seized by agape for every Face, including one’s own. Virtually all faith traditions, from Buddhism to Humanism to Wiccan, are rooted in agape and therefore share considerable spiritual and ethical common ground (a truth long veiled). In contrast to ethically feckless secular rationality–over which a devastating, global social Darwinism currently runs roughshod–faith qua living surrender to agape grounds moral realism, awakens us to love for all creatures, and inspires struggles for justice. Inspired by the philosophy of Emmanuel Levinas and Christian spirituality, Greenway engages, on the one hand, intellectuals like Stanley Hauerwas, Richard Rorty, Gayatri Chakravorty Spivak, Jeffery Stout, Charles Taylor, and Bernard Williams, and, on the other, contemporary debates over consciousness, free will, evil, and metaethics. He details the character of secular rationality’s devastating scission from moral reality and clarifies the promise of understanding faith and spirituality in terms of agape.
