An awareness is growing that humanity is living through a profound change of epoch. The consequences of this change sometimes take us by surprise. We must humbly recognize the inadequacy of our intellectual tools for measuring the effects of epochal change, understanding the present, and visualizing the future. Uncertainty is gaining ground in personal and social life. Uncertainty then sparks fear, provoking defensive reactions that turn our gaze toward an idealized past that never really existed. Fear tempts us to reject the newness of our time. –Arturo Sosa, S.J.
