The very shaping of history now outpaces the ability of men to orient themselves in accordance with cherished values. And which values? Even when they do not panic, men often sense that older ways of feeling and thinking have collapsed and that newer beginnings are ambiguous to the point of moral stasis.

Human activities have become a significant force shaping Earth's climate.

History is not the past. It is the present. We carry our history with us. We are our history.
