Famous quotes containing the words geological and/or period:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
“The easiest period in a crisis situation is actually the battle itself. The most difficult is the period of indecision—whether to fight or run away. And the most dangerous period is the aftermath. It is then, with all his resources spent and his guard down, that an individual must watch out for dulled reactions and faulty judgment.”
—Richard M. Nixon (1913–1995)
