This is the compelling story of the two biggest events in the evolution of ideas: the revolutions of Galileo and Darwin. The ideological shifts that resulted from their work were crucial not only to science. Their impact on society and culture has been equally decisive up to the current century. Mark Brake captures the adventure and excitement of these two scientists - one who overturned humanity's central place in the universe and and another who challenged the very notion of the origins of humankind. Their discoveries in a sense became "weapons of science," that challenged the long-held views of creation and human origins promoted by the Church for centuries. At a time when creationism and intelligent design are again in the news, this is a timely examination of the ways in which faith and science clash, and how the battle for "truth" is a perennial one.
