Billions & Billions
Carl Sagan's "Billions & Billions" is a collection of essays covering a wide variety of topics. The essays are grouped into three parts: "The Power and Beauty of Quantification", "What Are Conservatives Conserving?", and "Where Hearts and Minds Collide." I started reading the book some time ago and interspersed it with others so my recollection of the book as a whole is a little fuzzy. Some of the essays did feel dated as the facts and conditions presented have clearly changed, mostly for the better, since originally written.
I had originally picked up the book after reading an excerpt from the essay entitled "Abortion: Is It Possible to Be Both 'Pro-Life' and 'Pro-Choice'?" This along with most of the other essays in part three is a reason to read the book. The reasoned approach and insight brought to many of the subjects touched upon gives ample evidence to the impact he had on so many lives.
