For the first time in human history, our inactions cause far more harm to others than our actions ever could.

“A refreshing and necessary reminder on our ability…to help those in need.” — Moby

When we think about whether we are good people leading a good life, we usually think about actions. Bad people do bad things that hurt others. Good people do good things that help others, and they avoid doing bad things. Simple.

But while our actions certainly have consequences, today our inactions have far greater and far graver consequences. Bad actions can result in the suffering of a few or several dozen others; inaction can result in the extreme misery of thousands.

It wasn’t always this way. For nearly our entire history as a species, we lived in small groups with minimal resources, leaving our ability to help others limited and the consequences of inaction modest. It is not so today. Thanks to massive global populations, huge wealth disparities, and modern technologies, the average person now has more power to improve the lives of others than nearly anyone who has ever lived. But the flip side of that great power is the dizzyingly high cost of inaction, in which lives can hang in the balance with each dollar and hour of time we spend.

This is a book about what we don’t do. It’s about our failures to act and the suffering others endure as a result. It’s also about the incredible good that can be achieved when we cultivate an internal drive to do more.
