Sam Harris argues that science can provide us with answers to moral questions and improve the quality of life for all humanity.

The question of right and wrong is often avoided in scientific discussions and, for many people, moral questions are left to religion to answer.

Questions about how we should live, raise our children, relate to friends, and treat our enemies are usually understood as subjective. They are dependent on cultural context.

We associate scientific facts with the fields of physics and mathematics. But they could also provide us with answers relevant to our well-being, happiness, and quality of life.

Sam Harris is a philosopher, neuroscientist, and author of five New York Times bestsellers.

In his books, Harris covers the topics of religion, moral philosophy, and neuroscience. He promotes the idea that science can help us live a better life.

In 2011's The Moral Landscape, Harris explores how scientific insights can determine human values and open up discussion on moral questions.
