Is the rise of terrorism and violence justifiably traced to the teachings of Islam, or is this call to war a twisted interpretation of the true Muslim faith? Most of the world’s 1.5 billion Muslims are moderates who see Islamic terrorism as a violation of their sacred texts. Is it wrong to let a radical minority represent authentic Islam? Has fear blinded us to its lessons of tolerance and peace?

In the words of Blaise Pascal, mathematician and Catholic, “Men never do evil so completely and cheerfully as when they do it from a religious conviction.” Does religion breed intolerance, violence, and the promotion of medieval ideas? Or should we concede that overall, it has been a source for good, giving followers purpose, while encouraging morality and ethical behavior?

It was 1971 when President Richard Nixon declared a "war on drugs." $2.5 trillion dollars later, drug use is half of what it was 30 years ago, and thousands of offenders are successfully diverted to treatment instead of jail. And yet, 22 million Americans-9% of the population-still uses illegal drugs, and with the highest incarceration rate in the world, we continue to fill our prisons with drug offenders. Decimated families and communities are left in the wake. Is it time to legalize drugs or is this a war that we're winning?

If consciousness is just the workings of neurons and synapses, how do we explain the phenomenon of the near-death experience? By some accounts, about 3% of the U.S. population has had one: an out-of-body experience often characterized by remarkable visions and feelings of peace and joy, all while the physical body is close to death. To skeptics, there are more plausible, natural explanations, like oxygen deprivation. Is the prospect of an existence after death "real" and provable by science, or a construct of wishful thinking about our own mortality?
