Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.
In many cultures it is customary to answer that God created the universe out of nothing. But this is mere temporizing. If we wish courageously to pursue the question, we must, of course ask next where God comes from? And if we decide this to be unanswerable, why not save a step and conclude that the universe has always existed?
An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.
Our species needs, and deserves, a citizenry with minds wide awake and a basic understanding of how the world works.
We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good.
You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe
I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking.
Atheism is more than just the knowledge that gods do not exist, and that religion is either a mistake or a fraud. Atheism is an attitude, a frame of mind that looks at the world objectively, fearlessly, always trying to understand all things as a part of nature.
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.
In the vastness of space and the immensity of time, it is my joy to share a planet and an epoch with Annie.
People are not stupid. They believe things for reasons. The last way for skeptics to get the attention of bright, curious, intelligent people is to belittle or condescend or to show arrogance toward their beliefs.
I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.
The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
