She had studied the universe all her life, but had overlooked its clearest message: For small creatures such as we the vastness is bearable only through love.

The way to find out about our place in the universe is by examining the universe and by examining ourselves - without preconceptions, with as unbiased a mind as we can muster.

Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science? ... No other human institution comes close.

You can get into a habit of thought in which you enjoy making fun of all those other people who don't see things as clearly as you do. We have to guard carefully against it.

The fact that so little of the findings of modern science is prefigured in Scripture to my mind casts further doubt on it divine inspiration.

There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths.

If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.
