Human dignity is better served by embracing knowledge.

Science is a collection of stories, linking characters worthy of notice.

If we treasure our own experience and regard it as real, we must also treasure other people's experience.

At the heart of science lies discovery which involves a change in worldview. Discovery in science is possible only in societies which accord their citizens the freedom to pursue the truth where it may lead and which therefore have respect for different paths to that truth.

Some dreamers demand that scientists only discover things that can be used for good.

It takes a trained and discerning researcher to keep the goal in sight, and to detect evidence of the creeping progress toward it.

Authority in science exists to be questioned, since heresy is the spring from which new ideas flow.
