Science is an enterprise that can only flourish if it puts the truth ahead of nationality, ethnicity, class and color.

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

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

Idealism is the highest form of reason.

A new sense of shared international responsibility is unmistakable in the voices of the United Nations and its agencies, and in the civil society of thousands of supra-national NGOs.

The eye searches for shapes. It searches for a beginning, a middle, and an end.

When, as we must often do, we fear science, we really fear ourselves. Human dignity is better served by embracing knowledge.
