“He was good at explaining how, for him, concepts of human rights grew out of science.

Science stresses independence of judgment, not conformity to the judgment of others. 3. “Science is egalitarian”; no one’s subjective view starts ahead of anyone else’s in the pursuit of objective truth. 4. Science needs a free flow of information, and cannot thrive in a system that restricts access to information. 5. Scientific truths, like human rights principles, are universal; they do not change when one crosses a political border.”
