“The free, unhampered exchange of ideas and scientific conclusions is necessary for the sound development of science, as it is in all spheres of cultural life.”
Science is the unfettered pursuit of pure knowledge. An ideal that can never be fully realized as even the most open human mind – the mind of an Einstein – carries with it the inevitable traces of personal bias. But we can maintain that ideal nonetheless.
Filtering science through moralistic dogma, political agenda, or simple delusion dooms what we would call “science”, and therefore the pursuit of knowledge, to ultimate failure. Knowledge is not advanced and human progress is diminished.
If we are not willing to follow in the path that knowledge takes us, we have no choice but to turn back toward the cave from which we came.
