Abstract
"...that the search for knowledge and understanding of the physical universe and of living things that inhabit it should be conducted under conditions of intellectual freedom, without religious, political, or ideological restrictions ... that inquiry and dissemination of ideas require that those so engaged be free to search where their inquiry leads ... without political censorship and without fear of retribution in consequence of unpopularity of their conclusions. Those who challenge existing theories must be protected from retaliatory reactions." (National Academy - Resolution 1976.)
