The government is being urged to prevent organizations devoted to certain views on human nutrition from advocating a diet that includes large portions of uncooked meat, because eating uncooked meat can be very dangerous. However, this purported fact does not justify the government' s silencing the groups, for surely the government would not be justified in silencing a purely political group merely on the grounds that the policies the group advocates could be harmful to some members of society. The same should be true for silencing groups with certain views on human nutrition. Which one of the following principles most helps to justify the reasoning in the argument? ['The government ought to do whatever is in the best interest of society.', 'The government ought not to silence an opinion merely on the grounds that it could be harmful to disseminate the opinion.', 'The government should not silence any group for advocating a position that a significant proportion of society believes to be beneficial.', 'One ought to advocate a position only if one believes that it is true or would be beneficial.']
