The importation of foreigners into a country that has as many inhabitants as the present employments and provisions for subsistence will bear, will be in the end no increase of people, unless the new comers have more industry and frugality than the natives, and then they will provide more subsistence, and increase in the country; but they will gradually eat the natives out. Nor is it necessary to bring in foreigners to fill up any occasional vacancy in a country for such vacancy will soon be filled by natural generation.
Benjamin FranklinWithout freedom of thought, there can be no such thing as wisdom; and no such thing as public liberty without freedom of speech; which is the right of every man as far as by it he does not hurt or control the right of another; and this is the only check it ought to suffer and the only bounds it ought to know.... Whoever would overthrow the liberty of a nation must begin by subduing the freedom of speech, a thing terrible to traitors.
Benjamin Franklin
