It has been calculated that the whites advance every year a mean distance of seventeen miles along the whole of this vast boundary. Obstacles such as an unproductive district, a lake, or an Indian nation are from time to time encountered. The advancing column then halts for a while; its two extremities curve round upon themselves, and as soon as they are reunited, they proceed onwards. This gradual and continuous progress of the European race towards the Rocky Mountains has the solemnity of a providential event; it is like a deluge of men rising unabatedly, and daily driven onwards by the hand of God.
—Alexis de Tocqueville, Democracy in America
Having done away with innate ideas, having altogether renounced the vanity of believing that we are always thinking, Locke proves that all our ideas come to us through the senses, examines our ideas both simple and complex, follows the human mind in all its operations, and shows the imperfections of all the languages spoken by man, and our constant abuse of terms. He comes at last to consider the extent, or rather the nothingness, of human knowledge.
