Can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are of the gift of God? That they are not to be violated but with his wrath? Indeed, I tremble for my country when I reflect that God is just; that his justice cannot sleep forever; that considering numbers, nature and natural means only, a revolution of the wheel of fortune, an exchange of situation is among possible events; that it may become probable by supernatural interference! The Almighty has no attribute which can take side with us in such a contest.[67] With the morals of the people, their industry also is destroyed. For in a warm climate, no man will labor for himself who can make another labor for him. This is so true that of the proprietors of slaves a very small proportion indeed are ever seen to labor.[68] It is impossible to be temperate and to pursue this subject through the various considerations of policy, or morals, of history, natural and civil. We must be contented to hope they will force their way into every one's mind.... The way, I hope, is preparing, under the auspices of heaven, for a total emancipation, and that this is disposed, in the order of events, to be with the consent of the masters, rather than by their extirpation.[69] IV During the early part of Jefferson's public career he did not have a good opinion of the Negro and his possibilities. This is his attitude as expressed in his _Notes on Virginia_ in 1782, whenever he referred to the Negro. Ignorant of the fact that science shows that no race is superior to another, Jefferson considered the blacks inferior to the Indians, believed that they lacked literary ability, the finer senses of other races and although exhibiting a little aptitude in music were both physically and mentally inferior to the whites. It will probably be asked, why not retain and incorporate the blacks into the State, and thus save the expense of supplying by importation of white settlers, the vacancies they will leave? Deep-rooted prejudices entertained by the whites; ten thousand recollections, by the blacks, of the injuries they have sustained; new provocations; the real distinctions which nature has made; and many other circumstances will divide us into parties, and produce convulsions, which will probably never end but in the extermination of the one or the other race.[70]
