Nobody wishes more than I do to see such proofs as you exhibit, that nature has given to our black brethren talents equal to those of the other colors of men, and that the appearance of a want of them is owing merely to the degraded condition of their existence, both in Africa and America.... I have taken the liberty of sending your Almanac to Monsieur de Condorcet, Secretary of the Academy of Sciences at Paris, and member of the Philanthropic Society, because I considered it as a document to which your color had a right for their justification against the doubts which have been entertained of them[83] Jefferson's letter to the Marquis de Condorcet presented Banneker's attainments as evidence of the mental capacity of Negroes. He said: We have now in the United States a Negro, the son of a black man born in Africa and a black woman born in the United States, who is a very respectable mathematician. I procured him to be employed under one of our chief directors in laying out the new Federal City on the Potomac and in the intervals of his leisure, while on that work, he made an almanac for the next year, which he sent me in his own handwriting, and which I enclose to you. I have seen very elegant solutions of geometrical problems by him. Add to this that he is a very worthy and respectable member of society. He is a free man. I shall be delighted to see these instances of moral eminence so multiplied as to prove that the want of talents observed in them, is merely the effect of their degraded condition, and not proceeding from any difference in the structure of the parts on which intellect depends[84] In a letter to Banneker himself concerning the achievements of this astronomer and mathematician, Jefferson said: Nobody wishes more ardently than I do to see a good system commenced for raising the condition both of their body and mind to what it ought to be, as fast as the imbecility of their present existence, and other circumstances which cannot be neglected, will admit.[85] A generation later he had, as this letter indicates, retained the opinion that the possibilities of the Negroes were not necessarily limited. To Henri Gregoire who had sent Jefferson a copy of his _Litterature des Negres_, he wrote:
