Do not bite at the bait of pleasure till you know there is no hook beneath it. - Thomas Jefferson

Lipscomb, Andrew A. and Albert Ellery Bergh, eds. The Writings Of Thomas Jefferson 19 vol. (1907) not as complete nor as accurate as Boyd edition, but covers TJ from 1801 to his death. It is out of copyright, and so is online free.

Your favour of July 31, was duly received, and was read with peculiar pleasure. The sentiments breathed through the whole do honor to both the head and heart of the writer.

The love of justice and the love of country plead equally the cause of these people, and it is a moral reproach to us that they should have pleaded it so long in vain, and should have produced not a single effort, nay I fear not much serious willingness to relieve them & ourselves from our present condition of moral & political reprobation.
