He in a very indirect way appeals to the readers emotions through the use of charged words. For example:
1-The first charged word Jefferson makes use of is liberty when he takes notice that all men deserve “life, liberty and the pursuit of happiness” (142).
2- A word with strong connotations is justice when he writes: “We have appealed to their native justice” (144)
3- Honor is the final charged word Jefferson uses when he declares the signers of the Declaration “pledge to each other our lives, our fortunes and our sacred honor” (144)
