“I advise you to apply to all those whom you know will give something; next, to those whom you are uncertain whether they will give any thing or not, and show them the list of those who have given; and, lastly, do not neglect those who you are sure will give nothing, for in some of them you may be mistaken.”

“Slavery is such an atrocious debasement of human nature, that its very extirpation, if not performed with solicitous care, may sometimes open a source of serious evils. The unhappy man who has been treated as a brute animal, too frequently sinks beneath the common standard of the human species. The galling chains, that bind his body, do also fetter his intellectual faculties, and impair the social affections of his heart… To instruct, to advise, to qualify those, who have been restored to freedom, for the exercise and enjoyment of civil liberty… and to procure for their children an education calculated for their future situation in life; these are the great outlines of the annexed plan, which we have adopted.[For the Pennsylvania Society for Promoting the Abolition of Slavery, 1789]”
