According to the document below, what is Frederick Douglass asking the philosophers and statesmen to do?

"We deem it a settled point that the destiny of the colored man is bound up with that of the white people of this country. ... We are here, and here we are likely to be. To imagine that we shall ever be eradicated is absurd and ridiculous. We can be remodified, changed, assimilated, but never extinguished. We repeat, therefore, that we are here; and that this is our country; and the question for the philosophers and statesmen of the land ought to be, what principles should dictate the policy of the action toward us? "
