Explanation:

The excerpts for both literary pieces are-

It is therefore manifest, that something else ought yet to be done; and what is required, is evidently the incumbent duty of all men of enlightened understanding, and of every man that has any claim or affinity to the name of Christian, that the base treatment which the African Slaves undergo, ought to be abolished; and it is moreover evident, that the whole, or any part of that iniquitous traffic of slavery, can no where, or in any degree, be admitted, but among those who must eventually resign their own claim to any degree of sensibility and humanity, for that of barbarians.

( From Thoughts and Sentiments on the Evil of Slavery by Ottobah Cugoano)

I am sure you will applaud me for beseeching you to give one half hour's attention to slavery, as it is at this day practiced in our West Indies.—That subject, handled in your striking manner, would ease the yoke (perhaps) of many—but if only of one—Gracious God!—what a feast to a benevolent heart!—and, sure I am, you are an epicurean in acts of charity.—You, who are universally read, and as universally admired—you could not fail.

(From Letters of the Late Ignatius Sancho, An African. )

Both excerpts of the passages show that the authors of both hold the same view on the evil of slavery. Cugaono states that "the base treatment which the African Slaves undergo, ought to be abolished;" while Sancho also holds the same view "ease the yoke (perhaps) of many". Both individuals raise the issue of slavery and the need to break free of such practice, and bring about the freedom and liberty of the slaves and their future generations.
