The Black Man

In this work, African American historian Joseph E. Hayne counters and refutes white racist theories of his era that denigrated Blacks through alleged "scientific evidence". Although lacking the scientific credentials held by his antagonists, Hayne discusses issues of race amalgamation and the idea that black persons are "Hamites" or descendants of Biblical Noah's son Ham.
