Howard: We can't teach what we don't know

• Sociologically, race is classified as a social construction (i.e., not an irrefutable biological reality); that is, it is defined as an abstract notion, so to speak. Is this designation problematic for Howard; and, do you see any potential problems with this classification? Please explain. 
• What are “legitimizing myths”; and, what purpose do they serve (according to Howard)?
• Why does Howard consider the notion of meritocracy, as delineated in our distinctly Westernized, Eurocentric National ethos, to be mythical (pp. 37 of original text)? Please explain.
• Also on page 37 of the original text, Howard discusses what he terms “social arrangements of dominance”: please provide examples of said social arrangements, and, explain just how they fit into the definition that Howard provides.
