To improve by reading, his morals and faculties.
I think it is important to note the correlation placed between morality and education. Academic education does not define a person's morality as there are examples of educated individuals who have shown questionable senses of morality and vice versa. This skewed ideology though allowed for the sense superiority over cultures whose education was not based on the European standards of learning. Due to the lack of literature in native North American or African cultures, Western forms of thought looked down upon individuals as they correlated the lack "education" with lack or morality and "civilization."
