What, but education, has advanced us beyond the condition of our indigenous neighbours? and what chains them to their present state of barbarism & wretchedness, but a besotted veneration for the supposed supe[r]lative wisdom of their fathers and the preposterous idea that they are to look backward for better things and not forward, longing, as it should seem, to return to the days of eating acorns and roots rather than indulge in the degeneracies of civilization.
The sentence here clearly represents the thoughts of the average man of the time towards any other civilization (or lack thereof). The majority of Americans at the time believed that their civilization was far superior to the Native Americans as Jefferson speaks of here. Here, Jefferson states that it is the formal education that sets them apart and makes the "indigenous neighbors" barbarous and less-civilized. I enjoy the fact that Jefferson values education so much to the point that he finds it such a separating factor; however, it is clear that he is degrading and looking down upon the natives simply because they do not practice the same customs or traditions or have remotely the same culture. With this all being said, it cane said that today, there are many people who still see cultures who are different from their own as inferior.
