Education, in like manner engrafts a new man on the native stock, & improves what in his nature was vicious & perverse, into qualities of virtue and social worth; and it cannot be but that each generation succeeding to the knowledge acquired by all those who preceded it
This idea is perfectly neoclassical, which is why one can see that Jefferson stated this claim about the purpose of education in his report about the founding of the nation's next great university. Education as stated by Jefferson creates a new person out of the savage that he once was into a righteous person. The idea that education changes the nature of the person is not something I necessarily agree with as some of the most vicious people in history were well educated. Take a modern example someone such as Richard Spencer one of the leaders in the alt-right he is highly educated and even attended UVA but still remains vicious. However, it should be noted that usually the qualities of virtue and social worth are taught to a person when they come to university and they usually leave with greater virtue and social worth, it is just not always the case.
