Human nature with all its infirmities and deprivation is still capable of great things. It is capable of attaining to degrees of wisdom and goodness, which we have reason to believe, appear as respectable in the estimation of superior intelligences. Education makes a greater difference between man and man, than nature has made between man and brute. The virtues and powers to which men may be trained, by early education and constant discipline, are truly sublime and astonishing. Isaac Newton and John Locke are examples of the deep sagacity which may be acquired by long habits of thinking and study.
