“In the last century [then the seventeenth century], Latin was the universal language of Europe. Correspondence among the learned, and indeed among merchants and men of business and the conversation of strangers and travellers, was generally carried on in that dead language. In the present century [then the eighteenth century], Latin has been generally laid aside, and French has been substituted in its place; but has not yet become universally established, and according to present appearances, it is not probable that it will. English is destined to be in the next and succeeding centuries, more generally the language of the world, than Latin was in the last, or French is in the present age.”
Anecdote about how our Founding Fathers were avid students of Latin
Our Founding Fathers were avid students of Greek and Latin. For example, over the years, John Adams wrote a number of letters to his future-president son John Quincy Adams. In 1781, specifically, John Adams once told his son: “You go on, I presume, with your Latin exercises: and I wish to hear of your beginning upon Sallust who is one of the most polished and perfect of the Roman historians, every period of whom, and I had almost said every syllable and every letter is worth studying.” (Source: Letter of 18 May 1781) In another letter, John Adams also told his son that “The writings of Cicero too, you should read in turn. When I speak of reading I dont mean holding a book in hand and dreaming over it— take your pen.—and make yourself master of every sentence.— By all means make yourself master of the Latin tongue and that immediately.” (Source: Letter of 4 October 1790) Thus, John Adams advised his son to “go on … with your Latin exercises,” and “By all means make yourself master of the Latin tongue and that immediately” (as cited above). Thus, John Adams must have considered the study of Latin to be valuable. More about his admiration for the Ancient Greek language here.
