Let Divines, and Philosophers, Statesmen and Patriots unite their endeavours to renovate the Age, by impressing the Minds of Men with the importance of educating their little boys, and girls — of inculcating in the Minds of youth the fear, and Love of the Deity, and universal Phylanthropy; and in subordination to these great principles, the Love of their Country — of instructing them in the Art of self government, without which they never can act a wise part in the Government of Societys great, or small — in short of leading them in the Study, and Practice of the exalted Virtues of the Christian system.

Letter to John Adams (4 October 1790)
