“Knowledge in the head and virtue in the heart, time devoted to study or business, instead of show and pleasure, are the way to be useful and consequently happy.”

“I cannot think it either Vanity or Virtue to acknowledge, that the Acquisition and communication of Knowledge, are the sole Entertainment of my Life”

“Now to what higher object, to what greater character, can any mortal aspire than to be possessed of all this knowledge, well digested and ready at command, to assist the feeble and friendless, to discountenance the haughty and lawless, to procure redress to wrongs, the advancement of rights, to assert and maintain liberty and virtue to discourage and abolish tyranny and vice.”

Our sons ought to study mathematics and philosophy, geography, natural history and naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry and porcelain.”

“It is not in the still calm of life, or the repose of a pacific station, that great characters are formed. The habits of a vigorous mind are formed in contending with difficulties.

When a mind is raised, and animated by scenes that engage the heart, then those qualities which would otherwise lay dormant, wake into life and form the character of the hero and the statesman.”
