Here's a quotation from a US President that both exemplifies and problematises masculinity:
“I am a warrior, so that my son may be a merchant, so that his son may be a poet.”
β John Quincy Adams
(Actually, having done some further research, the attribution to J.Q. Adams may be erroneous. It seems that his father, also President, John Adams, wrote the following to his wife:
"I must study Politicks and War that my sons may have liberty to study Mathematicks and Philosophy. My sons ought to study Mathematicks and Philosophy, Geography, natural History, Naval Architecture, navigation, Commerce, and Agriculture, in order to give their Children a right to study Painting, Poetry, Musick, Architecture, Statuary, Tapestry, and Porcelaine."
Letter to Abigail Adams, May 12, 1780)
