Monsieur, my son is twenty-two years old. If he had not become a Communist at twenty-two, I would have disowned him. If he is still a Communist at thirty, I will do it then.
Georges Clemenceau (1841–1929) French statesman, physician, journalist
(Attributed)
Response to someone who was alarmed about his son being a Communist, as attributed in Bennett Cerf, Try and Stop Me (1944).
This may be the source of the quote also attributed to Clemenceau, “Any man who is not a socialist at age twenty has no heart. Any man who is still a socialist at age forty has no head.” Later, George Seldes attributed to David Lloyd George: "A young man who isn’t a socialist hasn’t got a heart; an old man who is a socialist hasn’t got a head.” François Guizot in the mid-19th Century was said to have said, “Not to be a republican at twenty is proof of want of heart; to be one at thirty is proof of want of head.”
The earliest version of this comes from a public letter by Anselme Polycarpe Batbie (1828-1887), who attributed this to Edmund Burke: "Anyone who is not a republican at twenty casts doubt on the generosity of his soul; but he who, after thirty years, perseveres, casts doubt on the soundness of his mind. [Celui qui n’est pas républicain à vingt ans fait douter de la générosité de son âme; mais celui qui, après trente ans, persévère, fait douter de la rectitude de son esprit.]" This has not been found in Burke's writings.
Variants have also been attributed to Benjamin Disraeli, Dean Inge, George Bernard Shaw, Winston Churchill, Otto von Bismarck, and Bertrand Russell.
