Georges Clemenceau (1841–1929) French politician
On being told his son had joined the Communist Party, as quoted in Try and Stop Me (1944) by Bennet Cerf
A statement similar in theme has also been attributed to Clemenceau:
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.
As quoted in "Nice Guys Finish Seventh" : False Phrases, Spurious Sayings, and Familiar Misquotations (1992) by Ralph Keyes.
W. Gurney Benham in A Book of Quotations (1948) cites a statement by François Guizot as the earliest known expression of this general idea, stating that Clemenceau merely adapted the saying substituting socialiste for republicain:
N'être pas républicain à vingt ans est preuve d'un manque de cœur ; l'être après trente ans est preuve d'un manque de tête.
Not to be a republican at twenty is proof of want of heart; to be one at thirty is proof of want of head.
Variations on this general idea have also been attributed or misattributed to many others, most commonly Winston Churchill, who is not known to have actually made any similar statement.

George Woodcock (1912–1995) Canadian writer of political biography and history, an anarchist thinker, an essayist and literary critic
Prologue
Anarchism : A History of Libertarian Ideas and Movements (1962)
Context: Proudhon goes on to suggest that the real laws by which society functions have nothing to do with authority; they are not imposed from above, but stem from the nature of society itself. He sees the free emergence of such laws as the goal of social endeavour. … Proudhon conceiving a natural law of balance operating within society, rejects authority as an enemy and not a friend of order, and throws back at the authoritarians the accusations leveled at anarchists; in the process he adopts the title he hopes to have cleared of obloquy.
