I had to look up the author of this quote: H.L. Mencken upon seeing this sign at a Columbus, Ohio restaurant, as I recognized the name but not from where the passage came. Do you know? My little research had zero confirmed results.
Henry Louis “H. L.” Mencken, you might remember from early education, was associated with the “Monkey Trial” — he reported, satirically, on the Scopes trial (re: the teaching of evolution in schools). He was an American journalist and is regarded as one of the most influential American writers of the first half of the twentieth century.
His 1918 book “In Defense of Women” he discussed relationships with the opposite sex and observed the female sex as “wiser,” but whether he was truly a champion of women or a misogynist is debatable.
The entire quote:
Life without sex might be safer but it would be unbearably dull. It is the sex instinct which makes women seem beautiful, which they are once in a blue moon, and men seem wise and brave, which they never are at all. Throttle it, denaturalize it, take it away, and human existence would be reduced to the prosaic, laborious, boresome, imbecile level of life in an anthill. — Henry Louis Mencken
