“Man is a question mark . . . and it is a blessing—celebrate it. It is a blessing because only man is a question mark; no dog is, no tree is. The rose bush is beautiful but not as beautiful as man, and the moon is beautiful but not as beautiful as man—because they are unconscious. Only man is consciously on a quest. And how can you be on a quest if you don’t have a question mark in your being?”
― Osho, The secret of secrets

“He lives at Balbec?” crooned the Baron in a tone so far from interrogatory that it is regrettable that the written language does not possess a sign other than the question mark to end such apparently unquestioning remarks. It is true that such a sign would be of little use except to M. de Charlus.”
― Marcel Proust, Sodom and Gomorrah

“Life is not a period or a question mark. It’s an exclamation point.”
― Bashar

“Sentensi ni mkusanyiko wa maneno unaoanza na herufi kubwa na kuisha na alama ya kushangaa, kuuliza, au nukta. Sentensi bora ni fupi, angavu, sahihi, yenye mantiki, na kamilifu.”
― Enock Maregesi

“If the headline asks a question, try answering 'no'. Is This the True Face of Britain's Young? (Sensible reader: No.) Have We Found the Cure for AIDS? (No; or you wouldn't have put the question mark in.) Does This Map Provide the Key for Peace? (Probably not.) A headline with a question mark at the end means, in the vast majority of cases, that the story is tendentious or over-sold. It is often a scare story, or an attempt to elevate some run-of-the-mill piece of reporting into a national controversy and, preferably, a national panic. To a busy journalist hunting for real information a question mark means 'don't bother reading this bit'.”

“Sometimes, Life is a Question Mark ?”
― Biju Karakkonam, Nature and Wildlife Photographer

“Sometimes what separates the truth from one another is simply a question mark…”
