„Translation: Alas! So there is no escape from the question. Not for me, not for anyone! Then life is just breathing or running behind infinite number of questions? And then, what question is really? And what answer is too? This too a question. I observe the question mark carefully. And Eureka! I didn't know that my answer was encrypted and hidden in that symbol of a question mark. The dot below the curved stroke in a question mark symbolizes Zero as the question's answer itself, I never knew. Punctuation marks are so carefully crafted, I never knew!“
— P. L. Deshpande Marathi writer, humourist, actor, dramatist 1919 - 2000
citation needed झाले ! म्हणजे प्रश्नातून सुटका नाही. माझीच नव्हे, कुणाचीच नाही! मग जगणे म्हणजे नुसते श्वासोच्छ्वास घेणे की लक्ष लक्ष प्रश्नांच्या उत्तरांमागून धावणे? शेवटी प्रश्न म्हणजे तरी काय आणि उत्तर म्हणजे तरी काय? हादेखील एक प्रश्नच. मी त्या प्रश्नचिन्हाकडेच निरखून पाहतो. आणि युरेका! त्या प्रश्नचिन्हातच माझे उत्तर कसल्याशा सांकेतिक भाषेत दडवले आहे हे मला ठाऊक नव्हते. प्रश्नचिन्हाच्या त्या आकड्याखालीच शून्य हे त्याचे उत्तरही असते. विरामिचन्हे इतकी विचारपूर्वक बनवली असतील याची मला कल्पना नव्हती!
„During another examination the question paper read, ‘do any six questions, all questions carry equal marks’. But I attempted more than six questions and wrote for the examiner, “examine any six questions, all questions carry equal marks.“

„Maugham then offers the greatest advice anyone could give to a young author: "At the end of an interrogation sentence, place a question mark. You'd be surprised how effective it can be.“

„Any man who can drive safely while kissing a pretty girl is simply not giving the kiss the attention it deserves“
— Albert Einstein German-born physicist and founder of the theory of relativity 1879 - 1955
Found anonymously in newspaper columns from the early 1920s http://quoteinvestigator.com/2015/12/31/kiss. Originally presented in dialogue format https://www.newspapers.com/clip/5219841/safety_first/: "Dorcas—”Do you ever allow a man to kiss you when you’re out motoring with him? Philippa—"Never, if a man can drive safely while kissing me he’s not giving the kiss the attention it deserves." It does not seem to have been attributed to Einstein until the 1990s (e.g. here https://groups.google.com/forum/message/raw?msg=alt.freemasonry/YILn0A-U_WM/f1Grm2akU-4J).
„Confusion exists in the map, not in the territory. Unanswerable questions do not mark places where magic enters the universe. They mark places where your mind runs skew to reality.“
— Eliezer Yudkowsky American blogger, writer, and artificial intelligence researcher 1979
Context: Mystery exists in the mind, not in reality. If I am ignorant about a phenomenon, that is a fact about my state of mind, not a fact about the phenomenon itself. All the more so, if it seems like no possible answer can exist: Confusion exists in the map, not in the territory. Unanswerable questions do not mark places where magic enters the universe. They mark places where your mind runs skew to reality. A comment on Wrong Questions http://lesswrong.com/lw/og/wrong_questions/ (March 2008)
„In the Cambridge mathematical tripods, they said, ’do six questions. Complete questions carry proportionately more marks than an equal number of fragments. Till you attempt half of the questions you won’t get full credit’. Upon declaration of result I found that I had scored 110 out of hundred in one paper, 140 in another and likewise in all the rest. I was confused. So my tutor explained to me that although they write ‘do six questions’, you can attempt as many as you want. They award you marks for whatever questions you answer correctly and the ranks are on basis of the score.“

„In all affairs it's a healthy thing now and then to hang a question mark on the things you have long taken for granted.“

„There are times when God leaves huge question marks as tools in our lives to stretch our our faith.“
