Bohumil Hrabal
“اغلب فکر می کنیم این که به یاد کسی هستیم منتی است بر گردن آن شخص. غافل از آن که اگر به یاد کسی هستیم این هنر اوست نه ما." به یاد ماندنی بودن" بسیار مهم تر از به یاد بودن است”
Bohumil Hrabal

“This statement is not provable.” Think about it for a minute. It’s a strange statement, since it talks about itself—in fact, it asserts that it is not provable. Let’s call this statement “Statement A.” Now, suppose Statement A could indeed be proved. But then it would be false (since it states that it cannot be proved). That would mean a false statement could be proved—arithmetic would be inconsistent. Okay, let’s assume the opposite, that Statement A cannot be proved. That would mean that Statement A is true (because it asserts that it cannot be proved), but then there is a true statement that cannot be proved—arithmetic would be incomplete. Ergo, arithmetic is either inconsistent or incomplete.”
Melanie Mitchell, Complexity: A Guided Tour

این جهان کوهست و فعل ما ندا
