حريّتنا في الشك وُلدت من صراع ضدّ السلطة في الأيام الأولى للعلم. كان صراعًا عميقًا وشديدًا: دعونا نتساءل، نشكّ، ولا نكون على يقين. أرى أنّ من المهمّ ألّا ننسى هذا الصراع، فنخسر ربما ما كسبناه.

“Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question - to doubt - to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.”Richard P. Feynman — What Do You Care What Other People Think? (2011)
