I have two; both of a philosophical nature. Often I see others who scoff at talking about the "philosophical implications" of some scientific theory, as though it is possible to do science without any regard to philosophical thought. Simply put, it is not. This next one is in German, so I also included various "popular" ways it is "translated" into English: Popular Translations: People are far too often willing to tell you their opinion, while prefacing their opinion with an admission that they actually don't know what they are talking about. "I don't know much about X, but I know this..." Ignorance is not a sin, as it is so often treated. Everyone is born into ignorance, but it is how we handle that ignorance that really defines our cognitive character.
