读书的目的是为了认识事物原理。为挑剔辩驳去读书是无聊。但也不可过于迷信书本。求知的目的不是为了吹嘘炫耀，而应该是为了寻找真理，启迪智慧。
Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider.
The molecules that mediate our sense of touch are the unsung heroes of our daily experiences.
痛苦是一种果实，上帝不会让它生长在无法承受的脆弱枝干上。
唯一能阻止你的人是你自己。
