Georg C. Lichtenberg

"We accumulate our opinions at an age when our understanding is at its weakest."

"Even truth needs to be clad in new garments if it is to appeal to a new age."

"We cannot remember too often that when we observe nature, and especially the ordering of nature, it is always ourselves alone we are observing."

"I cannot say whether things will get better if we change what I can say is they must change if they are to get better."

"Never undertake anything for which you wouldn't have the courage to ask the blessings of heaven."

"Much can be inferred about a man from his mistress: in her one beholds his weaknesses and his dreams."
