Quote by Kant, Immanuel

"Act only according to that maxim whereby you can at the same time will that it should become a universal law."

"Sapere aude! Dare to know! Have the courage to use your own understanding."

"Two things awe me most: the starry sky above and the moral law within."

"I am never content with myself in relation to my knowledge and virtue."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
