“… for nightinggales - we know - can’t live on fairytales.”

“If there is a God and future life, there is truth and good, and man's highest happiness consists in striving to attain them. We must live, we must love, and we must believe that we live not only today on this scrap of earth, but have lived and shall live”

“without knowing who I am and why I’m here it is impossible to live. Yet I cannot know that and therefore I cannot live”

“We can know only that we know nothing. And that is the highest degree of human wisdom.”

“All we can know is that we know nothing. And that's the height of human wisdom.”

“The only thing that we know is that we know nothing, and that is the highest flight of human wisdom.”

“To know God and to live is one and the same thing. God is life.”
