"Every second is of infinite value"

"They travel with a constant companion, autumn."

"Who is the wisest man? He who neither knows or wishes for anything else than what happens."

"This is the highest wisdom that I own; freedom and life are earned by those alone who conquer them each day anew."

"All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, till they take root in our personal experience."

"Wisdom is only found in truth."

"Whatever you cannot understand, you cannot possess."
