"Youth is an unpleasant period; for then..." - Quote by Friedrich Nietzsche

“Prejudice of the learned. - The learned judge correctly that people of all ages have believed they know what is good and evil, praise- and blameworthy. But it is a prejudice of the learned that we now know better than any other age.”

“We are unknown to ourselves, we men of knowledge - and with good reason. We have never sought ourselves - how could it happen that we should ever find ourselves? It has rightly been said: "Where your treasure is, there will your heart be also"; our treasure is where the beehives of our knowledge are.”

“Rational thought is interpretation according to a scheme which we cannot escape.”

“What made us dream that he could comb gray hair?”

“Being young is beautiful, but being old is comfortable.”

“The future promise of any nation can be directly measured by the present prospects of its youth.”

“The first forty years of our life give the text, the next thirty furnish the commentary upon it, which enables us rightly to understand the true meaning and connection of the text with its moral and its beauties.”

“In childhood be modest, in youth temperate, in adulthood just, and in old age prudent.”

“I do know that when I am 60, I should be attempting to achieve different personal goals than those which had priority at age 20.”
