But those who really love life would be happy as no one can be happy in the world as it is.

Context

“and as to beauty, what is more beautiful than the tiger, who owes his splendour to his fierceness? No, if the Lord should decide for your world, I fear we should all die of boredom.” “You might,” Buddha replies, “because you love pain, and your love of life is a sham. But those who really love life would be happy as no one can be happy in the world as it is.” For my part, I agree with Buddha as I have imagined him. But I do not know how to prove that he is right by any argument such as can be used in a mathematical or a scientific question. I dislike Nietzsche because he likes the contemplation of pain, because he erects conceit into a duty, because the men whom he most admires are conquerors, whose glory is cleverness in causing men to die.” source
