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.
Is there not in every human soul a primitive spark, a divine element, incorruptible in this world and immortal in the next, which can be developed by goodness, kindled, lit up, and made to radiate, and which evil can never entirely extinguish.
What we experience in dreams - assuming that we experience it often - belongs in the end just as much to the over-all economy of our soul as anything experienced "actually": we are richer or poorer on account of it.
You do not settle whether an argument is justified by merely showing that it is of some use. The distinction is not between useful and useless experiments but between barbarous and civilized behaviour. Vivisection is a social evil because if it advances human knowledge, it does so at the expense of human character.
When, however, you have an enemy, then do not requite him good for evil: for that would shame him. Instead, prove that he did some good for you. And rather be angry than put to shame! And when you are cursed, I do not like it that you want to bless. Rather curse a little also! And if you are done a great injustice, then quickly add five small ones. Hideous to behold is he who is obsessed with an injustice.
You are good when you are one with yourself. Yet when you are not one with yourself you are not evil. For a divided house is not a den of thieves; it is only a divided house. And a ship without rudder may wander aimlessly among perilous isles yet sink not to the bottom.

Boredom is an evil that is not to be estimated lightly. It can come in the end to real despair. The public authority takes precautions against it everywhere, as against other universal calamities.
