恶
In the actual world， a very great deal of the evil that is done does not spring from evil motives.
To know good and evil is not enough； one must also do them.
Good can exist without evil， whereas evil cannot exist without good.
The peculiar evil of silencing the expression of an opinion is that it is robbing the human race； posterity as well as the existing generation； those who dissent from the opinion， still more than those who hold it.
