Para alguns, uma atitude crítica é infrutífera. Para Bertolt Brecht, dêem armas à crítica e estados podem ser destruídos.

On the critical attitude

The critical attitude
Strikes many people as unfruitful
That is because they find the state
Impervious to their criticism
But what in this case is an unfruitful attitude
Is merely a feeble attitude. Give criticism arms
And states can be demolished by it.

Canalising a river
Grafting a fruit tree
Educating a person
Transforming a state
These are instances of fruitful criticism
And at the same time instances of art.

Bertolt Brecht

(1898-1956)
