"The colony is the place where the project of a new humanity is to be tested, where the dream of a world without borders is to be realized, where the dream of a world without races is to be realized, where the dream of a world without nations is to be realized, where the dream of a world without classes is to be realized, where the dream of a world without genders is to be realized, where the dream of a world without religions is to be realized."
