It is because only the popular masses require the rights to live in an independent and creative way free from all fetters of nature and society, that is, the independent rights. It is also because they have the strength to satisfy such requirement.

The rights not raised by the popular masses’ requirement and acquired by the popular masses’ struggle, are not the genuine ones.
