An idea of ​​freedom that distinguishes between quantitative and qualitative, and defends the latter for being able to treat both individual and social freedoms.

The longing for freedom, questioned for a long time, is faced today with the pressing question of what freedom, and whose, must be encouraged when that of some collides with that of others? To face the new social and ecological challenges and fight against political and religious fundamentalism, a reorientation of liberalism is needed in which the quality - and not the quantity - of our freedoms is prioritized.

The present work builds a theory of freedom from a new terminology that leaves behind the classic dichotomy of political philosophy, "negative" freedom versus "positive" freedom, because it is incapable of responding to the new questions of linking moral, ecological sustainability, social co-management and cultural respect. In this way, Claus Dierksmeier traces a new architecture in liberal thought that allows the integration of the different variations that exist in the conception of freedom in the philosophical tradition.
