Throughout the history of philosophy, reflections on freedom in/of man have always been heated and fervent, to the point of deserving the attention of philosophers from all corners of the planet who analyse it from either an idealist or materialist perspective. In the debates of Western philosophers, rationalism with idealist characteristics (Hegel), as well as materialism from a materialist perspective (Marx), have looked deeply into freedom in/of man. In this debate on freedom, each in their own way argues that in order for man to live well in society, he must first of all own private property (Hegel) or satisfy his basic need through free labour (Marx). It is in this context that this book brings the reader a reflection on the problem of the possibility of Freedom in/of man in Hegel and Marx, with the aim of understanding the processes of liberation from a philosophical point of view, by first giving a historical description of the debates surrounding them from antiquity to the time of the authors. Using simple, contextual language, the book takes the reader on an ethical-philosophical journey that will enable them to situate themselves in the world.
