Reading Schelling offers a central idea of ​​the work of the German idealist to lock a certain unity through the apparent diversity of his work. It also includes the great milestones of Schelling's thinking with the aim of improving and better understanding the understanding of his work. This introduction is a thread of Ariadna to be able to travel the complex and prolific philosophical trajectory of Schelling. This main nucleus has to do with the Schelling "philosopher of freedom" that has been rediscovered and revealed in recent times, especially thanks to the critical and specialized study that has revived the historical-critical edition of Schelling's complete works, of which the author of this book, Wilhem G. Jacobs, is co-editor. Experiencing the need to re-read Schelling in light of these findings, and the possibility of doing so by having key concepts at hand to understand the coherence of his philosophical trajectory are, by themselves, sufficient reasons to read this text. Reading Schelling will lead us to awaken the desire to return to dialogue with this philosopher, as well as to understand why it attracts so strongly the attention of researchers in recent times.
