This volume addresses the main lines that the thought of the socialist left has taken over the last two centuries, particularly in Mexico. Due to the various modulations, concepts and strategies of struggle, a consistent continuity is perceived in the ideas, references, expectations and objectives of its intellectuals, whether they were utopians, romantic socialists, anarchists, Christian socialists, orthodox communists and dissidents that they took as their reflective core. the so-called “social question”, conceived in the 20th century as “social justice” and, contemporarily, as equity.

The crucial question was: how will socialist goals be achieved in a peripheral capitalist country? The answer will be found throughout the philosophical-biographical portraits that the author makes of each of the thinkers contained in this book. Furthermore, he will raise, together with them, new questions and lines of reflection for this immediate future that is foreseen.
