The essays in this volume analyze three aspects of the history of the Left and Marxism in Latin America: first, the need to discuss the "changing times" in the 21 century and its many and varied ingredients as part of a complex history of intellectual practices and policy proposals that have played for more than a century, the aspirations of broad social changes in Latin American sectors. Second, the acclimatization of Marxism in Latin America as part of a series of discussions with other intellectual movements and at the same time, within a process of intellectual production conditioned by political and institutional factors. And third, the construction of certain views on the historical past as a linchpin of the various policy proposals of the left in Latin America. Together, the texts included in this book contribute to enrich the debates around the relationship between history and politics but also, somehow, to imagine scenarios of growing democracy, justice, and equality in the region.
