This volume is the result of work that have maintained the compilers at the teams in their respective chairs of philosophy at the universities of Barcelona (Manuel Cruz) and Buenos Aires (Daniel Brauer), but also of years of collaboration between the two professorships. On the other hand, shows some of the main papers (reworked for this book) that took place in the International Congress in Buenos Aires in October 2000. The result can offer a broad overview of the main lines of research and issues and problems surrounding the historical knowledge and assumptions. Besides its academic value, the selected texts and Brauer Cross aims to provide elements for a better understanding of the past and thus a greater understanding of the present or in the words of the compilers of "our historical condition." The understanding of the past contains texts by Daniel Brauer, Manuel Cruz, Hayden White, Herbert Schnädelbach, Carla Cordua, Belvedres Rosa, Cecilia Macon, Veronica Tozzi, Maria Ines Mudrovcic, Fina Birulés, Mirko Wischke, Concha Roldán, Martin Sisto, Rolf-Peter Hortsmann, Elías José Palti, Cirilo Flórez, Chris Lorenz, Helmut Galle and Naihat Francisco.
