The magazine Análisis with this issue on ways of making history, intends to add and contribute in diferent forms to a debate of great academic importance, which not only concerns the ields of history or human sciences, but also concerns all exact sciences. The common debate in all the branches of human knowledge is about wondering at the time of formulating a research problem: On which topic is it necessary to inquire or write about? and from what theoretical or methodological point(s) of view is this best done. There are often attempts to answer both questions, on the one hand using the postulates by those authors regarded as “foundational” in a speciic science or knowledge, on the other hand, taking into account the issues of greater repercussions in the academy.
