is logic universal?

A special issue of the journal Logica Universalis dedicated to the question "is logic universal?" has been released. http://www.springerlink.com/content/120443/?Content+Status=Accepted The authors have tried to answer the following questions: 1. Do all human beings have the same capacity of reasoning? Do men, women, children, Papuans, yuppies, reason in the same way? 2. Does reasoning evolve? Did human beings reason in the same way two centuries ago? In the future will human beings reason in the same way? Are computers changing our way of reasoning? Is a mathematical proof independent of time and culture? 3. Do we reason in different ways depending on the situation? Do we use the same logic for everyday life, in physics, and in questions to do with the economy? 4. Do the different systems of logic reflect the diversity of reasoning? 5. Is there any absolute true way of reasoning?
