Lera Boroditsky's findings about how our language decides how we think about things is a captivating read. I think this research supports my notion that we will require a common world language to be able to truly communicate as equals, and to be able to progress as a peaceful species. She comes with many examples on how the differences affect fundamental things in our lives. I did not actually know that Russians think of death as a woman, but it explains a lot :)
