Estado da Arte (translated as State of the Art) is a culture, arts, and ideas magazine hosted on the portal of the prominent Brazilian newspaper O Estado de S. Paulo. As a contributing writer, I have crafted essays that delve into both Brazilian and international politics. The articles were originally composed in Portuguese, but below you can also find links to English translations.

Democracia: qual?
Democracy. But which?
Democracy as is a much less obvious idea than it may seem at first glance.
