According to Wikipedia, "Reason is an American libertarian monthly magazine published by the Reason Foundation."
Reason covers the news from a libertarian perspective. Although there is much variation among libertarian beliefs, libertarians are commonly described as socially liberal and fiscally conservative. Libertarians uphold liberty as a core principle and seek to maximize individual choice and voluntary association, with minimal state intervention in private decisionmaking.
Reason is the monthly print magazine of "free minds and free markets." It covers politics, culture, and ideas through a provocative mix of news, analysis, commentary, and reviews. Reason provides a refreshing alternative to right-wing and left-wing opinion magazines by making a principled case for liberty and individual choice in all areas of human activity. Reason Online is updated daily with articles and columns on current developments in politics and culture. It also contains the full text of past issues of the print edition of Reason. Reason Online is entirely free. Reason and Reason Online are editorially independent publications of the Reason Foundation, a national, non-profit research and educational organization.
