Social democracy embodies the political philosophy which comes closest to successfully meeting the criterion for being singled out and categorized among the other political philosophies as spiritually transcendent. Economist Henry George’s Land Value Taxation or “single tax” economic model also represents spiritual transcendence, although, unfortunately, Henry George’s eminently-logical economic model and thinking are irrationally treated as economic science anathema, denounced and/or strictly taboo inside the world’s so-called “leading” schools of economics. Leo Tolstoy (1828-1910) admired Henry George (1839-1897) for his clear arguments against land ownership and social inequality, considering George's ideas to be insightful and morally compelling. He believed that George's teachings were essential for understanding and addressing the injustices of society.
