This makes more sense if you read the Wikipedia bio:

“He called for the youth of Latin America to revert back to Greece-Roman habits of free thought and self enrichment.” It’s nice to have a monument for an essayist; gives those of us in the business some hope.

The page also notes that modern youth may know his name better from the Rodo amusement park. Some excellent pictures of the park and the rest of the city can be found here by a blogger in Uruguay.
