In the "In Praise of Stupidity" Erasmus of Rotterdam makes a scathing critique of the vices of the society that he had to live using an immense erudition and a very fine sense of humor. Almost five hundred years after its first edition, his most popular work, which was already a true bestseller in its time, continues to maintain the freshness and value and the same meaning as when it was composed, revealing the ironic and scathing Erasmus , the disbeliever, the scourge of imbeciles of any gender and condition, but also the human, the condescending, the convinced optimist and the fervent believer.
