Erasmus of Rotterdam came from an obscure background but, through remarkable perseverance, skill, and independent vision, became a powerful and controversial intellectual figure in Europe in the early sixteenth century. He was known for his vigorous opposition to war, intolerance, and hypocrisy, and at the same time for irony and subtlety that could confuse his friends as well as his opponents. His ideas about language, society, scholarship, and religion influenced the rise of the Reformation and had a huge impact on the humanities, and that influence continues today. This book shows how an independent textual scholar was able, by the power of the printing press and his wits, to attain both fame and notoriety. Drawing on the immense wealth of recent scholarship devoted to Erasmus, Erasmus of Rotterdam is the first English-language popular biography of this crucial thinker in twenty years.
