Abstract
In my paper I try to reconstruct the core of Martin Luther’s and Erasmus of Rotterdam’s view on the question of free will on the basis of my analysis of Erasmus’ treatise De libero arbitrio diatribé sive collatio and Luther’s answer De servo arbitrio. I also examine the compatibility of their views, or rather the main reasons for their incompatibility. I analyse the problematic and adversarial moments of both of the great thinkers views, which I fi nd in the case of Martin Luther for example in the idea of all-doing God and in the view on the creation of the fi rst human, Adam; and in the case of Erasmus of Rotterdam for example in the question of merits and in the assertion that a spreading of the truth might be scandalous. Before presenting my conclusions I also deal with the diff erences in applied terminology and methodology of these two reform thinkers, which leads me to the question of the criterion of the truth. On the basis of these observationsI search for the key reasons for the disagreement between the two protagonists of this dispute and I evaluate the whole debate.
