Both in Polish and international literature Duns Scotus’ ethical thought has had a number of conflicting interpretations. The article presents the main elements of Duns Scotus’ ethical thought. The quaestions it tries to answer are the following: a) is Scotus’ ethics voluntaristic; b) if so, what type of voluntarism can one attribute to Scotus. Finding Scotus’ ethics moderately voluntaristic I distinguish and characterize three types of voluntarism that could be attributed to Scotus: psychological voluntarism (Duns finds the will more perfect (...) than the intellect as its acts are more perfect); theological voluntarism (Duns takes the Commandments of the first table to be obligatory in a stronger way than the Commandments of the second table), causal voluntarism (the will is taken to be the primary cause of free action, non determined even by the most perfect good).
