This thesis investigates the role of practical activity in the union of the soul and God in Meister Eckhart. Since Eckhart’s attitude toward temporal works is highly inconsistent, the thesis begins by examining the complex and intimate relationship between God and the temporal order in Eckhart’s discussions of creation in principio. Next it considers the creation of man and how he, through the natural function of the intellect interacting with the created order, is transformed into the image of God. Finally it examines the relationship between the intellectual and practical acts and considers the possibility of a union between God and the soul which takes place in practical activity in Eckhart’s thought. Throughout, the thesis makes reference to Eckhart’s creative use of the term indistinctum (indistinct) and its Middle High German equivalents with respect to God, the soul, and the union between the two.
