##### Abstract

We take a new look at the DeWitt equation, a defining equation for the
effective action functional in quantum field theory. We present a formal
solution to this equation, and discuss the equation in various contexts, and in
particular for models where it can be made completely well defined, such as the
Wess-Zumino model in two dimensions.
