Mahrer's audacious challenge to us to enunciate our foundational beliefs as psychotherapists raises interesting problems, at levels ranging from theepistemological to the personal. I reflect on these problems from a largely postmodern, constructivist perspective, and then accept his invitation to articulate some of my own core beliefs about psychotherapy. The result is a balanced consideration of the promise and pitfalls of Mahrer's method, which yields cautious optimism that it might invigorate our dialogue concerning the foundations of our discipline.
