Context: Josef Mitterer’s critique of Ludwig Wittgenstein’s concept of aspectual vision as elaborated in the second part of Philosophical Investigations and an attempt to develop a kind of non-dualistic “philosophy of systemic psychotherapy.” Problem: How can we ever say that we see something as some other thing when already seeing something is a kind of interpretative activity? Is everything we see an interpretation of an antecedent interpretation? Method: Analyzing and interpreting literature.Results: Wittgenstein, Rorty, and Mitterer develop their positions from a comparable kind of discomfort. The foundation of Mitterer’s critique, however, is completely different: his concept of non-dualism no longer only discusses problems resulting from aspectual vision or from the metaphor of a mirror in relation to objects but seeks to overcome the problems arising from the belief in a categorical difference between objects and the description of objects. Implications: If considered residually dualist in Mitterer’s perspective, aspectual vision in the sense of Wittgenstein is a controversial construction that needs further reflection.
