In recognizing that Wittgenstein denies that there is a mental state or mechanism of understanding that underlies the various manifestations of what we call "understanding," we should be careful to avoid two possible misreadings. The first reads Wittgenstein as a behaviorist, saying that there are no hidden mechanisms underlying different forms of behavior, and that the behavior itself (the various manifestations) is understanding. The second reads Wittgenstein as claiming we are mistaken to talk about understanding at all. Wittgenstein denies that understanding is a thing we can identify and talk about, whether it be a mental mechanism or certain forms of behavior. However, this move is meant to counteract attempts to turn "understanding" into a technical term and include it in our psychological vocabulary. Wittgenstein has no problem with talking about understanding in ordinary contexts.
