We describe a way of handling reasoning with embedded context which is created by attitude verbs such as “think” and “believe”.

The meaning of the embedded sentence differs when it is extracted to the outside of the context of the attitude verb. Furthermore, some verbs enable certain kind of reasoning available within the context.

We use the multiple world mechanism of Uranus to implement the reasoning in embedded context.
