sanity

Sanity is how we can tell if a person is thinking and acting in a normal, healthy way, or if they are having trouble understanding reality. It means being able to see the world and react to it in a way that is reasonable. It means understanding that while people may think or do different things, those things all still fit within a normal way to think or act. Someone with sanity is usually able to manage their emotions, think clearly, and make good decisions.
