Animals (like the weasel) live in “necessity,” which means that their only goal in life is to survive. They don’t think about how they should live or what choices they should make like humans do. According to Dillard, we like to have options and resist the idea of “necessity.” We fight death—an inevitable force that we have no control over and yet ultimately surrender to it as it is the necessary end of our lives
This reminds me of pragmatic behavior. Despite the fact that we don't have much control over the course of events, the majority of us tend to live pragmatic lives. It might lead to someone falling into a lifelong trap since they only perceive specific outcomes or limited life options. There is no room for expansion.
