excerpt from Wikipedia;
Binswanger argued that there are certain modes of existence. These modes of existence, he believed, allowed humans and non-human animals to be separated based on this concept. These modes include:
The Umwelt can apply to both non-human animals and humans. It is the relationship between the organism and its environment. However, according to Binswanger, non-human animal cannot possess the world as humans do. Non-human animals, "can neither design world nor open up world nor decide independently in and for a situation. As for humans, they do possess the world in the way that they can transcend their being above the level of non-human animals by, "climbing above it (the world) in care and of swinging beyond it in love."
The Mitwelt refers to the mode of existence involved in inter-species relations. Specifically, this mode applies mainly to humans in the sense of human interaction. It also refers to the "shared world" that we have with other people, i.e., viewing our lives according to our relationships with other humans.
The Eigenwelt refers to a person's own subjective experience, or the "self world." In other words, the Eigenwelt is the relationship that one has with themselves. This mode of existence is the most difficult to grasp because of its vague definition.
Weltanschauung (world-design) also applies to one's existence. An individual experiences the world through their own Weltanschauung, or world-design. A person's world-design is essentially how they view and open up to the world around them. This concept also is related to the modes of existence, as Binswanger points out:
"The world-design"..."is by no means confined to the environment to the world of things, or to the universe in general, but refers equally to the world of one's fellow men (Mitwelt) and to the self world (Eigenwelt)"
Two other concepts relate to Binswanger's view on existence, relating to the relationship between humans and the world or objects around them. Being-in-the-world is, "the normal and lawful interaction with the real-world environment that is considered primary to our way of existing in the world". It explains how we interact with our environment and the impact of that relationship. When "being-in-the-world," there are 3 general steps of assessment:
Being-beyond-the-world is the second of these concepts. This idea refers to how people can change their circumstances in the world by using free will. Similar to the concept of being-in-the-world, a person is transcended and is able to transform their world following their own motivations. Binswanger relates this idea to love, believing that, "it (love) takes us beyond the world of one's own self to the world of we-hood".
