of what they fear. Binswanger proposed the first three of these dimensions from Heidegger's description of Umwelt and Mitwelt and his further notion of Eigenwelt. The fourth dimension was added by van Deurzen from Heidegger's description of a spiritual world (Überwelt) in Heidegger's later work. Physical dimension On the physical dimension (Umwelt), individuals relate to their environment and the givens of the natural world around them. This includes their attitude to the body they have, to the concrete surroundings they find themselves in, to the climate and the weather, to objects and material possessions, to the bodies of other people, their own bodily needs, to health and illness and their mortality. The struggle on this dimension is, in general terms, between the search for domination over the elements and natural law (as in technology, or in sports) and the need to accept the limitations of natural boundaries (as in ecology or old age). While people generally aim for security on this dimension (through health and wealth), much of life brings a gradual disillusionment and realization that such security can only be temporary. Recognizing limitations can deliver a significant release of tension. Social dimension On the social dimension (Mitwelt), individuals relate to others as they interact with the public world around them. This dimension includes their response to the culture they live in, as well as to the class and race they belong to (and also those they do not belong to). Attitudes here range from love to hate and from cooperation to competition. The dynamic contradictions can be understood concerning acceptance versus rejection or belonging versus isolation. Some people prefer to withdraw from the world of others as much as possible. Others blindly chase public acceptance by going along with the rules and fashions of the moment. Otherwise, they try to rise above these by becoming trendsetters themselves. By acquiring fame or other forms of power, individuals can attain dominance over others temporarily.

This dimension includes views about their character, their past experience and their future possibilities. Contradictions here are often experienced regarding personal strengths and weaknesses. People search for a sense of identity, a feeling of being substantial and having a self. But inevitably many events will confront
