Abstract

Gehlen's core idea in Man is that humans have unique properties which distinguish them from all other species: 1. world-openness, a concept originally coined by Max Scheler, which describes the ability of humans to adapt to various environments (as contrasted with animals, which can only survive in environments which match their evolutionary specialisation). This gives us 2. the ability to shape our environment according to our intentions, and it comprises a view of language as a way of acting (Gehlen was one of the first proponents of speech act theory), Human beings are also marked 3. by an excess of impulses and by 4. the ability of self-control. These properties allow us (again in contrast to all other animals) 5. to create our own (for example cultural) environments. Gehlen's philosophy has influenced many contemporary German thinkers in a range of disciplines, including Peter L. Berger, Thomas Luckmann and Niklas Luhmann in sociology, and Hans Blumenberg in philosophy.
