ABSTRACT
Gerd Achenbach and Ad Hoogendijk are respectively German and Dutch contemporary philosophers who started establishing themselves as consultant philosophers (Achenbach 1984, 2002; Hoogendijk 1988) and led the way to a number of other developments all over the world. They proposed an alternative to psychotherapeutic culture by working purely in the arena of existential investigation with their ‘visitors’ (as they call their clients).
