This book proposes a developmental theory of human mind as a basic interaction system of meaning making elements - so called dualities - progressing in dialectical shifts towards higher self-awareness. It elaborates on why this system has developed evolutionary, how it develops in the life courses of humans in modern societies and what hampers and promotes its progression to meet contemporary and future societal challenges.

He has been engaged for several decades in research as well as in methodological and theoretical development focusing mainly people`s action and development conditions in important life course and work life transitions.
