Michael Hampson's HEAD versus HEART rebuilds the enneagram on a single new foundation: the fundamental question of how we engage with the world around us. To this task we each bring three basic resources - 'head' and 'heart' and our 'gut reactions'. HEAD versus HEART is a study of the interaction of these three. From the very beginning HEAD versus HEART explains as it describes - something which has never been done for the enneagram before. It explains for the first time why the nine types emerge as they do - and why they interconnect according to the enneagram's distinctive irregular pattern of interconnecting lines. The material is logical and rational throughout - with clear links to cognitive, behavioural and even neurological psychology. All of this makes HEAD versus HEART the most accessible material ever produced on the enneagram - and the most important new work on the enneagram in thirty years.
