After discussing the complexity and multi-dimensionality of human behaviour, the author defines the principles of biodynamics and goes on to describe experiments with animals. Their reactions often appear similar to human ones, both individually and socially.

Experimentally induced 'conflicts' in animals resulted in free-floating anxiety, phobias, psychosomatic dysfunctions, compulsions, aggression and regressions.

The neurotic patterns persisted indefinitely unless 'treated' along lines which are compared with human psychotherapeutic procedures. Similarly the effects of electroshock and drugs are compared with those in human beings.
