Satisfaction is a peace of the soul, free from tension and unfulfilled desires, while
dissatisfaction acts like a thorn in the soul, people cannot rest.
Philipp Lersch (1898 - 1972) was a German philosopher and psychologist whose writings included many humanistic themes. He developed Kinesics (the interpretation of Body Language such as Facial Expression and Gesture) as part of the psychology of expression.
He proposed the concept of the Endotimic Base, which refers to bodily feelings, moods, and some emotional states, and it is important that these Vital Feelings are perceived as anchored in the body (see Vital Unconscious and Biocentric Principle).
