Nature has evolved human beings to require physical and emotional sustenance. The primary importance of our emotional needs has been shown by decades of research in neuroscience. The wiring between our limbic system (that part of the brain controlling emotionality) and our Cortex (that part of the brain controlling our cognitive processes) is such that the limbic system takes primacy over the cortex. In short emotion comes before thought. Psychologists, Joe Griffin and Ivan Tyrell from the Human Givens Institute have defined 9 major emotional needs as being a useful organizing principle for breaking down how to ensure the emotional health of people. These are:
If these needs are met in balance then it is impossible for the individual to suffer mental illness and indeed it is the seeking to meet these needs in balance, which is the underlying motivation of all human life. Knowing this then, it is flying in the face of reason for any social and political policy to be devised that does not seek to ensure these needs are being met in balance in society as a whole . To do anything other is simply a waste of time and money.
