ABSTRACT
The power, flexibility, and creativity that language has given therapists is amazing. Human language exerts an enormous degree of control over our behaviour, and as we mature, we increasingly engage with our environment, not directly as it is, but through the filter of what our language and cognition tell us it is. Humans have many physical disadvantages. We cannot fly, breathe underwater, or bear extremes of temperature, and our bodies are relatively frail. However, our ability to communicate, band together, and organise has given us an incredible evolutionary advantage. It is said that around 200 species of large mammals have walked the Earth at some point, and that humans are responsible for the extinction of around half of them.
