The concept of truth, the construction of narrative and the use of metaphor are tools used in the development and reinforcement of reality concepts. I explore the basic functions of these tools and the imperatives which inform their use. We tend to think of truth as something innate or inherent about our world when in fact even a very brief look at the history of humanity reveals truth as consistently changing to support changing criteria, contexts, needs and uses. As a concept it functions best if we agree to overlook its ever-changing nature. Whatever current ‘truth’ we are entertaining is always to be considered the ultimate and final version. By committing in this way we can fully institute and enjoy the benefits of our beliefs. We only find, by virtue of a full ideological commitment, the wanted psychological, spiritual and emotional comfort in the concept of a permanent, fixed and dependable reality.
