Just as there are physiological needs like food, movement, sleep and nerve supply, there are also mental requirements like a philosophy, self-esteem, vision, purpose and strategy.
We know thought is required for an optimal life because, in order to thrive in this world, we must learn. Take, for example, our physiology: though much of the body runs automatically, we must ensure the required needs are met in order for the “autopilot” to optimize its expression – it’s thinking that delivers. Food added into the body will be broken down and utilized as nutrients to the best of the body’s ability – but it is thought that brings it to the mouth.
In order to survive in the world you must learn, and to gain knowledge you must think. This makes thinking a primary human necessity for life and a fundamental By Design concept.
