Humans, unlike all other creatures, need many years to evolve. When a baby is born, it hardly wants anything. But as it grows, its will to receive intensifies and evolves tremendously. When a new desire surfaces, it produces new needs, which the human being feels compelled to satisfy. To satisfy the new needs successfully, the brain evolves, as we begin to contemplate ways to satisfy the new desire. It follows that the brain’s intellectual and conceptual evolution is a consequence of the intensification of our desire to enjoy.
We can observe how this principle works by examining how we bring up our children. To help them grow, we create challenging games for them, and their desire to succeed in the game makes them contemplate new ways of coping, which facilitates their progress. From time to time we make the game more difficult to help them evolve and continue their progress. Hence, unless one feels that something is missing, one will never be able to evolve. It is only when we want something that we begin to activate our intellects and ponder how we can obtain our desires.
