After a recent thread that led to a discussion about the evolution of the mind, and what role our it plays in our lives, I thought it would be a good idea (unfortunately, I think any idea I have is good), to attempt to address the role of intelligence on the spiritual path.
The human brain has not evolved for over 50,000. The brain is the same today, in every way, as it was over 50,000 years ago. This is clearly due to the role intelligence has since played in our ability to survive. Evolution by natural selection, is survival of that which can reproduce. It’s not about being strong or intelligent, it’s about being able to reproduce. This would suggest that evolution could, and often does, select what we would consider in-competencies. For example, take a large population of humans who use contraceptives to avoid unwanted pregnancies. The more competent portion of the population, are naturally able to make the contraceptives work effectively for them, while the in-competent portion of the population would be less capable of making the contraceptives work for them, and thus, would give birth to offspring carrying the same genetic ‘in-competencies’.
This would also suggest that there would be no reason to believe that we would, in our future, every become a more intelligent species to what we are today. After all, there are plenty of intelligent people not having children, and there are plenty of less intelligent people having children.
This might also suggest why modern humans are prone to adopt primitive, outdated explanations of our universe that were constructed during our species infancy, even though there is significant scientific evidence to suggest contrary and more solid explanations.
I would think that human intelligence, is about as relative to a spiritual path as having good looks. It could be considered irrelevant. I think this view could bring one consolation, as it would suggest that mastery of Yoga is for everyone, and not just for an elite few. I makes Yoga a very universal path.
