The Evolutionary Advantage of Rationality

If man is built to be rational and spiritual, if his brain is hardwired for both, what does this tell us? It depends who you are and what you already believe.

From a purely practical point of view, attributes which survive within a species tend to have some kind of evolutionary advantage. The advantages of rationality are fairly obvious. The tools of rationality are developed in mankind to a much greater extent than in other species. These, together with complex language ability are the mental tools that allows us to create all physical tools. The use of tools, technology, has allowed man to become the dominant species on Earth.

We are still threatened as individuals by other species, but we have no threat as a species from other species. Threats do still exist, but many of them are now man made. They are threats due to success of our species.
