It is therefore to be expected that the future evolution of intelligent species such as our own will mostly depend on the ability we have to be clear about the world. This will give power to those species. But this is not enough to secure their survival. We know, by looking both at our history and to the rest of nature, that a balance has always risen that prevented one species to achieve the monopoly of resources. Will intelligent species be an exception? Well, first of all the more intelligent we are the more we will understand that we are part of an ecosystem, that we depend on living trees and clean oceans and a wide diversity of life. Intelligent beings will likely want to live in a world full of diversity, so, in that sense, they will really be as if keepers of the world, functioning like nature, preserving natural diversity. Man, on the other hand, has been more guided by greed, immediate gratification, than intelligence. Instead of trying to preserve the biodiversity like a loving father or a keeper, many men have been thinking about dollars, fame, or business in general. Animals and landscapes are many times treated as objects to be traded and profited from. This leads to blind action whose outcome can be quite surprising. If we devastate the world we will face hunger and poverty in the future and we will live in an ugly world filled with our own constructions and polluted with our dejects. On the other hand when a species is very prevalent in a ecosystem it is natural that predators slowly appear. These predators can operate at the normal physical level, like diseases, but they can also operate at the new intellectual level. Just like ideas spread (sometimes we speak of memes) at the intellectual level so too can intellectual viruses spread. Intellectual virus are lies that have high power of diffusion but also have the ability to displace truth. A society dominated by intellectual viruses is doomed to failure for its mistaken views of the world will condemn her, sooner or later, to
