All of us are now self aware so there is no logical excuse not to be factual and truthful as well. Those who are not factual and truthful are playing at something that is not correct and can only have an ulterior motive for their deceptions. This intelligence versus animal theme is akin to maturity against immaturity. We are not now living under extreme survival conditions like our ancient under evolved forebears. We are all living in or around modern civilizations for the most part and as such are recipients of its benefits whether we realize it or not. Everytime we drink from a bottle instead of from a stream we are part of modernity. Everytime we eat a meal from a wrapper and not directly from some fire pit we are part of enlightenment. The clothes we wear if not made from some animal hide is another fact of our enlightenment. We cannot claim to be an animal if we are still living in an apartment or house or driving a vehicle.
All of us are intelligent it is just by degree that we are not all the same. Some of us embrace intellectualism with all we have and others fight against it despite illogical hypocrisies. I am a human being who at some point in the evolution of our species was related to the animal more than the intellectual. Those millenniums are behind us now and the animal aspect of who I was related has all but disappeared and the human being I am now is all intellect. Everything in my life, my behavior and what I think about is run through the filter of my logic and my personal principles of honor and nobleness. So those politicians who still propagate an animal survival of the fittest society are not using facts or truths.
