Consciousness begins as a spark, but grows into a flame which develops as we mature into adulthood. I don't believe that higher levels of consciousness are in any way a recent development. Certainly there is evidence of highly evolved communities living on Earth literally thousands of years ago, and I imagine that they would have been able to rise above the cycles of agriculture and horticulture when conceiving and planning their intricate cities and civilisations.
The pyramids, and the Mayan calendar are good examples of just how developed some ancient civilisations truly were. As far as spiritual consciousness goes, I do believe that we are entering an era where the physical realm in terms of possessions will become secondary to that of an appreciation of Mother Earth, and our connection to each other and the planet as a whole.
Dragonwolf137. Our conscious awareness, as you call it, is not a recent evolvement. Think Ancient Greek philosophers, the Ancient Sages of India, and various masters such as Jesus the Christ, Guatama the Buddha, etc.. I can see what you're getting at, though, most people didn't have the time to examine what and who we are because they were too busy.
Today, people 'make themselves busy' by escaping into T.V. Computer games, films etc.. However, if you just examine the amount of spiritually-awakening stuff on these Hubsite alone, you'll possibly begin to accept - as I do - that we are, as a species, becoming more and more conscious, more and more aware.
Sounds like you need to read some Rene Descartes...
Consciousness is the next highest form of energy which leads to the ultimate or perfection Life /Light...What we see and experience in this age are merely different and lesser forms of energy in varying degrees. While consciousness can say I AM ....... in a limited perspective , the perfection of it will Say I AM with an unlimited perspective.
This isn't the answer; I just wanted to say I think its funny we use the means of the question to answer it in a clever ironic twist by delving deep in our conciousness to shed light on the subject :D And also i'm delving deep in my consciousness to make a response that won't answer said question but confuse readers when the question is sadly never answered.
One theory is Julian Jayne's "The Origin of Consciousness in the Breakdown of the Bicameral Mind". But it is obviously not complete, given the prevalence of religious fervor and schizophrenia.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
