Perception is an adaptive interface to reality like Windows is to that of a PC. Natural selection has shaped our perceptions in ways that help us survive. Our perception of reality is not based on complete objective truth but rather on our ability to adapt to our environment.
Abstract mental representation is a crucial component of our species success and technological advancement. It is impossible to launch a rocket, place a satellite in orbit, or construct a functioning cell phone based on perception alone. Moreover, perception and theory are far more intertwined than scientists admit. No perception is truly direct. Like everything else that takes place by way of the brain, perception is a product of neural representation and is subject to influence by theory-based phenomena.
But the information, the brain operates on and used to evolve into, was already preexistent within nature. Thoughts are the mind's biological representations and reflection of the universe's structure and, in a sense, did preexist as physical complexities encoded in reality's physical nature.
The universe evolves into a more and more complex form because the potential for it too is inherent within its substance and ability. Humans (life forms) may be the most complex and developed form of organized matter in the known universe, not just because of our brain's complexity, but its ability to process information as conscious self-awareness. Consciousness may not be a mere individual characteristic but could be global in nature as a result of our species interaction with nature and each other. Communication, in the way of thought and language, is an important key to our survival and over time has transformed into a herd mentality or collective intellect or swarm intelligence, ie; science and google. The complete objective truth of reality might be emerging as the evolution of humanity's mental ability to conceptualize the universe as a whole entity, not separated by distinctions.
