As we begin to consider the role that “non-physical components” might play in coming to terms with the nature of consciousness, a good place to begin is with our own very human emotions. In spite of having a clear and powerful biological foundation in brain physiology, our emotional responses are highly subjective in nature and what immediately stirs the feelings of one human being can produce nothing but indifference in another. Difficult to define, feelings can direct us in ways that are, in one instance, intuitive and insightful and in another, self-destructive and violent. Our response to stimulus of every sort can be examined, analyzed, and traced to specific locations within the brain, but our physiological response is only part of the story. Our emotions and feelings can also be influenced by forces far removed from simple biology.
Much has been written regarding the evolution of species on our planet, and we can infer a great deal from our increasing knowledge of the nature of life on our planet over the millions of years cognitive creatures have been evolving on it. Emotions served our primitive ancestors in their struggle to survive the dangers and challenges of life long ago, in the now familiar “fight or flight response” which still exists within us today, as well as in the development of nurturing inclinations. What began as an advantageous survival strategy has blossomed into a highly complex psycho-social phenomenon with far reaching implications in the study of the cognitive processes which are at the heart of consciousness. All of our evolutionary progress has built steadily upon the increasing capacity for cognitive development, and on the subsequent dependence on our emotional responses for survival. Over the millennia, we have taken the raw material provided by evolution, and slowly manipulated our mental and emotional environment to the point where we can now “rationalize” our emotional responses, and analyze them as a “component” of our burgeoning cognitive potential.
Beyond these considerations, and largely a result of our increased cognitive skills, our comprehension of the interrelatedness of all life on our planet, has also made us aware of the interactive nature of cognition. No longer are we simply the victims of a brutal world of “survival of the fittest,” but rather, the stewards of a global community of life forms which are remarkably dependent on each other not just for survival, but for fulfillment of a potential that expands well beyond the physiology of any one species. Humans are slowly coming to understand the importance of diversity not only within ecosystems and cultures, but also within their own individual consciousness.
The interrelatedness of all life in the phenomenal world reflects the even more complex and comprehensive relationships that support our profoundly dynamic inner life, represented in the relationships between cognition and physiology, between neurons and experience, between electrochemical phenomenology and synaptic function. Indeed, one could easily draw parallels that reach all the way from the most basic subatomic phenomena to the vastness of the known universe. The complexity of the brain is a perfect metaphor for the complexity of the universe!
The relationships between these various components of life in the physical universe, like all such associations, have some aspects in common which are visible and comprehensible, others that are a great deal more subtle, and yet others which are, for the present, utterly incomprehensible. In many cases, we can infer relationships between objects and phenomena based on observation or analysis of data relevant to the circumstances in which they occur, or by examining the bits and pieces left behind after centuries have passed. As cognitive creatures, with millions of years of evolution to support us, we can advance theories based on the observations and data accumulated over centuries of reflection and contemplation.
The story of humanity is in every way an accumulation of knowledge and experience, and the resulting expansion of human consciousness. Even if the acquisition of consciousness was initiated by our acquisition of an adequately equipped brain architecture, the accumulation of knowledge and experience made available to us as a result of that acquisition, is entirely our own doing.
Give someone a fish fillet, and they eat for a day. Teach them how to catch their own fish, and they eat for a lifetime. Give a hominid species a fully developed brain and nervous system, and eventually they will paint pictures on cave walls. Teach them through knowledge and experience to be creative and to innovate, and they will expand their consciousness beyond mere survival. Eventually, they will begin to unravel the mysteries of the universe.
As solid and predictable as the laws of physics seem to us today, not one of them eliminates the possibility of the existence of the spirit. And while the many diverse paths of spirituality offer an exciting array of avenues for us to pursue the spirit, not one of them can eliminate the laws of physics as they apply to the phenomenal world.
It doesn’t take an Einstein to conclude that both exist, and that both rely on the existence of the other. Our sense of being relies on being able to use our senses, but our senses do not bring us into being, nor do they attribute significance to our existence. They are our window to the world of experience and it is that world of experience that connects us to our sense of being and to the spirit.
