When a human looks in the mirror, the natural response is usually, “I see myself” (my self?). The concept of “the self" is one only a select few species have been blessed with. Humans, apes, in recent years scientists have even discovered that dolphins and whales are capable of having a sense of “self.” Self-awareness is this rare ability that enables these creatures, humans most of all, to distinguish who they are as unique organisms, while at the same time cohabiting and cooperating with those around them. But what allows us to do this? What gives us this capacity for self-awareness and compassion for others? When we recognize ourselves in a mirror are we experiencing a phenomenon based in divinity, do we possess self-awareness because God deemed it so? Or can the phenomenon be explained empirically, has it come to be through thousands of years of evolution?
Now, I’m not discrediting spiritual beliefs. There are spiritual aspects to self-awareness and the concept of “self” that are solely offered in religion. For example the concept of “the self” has played an enormous role in the Hindu religion for centuries. Nevertheless, like most real-world occurrences, I firmly believe “self-awareness” is of an empirical nature and because it is an event that occurs cognitively, we are capable of investigating it under the microscope of classical logic systems and dynamic coupling systems conversely; the latter being the system I will focus on in this paper. Knowing this, the next question I want to pose is, how can we take this information and apply it toward developing an artificially intelligent machine that experiences self-awareness?
Unfortunately, knowing what kind of system best suits a phenomenon such as self-awareness isn’t enough; as expected, to get to the core of “the self” one is required to dig much deeper. One needs to ask, what sets human self-awareness apart from the rest? I speculate, along with many other scientists and philosophers that our self-awareness stems from the sociological construction of language, this ability to communicate that we have developed and fine-tuned century after century. However not all authorities believe this idea has uniform implications. Some claim the answer can be found through the study of solitary introspection, others claim dynamic interactions between subjects yield a greater understanding of the role language plays in our developmental processes. There are various views and the differences lie in the manner in which each individual believes language achieves its goal. Obviously all experts lean toward their respective claims and while each claim has something of value to bring to the table, only through the extensive study of dynamic interactions between individuals, the ability to converse, will we as a species finally begin to fully grasp the mystery of “the self.” This isn’t to say that self-reflection and introspection doesn’t have its place, but it is through social interactions and the development of language that we are even capable of such introspection in the first place, they too are a fundamental part of self-awareness, Without the words, what would your thoughts sound like? Thankfully this is a view shared by many people, other than myself.
For instance Lev Vygotsky, 20th century Russian psychologist, asserted that linguistics not only function as a medium for transferring knowledge and information from one party to another but could be used as a tool for structuring and controlling real-time interactions with our environment. (Clark 195) This is a view that falls in line with the coupling concept previously mentioned, Dynamic Systems Theory, or DST. According to Vygotsky, language is responsible for helping us complete real world tasks, common and otherwise through interacting and conversing with other parties along with the environment around us. An example of this phenomenon elucidated by Vygotsky is the act of a child learning how to tie his or her shoelaces.
Let’s think about the way this task is accomplished. In most cases when a child is learning how to tie their own shoelaces there are several components at work. Firstly, they have a vigilant parent or authority figure. Secondly, this individual is either explaining the actions in chronological order or utilizing some kind of rhyme (both of which are contingent upon language) to help the child remember each step involved; for some reason the image of a rabbit always comes to mind. This process, this union of parent, child, and linguistic interaction has been proven to improve the level of mastery and accelerate the speed at which the child is capable of learning to tie their shoes because upon retaining the initial information they no longer have to rely on a parent to act; instead, they can rely on their own capacities for pattern recognition and symbolic representation to complete the task. A child can conduct a personal dialogue thanks to linguistics. By drawing on the meaning of the aforementioned words and recounting said words in the same pattern in which they were delivered, the child is able to guide their behavior, focus their attention on the action at hand, and guard themselves against common errors that might take place, thus becoming more aware of themselves and the cognitive space around them. (Clark 195) This method of dynamic pattern recognition wouldn’t be possible if not for A) The pairing of the initial two agents (Parent and child), B) the use of linguistics (the words being used to help the child recall the steps), and C) the external interaction between the individual and their environment (the child and their shoelaces). Knowing this, one could surmise along with Vygotsky that developmental process is greatly enhanced through dynamic interactions with others. This is an important note considering the next topics of discussion, the linguistic encoding of ideas and thoughts, i.e. writing, and path dependence.
Firstly, the linguistic encoding of ideas and thought processes is a phenomenon that I believe is taken for granted in the 21st century. In an age of “LOLs,” “OMGs,” and “BRBs” people’s perception of writing’s role in our lives has become greatly diminished from what it truly is, a developmental miracle. In section 10.3 of Andy Clark’s book Being There, Clark discusses how the written word has given humanity the ability as a species to solidify and preserve our thoughts and ideas outside of our distinctive units. Doing so has allowed us to share said thoughts and ideas with countless individuals who are then capable of critiquing, modifying, learning from, and finally teaching these concepts to a larger number of people. (Clark 204) It’s a never-ending process of learning achieved through interaction and discussion; all of which heavily relies on linguistics. For anyone who has ever been a conversation enthusiast, this is an exciting prospect; we learn the most about ourselves by conversing with others! But Clark doesn’t stop there. He goes on to enforce the necessity of this intellectual coupling of individuals when he claims that by studying a certain aspect of the connectionist model of the human brain, known as “path dependence,” one can gain an even greater appreciation for how linguistics has pushed us to our current point of self-awareness as a society.
“Path dependence” is the notion that the way in which our brain learns new skills and concepts is contingent upon experiences and concepts retained prior to learning the new ones. Essentially this means you can’t learn certain new ideas or expand upon old ones without learning the necessary prerequisites for said ideas beforehand, not all of which are readily available to everyone. Clark puts it this way, “you can’t get everywhere from anywhere, and where you are now strongly constrains your potential future intellectual trajectories.” Thus we are constantly on the edge of our own capacities, forced into the implication, “a solitary unit or individual is incapable of reaching their maximum potential.” Yes, one can write their ideas down, one can pondered the nature of the universe and vocalize one’s findings aloud until they are blue in the face, however all individual agents have a limit and there is no escaping the fact that it is impossible for any one person to know everything; we must confide in others and take part in a community. However this is not a negative realization, if anything it’s an overwhelmingly positive one. I believe this unifying thought allows us to say with confidence that it is necessary to have some kind of intellectual coupling or linguistic community for the level of self-awareness and intellectual progression we have made as a society thus far. Humankind is a socially oriented species to begin with thus it only makes sense we rely on others to work past our brain’s “path dependency” and reach our full potential. Let me elaborate on this by using an expanded version of Clark’s example of Joey and Mary.
Picture a scenario in which all of Joey’s prior experiences and ideas could be made readily available. However Joey is a limited agent, he can’t expand upon these ideas alone and one in particular has him completely stumped. Thus for Joey’s idea to reach its full potential he must coexist in an intellectual space that can only be provided by another individual with their own experiences and ideas, in this case Mary. Now imagine that these two individuals accidentally bump into one another while walking out of the grocery store one day. This causes Mary to drop the bag of groceries she was carrying and Joey to stop and help pick them up. One thing leads to another and they end up conversing over a cup of coffee. This provides the perfect opportunity for both agents to learn something and grow. All of Joey’s and Mary’s experiences and ideas are fully accessible to both parties and only now can the idea puzzling Joey realize its full potential through the agents conversing. “The path to a good idea can now criss-cross individual learning histories so that one agent’s local minimum becomes another’s potent building block.” (Clark 206) This shows that if given an intelligent and self-aware community with a linguistic means of conversing, and presuming an individual is an active member of said community, one’s ability to develop their mind, their “self,” grows exponentially.
It’s time to shift gears. Knowing all of this, I want to pose the same question I asked earlier in the paper, how do we take this information and apply it toward developing an artificially intelligent machine that experiences self-awareness? To answer this question I’ve devised a set of requirements.
Above all else, we’ve learned the most crucial component when becoming self-aware is a sense of linguistics. When dealing with different species or entities other than our own, there is something extra that needs to be taken under consideration and that is, the means of communication doesn’t have to be universal; instead its only requirement is that it be entity specific. For self-awareness to occur, all members of any given community must speak the same language or a derivative language. A prime example of this would be the way in which dolphins converse with one another. Dolphins have evolved, like humans, to experience self-aware tendencies; yet the languages spoken by both parties are drastically different. Dolphins converse by utilizing high-pitched tones and frequencies, while humans interact with each other through phonics or visual representations of said phonics, i.e. sign language. Regardless of the differences, both species have developed a sense of “self.” When considering self-awareness in artificially intelligent machines, one must utilize the same principles; a machine-based language will most likely be one of a binary nature comprised of ones and zeros. However this still qualifies as a language, thus fulfilling my first requirement for self-awareness.
The second principle that must be taken into consideration when pondering the nature of self-awareness is personal experience. Language alone isn’t enough to guarantee a species or entity will evolve to the point of being self-aware. They must be capable of learning and undergoing growth. This is what essentially gives one the ability to relate. For this to occur in artificially intelligent machines, the machines themselves must be capable of learning and retaining knowledge in some way. The best way to achieve this would be through the use of a dynamic system capable of continually building upon itself. This would give an artificially intelligent machine the adaptability necessary for a task such as learning; thus fulfilling my second requirement for self-awareness, experience.
The final requirement for achieving self-awareness is interaction. The capacity to pull from a common knowledge base and articulate one’s own personal experiences and ideas through whatever form of language is being used in the community is crucial to becoming aware of one’s self and those around them. In other words, an agent must possess a means of interacting to achieve self-awareness. This brings us back to the idea of “path dependency.” Alone, no agent will ever be complete; they will remain imperfect and stagnant. That old expression is true, “it takes two to tango,” and the coupling with a second agent of one’s own species, or in the case of machines, a second unit, is the only way to reach one’s maximum potential. For a machine this requirement can be easily met; however there are two separate routes. First, if a unit lacks embodiment, being part of a network could potentially give said unit the necessary interactions to learn and grow. Second, if embodiment has been achieved, then the interactions between machines might be similar to that of humans; two separate units occupying the same environment while conversing in real-time.
In conclusion, achieving self-awareness is a process. It requires multiple components, many steps, and time to be fully realized. It relies upon language and the ability to socialize. There is no set algorithm for self-awareness; however given the right environmental stimuli, tools, and interactions, any species, synthetic or otherwise, possesses the capability of reaching such a point. In the case of artificially intelligent machines, a future in which they develop self-awareness (though purely hypothetical at the moment) is an extremely real and stimulating possibility. Machines won’t accomplish this alone; we are the designers, the creators, therefore our hands will play an integral part in their development. We live in an exciting time and if that future ever comes to fruition there will be one question more important than all others, “are you a cylon?”
Most Hindus believe that the soul, the true "self" of every person, is eternal; this soul is referred to as Atman. According to the monistic/pantheistic theologies of Hinduism this Atman is ultimately indistinguishable from Brahman, the supreme spirit. Hence, these schools are called non-dualist. The goal of life is to realize that one's Atman is identical to Brahman, the supreme soul. This unifying idea essentially means that everyone is part of the same being. (“Concept of God”)
This theory deals with the long-term qualitative behavior of dynamic systems, and the studies of the solutions to the equations of motion of systems that are primarily mechanical in nature; although this includes both planetary orbits as well as the behavior of electronic circuits and the solutions to partial differential equations that arise in biology. Much of modern research is focused on the study of chaotic systems. (“Overview”)
I’ve made sure to include this due to the vast number of languages spoken by humans alone.
