4 Humans are thinking creatures. The tiger is stronger and even the average dog faster. Only by applying our intellectual capacities have we conquered the sky, the earth, and the water. We have neither wings nor claws. Yet we observe and understand everything from galaxies to gluons. We do this with our brains. For all our mastery, however, we are still far from understanding what sits in our skulls – the very thing that enables us to understand anything. Cognitive Science is not the study of the brain per se. Rather it is best described as the study of the nature of thinking, the problem of consciousness, the mystery of how mentality and all our many intelligences arise from the nervous system. It is truly an interdisciplinary field, drawing from neuroscience, philosophy, psychology, linguistics, computer science, biology, and anthropology. As long as they are working toward understanding the nature of intelligence, a person in any of these fields can be considered a “cognitive scientist”. It is not my goal, of course, to try to master all of them. The major I am creating falls under the Cognitive Science umbrella, but it has a specific focus. I am using Neuroscience, Philosophy, and Computer Science. The latter is the key. I believe that the mind can be understood as a complex machine-like system. I think the brain is like a computer – not the kind we know, the kind I’m using now – but as a system which operates according to certain logical principles best equated to those of a computer. Thus I would say essentially that my major is about understanding the “mind”. That means I am indeed learning about the brain and its biology, but it also means I am learning about principles of computation insofar as they can be applied toward understanding the mind. It is preferable to studying a combination of, say, Neuroscience and Computer Science because those majors each emphasize something different than what I am trying to get at. Neuroscience is primarily physiological, emphasizing cell structure and function and the biology of the brain. It also requires lab sciences which do not relate to the goal of this major, and are especially unnecessary given that I do not plan to go to med school. Computer Science as a major emphasizes programming for user applications, not the programming for research that I am interested in. Indeed Prof. DiLillo, my advisor from Computer Science, has pointed out that several of the required courses for the Computer Science major do not relate to Artificial Intelligence or Cognitive Modeling. The reason Cognitive Science pulls me as an academic and intellectual pursuit is because it satisfies a number of my natural curiosities and propensities. I am naturally multi-curious and it draws from multiple disciplines. I like seeing the big picture rather than the details, and it deals with high-level abstractions and systems. Neuroscience fascinates me but only in part; while I respect and enjoy the study of individual neurons, electro-chemical properties, and biological components of the nervous system, what I’m truly interested in is how these parts come together to form a whole. Finally, though I admit I still am unsure of my “life goals” and career plans, the extraordinary implications this field has for the real world: I believe that Artificial Intelligence will become a very real phenomenon in the decades to come. Surely there will always be controversy as to whether or not a computer can “think” as a human does. But as the gap in ability and complexity between human and machine erodes, so will the distinction between “Intelligence” and “Artificial” Intelligence. 5 As I said, I am unsure of my career goals. My goal is to earn a liberal arts education, learning critical thinking, writing, study habits, and a deeper understanding of something that interests me. As a matter of fact I believe this IIM will be exceptionally good for advancing these abilities. As an interdisciplinary study it requires one to examine a single problem from multiple perspectives. Furthermore, it takes discipline, rational thinking, and thoroughness to engage in scientific thinking. While I am not trying to do lab science or research, I am attempting to take the techniques of Computer Science and apply them toward a scientific problem. Furthermore, there is creativity in finding logical solutions to complex problems; there is ingenuity in inventing methods of testing perceived phenomena. Most importantly, there is a spirit of mutual respect, cooperation, and healthy competition in the scientific community, all of which I am learning and absorbing by engaging in this type of study. I do have plans to take on another major in addition to this IIM. All my life I have been passionate about Film, and so I would truly regret it if I did not take advantage of its recent expansion into a major. I was already declared a minor and had taken several courses when this happened, and I believe I can readily complete a major. This brings me to the courses I have chosen for this major, which I will now discuss by the departments they fall under: Philosophy courses relevant to Cognitive Science include Philosophy of Mind and Consciousness, Brain, & Self, both of which are taught by Jerry Samet, who is my advisor from Philosophy on my committee. I have taken both courses, and am now a TA in the former, and can assert with confidence that they have taught me to approach the idea of the mind with an open mind, forced to really think about what it means to think, and showed me different theories philosophers and cognitive scientists have of explaining consciousness and intelligence. Intro to Philosophy served as a background course in philosophy. In Neuroscience, I have taken Intro to Behavioral Neuroscience, with my primary IIM advisor Don Katz, Intro to Cognitive Neuroscience, and Human Neuropsychology. All of these are relevant as they teach what the brain’s functional components are and what they do. Different brain areas are responsible for different aspects of information processing: vision, language, motor function, etc. In order to understand what constitutes “intelligence” it is absolutely essential to become familiar with these processes. I do not know if I can take NPSY 140b, Principles of Neuroscience, because it requires biology, which requires chemistry, neither of which I am taking. Perhaps I might request permission from the instructor to take it, but I do not think it is essential to my major in any case. The course is about the very details of neural processing – neurochemical transmission, neuron biology, and so forth – but Cognitive Science is about the high-level processing that occurs as a result of neural networks, not about the function of individual cells. Indeed there are two more important Neuroscience offerings which address exactly that: Cognitive Modeling and Computational Neuroscience. These courses approach the mind from the perspective I talked about early: that the brain can be understood as a complex system like a computer 6 That leaves Computer Science. I have taken 11a, 21a, and 22a as background courses. The courses I am primarily interested in are Fundamentals of Artificial Intelligence, Computational Cognitive Science, and Computational Linguistics. These courses explore the ways programming can be used to simulate intelligence, cognitive processes, and language. Discrete Structures is also necessary; it is included in just about every cognitive science curriculum I’ve found from other schools, and is a prerequisite for classes like Artificial Intelligence at Brandeis. There is additionally the option of taking electives, so to speak, from Psychology and/or Linguistics. I have noted a couple of these courses in the Alternate Courses section. These courses are comparable to electives offered in Cognitive Science departments at other schools. Here I think I should also mention my plans to study abroad. By speaking with my IIM committee, as well as advisors from the study abroad office, I have determined that it will be possible to not only fulfill my course of study while abroad but even enhance it. I have narrowed it down to two universities: the “Artificial Intelligence and Cognitive Science” program at the University of Edinburgh, and Australia National University, where renowned philosopher of mind David Chalmers runs the Centre for Consciousness. I have listed example courses from both universities in my proposal. Courses at those schools include Artificial Intelligence and Cognitive Modeling, which I thus believe I could take as equivalents to the same Brandeis courses. There are other courses at those school not offered here but which would be highly valuable, such as a fascinating course at ANU called “System Architectural Understanding and the Human Brain”, which compares the hierarchical makeup of processing in the brain to that of a computer. I have included information about these programs in this packet. The Cognitive Science major at other schools is typically available in different tracks (akin to the IGS major here). At Berkeley, for example, Cognitive Science majors may concentrate in Cognitive Psychology, Computational Modeling, Linguistics, Philosophy, and Society Culture and Cognition. At Johns Hopkins, the Cognitive Science department has five areas: Cognitive Psychology and Neuropsychology, Linguistics, Computational Approaches to Cognition, Philosophy of Mind, and Neuroscience. These specializations are optional, but they do indicate that my choice to specifically focus on Computation is valid and comparable to what other schools offer. I have evaluated the Cognitive Science majors available at Berkeley, Johns Hopkins, UC-San Diego, Northwestern, and Brown (where my very own primary advisor Don Katz did the major), and included information about those programs here. My goal was to emulate as much as possible using Brandeis and study abroad courses. If there are any changes the IIM committee feels I should make I am more than open to doing so. I do plan to attend the committee meeting so that I can give a presentation and answer questions, and work with the committee to discuss any changes that may need to be made. I am truly excited about the prospect of doing Cognitive Science and it is with great enthusiasm that I hereby submit it for approval.
