Consciousness, at its simplest, is awareness of internal and external existence. However, its nature has led to millennia of analyses, explanations, and debate by philosophers, scientists, and theologians. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of it. In the past, it was one's "inner life", the world of introspection, of private thought, imagination, and volition. Today, it often includes any kind of cognition, experience, feeling, or perception. It may be awareness, awareness of awareness, metacognition, or self-awareness, either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked.
The Chinese room argument holds that a computer executing a program cannot have a mind, understanding, or consciousness, regardless of how intelligently or human-like the program may make the computer behave. The argument was presented in a 1980 paper by the philosopher John Searle entitled "Minds, Brains, and Programs" and published in the journal Behavioral and Brain Sciences. Before Searle, similar arguments had been presented by figures including Gottfried Wilhelm Leibniz (1714), Anatoly Dneprov (1961), Lawrence Davis (1974) and Ned Block (1978). Searle's version has been widely discussed in the years since. The centerpiece of Searle's argument is a thought experiment known as the Chinese room.
Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate the mental state of the individual in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and experience having a sentient conscious mind.
Sentience is the ability to experience feelings and sensations. It may not necessarily imply higher cognitive functions such as awareness, reasoning, or complex thought processes. Sentience is an important concept in ethics, as the ability to experience happiness or suffering often forms a basis for determining which entities deserve moral consideration, particularly in utilitarianism.
William H. Calvin is an American theoretical neurophysiologist and professor at the University of Washington in Seattle. He is known for popularizing neuroscience and evolutionary biology, including the hybrid of those two fields, neural Darwinism. He relates abrupt climate change to human evolution and more recently has been working on global climate change issues.
Artificial consciousness, also known as machine consciousness, synthetic consciousness, or digital consciousness, is the consciousness hypothesized to be possible in artificial intelligence. It is also the corresponding field of study, which draws insights from philosophy of mind, philosophy of artificial intelligence, cognitive science and neuroscience.
John Cunningham Lilly was an American physician, neuroscientist, psychoanalyst, psychonaut, philosopher, writer and inventor. He was a member of a group of counterculture thinkers that included Timothy Leary, Ram Dass, and Werner Erhard, all frequent visitors to the Lilly home. He often stirred controversy, especially among mainstream scientists.
The eight-circuit model of consciousness is a holistic model originally presented as psychological philosophy by Timothy Leary in books including Neurologic (1973) and Exo-Psychology (1977), later expanded on by Robert Anton Wilson in his books Cosmic Trigger (1977) and Prometheus Rising (1983), and by Antero Alli in his books Angel Tech (1985) and The Eight-Circuit Brain (2009), that suggests "eight periods [circuits]" within the model. The eight circuits, or eight systems or "brains", as referred by other authors, operate within the human nervous system. Each corresponds to its own imprint and subjective experience of reality. Leary and Alli include three stages for each circuit, detailing developmental points for each level of consciousness.
Awareness, in philosophy and psychology, is a perception or knowledge of something. The concept is often synonymous to consciousness. However, one can be aware of something without being explicitly conscious of it, such as in the case of blindsight.
Artificial general intelligence (AGI) is a type of artificial intelligence (AI) that matches or surpasses human cognitive capabilities across a wide range of cognitive tasks. This contrasts with narrow AI, which is limited to specific tasks. AGI is considered one of the definitions of strong AI.
Reality tunnel is a theory that, with a subconscious set of mental filters formed from beliefs and experiences, every individual interprets the same world differently, hence "Truth is in the eye of the beholder". It is similar to the idea of representative realism, and was coined by Timothy Leary (1920–1996). It was further expanded on by Robert Anton Wilson (1932–2007), who wrote about the idea extensively in his 1983 book Prometheus Rising.
Psychonautics refers both to a methodology for describing and explaining the subjective effects of altered states of consciousness, including those induced by meditation or mind-altering substances, and to a research group in which the researcher voluntarily immerses themselves into an altered mental state in order to explore the accompanying experiences.
Cognitive liberty, or the "right to mental self-determination", is the freedom of an individual to control their own mental processes, cognition, and consciousness. It has been argued to be both an extension of, and the principle underlying, the right to freedom of thought. Though a relatively recently defined concept, many theorists see cognitive liberty as being of increasing importance as technological advances in neuroscience allow for an ever-expanding ability to directly influence consciousness. Cognitive liberty is not a recognized right in any international human rights treaties, but has gained a limited level of recognition in the United States, and is argued to be the principle underlying a number of recognized rights.
Bicameral mentality is a hypothesis introduced by Julian Jaynes who argued human ancestors as late as the ancient Greeks did not consider emotions and desires as stemming from their own minds but as the consequences of actions of gods external to themselves. The theory posits that the human mind once operated in a state in which cognitive functions were divided between one part of the brain that appears to be "speaking" and a second part that listens and obeys—a bicameral mind—and that the breakdown of this division gave rise to consciousness in humans. The term was coined by Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he makes the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.
The philosophy of artificial intelligence is a branch of the philosophy of mind and the philosophy of computer science that explores artificial intelligence and its implications for knowledge and understanding of intelligence, ethics, consciousness, epistemology, and free will. Furthermore, the technology is concerned with the creation of artificial animals or artificial people so the discipline is of considerable interest to philosophers. These factors contributed to the emergence of the philosophy of artificial intelligence.
In philosophy of mind, the computational theory of mind (CTM), also known as computationalism, is a family of views that hold that the human mind is an information processing system and that cognition and consciousness together are a form of computation. It is closely related to functionalism, a broader theory that defines mental states by what they do rather than what they're made of.
Animal consciousness, or animal awareness, is the quality or state of self-awareness within an animal, or of being aware of an external object or something within itself. In humans, consciousness has been defined as: sentience, awareness, subjectivity, qualia, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind. Despite the difficulty in definition, many philosophers believe there is a broadly shared underlying intuition about what consciousness is.
The Center of the Cyclone: An Autobiography of Inner Space is a 1972 book by John C. Lilly published by the Julian Press.
Philosophy of psychedelics is the philosophical investigation of the psychedelic experience. While psychedelic, entheogenic or hallucinogenic substances have been used by many traditional cultures throughout history mostly for religious purposes, recorded philosophical speculation and analysis of these substances, their phenomenological effects and the relevance of these altered states of consciousness to philosophical questions is a relatively late phenomenon in the history of philosophy. Traditional cultures who use psychedelic substances such as the Amazonian and Indigenous Mexican peoples hold that ingesting medicinal plants such as Ayahuasca and Peyote allows one to commune with the beings of the spirit world.
Models of consciousness are used to illustrate and aid in understanding and explaining distinctive aspects of consciousness. Sometimes the models are labeled theories of consciousness. Anil Seth defines such models as those that relate brain phenomena such as fast irregular electrical activity and widespread brain activation to properties of consciousness such as qualia. Seth allows for different types of models including mathematical, logical, verbal and conceptual models.
