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, theologians, and all of science. 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 mind. 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, 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.
Daniel Clement Dennett III is an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.
Julian Jaynes was an American researcher in psychology at Yale and Princeton for nearly 25 years, best known for his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind. His career was dedicated to the problem of consciousness: "the difference between what others see of us and our sense of our inner selves and the deep feelings that sustain it. ... Men have been conscious of the problem of consciousness almost since consciousness began." Jaynes's solution touches on many disciplines, including neuroscience, linguistics, psychology, archeology, history, religion and analysis of ancient texts.
Maurice Jean Jacques Merleau-Ponty was a French phenomenological philosopher, strongly influenced by Edmund Husserl and Martin Heidegger. The constitution of meaning in human experience was his main interest and he wrote on perception, art, politics, religion, biology, psychology, psychoanalysis, language, nature, and history. He was the lead editor of Les Temps modernes, the leftist magazine he established with Jean-Paul Sartre and Simone de Beauvoir in 1945.
The mind is that which thinks, imagines, remembers, wills, and senses, or is the set of faculties responsible for such phenomena. The mind is also associated with experiencing perception, pleasure and pain, belief, desire, intention, and emotion. The mind can include conscious and non-conscious states as well as sensory and non-sensory experiences.
The philosophy of perception is concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world. Any explicit account of perception requires a commitment to one of a variety of ontological or metaphysical views. Philosophers distinguish internalist accounts, which assume that perceptions of objects, and knowledge or beliefs about them, are aspects of an individual's mind, and externalist accounts, which state that they constitute real aspects of the world external to the individual. The position of naïve realism—the 'everyday' impression of physical objects constituting what is perceived—is to some extent contradicted by the occurrence of perceptual illusions and hallucinations and the relativity of perceptual experience as well as certain insights in science. Realist conceptions include phenomenalism and direct and indirect realism. Anti-realist conceptions include idealism and skepticism. Recent philosophical work have expanded on the philosophical features of perception by going beyond the single paradigm of vision.
Blindsight is the ability of people who are cortically blind to respond to visual stimuli that they do not consciously see due to lesions in the primary visual cortex, also known as the striate cortex or Brodmann Area 17. The term was coined by Lawrence Weiskrantz and his colleagues in a paper published in a 1974 issue of Brain. A previous paper studying the discriminatory capacity of a cortically blind patient was published in Nature in 1973. The assumed existence of blindsight is controversial, with some arguing that it is merely degraded conscious vision.
Thomas Hill Green, known as T. H. Green, was an English philosopher, political radical and temperance reformer, and a member of the British idealism movement. Like all the British idealists, Green was influenced by the metaphysical historicism of G. W. F. Hegel. He was one of the thinkers behind the philosophy of social liberalism.
In philosophy of perception and epistemology, naïve realism is the idea that the senses provide us with direct awareness of objects as they really are. When referred to as direct realism, naïve realism is often contrasted with indirect realism.

The Family That Walks on All Fours is a BBC Two documentary that explored the science and the story of five individuals in the Ulas family, a Turkish family in Southeastern Turkey that walk with a previously unreported quadruped gait.
Enactivism is a position in cognitive science that argues that cognition arises through a dynamic interaction between an acting organism and its environment. It claims that the environment of an organism is brought about, or enacted, by the active exercise of that organism's sensorimotor processes. "The key point, then, is that the species brings forth and specifies its own domain of problems ...this domain does not exist "out there" in an environment that acts as a landing pad for organisms that somehow drop or parachute into the world. Instead, living beings and their environments stand in relation to each other through mutual specification or codetermination" (p. 198). "Organisms do not passively receive information from their environments, which they then translate into internal representations. Natural cognitive systems...participate in the generation of meaning ...engaging in transformational and not merely informational interactions: they enact a world." These authors suggest that the increasing emphasis upon enactive terminology presages a new era in thinking about cognitive science. How the actions involved in enactivism relate to age-old questions about free will remains a topic of active debate.
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.
Peter Carruthers is a British-American philosopher and cognitive scientist working primarily in the area of philosophy of mind, though he has also made contributions to philosophy of language and ethics. He is a professor of philosophy at the University of Maryland, College Park, an associate member of Neuroscience and Cognitive Science Program, and a member of the Committee for Philosophy and the Sciences.
The Oxford Book of Modern Science Writing is an anthology of scientific writings, arranged and introduced by Richard Dawkins of the University of Oxford. Published first in March 2008, it contains 83 writings on many topics from a diverse variety of authors, which range in length from one to eight pages. All inclusions are dated post-1900, and include poetry, anecdotes, and general philosophical musings.
The neural correlates of consciousness (NCC) refer to the relationships between mental states and neural states and constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept. Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate with a specific experience. The set should be minimal because, under the materialist assumption that the brain is sufficient to give rise to any given conscious experience, the question is which of its components are necessary to produce it.
Wolfgang Prinz is a German cognitive psychologist. He is the director of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and an internationally recognized expert in experimental psychology, cognitive psychology and philosophy of mind. He is the founder of the common coding theory between perception and action that has a significant impact in cognitive neuroscience and social cognition.
Professor Robert William Kentridge is a British experimental psychologist.
