Broadly viewed, scientific approaches are based on two core concepts. The writings of Avicenna, Ibn Tufail, and Aquinas on the tabula rasa theory stood unprogressed and untested for several centuries. It has been argued that consciousness emerged i exclusively with the first humans, ii exclusively with the first mammals, iii independently in mammals and birds, or iv with the first reptiles.

Bonaventure also thirteenth century was one of the fiercest intellectual opponents of Aquinas, offering some of the strongest arguments toward the Platonic idea of the mind.

History[ edit ] Tabula rasa is a Latin phrase often translated as "blank slate" in English and originates from the Roman tabula used for notes, which was blanked by heating the wax and then smoothing it.

His arguments, however, were very abstract. The assumption of an avian consciousness also brings the reptilian brain into focus. David Chalmers has argued that A-consciousness can in principle be understood in mechanistic terms, but that understanding P-consciousness is much more challenging: So, when we perceiveinformation about what we perceive is access conscious; when we introspectinformation about our thoughts is access conscious; when we rememberinformation about the past is access conscious, and so on.

The reason is the structural continuity between avian and reptilian brains, meaning that the phylogenetic origin of consciousness may be earlier than suggested by many leading neuroscientists. So how similar are they? Although dream sleep and non-dream sleep appear very similar to an outside observer, each is associated with a distinct pattern of brain activity, metabolic activity, and eye movement; each is also associated with a distinct pattern of experience and cognition.

The same cortical machinery is also used to attribute awareness to oneself. Several theorists have therefore proposed quantum mind QM theories of consciousness. In either case, the ultimate goals are to develop techniques for assessing consciousness objectively in humans as well as other animals, and to understand the neural and psychological mechanisms that underlie it.

This approach was first proposed by the philosopher Edmund Husserland later elaborated by other philosophers and scientists. In contrast to the raw electrical responses that do not correlate with consciousness, the modulation of these responses by other stimuli correlates surprisingly well with an important aspect of consciousness: A related word was conscientiawhich primarily means moral conscience.

For example, Daniel Dennett and Douglas Hofstadter argue that anything capable of passing the Turing test is necessarily conscious, [65] while David Chalmers argues that a philosophical zombie could pass the test, yet fail to be conscious. Lovelace was essentially dismissive of the idea that a machine such as the Analytical Engine could think in a humanlike way.

These experiences, considered independently of any impact on behavior, are called qualia. Nor is it explained what specific causal role conscious integration plays, nor why the same functionality cannot be achieved without consciousness.

Some argue that consciousness is a byproduct of evolution. For one thing, it seems to violate the principle of parsimonyby postulating an invisible entity that is not necessary to explain what we observe.

Consciousness

Perception, again, is an impression produced on the mind, its name being appropriately borrowed from impressions on wax made by a seal; and perception they divide into, comprehensible and incomprehensible: A positive result proves that machine is conscious but a negative result proves nothing.

There are also a variety of circumstances that can change the relationship between the mind and the world in less drastic ways, producing what are known as altered states of consciousness. This measure was shown to be higher in individuals that are awake, in REM sleep or in a locked-in state than in those who are in deep sleep or in a vegetative state, [98] making it potentially useful as a quantitative assessment of consciousness states.

Both may be renewed repeatedly, by melting the wax of the tablet or by erasing the chalk on the slate. Edelman also differentiates between what he calls primary consciousness which is a trait shared by humans and non-human animals and higher-order consciousness as it appears in humans alone along with human language capacity.

The Turing test is commonly cited in discussions of artificial intelligence as a proposed criterion for machine consciousness; it has provoked a great deal of philosophical debate.The origin of the modern concept of consciousness is often attributed to John Locke's Essay Concerning Human Understanding, published in Locke defined consciousness as "the perception of what passes in a man's own mind".

His essay influenced the 18th-century view of consciousness, and his definition appeared in. History.

Tabula rasa is a Latin phrase often translated as "blank slate" in English and originates from the Roman tabula used for notes, which was blanked by heating the wax and then smoothing it.

This roughly equates to the English term "blank slate" (or, more literally, "erased slate") which refers to the emptiness of a slate prior to it being written .
