Think Zombie

These symptoms suggest their frontal lobes probably aren't functioning correctly, Voytek said. In animal studies, cutting connections to the frontal lobes causes lots of problems, he added. Then there's the matter of zombie communication, or lack thereof. Voytek and Verstynen made a educational video in which they "diagnosed" zombies with a condition called Wernicke's aphasia, which results from damage to a bundle of connections between the brain's temporal and parietal lobes.

Of course, brain damage is not a joking matter, Voytek said, but he finds it interesting to think about. Zombies may have impaired brain function in many ways, but they do have a razor-sharp sense of smell — at least when it comes to sniffing out living human flesh. In a scene from the movie and comic book "Walking Dead," the protagonists smear themselves with the organs of dead zombies to prevent "live" zombies from smelling them.

By comparison, healthy humans are thought to have a poor sense of smell. But studies have shown that people can track scents really well if they focus on the task, Voytek said.

In one study, blindfolded undergraduates at the University of California, Berkeley, were able to track a streak of chocolate in the grass by smell alone, and did it surprisingly well. So the zombie's ability to tell healthy bodies from decaying ones i. All of these theories about zombie neuroscience are idle speculation. But could zombies exist in real life? Or do zombies experience consciousness?

In Schlozman's view, zombies are much like a crocodile. They may not be conscious in the same way humans are, but they are aware of their surroundings and respond to their environment.

From the philosophical standpoint of consciousness, if zombies can recognize "qualia" -- instances of consciousness, sensing things like pain, color, smell or temperature -- then they must be conscious. This year the center is running a series of interdisciplinary workshops on zombies and consciousness. Even if we thought zombies were just sick people, an infection that reanimates corpses isn't a normal disease, so we'd probably want to double check. Just to be sure. Using the same methods we employ to probe whether or not animals are conscious, we could test whether or not zombies think on a higher level.

If a zombie could recognize himself in the mirror, we'd have to assume that zombie had self awareness. If we could see that they didn't have a thalamus, for example, scientists would agree that zombies probably wouldn't be conscious. If there were a lot of complex interactions between regions of their zombie brain, that would imply a high level of consciousness. But it might be tough to wrestle a zombie into an MRI. One way we test for consciousness in animals is by having them take a good look in the mirror.

Most primates, dolphins, elephants and even magpies can recognize their own reflection. We could also test whether zombies were capable of what's called meta-cognition -- if they were aware of their own thoughts. When testing for advanced forms of consciousness, scientists give animals perceptual tasks, like picking which dot is slightly bigger in a set or choosing which picture they've already been shown.

Then the zombie would be asked to gamble on their answer. Furthermore, when concept of self is deemed to correspond to physical reality alone reductive physicalism , philosophical zombies are denied by definition. When a distinction is made in one's mind between a hypothetical zombie and oneself assumed not to be a zombie , the hypothetical zombie, being a subset of the concept of oneself, must entail a deficit in observables cognitive systems , a "seductive error" [4] contradicting the original definition of a zombie.

Verificationism [1] states that, for words to have meaning, their use must be open to public verification. Since it is assumed that we can talk about our qualia, the existence of zombies is impossible. A related argument is that of "zombie-utterance".

FYI: Do Zombies Experience Consciousness? | Popular Science

If someone were to say they love the smell of some food, a zombie producing the same reaction would be perceived as a person having complex thoughts and ideas in their head indicated by the ability to vocalize it. If zombies were without awareness of their perceptions the idea of uttering words could not occur to them. Therefore, if a zombie has the ability to speak, it is not a zombie.

Artificial intelligence researcher Marvin Minsky saw the argument as circular. The proposition of the possibility of something physically identical to a human but without subjective experience assumes that the physical characteristics of humans are not what produces those experiences, which is exactly what the argument was claiming to prove. To show this, he proposes "zoombies", which are creatures non physically identical to people in every way and lack phenomenal consciousness. If zoombies existed, they would refute dualism because they would show that consciousness is not nonphysical, i.

Paralleling the argument from Chalmers: It's conceivable that zoombies exist, so it's possible they exist, so dualism is false. Stephen Yablo 's response is to provide an error theory to account for the intuition that zombies are possible. Notions of what counts as physical and as physically possible change over time so conceptual analysis is not reliable here.

Yablo says he is "braced for the information that is going to make zombies inconceivable, even though I have no real idea what form the information is going to take. The zombie argument is difficult to assess because it brings to light fundamental disagreements about the method and scope of philosophy itself and the nature and abilities of conceptual analysis. Proponents of the zombie argument may think that conceptual analysis is a central part of if not the only part of philosophy and that it certainly can do a great deal of philosophical work.

However others, such as Dennett, Paul Churchland and W. Quine , have fundamentally different views. For this reason, discussion of the zombie argument remains vigorous in philosophy. Some accept modal reasoning in general but deny it in the zombie case. Hill and Brian P. Mclaughlin suggest that the zombie thought experiment combines imagination of a "sympathetic" nature putting oneself in a phenomenal state and a "perceptual" nature imagining becoming aware of something in the outside world.

Each type of imagination may work on its own, but they're not guaranteed to work when both used at the same time. Hence Chalmers's argument needn't go through. As an analogy, the generalized continuum hypothesis has no known counterexamples, but this doesn't mean we must accept it. And indeed, the fact that Chalmers concludes we have epiphenomenal mental states that don't cause our physical behavior seems one reason to reject his principle.

Another way to construe the zombie hypothesis is epistemically — as a problem of causal explanation, rather than as a problem of logical or metaphysical possibility. The " explanatory gap " — also called the " hard problem of consciousness " — is the claim that to date no one has provided a convincing causal explanation of how and why we are conscious.

It is a manifestation of the very same gap that to date no one has provided a convincing causal explanation of how and why we are not zombies. Frank Jackson 's Mary's room argument is based around a hypothetical scientist, Mary, who is forced to view the world through a black-and-white television screen in a black and white room. Mary is a brilliant scientist who knows everything about the neurobiology of vision.

Even though Mary knows everything about color and its perception e. If Mary were released from this room and were to experience color for the first time, would she learn anything new? Jackson initially believed this supported epiphenomenalism mental phenomena are the effects, but not the causes, of physical phenomena but later changed his views to physicalism , suggesting that Mary is simply discovering a new way for her brain to represent qualities that exist in the world.

Swampman is an imaginary character introduced by Donald Davidson. If Davidson goes hiking in a swamp and is struck and killed by a lightning bolt while nearby another lightning bolt spontaneously rearranges a bunch of molecules so that, entirely by coincidence, they take on exactly the same form that Davidson's body had at the moment of his untimely death then this being, 'Swampman', has a brain structurally identical to that which Davidson had and will thus presumably behave exactly like Davidson.

He will return to Davidson's office and write the same essays he would have written, recognize all of his friends and family and so forth.
