Zombies page 2
Modern zombies, as portrayed in books, films, games, and haunted attractions, are quite different from both voodoo zombies and those of folklore. Modern zombies are typically depicted in popular culture as mindless, unfeeling monsters with a hunger for human brains and flesh, a prototype established in the seminal 1968 film Night of the Living Dead. Typically, these creatures can sustain damage far beyond that of a normal, living human (generally these can only be killed by a wound to the head, such as a headshot) and can pass whatever syndrome that causes their condition onto others.
Usually, zombies are not depicted as thralls to masters, as in the film White Zombie or the spirit-cult myths. Rather, modern zombies are depicted in mobs and waves, seeking either flesh to eat or people to kill or infect, and are typically rendered to exhibit signs of physical decomposition such as rotting flesh, discolored eyes, and open wounds, and moving with a slow, shambling gait. They are generally incapable of communication and show no signs of personality or rationality, though George Romero's zombies appear capable of learning and very basic levels of speech as seen in the films Day of the Dead and Land of the Dead.
Modern zombies are closely tied to the idea of a zombie apocalypse, the collapse of civilization caused by a vast plague of undead. The ideas are now so strongly linked that zombies are rarely depicted within any other context.
There are still significant differences among the depictions of zombies by various media; for one comparison see the contrasts between zombies by Night of the Living Dead authors George A. Romero and John A. Russo as they evolved in the two separate film series that followed. In some zombie apocalypse narratives, such as The Return of the Living Dead and Dead Set, zombies are depicted as being superhumanly quick and nimble, a further departure from the established genre stereotype.
A philosophical zombie is a concept used in the philosophy of mind, a field of research which examines the association between conscious thought and the physical world. A philosophical zombie is a hypothetical person who lacks full consciousness but has the biology or behavior of a normal human being; it is used as a null hypothesis in debates regarding the identity of the mind and the brain. The term was coined by philosopher David Chalmers.
Some zombie fans continue the George A. Romero tradition of using zombies as a social commentary. Organized zombie walks, which are primarily promoted through word of mouth, are regularly staged in some countries. Usually they are arranged as a sort of surrealist performance art but they are occasionally put on as part of a unique political protest.
Other organizations such as Zombie Squad use the genre as a way to promote disaster preparedness and to encourage horror fans to become involved in their community, through volunteering or hosting zombie themed charity fundraisers.
