DEFINITIONS
The following definitions of various
beings should provide a framework
within which future ref's notes on this
subject will build.
Being: A self-aware, self-powered
individual with the capacity to sense
its environment and react to it. Humans,
intelligent aliens, robots, and androids
are all beings.
Robot: A mechanically-based artifact
manufactured to some set of specifications.
A robot may, or may not, be
anthropomorphic. Examples of robots
include the robot from Forbidden
Planet, and C3-PO from Star Wars.
Android: A biologically-based being
created to a set of specifications for
some purpose or duty. Androids exhibit
life, in that they are biologically living;
their distinction is that they were
created, rather than having evolved.
Androids generally are incapable of
reproduction, and can be identified by
close inspection. Some suggestions concerning
androids in science fiction
include permanent identifying marks
such as tattoos or a blue dyed skin. Ash,
from Alien, may be an android.
Clone: A biological copy of an existing being. A clone is a duplicate
produced through the use of technology;
alterations in the being's attributes
or qualities generally do not
occur. The relicts from Jack Vance's
novel, To Live Forever, are clones used
to produce a form of immortality for
certain individuals.
Prosthetics: Replacement parts of
biological beings. Prosthetics are intended
to duplicate ordinary capacity
for individuals who have lost organs or
limbs through accident or disease.
Bionics: Enhanced replacement parts
for biological beings. Unlike prosthetics,
bionics provide a function better than
the original organ or limb.
Cyborg: A biological individual who
has been replaced in great part by
mechanical components, usually (although
not always) for purposes which
natural attributes will not function.
A cyborg may be equipped with a very
tough artificial skin, special vision
lenses, and provision for special energy
sources, thus making possible activity in
vacuum or under great pressure.
