ecause art is comparable to a folder rather than a file, its definition is subjective. It is determined by individual fiat. It will be whatever you wish to put into its folder.

For purposes of this page I give it my personal definition.

Art is anything that people add to their 'output' which is not functionally necessary and is other than the default properties of that output.

Example: The default leg of a chair (output) may be a long rectangular square. If its maker tapers the ends for no other reason than personal aesthetic preference, that tapering is art. If he tapers it for a functional (mechanical) reason it is part of 'engineering design' and not art. If he makes the leg round as on a lathe it may or may not be an artistic decision.
If for looks - artistic.
If to make it less likely to splinter or cause stubbed toe injuries, etc. it is engineering design.

There are two main aspects of art which cause the most debate.
