Objective

The objective of this collection is simply to relate the emotions, ideas, and thoughts of a caged animal. Those cages are varied, but confinement is the key to understanding the following text. Also, among the objectives is the desire to explain without explicating, to reveal while concealing. This may all seem rather contradictory but as the reader progresses through the project they ought to be able to see each of these opposites come together, like unrelated footsteps in sand.

Difficulties

The only tools available for the objectives of this collection were words. Unfortunately, they are abstract inexactitudes for abstract exactness. The best attempts were made to recreate the author’s original work. No censorship or editing occurred (unless noted).

Author Information

The best has been done to ensure that the author’s work has been kept as it was found. Some pages were destroyed before the editors of this collection could rescue them.
