An entry in the Seventh Sanctum's Tarot Contest
.The Philosopher of Chains
symbolizes the dangers of narrow-minded thinking, and the constraints of the human mind. When upright, it signifies a mental block of some sort on the part of the querent - an obstacle preventing his or her creativity from flourishing. This most commonly manifests as Writer's Block.
The card reversed signifies the opposite - an unfettered, open mind, possibly even chaotic in its lack of restraint. This can mean one of two things: a period of extremely vivid imagination, or a degeneration into madness.
Alternately, it could just be a small rectangle of paper with a chained-up sophist on it.
