I voted for “Remy’s Conscience”, and for a good reason…
The transparent form of famed (and since deceased) French chef Auguste Gusteau was, according to himself, a “figment of your (Remy’s) imagination”, implying that he was an imaginary figure from Remy’s perspective. An imaginary figure is usually an invisible character that can only be seen via a first-person view; in other words, only the “imaginer” of the figure can see that entity.
A hallucination, on the other hand, is, as described by Wiktionary, this:
“A sensory perception of something that does not exist, arising from disorder of the nervous system, as in delirium tremens; a delusion.”
A “delirium tremens” is, in turn, this (as described by Wiktionary):
“(pathology) A psychosis of chronic alcoholism, usually due to alcohol withdrawal, which can be fatal. Symptoms include sweating, tremors, terrifying hallucinations, insomnia, restlessness, disorientation and anxiety.”
(I highly doubt that Remy was a hard-core alcoholic, unless he had serious brain damage that remains unbeknownst to us to this day…)
A hallucination, therefore, is fairly similar to that of an “imaginary friend” in that only the individual who is hallucinating can observe the entities he/she visualizes.
Judging by the fact that we can all see Gusteau, we naturally assume that he must be a ghost or spirit of some sort. One of you guys mentioned that Brad Bird stated that Gusteau is depicted as a “sprite”, which could, I suppose, be classified as a spirit or soul of some sort. Then again, just because the audience can see Gusteau doesn’t mean that he is really there. The director (and other individuals, perhaps) probably decided to put him in for obvious reasons, the foremost being believability and emphasis. By enabling us to see Gusteau, we are led to believe that Remy is not simply crazy, even though he really is, in reality, conversing with thin air.
The reason I say that Gusteau is Remy’s conscience is because, for one thing, it becomes fairly apparent (near the end of the film and even throughout) that Remy is simply talking to himself, thus boosting his confidence by way of thinking what to do next via listening to his “conscience”.
The term “conscience” is further defined by Wiktionary here:
“A person’s moral sense of right and wrong, chiefly as it affects their own behaviour.”
This does seem to apply to the “imaginary Gusteau” on many levels, and this is especially emphasized near the climax of the film… when Gusteau and Remy converse in the cage…
“I pretend you exist so I have someone to talk to. You only tell me stuff I already know! I know who I am! Why do I need you to tell me?! Why do I need to pretend?!!” - Remy
“Oh, but you don’t, Remy. You never did…” - Gusteau
So, in a nutshell, Remy was talking to himself and building himself up throughout the film the entire time. He just didn’t realize exactly how knowledgeable he really was until that crucial moment in the film.
