= 8yn. 2. Illusion, Delusion, Hallucination. As now tech- 
nically used, especially by the best authorities in medical 
jurisprudence, illusion signifies a false mental appear- 
ance or conception produced by an external cause acting 
through the senses, the falsity of which is capable of de- 
deluvie 
tectlon by the subject of It by examination or reasoning. 
Tims, a mirage, or the momentary belief that a reflection 
in :i mirror is a real object, is an illusion. A delusion is 
a fixed false mental conception, occasioned by an external 
object acting upon the senses, but not capable of correc- 
tion or removal by examination or reasoning. Thus, a 
fixed Iwllef that an inanimate object is a living person, 
that all one's friends are conspiring agalnit one, that all 
food offered Is poisoned, and the like, are delations. A 
hallucination Is a false conception occasioned by internal 
condition without external cause or aid of the senses, 
such as imagining that one hears an external voice when 
there Is no sound to suggest such an Idea. If a person 
walking at twilight, seeing a post, should Mleve it to be 
a spy pursuing him, and should imagine he saw tt move, 
this would be an illusion ; a continuous belief that every 
person one tees Is a spy pursuing one, if such as cannot 
be removed by evidence, Is a delation; a belief that one 
sees such spies pursuing, when there is no object In sight 
capable of suggesting such a thought. Is a hallucination. 
Illusion* are not necessarily Indications of insanity ; delu- 
sions and hallucinations, if fixed, are. In literary and 
popular use an illusion is an unreal appearance presented 
in any way to the bodily or the mental vision ; ft Is often 
pleasing, harmless, or even useful. The word delusion ex- 
presses strongly the mental condition of the person who 
puts too great faith in an illusion or any other error : he 
"labors under a delusion." A delusion is a mental error 
or deception, and may have regard to things actually exist- 
ing, as well as to illusions. Delusions are ordinarily repul- 
sive and discreditable, and may even lie mischievous. We 
speak of the illusions of fancy, hope, youth, and the like, 
but of the delusions of a fanatic or a lunatic. A hallucina- 
tion is the product of an imagination disordered, perhaps 
beyond the Ixiunds of sanity ; a flighty or crazy notion or 
belief, generally of some degree of permanence ; a special 
aberration of belief as to some specific point: the central 
suggestion In the word Is that of the groundlessness of the 
belief or opinion. 
Poetry produces an illusion on the eye of the mind, as 
a magic lantern produces an illusion on the eye of the 
body. Macaulay, Milton. 
Dreams or illusions, call them what you will, 
They lift us from the commonplace of life 
To better things. Longfellow, Michael Angelo.
