   uneducated, ignorant, ill-informed person, Gr. 'idiw`ths,
   also and orig., a private person, not holding public office,
   fr. 'i`dios proper, peculiar. See {Idiom}.]
   1. A man in private station, as distinguished from one
      holding a public office. [Obs.]
      [1913 Webster]

            St. Austin affirmed that the plain places of
            Scripture are sufficient to all laics, and all
            idiots or private persons.            --Jer. Taylor.
      [1913 Webster]

   2. An unlearned, ignorant, or simple person, as distinguished
      from the educated; an ignoramus. [Obs.]
      [1913 Webster]

            Christ was received of idiots, of the vulgar people,
            and of the simpler sort, while he was rejected,
            despised, and persecuted even to death by the high
            priests, lawyers, scribes, doctors, and rabbis. --C.
                                                  Blount.
      [1913 Webster]

   3. A human being destitute of the ordinary intellectual
      powers, whether congenital, developmental, or accidental;
      commonly, a person without understanding from birth; a
      natural fool. In a former classification of mentally
      retarded people, idiot designated a person whose adult
      level of intelligence was equivalent to that of a
      three-year old or younger; this corresponded with an I.Q.
      level of approximately 25 or less.
      [1913 Webster +PJC]

            Life . . . is a tale
            Told by an idiot, full of sound and fury,
            Signifying nothing.                   --Shak.
      [1913 Webster]

   4. A fool; a simpleton; -- a term of reproach.
      [1913 Webster]

            Weenest thou make an idiot of our dame? --Chaucer.
      [1913 Webster]
    
from The Devil's Dictionary (1881-1906)
IDIOT, n.  A member of a large and powerful tribe whose influence in
human affairs has always been dominant and controlling.  The Idiot's
activity is not confined to any special field of thought or action,
but "pervades and regulates the whole."  He has the last word in
everything; his decision is unappealable.  He sets the fashions and
opinion of taste, dictates the limitations of speech and circumscribes
conduct with a dead-line.
    
from Bouvier's Law Dictionary, Revised 6th Ed (1856)
IDIOT, Persons. A person who has been without understanding from his 
nativity, and whom the law, therefore, presumes never likely to attain any. 
Shelf. on Lun. 2. 
     2. It is an imbecility or sterility of mind, and not a perversion of 
the understanding. Chit. Med. Jur. 345, 327, note s; 1 Russ. on Cr. 6; Bac. 
Ab. h.t. A; Bro. Ab. h.t.; Co. Litt. 246, 247; 3 Mod. 44; 1 Vern. 16; 4 
Rep. 126; 1 Bl. Com. 302. When a man cannot count or number twenty, nor tell 
his father's or mother's name, nor how old he is, having been frequently 
told of it, it is a fair presumption that, he is devoid of understanding. F. 
N. B. 233. Vide 1 Dow, P. C. now series, 392; S. C. 3 Bligh, R. new series, 
1. Persons born deaf, dumb, and blind, are, presumed to be idiots, for the 
senses being the only inlets of knowledge, and these, the most important of 
them, being closed, all ideas and associations belonging to them are totally 
excluded from their minds. Co. Litt. 42 Shelf. on Lun. 3. But this is a mere 
presumption, which, like most others, may be rebutted; and doubtless a 
person born deaf, dumb, and blind, who could be taught to read and write, 
would not be considered an idiot. A remarkable instance of such an one may 
be found in the person of Laura Bridgman, who has been taught how to 
converse and even to write. This young woman was, in the year 1848, at 
school at South Boston. Vide Locke on Human Understanding, B. 2 c. 11, Sec. 
12, 13; Ayliffe's Pand. 234; 4 Com. Dig. 610; 8 Com. Dig. 644. 
     3. Idiots are incapable of committing crimes, or entering into 
contracts. They cannot of course make a will; but they may acquire property 
by descent.
