Overly Broad or Narrow Definitions
A definition is no good if it defines its subject with overly wide or narrow parameters. For example, "a shape with four sides of equal length" is not a good definition for 'square'. Why? Not only squares have four sides of equal length; rhombi do as well. This is proven by identifying not only the term being defined, but also the conditions in the definition. Likewise, defining a 'rectangle' as "a shape with four perpendicular sides of equal length" is not valid because it is too narrow.

Famous quotes containing the words overly, broad, narrow and/or definitions:
“Manners are of such great consequence to the novelist that any kind will do. Bad manners are better than no manners at all, and because we are losing our customary manners, we are probably overly conscious of them; this seems to be a condition that produces writers.”
—Flannery O’Connor (1925–1964)
“The hearts that would have given their blood like water,
Beat heavily beyond the Atlantic roar.
Fair these broad meads—these hoary woods are grand:
But we are exiles from our fathers’ land.”
—John Galt (1877–1957)
“... the outcome of the Clarence Thomas hearings and his subsequent appointment to the Supreme Court shows how misguided, narrow notions of racial solidarity that suppress dissent and critique can lead black folks to support individuals who will not protect their rights.”
—bell hooks (b. c. 1955)
“Lord Byron is an exceedingly interesting person, and as such is it not to be regretted that he is a slave to the vilest and most vulgar prejudices, and as mad as the winds?
There have been many definitions of beauty in art. What is it? Beauty is what the untrained eyes consider abominable.”
—Edmond De Goncourt (1822–1896)
