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:
“Somewhere between the overly intrusive parent and the parent who forgets about us after we’re out of the house is the ideally empathetic parent who recognizes the relativity of choice, the errors of his or her own way, and our need to find our own way and who can stay with us at a respectful distance while we do it.”
—Roger Gould (20th century)
“In America the taint of sectarianism lies broad upon the land. Not content with acknowledging the supremacy as the Diety, and with erecting temples in his honor, where all can bow down with reverence, the pride and vanity of human reason enter into and pollute our worship, and the houses that should be of God and for God, alone, where he is to be honored with submissive faith, are too often merely schools of metaphysical and useless distinctions. The nation is sectarian, rather than Christian.”
—James Fenimore Cooper (1789–1851)
““All day long from mid-day
We have talked in the one place,
All day long from shadowless noon
We have gone round and round
In the narrow theme of love
Like an old horse in a pound.””
—William Butler Yeats (1865–1939)
“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)
