CRITICAL NOTE III.—OF DEFINITIONS.
A definition, in order to be perfect, must include the whole thing, or class of things, which it pretends to define, and exclude every thing which comes not under the name.
CRITICAL NOTE IV.—OF COMPARISONS.
A comparison is a form of speech which requires some similarity or common property in the things compared; without which, it becomes a solecism.
CRITICAL NOTE V.—OF FALSITIES.
Sentences that convey a meaning manifestly false, should be changed, rejected, or contradicted; because they distort language from its chief end, or only worthy use; which is, to state facts, and to tell the truth. CRITICAL NOTE VI.—OF ABSURDITIES.
Absurdities, of every kind, are contrary to grammar, because they are contrary to reason, or good sense, which is the foundation of grammar.
CRITICAL NOTE VII.—OF SELF-CONTRADICTION.
Every writer or speaker should be careful not to contradict himself; for what is self-contradictory, is both null in argument, and bad in style.
