* reviewed our critical-thinking definition of a statement,
including its ought imperative and rhetorical question forms,
and some kinds of sentences that are NOT statements in critical thinking;
* NOW let's get back to ARGUMENTS
* an argument is a group of statements that include the following:
* one or more of this group of statements are intended as
SUPPORT for that argument. These SUPPORTING statements
are called PREMISES
* one statement is what the argument is intended to convince
or persuade. This statement is called the CONCLUSION.
* some examples of arguments (some adapted from
http://faculty.uncfsu.edu/jyoung/sample_arguments.htm):
* "Roger Maris held the single season home run record for 37
years, so he should be in the Baseball Hall of Fame."
* "A number of teenagers who committed violent acts spent many
hours playing violent video games; therefore, these games must
be more strictly controlled."
* "It was proper for the US to be involved in the Kosovo campaign,
as the US has a moral obligation to give assistance to people
subjected to inhumane treatment."
* "You should begin a daily program of exercise, because research
shows 30 minutes of exercise each day reduces risk of heart
disease."
* NOTE THAT, within the set of statements making up an argument:
* the premise statement(s) and the conclusion statement should
be RELATED or LINKED in some way.
* the premise statement(s) should be presented with the INTENT of
persuading one to support the conclusion statement
* the conclusion statement should be something DERIVED from the premise
statement(s), and not be a simple observation.
* the conclusion statement should NEED (or at least USE) the
premise statements in order to be argued effectively
* sometimes key phrases may HELP to identify a premise statement:
* since
because
for
seeing that
considering that
given that
inasmuch as
as indicated by
judging from
on account of
etc.
* sometimes key phrases may HELP to identify a conclusion statement:
* therefore
thus
so
accordingly
for this reason
that is why
as a result
this implies
hence
consequently
etc.
* what ARE some things (collections of statements) that are
NOT arguments?
* reports - convey info, but do not try to persuade
* unsupported assertions - a statement without premises, statements
that don't follow or imply any other statements.
* conditional statements - TRICKY!!!
* an if-then statement is a conditional statement
* illustrations
* explanations
...we will discuss these NON-argument types FURTHER on Wednesday;
