An argument
is a set of one or more reasons or objections bearing upon some claim.
Arguments have
a number of key components:
- A position
is the main claim under consideration. It can also be called the contention,
the conclusion, the issue, assertion, hypothesis or opinion: many different words are used in different contexts to describe it - and also other basic elments of an argument. The position statement must be an idea
that is debatable, that is some people will believe it to be true, while others
believe it to be false, or as yet unclarified. In Rationale we will represent a position with a white box:
- A reason
provides evidence that the position statment, or a secondary claim, is true. Reasons go in green boxes:
The Word "because" can have two uses in logical thinking
Note: The word
"reason" as used when talking about an Argument has a different
meaning than when it is used when talking about an Explanation. Explanations
are a big part of science, and explanations and arguments have lot in common.
As noted by David Kelley in his excellent book "The Art of Reasoning",
they have the same internal structure, and the logical relationships between
component elements are often identical. As he pithily says though:
"The difference
lies in their goals: an argument tries to show that something is true; an
explanation tries to show why it is true"
An explanation
might concern itself over why the sky is blue, whereas an argument
might try to convince us that the sky is a lonely place. As such, explanations
deal with "effect-cause" relationships rather than those between
"positions-claims".
We will discuss
this distinction more a bit later.
You will often
find it useful to double-check your arguments to see whether you have introduced
explanatory rather than argumentative elements.
There will be a quiz at the end of this Set on the difference between Arguments and Explanations.
