* today (and Friday) - Chapter 7,
SUMMARIZING arguments
* then:
Chapter 15 - Science and Pseudoscience
Chapter 5 - Logical Fallacies I
Chapter 6 - Logical Fallacies I
***********
* we've discussed and demo'd DIAGRAMMING arguments;
NOW we're on the SUMMARIZING arguments!
* summarizing involves two ADDITIONAL skills
of argument analysis that we didn't get into
in argument diagramming:
* paraphrasing
* finding "missing" premises and conclusions
========
* paraphrasing
========
* in general: a restatement of something using
different words and phrases;
in argument analysis:
in particular, restating an argument in a
more STANDARDIZED, EASIER-to-ANALYZE format
* can include identifying and separating out
the premise(s) and conclusion,
can include restating the argument in simpler
terms;
* a GOOD paraphrase:
* accurate
* clear
* concise
* charitable
* more on ACCURATE:
* is FAITHFUL to the author's intended meaning,
reproduces that meaning fairly,
without bias or distortion
* more on CLEAR:
* we want to make the argument EASIER to understand
by our summaries and analysis, not harder...!
* (still being accurate, of course)
* more on CONCISE:
* a good paraphrase should capture the ESSENCE of
an argument;
* (but remembering that conciseness should NOT
override accuracy and clarity...!)
* more on CHARITABLE:
* when a passage can be interpreted more than one way,
the PRINCIPLE of CHARITY requires that we interpret
the passage as charitably as the evidence
reasonably permits
* don't interpret the argument to make it easier
to attack...
============
* finding "missing" premises and conclusions
============
* in real life, people often leave parts of their
arguments unstated;
* might be a premise, might be the conclusion!
* maybe it is considered obvious,
maybe an ad line is considered more effective without
it,
maybe the arguer is wanting to conceal a weak or
questionable step in their argument...!
* FUN NEW WORD of the DAY:
ENTHYMEME
* an argument with a MISSING premise or conclusion
* two BASIC rules for filling in the missing parts
of an enthymeme:
1. FAITHFULLY interpret the arguer's intentions
* the missing piece is a genuine part of the
argument ONLY if it was implicitly
understood to be part of the argument
by the arguer themself;
* question to ask:
"What else must the arguer assume -- that they
are not saying -- to reach their conclusion?"
2. be charitable
************
we'll summarize longer arguments using
STANDARDIZATION
************
* which will use the skills of paraphrasing and
filling in missing parts in enthymemes!
* STANDARDIZATION is restating an argument in
STANDARD LOGICAL FORM
* an argument is in STANDARD LOGICAL FORM
when:
* each step in the (restated) argument is numbered
consecutively
* premises are stated ABOVE the conclusions they
are claimed to support
* justifications are provided for each conclusion
in the argument
* for each conclusion or subconclusion,
indicate in PARENTHESES which previous steps
that conclusion or subconclusion is claimed to
follow from
* here are the steps to OBTAIN this form:
1. read through the argument, try to identify its main
conclusion
* then go back through the argument and identify
major premises and subconclusions offered in
support of that main conclusion
* paraphrase as needed to clarify meaning
2. omit any unnecessary or irrelevant material
3. number the steps in the argument, and stack them
in "correct" logical order (e.g.,
premises, then conclusion)
4. fill in any missing key premises or conclusions
* place BRACKETS [ ] around implied statements to indicate
that you added them
5. add parenthetical justifications for each
conclusion/subconclusion
* that is, for each conclusion or sub-conclusion, indicate
in parentheses from WHICH previous lines in the argument
that conclusion/sub-conclusion is claimed to directly follow
