4th week discussion: logic
Note 1: You will not be able to post to this Discussion topic until you’ve
gone through all the Module lessons for this week.
Note 2: This topic closes at 11:59 pm on Sunday night. Please participate
in the discussion from Monday – Friday so that your classmates can
interact with you, your professor can provide real-time feedback, and you
can take off the weekend. Everyone’s a winner!
Greetings, logicians! You have three responsibilities
this week. First, here are some of the fallacies you
Table shows fallacies
ambiguity division composition
non sequitur distorting thefacts post hoc ergo propter
slope parade of horrors
straw man specialpleading begging the question
oversimplification red herring tu quoque
ignorance appeal to authority
death by a
or any other fallacy in
lecture notes or readin
1. Pick one of these fallacies or any other (no
repeats – pick one different from your classmates,
please!) and write a brief example of it and a brief
explanation of its fallaciousness. Your sentence
should have a false premise, factual error, or logical
inconsistency making it invalid or unsound.
The governor was an action movie star, all brawn
and no brains. How can we expect him to lead?
–> This is an ad hominem fallacy because it
impugns a person’s character (“no brains”)
without any evidence while also associating that
purported trait with an unrelated attribute (being
unable to lead).
2. Create either an unsound or a sound syllogism
based on anything you want. An unsound
syllogism must be logically invalid, factually untrue, or
both. A sound syllogism must be both logically valid
and true. After you write your unsound or sound
syllogism, state why the conclusion, major/minor
premises, facts, etc., are flawed or flawless.
I’m opting to write an unsound syllogism here…
Davis is a sub-par rhythm guitarist.
Davis is an English teacher.
Therefore, all English teachers are sub-par
–> Untrue factually about Davis 🙂 Moreover,
opinions can’t be proved. This is also invalid
logically, as it commits the fallacy of composition
wherein something true of one thing is spuriously
applied to all similar things. Therefore, this
syllogism is “unsound.”
3. What’s a real world example of a time when
you’ve seen ethos, pathos, andlogos in effect at
the same event or location? Think politics,
interviews, the mall… Share your example with the
For full points, respond meaningfully and
grammatically to the three prompts. You are not
required to reply to classmates, though you may.
Throughout the work week, please review my
feedback on your classmates’ discussion posts and
on your own. These writing exercises are public

writing techniques and revisions. Thank you!
