 Roster and Adds
 If space permits, I will add at the end of class today
 Review of Handouts and Course
Website
 My comments and your questions about the content of this course

 We have one text (described in the
Course Description), but will also be using a website – more on that later
 This is a skills-oriented class. Assigned or not – plan on using all exercise opportunities you can access (text and website).

All chapters and sections are from Hurley’s A Concise
Introduction to Logic (10 th Edition)
Come prepared to discuss assigned chapter/sections during the indicated weeks.
It’s easy to forget assignment due dates, especially for the online homeworks.
Create some system for yourself that will keep you on track.

 Homeworks are completed and submitted online
 Quizzes are taken and submitted in class
 Classwork is completed and submitted in class
 A Portfolio is compiled during the semester and is due in June.

Think of this as an ongoing record of your work in this course.
The portfolio will cover three modules – the basics of logic, propositional logic and categorical logic.
It may be submitted electronically (Powerpoint or other web-enabled presentation project) or physically (set of printed pages)

There is no extra credit. Instead, I will drop your lowest quiz and homework grades.
Lateness:
No late classwork
Late homeworks (done online) are penalized 10% for each day late.
Only one makeup quiz will be offered to those who miss a quiz for documented reasons.

 Hey, we all argue, right?
 The Argument Clinic
Logic deals with a different kind of argument…

 Reasoning is the process of moving toward conclusions on the basis of clear, compelling and relevant supportive statements.
 In much of logic, attention focuses on how we draw conclusions from statements, not on the truth of those statements.

 Those who oppose same-sex marriage are simply Neanderthals.
 Everybody knows same-sex marriage is a threat to society.
 So, same-sex marriages should be allowed.
 Opposition to same-sex marriage relies on constitutionally suspect reasoning.
 There is no clear evidence that same-sex marriage is a threat to society.
 So, same-sex marriage should be allowed.

 Any law or policy that limits constitutionally protected freedoms is unacceptable.
 Laws against same-sex marriage limit constitutionally protected freedoms.
 Support for this claim?
 So, laws against same-sex marriage are unacceptable.
