Logic Syllabus
Course Description: In this course, we will study the concepts of formal and informal reasoning, including categorical syllogisms, propositional arguments, inductive generalization, analogical reasoning, causal arguments, inference to the best explanation, and informal fallacies. The objective of the course is to develop the students’ reasoning skills and their understanding of the methods of logical argumentation. Students will learn (1) how to judge the strength of claims and the quality of their sources, (2) how to identify different types of arguments, including their component parts and uses, (3) how to evaluate the quality of these arguments, and (4) how to formulate arguments that are both original and successful.

1. Exams and Quizzes: Almost one third of your grade will be based on 3 exams and 3 quizzes, which will include the sorts of problems found in the homework exercises as well as definitions. Cheating on tests will not be tolerated. Each student can only make up one exam or quiz (but not the final exam): You must have a valid excuse for missing the test (e.g., illness or family emergency; provide documentation if available) and make it up before the next session of class. Contact me as early as possible to make arrangements, prior to the scheduled exam or quiz. (Email or phone messages are acceptable for last minute occurrences.)
2. Homework
and Class Participation: There will be a homework assignment due at the
beginning of most class sessions. As in a math class, careful reading and
completion of the homework assignment before
class is very important because continual practice is essential for
mastering logic. Late homework will only be accepted for students who were
absent with a valid excuse, and must be turned in on the first day the student
returns to class. Students who are tardy will only receive half credit for
their homework. You are required to bring your book with you to class. Each student’s active participation in class
is encouraged and expected.
Homework Final Grade: A = 25 – 21 assignments,
B = 20.5 – 17, C = 16.5 – 13, D = 12.5 – 9, F = 8.5 – 0
3. Writing
Assignments and Argument Portfolio: I will assign a short writing
assignment on alternating weeks to give you practice analyzing, evaluating, and
formulating arguments, and to give you the opportunity to explore the relevance
of logic. These
writing assignments will culminate in a longer paper that explores the use of
logic in your major. In addition, students will be compiling a portfolio with
three original examples of each of the seven argument forms we will be
studying, plus three complex arguments. Students who fail to turn in either of these longer assignments will
not pass the class.
To ensure that students have adequate time to
do the reading and homework assignments prior to class, all written assignments
are due the day before class. Email them to me by 5 pm either Sunday or
Tuesday, starting the subject line of your email with “Logic sec. 1” or “Logic
sec. 3”, and bring a hard copy with you to class the next day.
Written assignments will be
downgraded for poor spelling, grammar, organization, etc., if they have more
than two errors per page. If you have difficulties in these areas, I strongly recommend
taking drafts of your papers to the
4. Attendance: Prompt and consistent attendance is expected and is
in your best interest because poor attendance and tardies
will inevitably affect your other grades in the course. Also, I will weigh
attendance heavily when determining final grades in borderline cases. Mastering
logic requires the sort of guidance and feedback that students only receive in
class. As a result, students who miss ¼ of the class sessions (7 absences) or
more for any reason (including illness) will not pass the class. If you
miss a class, I recommend that you make arrangements in advance to copy the
notes of another student.
Frequent tardiness and leaving early without
permission is rude and disruptive to the rest of the class. It is your
responsibility to arrange your schedule so that you don’t have any other
responsibilities during class time. After the second occurrence, tardies and leaving early will be counted as absences.
5. Extra Credit: For extra credit, students can formulate an original complex argument on a controversial topic, which, time permitting, we will evaluate in class. Consult with me before you start working on one of these assignments. No other extra credit work will be available.
All cell phones, music players, ear pieces/headphones, and other electronic devices must be turned off and put away during class time. I will consider requests to record the class or take notes on a computer (as long as the devices are only used for these purposes).
I strongly
encourage students with disabilities, including invisible disabilities such as
chronic diseases and learning disabilities, to discuss with me outside of class
appropriate accommodations that might be helpful to them. A student’s
disabilities must first be documented by the campus
