Philosophy 8: Introduction to Logic

Course Information:

This course focuses on the basic elements of reasoning, analysis of language as communication, propositional and class logic, definitions and fallacies, induction and scientific methods.

The primary objective of the course is to help you improve your analytical skills and, more generally, to help you to reason well. Our course focuses on the elements of logic. We'll concentrate on arguments, because these are an important means by which we reason. We'll learn to recognize, analyze and evaluate arguments. We'll look at what distinguishes good arguments from bad arguments and what the most common fallacies are in arguments.

This is an online course. All homework needs to be submitted online. All exams are online except for the final exam, which will be given onsite.


A Concise Introduction To Logic: Selected Chapters for El Camino College (10th edition), by Patrick Hurley. Available only at the CEC Bookstore. The book comes with access to the Aplia website that we will use. The Hurley book is also available for purchase online at our bookstore (See or in digital form at Cengage at this URL. We're using an abbreviated version of the much longer and more expensive text. If you want to buy individual chapters from Cengage, you should get chapters 1, 3, 4, 5, and 6 and a CengageNOW Printed Access Card. However the card is so expensive if bought separately (more than $55.00) that the bundle at our bookstore is a much better buy. I highly recommend the CD-ROM, but don't require it.

If you purchase the print version of Hurley online, and have it sent to you, you may not have it in time to complete the homework for the first week of class.

There may also be one or more handouts distributed at our course website. And don't forget to read my notes in the various ETUDES “modules”!


There will be four examinations in the course, including the final exam. Together, these will comprise 80% of your final grade. The first test (15%) will cover assignments and lectures related to chapter 1 of Hurley. The second exam (15%) will cover the same materials related to chapter 3 of the text.  The third test (20%) will do the same for chapters 4 and 5.  The final exam (30%) will review some of the earlier material from chapters 1 and 3 and will also cover chapter 6, or as much of chapter 6 as we can complete. The first three exams are online, using ETUDES.

The final exam is on campus or elsewhere at a recognized college or university testing center with proctoring if prior arrangements are made by students with me and the testing center. See for a list of approved proctoring sites. Some college or university testing centers are not on this list. Note: Testing centers normally charge about $25 for proctoring.

You may use a dictionary during exams, but the tests are otherwise NOT open-book exams. The online tests are mainly multiple-choice exams. The final exam will have some multiple-choice questions and some short-answer questions.

Course Policies:

Letter grades will be assigned to exams and those letter grades, along with a letter grade for homework for the entire term, then become the basis for your course grade.  The assignment of letter grades for homework will be based upon these percentages of the maximum possible number of points:

·         A = 90%

·         B = 80%

·         C = 65%

·         D = 55%  

For example, if you have 585 points out of 650 for homework, then you would have an A. The B range will begin at 520 and the C range at 422 points, etc. 

The grading of exams won't use grade breakpoints that are any higher than those above, but they may be lower depending upon the difficulty of the test.

Other course policies are listed in the syllabus.


Before the term begins the syllabus will be emailed to members of the class  who send me their email addresses. It is also available at our ETUDES website.


Each week during the course there will be online assignments from the section exercises in A Concise Introduction to Logic. All homework assignments must be submitted through CengageNOW at in order to receive credit. See the course calendar below for the assignment schedule. The assignments for a particular period need to be completed before 11:55pm Pacific Time of the last day of the period. For example, during the first week there are two assignments and these need to be submitted by or before February 22 at 11:55 PM. There is no time limit on your work completing each exercise. You can stop working on an assignment, save your work, and then resume the assignment later as long as the submission deadline hasn't passed. These answers are scored. For most exercises, you'll see your score immediately after submitting the assignment. You can do almost all assignments a second time if you aren't satisfied with your score on the first try. 

Most of the questions in the online exercises are worth one point. However True-False questions are worth half a point each, and some of the more involved questions are worth two or even three points each. The course calendar indicates how many homework questions you'll be doing in each exercise and what the point value of that exercise is.

There are 697.5 total points for your homework, but I will base your grade on a percentage of just 650 points. In other words, if you miss a few assignments because of computer problems or illness, etc., your grade won't necessarily suffer. Your homework as a whole is worth 20% of your course grade.
