Course Description:

This course is an introduction to logic for students with no previous experience with the subject. Logic is the formal study of arguments, where argument is intended in a very specific sense. Whenever anyone puts forward a set of reasons for accepting a sentence, e.g.:

Most scientists are alarmists, so gobal warming is not a serious problem.

Or,

If Israel goes into the war, then the casualties will be much higher. But Israel will not go into the war, so casualty levels will be low.

they are providing an argument.
An argument in our sense is a sequence of statements, one of which is supposed to follow from, or be supported by, the others. In logic we are interested in characterising what makes an argument a good argument.

In this course we will
study the semantics and proof theory for truth-functional logic and first order predicate logic with quantifiers, concluding with soundness and completeness proofs.

Assessment

The subject is largely mathematical in nature and assessment in this course will be by way of 6 problem sets to be done at home (60%), and midterm (20%) and
final (20%) examinations. Problem sets should be turned in to your TA, not to Professor Russell.

Assignments for this course can be downloaded as .pdf files from the table below.

Policy on Late Work

Late work will incur a penalty at a rate of 20 percent of the total possible grade every 24 hours.

Academic Misconduct

It is very important that you understand the rules for collaboration on this course. You may work with other students in order to solve the problems in your take-home problem sets, in fact, this is encouraged. However each student must write up his or her own solutions alone. You may not do it with another student looking over your shoulder to correct you. You may not do this from notes which another student has made, nor may you make notes on another student’s written solutions. You may not lend or copy digital or paper homework solutions – at any stage of completion. Collaboration is, of course, completely forbidden during the midterm and final examinations. Sometimes it is unclear whether a hypothetical case of collaboration is permissible according to these rules, or whether it counts as misconduct, but it is your duty to ensure that ALL your collaborations are clearly permissible. One good way to do this is not to take any written notes whilst working with other students: use a chalk board or white board to work out ideas, or, if you use paper, dispose of the written solutions before you separate to write up your individual homeworks alone. The Grade Grinder incorporates sophisticated mechanisms for detecting plagiarism and I suggest you read about these mechanisms on the LPL website and in the LPL book. Students suspected of plagiarism or any other form of academic dishonesty or misconduct will be reported to the academic integrity officer for Arts and Sciences (currently Dean Killen), so that the incident may be handled in a consistent, fair manner, and so that substantiated charges of misconduct may be noted in students’ records.


Homework Assignments

Homework assignments may be downloaded from this table. Handwritten parts to be “turned in” go in the appropriate file of the “turn in” filing cabinent in the philosophy department office in Wilson Hall by 3.30pm on the day they are due. Files to be submitted via the Grade Grinder should be sent to your TA (not to Professor Russell) before midnight, so please make sure that you have entered the right email address in Submit.
