You are not expected to answer the questions in the reading! Soon I'll post a homework for Friday, and that will have questions from the reading.

Some have asked about past reading assignments. Reading questions become available when the homework is assigned, and become unavailable 10 minutes before the class they are due.

Homework 1: please do problems 4 and 5 of chapter 2 in the textbook. These are translations, to practice moving from English to our logical language. Hand them in at the beginning of class on Friday.

A few people asked me about translation keys. We've done examples in class, and there is one in the book, but here's the idea. By "translation key" we mean a translation from English to our logical language. Suppose we wanted to translate the sentence:
If Spongebob lives in Bikini Bottom, then Spongebob pays no property taxes.
You might have a key that includes the following:
Propositional Logic .............. English
P:            Spongebob lives in Bikini Bottom
Q:            Spongebob pays no property taxes
And then if you translated the sentence you would have:
(P --> Q)
Someone would be able to use your key to determine how to translate your logical sentence back into an English sentence.

So, for this homework, for the problem where you have to supply your own key, you'll write one answer key, which will have a column of atomic English sentences, and beside it a column of atomic logic sentences (P, Q, R....).

Reading: Read chapter 3 of A Concise Introduction to Logic. Before class starts, answer the questions on Angel.
