For next Tuesday’s class, read the following:

1.  Sections 2.1-2.2 (pgs. 25-35) of the Kearns textbook.

(This was also the assigned reading for today’s (Thursday’s) class.  Now that we’ve discussed Propositional Logic in class, you should go back and review these sections to solidify your understanding.)

2.  Lobner 4.2-4.3 (pgs. 62-73).

I’ve posted a short excerpt from another Semantics textbook (written by Sebastian Lobner) in the “Readings” section of the website.  It discusses how certain semantic relationships between sentences, such as entailment, can be modeled in Propositional Logic.

(Note:  section 4.2 of the Lobner reading uses some terms that you won’t be familiar with, such as “CoU” and “Principle of Polarity”.  Don’t worry too much about these…just make sure that you understand the terms “contingent”, “logically true”, and “logically false”.)
