Reading. Read from Galileo's Two New Sciences: First Day, from pages 35 [73] to 44 [82].

This is the most important section, for our purposes.

Practice: answer the following question, either on BlackBoard or you can print your answer and bring it to class if you prefer: There are at least five arguments here against either infinitesimals or actual infinities. Describe one of these arguments carefully as a reductio ad absurdum argument. What is he trying to show? What is the assumption for reductio (the assumption of the opposite of what he's trying to prove)? What are the premises (the things he assumes). What is each step of Galileo's reasoning? What's the contradiction that he finds?

Due at the beginning of class: A quick homework. Give an example of a sentence for each of Kant's four kinds: a priori, a posteriori, synthetic, analytic. Each sentence example must be your own (no credit for an example we used in class). Then, can you give an example of an analytic a proiri sentence; an example of a synthetic a posteriori sentence; and a synthetic a priori sentence. (If you disagree with Kant's notions, consider yourself as trying to find examples that he would accept.) So, that's seven sentences in total.
