[The exercizes for Chapter 5 work fine for an online group, so I've made no changes -- Tom]
1. Let the group look back at Exercize 1 at the end of Chapter Two. Try to decide how many of the propositions there, which I then asked you to force into the two categories "meaningful" and "meaningless" might fit just as well into the category of Game Rules or the resultants of tacit (unstated) Game Rules.
2. Meditate upon the following quote from Lord Russell's Our Knowledge of the External World (page 24):
The belief or unconscious conviction that all propositions are of some subject-predicate form -- in other words, that every fact consists of some thing having some quality -- has rendered most philosophers incapable of giving any account of science and daily life.
Consider the subject-predicate form as a Game Rule.
3. Contemplate the following typical subject-predicate sentences: "The lightning flashed suddenly." "It is now raining out." "I have an uncontrollable temper."
Try to identify the subject, "it" in the sentence: "It is now raining out."
See how subject-predicate Game Rules influence the other two sentences. Can any of you restate them in more phenomenological language?
Does any of this help you see the trick in the two-heads (or infinite heads) argument?
Also, we are supposed to give each member of the group a chance to think of a new dualism for dividing up the 13 objects listed in Chapter Four. (The list, with links to photos, is here.) Mike Smith, a prolific recent commentator, has suggested dividing them into objects that can be used by themselves vs. ones that require something else for use.
