6. Analyze the relationship between objects and their internal possibilities for combination within logical space.
7. Distinguish between a sign (the perceptible medium) and a symbol (the sign plus its logico-syntactic application).
8. Explain the role of Logical Syntax and Occam’s Razor in eliminating meaningless pseudo-propositions.
