Question Two [4 marks]: Symbolise the following argument in TFL: The sun is shining; well it appears that way to me. Even if my brain is hooked up to a computer that replaces all my senses, the words "the sun" and "shining" must refer to something. If we are living in a simulation, then instead of referring to a star and its light, those words refer to some data deep in the simulation software. But it doesn't matter either way! If they refer to that simulation, the statement "the sun is shining" is still true. And, as the great logician and terrible husband Alfred Tarski said, the statement "the sun is shining" is true if and only if the sun is shining. Here's a key to use: A = It appears to me that S. B = My brain is wired to a computer that provides all my sensory input. D= The terms "the sun" and "shining" refer to data in a computer simulation. L = The term "shining refers to starlight. M= We are living in a computer simulation. R= The term "the sun" refers to a star. S = The sun is shining. T= The statement "the sun is shining" is true. W = The terms "the sun" and "shining" refer to something. Question Three [2 marks]: Discuss one aspect of the argument that you had trouble symbolising. Explain why you used the approach that you did. Note that "because the textbook book [or Andrew] said so" is not an explanation
