|Prepare: To prepare to respond to this prompt, make sure to read carefully over Chapter 3 and the required portions of Chapter 4. View the deLaplante (2013) video What Is a Valid Argument? as well as the other required media for the week. For more guidance about how to construct a valid argument for a controversial position, review the Constructing a Valid Argument video and the document How to Construct a Valid Main Argument. Based on the sources, create a deductively valid argument for the position you defended in the Week One discussion.|
|Reflect: To make your argument deductively valid, you will need to make sure that there is no possible way that your premises could be true and your conclusion false. Your premises must lead logically to the truth of your conclusion. Make sure that your argument is sound that is in addition to being valid, make sure that the premises are true as far as you can tell. If your argument is invalid or if it has a false premise, revise it until you get an argument that you can stand behind.|
|Write: Identify the components and structure of your argument by presenting your deductively valid argument in standard form, and explain how your conclusion follows from your premises.|
|Guided Response: Read the arguments presented by your classmates, and analyze the reasoning that they have presented. In particular, if you believe that their argument is invalid, explain a way in which it would be possible for the premises to be true and the conclusion false. If you believe that their argument has a false premise, explain why a reasonable person might take it to be false. Finally, see if you can help them to improve their argument. How can they alter their premises so that all of them are true? What might they change in order to make their argument valid?|
