Chapter Exercise

For conclusion a, one reason might be 'I want to improve my reasoning skills'. To unpack this reason requires that you consider why reading a book on critical thinking would help you to do this. In doing so, you address each of the issues raised by the conclusion. For example (in the form 2+3+4 —> 1):

1. I am reading a book on reasoning.

2. I want to improve my reasoning skills.

3. I cannot improve my reasoning skills without knowing more about reasoning.

4. A book is an excellent source of knowledge about reasoning.

For conclusion b, an initial reason might be that 'thinking better stops you from being tricked by clever advertising'. See how many different issues are involved that are quite distinct from the conclusion? Each must be covered in some way in the premises, for example (in the form 2+3+4+5 —> 1):

1. There are considerable benefits to be gained from studying how to think better.

2. I do not want to be tricked by clever advertising.

3. Clever advertising works by tricking you into buying products.

4. Thinking clearly stops you being tricked by clever advertising.

5. Studying how to think better does enable you to think clearly.
