Discussion #3

3). Pick one concept from the assigned reading (chapter 15), that we have not already discussed, that you found useful or interesting and discuss it.


This chapter in the book made it very clear about causes and effects. It has always been somewhat unclear to me what you can refer to as a cause and what you can call an effect. However, the example the book shows makes it easier for me. It uses a simple example of a dog waking up a person. Previously, I would have to think hard about the different ways things could be causes and the different ways things could be effects. However, the book laid it out to show that because Spot barked and then Dick woke up, Spot must be the cause of Dick waking up. It also showed me how normal conditions can help prove that one situation caused another. For example, Dick woke up at 3am and the dog was barking. He doesn't normally wake up at 3am so it must be because of the dog barking.

  1. Hi MyClass Online, I liked this chapter too. It helped me better understand cause and effects and how it works. Sometimes it is hard for me to really understand how something caused something else. And the example the book uses helped me understand it better, but I did think further about it and was wondering if Dick does not usually wake up at 3 am then Spot probably does not usually bark at 3 am which means he too normally is not up at that time so what caused Spot to wake up at 3 am and start barking. If the answer to what caused this could be determined then could we say that what ever woke up Spot and caused him to bark was what caused Dick to wake up at 3 am? It seems to me that you could just keep going back with what caused what to happen.
