I’m working on a philosophy question and need an explanation to help me learn.

Please answer the following questions:

1. If your friends existed only in your mind, who would you be talking to when you have a conversation with them? What do you think Berkeley would say?

2. Explain what you think Sartre would say about a person with an addiction. Do addictions prove that Sartre is wrong when he claims that people can freely decide which factors will determine their actions?

Please give substantial and thoughtful answers to each of these questions. No outside sources. Quoting the text is a good idea, but make sure to use in-text citation.
