Philosophy of Hume Discussion

pick and answer only one question pls

1. Hume, like Locke, is an empiricist.   What does Hume mean when he says that all knowledge comes from either ideas or impressions?  Namely, what is the difference between impressions and ideas? Explain his theory of ideas. Do you agree with it?  If you have objections to the theory, what are they, exactly? 

2. Hume insists that we cannot be certain of the future. This is often called the ‘problem of induction.’ What does this skepticism, amount to?  Explain.

3. Locke, recall, insisted that personal identity is our consciousness extended over time.  Hume, though, insists that because he can introspect no internal self, there is none.  So according to Hume, the self is an illusion.  Do Locke andIt i Hume really disagree about personal identity?

4. Hume, like Descartes, was not skeptical in his personal life. Namely, he believed in all sorts of things and acted as if he had knowledge.  Yet as he says, he did not believe or do anything them because he had good reasons, but rather because, naturally, his passions would override his reason.  In other words, nature overrides our skepticism.  Do you agree or disagree, and why?
