Man Booker What purpose a book?

I've been thinking about why I read, and about why other people read. What really is the purpose? I started out with entertainment and enjoyment and then went onto:

instruction

education

inspiration

moralising

escapism

experimentation

story-telling

propaganda

recording history

boundary-pushing

conscience-raising

I'm sure I'll add a few more to this list.

But in the meantime, why do I read? Is it 'simply' for pleasure? If it is, is that enough? Should I not want to be educated? Should I not want my conscience poked and prodded?

I'm gonna give that some though and get back to y'all.
