hello lisa,
Welcome to mind brain.
Rather than try to write something myself, I did a search on Google, my favourite Search Engine for finding anything on the web.
If you don't know how to find google, just enter
http://www.google.com/ in your address bar, and hit Enter or whatever you do to call up a site.
When Google comes up enter 'philosophical ideas' without the quotes.
Google will come back with many sites; some are easier to read than others. Just click on any of them and have a look.
One good one is

All the best Bill.
