If you take the time, a google search for keywords like
bitcoin books site:bitcointalk.org would give you many previous answers for various levels of knowledge.
And, as already said, go to
https://bitcoin.org or the wiki
https://en.bitcoin.it/ and find your way. There's quite some info to assimilate.
If you have specific (non-philosophic) questions, do a search (since probably many others have asked that) and if nothing relevant found, ask.
