Ah, Zarathustra - my first Nietzsche. Great book. As for an all round history of philosophy, you must be wise to look for such a thing, and the answer is yes. There are several great history of philosophy sets, and I definately recomend you get one. I'm not sure which one in particular to recomend - I have no idea what they would have in Turkey, or in what language you prefer to read. But really, and quality set of history of philosophy would be valuable to you.

For a quick introduction to some topics, Bertrand Russell's "The Problems of Philosophy" is great.

"i am not wise, i love wisdom" (Socrates, that quote is belived to give us the name "philosophers"
Philo-Love Sophy- wisdom).

I was five and a half years in the usa so i am capble of reading books in english.

Thanks.

When you are ready to get more in depth, I recommend Frederick Copleston's "A History of Philosophy".
