"Striving after knowledge is a most sacred duty for every man and woman who has surrendered himself to God."Most translations say every "Muslim man and woman" but I like the more universal translation better.
This is a quote from the prophet Mohammed.
It was this attitude that helped Islam outstrip the Christian West in science and culture for hundreds of years after Mohammed's death. I like the quote because it not only refers to learning as a "sacred duty" -- something that has never seemed be a part of most Christian doctrine, but also because it puts men and women on the same level.
It also contains a recognition that at the time it was written, humanity had a lot yet to learn about the world. And for those of us reading it today, it's a reminder that we still have a lot to learn.
