What are Ralph's internal and external conflicts in "Lord of the Flies?"

One of Ralph's external conflicts in Golding's novel
Lord of the Flies is trying to get Jack and his group of hunters to
realize the importance of maintaining order among the group and maintaining the signal
fire. Ralph feels that it's important for the boys to try to somehow keep the semblance
of life on land alive on the island by doing things they would normally do at home. For
example, the boys should maintain their hygiene and try to keep the camp clean. Also,
Ralph feels the priority should be to keep the signal fire going. That is the only way
they are ever going to get rescued. However, Jack and his hunters are of the philosophy
that the most important endeavor to be worrying about is hunting to provide food for the
group. Jack is trying to proliferate this philosophy among the boys, while Ralph is
trying to make the boys see things his way. It's a constant struggle for
Ralph.
