How can I find the phrase "liberated from shame and self consciousness" in The Lord of the Flies? Where does it appear?

Because there are many different editions of the novel Lord of the Flies, any quote that you're talking about might actually fall on different pages in different copies of the book. (Even though the text is exactly the same in each edition, the page sizes and fonts can be different.) This is true not only for old books like this one, but also for newer books that just happen to have multiple editions: large print editions, fresh editions with a movie image on the cover instead of the original cover, etc.

To find the quote you mentioned in any copy of the book, paper or electronic, head to "Chapter 4: Painted Faces and Long Hair." Now look in about the middle of the chapter for a paragraph that starts with the sentence "He knelt, holding the shell of water."

You'll find the quote in that paragraph. Here it is in a larger context, so you can see that it's talking about what Jack is doing with his mask:

"He looked in astonishment, no longer at himself but at an awesome stranger. He spilt the water and leapt to his feet, laughing excitedly. Beside the pool his sinewy body held up a mask that drew their eyes and appalled them. He began to dance and his laughter became a bloodthirsty snarling. He capered toward Bill, and the mask was a thing on its own, behind which Jack hid, liberated from shame and self-consciousness."

Of course, if you have an electronic copy of your book, you may be able to find a quote quickly by searching for it. If it doesn't work, try a shorter version of your quote or just a few key words from it. For example, if you were telling your ebook reader to search for the phrase "shame and self consciousness," then you wouldn't be able to find the quote--all because you were simply missing a teeny-tiny hyphen in the word "self-consciousness"!

If you don't have an electronic copy of your book and you need to find a quote quickly (without skimming for it forever,) then try Googling it instead. From your results, you might get at least a hint about where to look.

When you're looking for a particular quote, I'd be remiss if I didn't also suggest thinking first about what this phrase might mean in the story, which characters or events it might apply to, and then looking from there to see if that's where it is. That method is harder and takes more time, but it can work, too. For this example, you might ask yourself, "Who acts so bad in this story that he feels free from even being ashamed of how bad he acts?" You'd probably come up with Jack, and then you'd look for places where Jack is doing something awful.
