That quote comes from the internalised conversation that Simon has with the beast within himself, during an epileptic fit. It is from chapter 8: Gift For The Darkness, a couple of paragraphs from the end, on page 158 in my edition of the book.
The beast has several names already in the book Lord of the Flies. It is initially referred to as a snake-thing or beastie. Later during his internalised conversation the beast is named as the Lord of the Flies. Finally the real nature of the beast is revealed as the darkness in the hearts of men.

It symbolizes the monstrosity and animalism of everyone on the island, when it was meant to be an offering to the beast. The beast was in all of them.
Simon is an epileptic and during an epileptic fugue he has an internalised conversation with the evil which he knows dwells within us all. He mentally projects this inner beast onto the pig's head on a stick which Jack has left as an offering for the imagined beast.

In Lord of the Flies there is technically no physcial beast. "The Beast" is a symbol for something greater i.e our inner savergery. Golding uses the beast as only a symbol which the boys seem to reconize even more with their desent into savergery
Some quotes from Simon in "Lord of the Flies" include: "Maybe there is a beast... maybe it's only us." "Fancy thinking the Beast was something you could hunt and kill! You knew, didn't you? I'm part of you?" "What I mean is... maybe it's only us."
In "Lord of the Flies," Maurice believes the beast is a physical entity that resides on the island and causes fear and chaos among the boys. He represents the belief that the beast is something tangible and menacing, reflecting the boys' inner fears and insecurities.
The Lord of the Flies, the pig's head on a stick in the middle of the jungle on the island, is used by Golding as a symbol. It is very similar to the "Beastie", in the fact that it symbolizes evil and the evil within everyone. This is primarily memorable during Simon's encounter with the Lord of the Flies. It's most memorable quote is, "Funny thinking how you though the beast was something you could kill!"

In "Lord of the Flies," Simon realizes that the beast is not a physical entity but rather a manifestation of the darkness and savagery present within each of the boys. He comes to this understanding after his encounter with the Lord of the Flies, symbolic of the innate evil that exists within humanity.
Simon is the only character who realizes that the beast doesn't exist and that the true beast is within themselves.

The boys mistakenly kill Simon, a member of their group, mistaking him for the beast during a chaotic and frenzied moment. Simon had come down from the mountain, where he had discovered the truth about the supposed beast, but the boys, caught up in their fear and mob mentality, attack and kill him.
Simon was mistaken for the beast in "Lord of the Flies". He was killed by the other boys during a frenzied tribal dance on the beach.
Beast only sings one song, "Something There".
