Locke:What do you suppose is in this cocoon, Charlie?
Charlie:I don't know. A- a- a butterfly, I guess.
Locke:No, it's much more beautiful than that. That's a moth cocoon. It's ironic- the butterflies get all the attention, but moths, they spin silk. They're stronger. They're faster.
Charlie:That's wonderful but...
Locke:You see this little hole? This moth's just about to emerge. It's in there right now, struggling. It's digging it's way through the thick hide of the cocoon. Now, I could help it- take my knife, gently widen the opening, and the moth would be free- but it would be too weak to survive. Struggle is nature's way of strengthening it.
