"There is some good in all evil, and there is some evil in all good,"
This is the epilogue for the famous children's book Where the Red Fern Grows. As a child I thought this idea had something to do with the yin and yang sybmol, and actually, after reading about it in college, I think I was right.
I also think that opposites are inherently interesting and sometimes scary to us all. Even now, I feel a bit scared by this epilogue. It reminds me of magic- things are not what they seem.
I think I should have appreciated magic more as a kid, because in the adult world, where magic is scarce, things are dull.
