The Ring's Origins Come as a Bolt from the Blue / Lockhart's Classes Are Great for Earning Points

"I think... the answer is a cycle, with no beginning." After thinking for a moment, Luna Lovegood answered seriously.

"Incomplete."

Hearing the door knocker's judgment, Luna turned to Harry, looking somewhat puzzled.

She was certain that her answer could not be wrong, so why had the knocker responded like that?

It was neither correct nor incorrect, but... incomplete?

"Hmm... questions like the phoenix and fire, or the chicken and the egg—I was asked one last year too." Harry smiled as he explained. "After I talked with the knocker once, it changed its answer."

"Changed... what does that mean?" Luna said, clearly unable to make sense of it.

"Which came first, the chicken or the egg? Both answers are correct." Harry spoke fluently to the knocker. "From the perspective of biology and genetics, if we regard chickens as modern multicellular animals, then the Doushantuo embryo fossils that mark the transition from single-celled to multicellular animals appeared 610 million years ago. In other words, the developmental mechanisms unique to the embryos of us multicellular animals gradually became established within eggs before the first multicellular animals hatched. Therefore, of course the egg came first."

"But if we shift the discussion to the level of Aristotle's theory of substance, and refer to its concepts of 'potentiality and actuality,' then the egg is potentiality and the chicken is actuality. Only once chickens exist can people determine that an egg is a chicken egg. In other words, potentiality can only be understood through actuality, so in that case, the chicken came first."

"What... was that just now?" Luna stared blankly at Harry, her large eyes full of confusion.

"What I just explained was science derived from wisdom."
