Awesome. I just overheard a conversation between a three year old and her mom at Linnea's:
"Mom—look at me."
"Yes?
[Pointing] "There are lily pads there!"
"There are, aren't there?"
"What are lily pads?"
"Well, it looks like they float, don't they?"
"But... why do they float?"
"So that they can get sunlight."
Now, this is awesome, because nobody uses the final cause to explain things anymore. I fully expected the mom to try to explain that things float when they are lighter than the mass of water they displace, etc... But, no. This lily pad floats for a purpose. It has a goal, a telos. It was designed that way.
