"Kant described a mechanism as a functional unity, in which the parts exist for one another in the performance of a particular function.
An organism, on the other hand, is a functional and structural unity in which the parts exist for and by means of one another in the expression of a particular nature.
This means that the parts of an organism – leaves, roots, flowers, limbs, eyes, heart, brain – are not made independently and then assembled, as in a machine, but arise as a result of interactions within the developing organism."

If we try to cross this lake by following only the stepping stones that lead toward our objective, we’ll soon get stuck. But what if we let go of our objectives? What if we focused on trying to find new stepping stones instead? This is novelty search. Instead of looking for something specific, you look for something new.
Novelty search isn’t just random, it’s chance plus memory. Together, these ingredients do something interesting.
...Stepping stones are also combinatorial. Each new stepping stone we discover expands our potential to find even more stepping stones. Collecting stepping stones is a luck maximization algorithm. By collecting and combining stepping stones, we might arrive at our destination by accident, or somewhere more interesting!
And through their unremitting efforts they were able to acquire once again the knowledge and feeling that qualified them to return as full-fledged members of society...
Time passed with shocking swiftness, and soon the boy was thirty-two, the girl thirty.
One beautiful April morning, in search of a cup of coffee to start the day, the boy was walking from west to east, while the girl, intending to send a special-delivery letter, was walking from east to west, both along the same narrow street in the Harajuku neighborhood of Tokyo. They passed each other in the very center of the street. The faintest gleam of their lost memories glimmered for the briefest moment in their hearts. Each felt a rumbling in the chest. And they knew:
She is the 100% perfect girl for me.
He is the 100% perfect boy for me.
But the glow of their memories was far too weak, and their thoughts no longer had the clarity of fourteen years earlier. Without a word, they passed each other, disappearing into the crowd. Forever.
