"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!
Years ago a friend of mine had a dream about a strange invention; a staircase you could descend deep underground, in which you heard recordings of all the things anyone had ever said about you, both good and bad. The catch was, you had to pass through all the worst things people had said before you could get to the highest compliments at the very bottom. There is no way I would ever make it more than two and a half steps down such a staircase, but I understand its terrible logic: if we want the rewards of being loved we have to submit to the mortifying ordeal of being known.
