I'm thinking that maybe there actually is no design. Maybe because we evolved in this environment we see the world as having design and thus make things with a design to match. If the world was totally different, if a tree looked like a tangled jumble of limbs similar to a tangled cord, and leaves were not all the same general shape , would we still call that a design because that's what we evolved in?
We would call it a design if it made
sense.
Human design uses things we've learned about the way the universe works to make things that serve a purpose. Basically, we sift through ideas until we come up with something that experience with reality shows us should work and that a real path exists from here to there. i.e., no magic poofing, a la, "I will mentally implant antigravity spheres into a cat. Thus, a design for a flying cat." That's not a design . There is just no path from here to there.
Because design is predicated on making things that work in reality, it has much in common with reality at its baseline.
Design : Concerned with getting from here to there.
Reality:
Is there. And the present came along a path from past; so there is always a path from here to there.
Design: Uses mechanisms learned from reality.
Reality: Its use of those mechanisms is where the designer learned about them in the first place.
Design: Concerned with an end product that works.
Reality: As far as life goes, anything unfit to survive, dies. That's natural selection. Nothing that is terminally broken survives. It's tautological.
So the reality of a purely natural universe is unliving things operating by a superset of the mechanisms a designer would recognize he uses, and living things that fit the same niche that a designer designs for (fit for existence within the natural laws of the universe).
And, funny enough, "design" is evidence
against supernatural influences.
Imagine you have a set of blocks in front of you. You want to make a castle out of them. But how do you do that if they don't operate by any natural laws?
You start to build your castle: three blocks turn into chickens; six burst into flames; one tries to sexually molest you; another starts laughing maniacally and converts its mass into energy exploding with a force of several tons of TNT, killing everyone within a two block radius.
See? It just doesn't work. "Design" is a meaningless concept in a universe that makes no sense because supernatural influences predominate. You just cannot get from here to there in an orderly fashion.
