- This is not a scientific argument, it is a theological one. It is not saying anything about design but about the designer.
- The examples offered are usually not bad design but a problem with our ignorance. We don't understand the design. If we understood the full function of the organ then the good design would be obvious.
- Features need to be considered together and not in isolation. It is not one aspect that is being optimised but several.
As an analogy consider a car, an object that is designed.
- Pointing out why you think a car functions suboptimally does not prove the car is not designed, it says that you think the designer did a poor job.
- Not understanding how spoilers work does not mean their presence is poor design, rather it reveals good design when you becomes aware of flow dynamics.
- Designing for speed and crash safety are competing themes. The fastest car may be unsafe in a crash. The strongest car may be slow. A car may be optimal for speed, safety, space, and fuel efficiency; though not maximised for any single one of these features.
