Argument from design
Proponents of teleology have argued against this objection on various grounds. For example, William A. Dembski says that such arguments are based upon presumptions about what a designer would or would not do, and so constitute a "theological rather than scientific claim." "Not knowing the designer," he continues, "they are in no position to say whether the designer proposed a faulty compromise among those [design] objectives." (Dembski 2004, pp. 58–9)
