Critics of intelligent design (ID) sometimes argue that if the human body were designed, it would be perfect. Among other things, we would not suffer from diseases such as cancer. Defenders of ID point out that this criticism is misplaced. Design does not imply perfection. Many things we know to be designed (such as cars) are imperfect. The “argument from imperfection” against ID is implicitly a theological argument, namely, that God is the designer and anything designed by God must be perfect. ID does not make that claim.
