 Substance dualists believe that thinking is a function of a non-material, separately existing, substance that somehow “combines” with the body to make a person. So—the argument might go—making a body can never be sufficient to guarantee the presence of thought: in themselves, digital computers are no different from any other merely material bodies in being utterly unable to think. Moreover—to introduce the “theological” element—it might be further added that, where a “soul” is suitably combined with a body, this is always the work of the divine creator of the universe: it is entirely up to God whether or not a particular kind of body is imbued with a thinking soul. (There is well known scriptural support for the proposition that human beings are “made in God’s image”. Perhaps there is also theological support for the claim that only God can make things in God’s image.)
