The Case for Theism

[Angrboda]

When SETI engineers search for signs of intelligent life elsewhere in the universe, what are they looking for? The answer is surprisingly simple. They are looking for narrow-band radio emissions. This is because human beings build machines that produce these signals and, as far as we know, such emissions are not produced by mindless natural processes. The SETI engineers search for this signal, not because it is “complex” or fulfills some a priori criterion that would make it a “sign of intelligence,” but simply because they think they know what sorts of mechanisms are needed to produce it. This strategy may not work, but it is hard to see how the scientists could do any better. Our judgments about what counts as a sign of intelligent design must be based on empirical information about what designers often do and what they rarely do. As of now, these judgments are based on our knowledge of human intelligence. The more our hypotheses about intelligent designers depart from the human case, the more in the dark we are as to what the ground rules are for inferring intelligent design. It is imaginable that these limitations will subside as human beings learn more about the cosmos and the varieties of intelligence it contains. But for now, we are rather limited.
