Analogies Are Not Arguments

Life is like a birdbath. It's made of concrete, filled with water, and uh...birds like to splash in it. Boy, that was dumb. Life isn't anything like a bird bath…

I have noticed a recent trend here on Quora (although it has probably been going on since time immemorial) whereby theists try to prove the existence of God (or, at the very least, justify why it’s rational to believe in God) through the awesome power of analogy. Some examples of this are the following:

• "You can't see the air, but you know its around. Same goes for God."
• "You can't see electricity but you know it's around. Same goes for God."

The thing is, though, is that these are not actually arguments and are instead just analogies. Analogies are wonderful things in that they make it easier to explain and understand complex subjects. But analogies don’t actually prove anything or provide evidence of anything and are really only useful if both of the following are true:

1. The underlying concept the analogy is seeking to explain is actually a true concept to begin with.
2. The analogy is actually a good one, meaning that the comparison it makes is actually relevant (see the Garfield comic shown above for an example of a bad analogy).

The various “God” analogies described above fail for both of these reasons. First of all, they assume that God exists instead of offering any evidence to that effect and then expect the analogy to somehow convince people to accept that assumption. If you can’t first demonstrate that God exists in the first place, using an analogy to explain why His existence can’t be detected doesn’t really get you very far.

Second of all, of course, they are simply bad analogies. For example, let’s look at the “argument” that “you can’t see the air but you know it’s around” (presumably meant to prove that the same is true of God and the fact that we can’t see Him doesn’t mean He doesn’t exist). Let’s see how well our knowledge of air stacks up against theists’ supposed knowledge of God:

• We primarily know about air based on the writings of people who lived thousands of years ago, just like theists primarily know about God based on the writings of people who lived thousands of years ago. Oh, wait — that’s not true.
• We mostly know that air exists because people claimed to have actually seen it thousands of years ago, even though it’s completely invisible today, just like people claimed to see and talk with God thousands of years ago even though nobody sees him today. Oh, wait — that’s not true.
• We have hundreds of different, often conflicting, descriptions today of what air actually is and how it acts, just like theists throughout the world and throughout history have hundreds (if not thousands) of different, often conflicting, descriptions of what God actually is and how He acts. Oh, wait — that’s not true.
• We are completely unable to detect air via any scientific instruments whatsoever and therefore have to accept its existence purely on faith, just like theists are completely unable to detect God via any scientific instruments and therefore have to accept His existence purely on faith. Oh, wait — that’s not true.
• Although we can occasionally detect the effect air has on the rest of the world, we can’t do so in any sort of consistent manner since “air moves in mysterious ways.” So, sometimes when we blow into a balloon it inflates, but other times it doesn’t. And sometimes when we inhale the air fills our lungs, but other times it just refuses to enter. This is just like how theists are unable to consistently detect the effect God has on the rest of the world since “God moves in mysterious ways.” So, sometimes He heals people who pray for healing, but other times He doesn’t. It’s exactly the same. Oh, wait — that’s not true.

So, yeah. Not a particularly good analogy, sorry, and definitely not any sort of argument (valid, sound or otherwise).
