A fairly common rejoinder to
atheists’ desire for concrete evidence to indicate the existence of a god is
something along the lines of “well, you believe in love, don’t you?” The
essence of the argument is that love, like god, doesn’t have any kind of
physical form, can’t be seen, heard, tasted, smelt, or felt, and yet pretty
much everyone (atheists included), believe that it exists. So, if you believe
in love, how can you not believe in gods? Or, conversely, if you don’t believe
in gods, how can you believe in love?
This is an equivocation. That’s when
you pretend that two things that share only a superficial similarity are
actually the same in order to apply to one of them an argument that only
supports the other.
You see, god and love are not being
said to exist in the same way, so the comparison isn’t actually valid. Love is
an emotional state. It is generated in the brains of individual human beings.
It manifests in people’s consciousness as a set of feelings. It manifests outwardly
only in the way that it compels human beings to behave, and we are able to
communicate to each other a shared understanding of how that feels and what
actions it motivates. We can monitor brain states and see, physically, how the
experience affects the brain. But love doesn’t have any existence outside of
that. I don’t think most people believe that love is a conscious entity
floating around in the universe doing things independently for its own reasons.
Now, you can accurately say that at
least some people experience a god as a set of internal feelings. And that it
manifest outwardly in the ways it compels people to behave. That we can
communicate a sort of shared understanding of how it feels and what actions it
motivates. We can even monitor brain states and see, physically, how the
experience affects the brain. But then we’re asked to accept that the god does have an independent existence
outside of that. We’re asked to believe that the god is a conscious entity floating around doing things independently
for its own reasons.
That’s where the comparison
completely breaks down. Evidence that is sufficient to believe in the existence
of an emotional state is not also sufficient to believe in the existence of an
independent conscious entity. They’re not even remotely the same thing. It’s
like asking us to believe unicorns exist because we already believe the color pink
exists.
Yeah, I believe in love. Just not
God.
