Seven year old child: I believe that Santa is Christmas, that Santa has magic that comes from Christmas Spirit, that Santa wants to give us all presents, and that if we are really good then he will! Hey Mopac, do you believe in Christmas?
Mopac: Christmas? Uh yeah, that holiday that people celebrate. End of December for some, beginning of January for others.
7YO: Well guess what, buddy? YOU BELIEVE IN SANTA! GOTCHA NOW SUCKER!
M: Uh, what? No, I don't believe that days can be magic or... what was that other thing you just said? Oh, the -
7YO: No no no no don't worry about that other stuff. Just the part where I throw a truism at you, that's all I want you to focus on.
M: But that part about presents... I don't believe that any -
7YO: No no no no you're really making this more complicated than it has to be. If I am in apologetics mode then when I say 'Santa' I really just mean that as a synonym for 'Christmas'. You aren't going to deny that Christmas is real like all those dirty wicked evil Hannuka celebrators do, are you?
M: I seriously doubt anyone has ever told you that Christmas does not exist.
7YO: It's settled then. Congrats on believing in Santa.
M: But that's not how language works, little kid. You can't just redefine the word Santa just because you want to convince people that they believe in him. The word 'Santa' has an actual meaning to people that speak this language. The meaning behind this word is how people understand this word to work and if you arbitrarily use it differently you aren't contributing anything to the conversation about Santa at all!
7YO: Actually I have a dictionary to support this definition of Santa.
M: Dictionary definition? Did you hear a single thing I just said? Even if you do have a dictionary which could be read that way I am telling you that people use the word Santa a certain way, a way that you understand perfectly well, and if you try to prove some point by just focusing on one aspect of it (the association between Santa and Christmas) you are not helping anything. There is so much more baggage to go with the word Santa than just what a dictionary says because that is how language works. Language is not created by dictionaries. Language is a social construct.
7YO: Look dude, seriously. Belief in Christmas is belief in Santa. I don't care what the other several billion people who speak English think about Santa because that is just their opinion. If the only part about Santa that you believe is the Christmas part, you don't believe in the presents or coal or anything, then to you Christmas is Santa. I wouldn't say that, I would say Christmas is just one part of Santa, but if Christmas is the only part that you believe in then I INSIST that you call Christmas Santa.
Mopac: That is absurd! I already have a word for Christmas. I call it Christmas!
7YO: Well sure you can still call it that, just make sure you call it Santa too and don't forget that if anyone asks you whether you believe in Santa you have to say yes now!
M: But that... That is so stupid... There are SO MANY flaws in what you are trying to do here that I -
7YO: Okay bye now! I am off to convince more people that Santa exists so that I can get on Santa's nice list! Bye bye Mopac!
- Later that same day -
Mopac: I believe that God is ultimate reality, that God created the universe, that God loves us all, and that the Orthodox Christian church is God's favorite church. Hey you, do you believe in ultimate reality?
Innocent bystander: Ultimate reality? Uh, you mean that like, reality is real? Yeah sure. Reality is real.
M: Well guess what, buddy? YOU BELIEVE IN GOD! GOTCHA NOW SUCKER!
IB: Uh, what? No, I don't believe that the universe was created or... what was that other thing you just said? Oh, the -
M: No no no no don't worry about that other stuff. Just the part where I throw a truism at you, that's all I want you to focus on.
IB: But that part about the Orthodox Church... I don't believe that any church -
M: No no no no you're really making this more complicated than it has to be. If I am in apologetics mode then when I say 'God' I really just mean that as a synonym for 'reality'. You aren't going to deny that reality is real like all those dirty wicked evil nihilists do, are you?
IB: I seriously doubt anyone has ever told you that they don't believe reality is real.
M: It's settled then. Congrats on becoming a theist.
IB: But that's not how... You know what, nevermind. I don't actually care. Congratulations Mopac I believe in God. Just let me get back to what I was doing.
