NDT said something very similar in the Rationallyspeaking podcast with Massimo Pigliucci and Julia Galef. Massimo and Julia were clearly unconvinced by his rationalization, as I myself was, but they didn't seem to want to engage in a debate over it.
I like him. I'd rather have a beer with him than with Dawkins. But I also think he's utterly wrong. By trying to avoid being characterized the way he doesn't like he makes a characterization of atheism that is wrong. Factually and in fact semantically wrong. I can only describe his attempt at defending his position as "clumsy". Some of his statements from the video:
Neil Degrasse Tyson said:
The only "ist" I am is a scientist.
Later on, he describes himself as an agnostic. Ok, the suffix is different, but he clearly contradicts what he conveys with this statement.
Neil Degrasse Tyson said:
I don't associate with movements, I'm not in "ism". I just think for myself.
None of which has anything to do with whether he is an atheist or not. I don't associate with aesthetics much, but I'm brown haired, even if I don't like it.
Neil Degrasse Tyson said:
The moment someone attaches you to a philosophy or a movement, then they assign all the baggage and all the rest of the philosophy that goes with it to you.
Well, that's a very broad picture of what happens in our social exchanges, but I agree that it happens even if ironically he's making a gross generalization of it. At the same time, though, he has a choice to be explicit about what he is and what he is not regarding all the baggage. Example: Massimo Pigliucci is an atheist but he has criticized with passion other atheists like Dawkins or Harris. Whatever baggage there is with "atheism", it doesn't preclude Pigliucci or many other people from having a unique voice and think for themselves. Again, there's no argument supporting why he is not an atheist, just why he doesn't like its connotations.
Neil Degrasse Tyson said:
And when you want to have a conversation, they will assert that they already know everything there is to know about you because of that association. And that's not the way to have a conversation. I'm sorry, it's not.
Well, how about educating people on the meaning of "atheist"? It's pretty straightforward, and any person who understands logic is capable of understanding that most of that baggage NDT is so worried about doesn't follow from its definition.
Neil Degrasse Tyson said:
I'd rather we explore each other's ideas in real time, rather than assign a label to it and assert you know what's going to happen in advance.
Labels (aka concepts) have a purpose: communicate information. If a concept isn't clear enough for the purpose of the conversation, we always can switch to its definition. There's nothing about "labels" that prevents us from exploring each other's ideas in real time. They're just shortcuts for statements made of other labels.
Neil Degrasse Tyson said:
My stance on religion, or spirituality or God. If I'd find a word that came closest it would be "agnostic".
Oh no! A label with its own baggage! Maybe he likes the baggage better? Also, a contradiction with earlier arguments supporting why he doesn't describe himself as an atheist (it's an "ism", it's a label).
On agnosticism and atheism:
Neil Degrasse Tyson said:
No, they're not the same thing, and I'll tell you why. Atheists I know who proudly wear the badge are active atheists!
Well, yes. Tautologically yes. We could say that "active atheists" are "atheists who proudly wear the badge" and viceversa. The meaning is so similar that it looks nothing more than a circular argument. What about atheists? Nobody that I know claims NDT is an active atheist or an atheist who proudly wears the badge. Some just claim he's an atheist. He doesn't really address that. He doesn't even address its definition.
Neil Degrasse Tyson said:
It's odd that the word "atheist" even exists. I don't play golf. Is there a word for non golf players?
No. Nor is there an agnostic equivalent for that matter. He defeats his own argument by labeling himself as an agnostic. Concepts such as "atheist" and "agnostic" exist because religion has permeated societies in a way golf hasn't. It's not odd, but natural that new concepts emerge and become increasingly used at the same time new controversies arise. Golf isn't pivotal and controversial enough to warrant new concepts to describe adherence to it. Religion is, it seems.
