“Do the following quick exercise:
Go look at yourself in the mirror and ask yourself, “Who told me that that’s me?”
Seriously! Go do it right now.
If you’re a very rational, scientifically-minded person, or an atheist, this is the perfect exercise for you.
What evidence do you have that you are that thing in the mirror?
Seriously! I’m not kidding. This is not an armchair philosophy exercise. This is a hardcore science experiment.
How do you know what you’re supposed to look like?
Could it be that you’ve simply assumed that that thing in the mirror was you without actually investigating the matter?
Is there any scientific evidence whatsoever of how you are supposed to look like? How would you even make such a determination?
Can you recall how in your early childhood it wasn’t at all obvious that you had a body, knew it’s parts, or knew how it looked? Can you recalling having to acquire all those notions?
Now, notice that your mind will come up with all sorts of objections and rationalizations for why you really are that thing in the mirror.
But I hope you’re wise enough not to blindly trust that mind of yours. After all, isn’t that your biggest gripe with religious fanatics? That they blindly believe in unwarranted things… that they beg the question?
Well, watch out! Maybe you’ve been committing that very same sin your whole life. Which, by the way way, would explain that grudge you hold towards religion.
Who’s begging the question now? Oh, how the tables have turned! Oh, the delicious the irony! Oh, the hypocrisy of rationalism!
If what I say is true, can you begin to fathom the significance of it? Not philosophically, but ACTUALLY!”
