The Allusionist is a show about words, but today’s episode isn’t looking at words themselves, but what’s on either side of them: that is, nothingness. 

If it weren’t for the absence of words, the words themselves would be rather incomprehensible - how do you know where one word ends and the next begins without the space between? 

Since the spaces serve such a crucial function in language, I was pretty astonished to discover they are a lot younger than language itself.
