‘You can’t have it both ways,’ is a common saying and it suggests that duality is fundamental. We don’t hear, ‘You can’t have it all 17 ways.’

2 is fundamental. Because it’s the first position where there is choice.
1 is fundamental because it represents existence.
0 is fundamental because it represents non-existence.
Back to the saying in the title of this blog post. ‘You can’t have it both ways’ is a statement worth noticing because it reminds me that there is something really natural about duality and opposites.
So when there seems to be too many options, it’s useful to be able to break them down to 2.
