You can’t have it both ways.

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

The saying is, ‘You can’t have it both ways,’ 17 (or 23,000 or infinity) ultimately breaks down to 2.

2 is fundamental. Because it represents choice.

1 is fundamental because it represents existence.

0 is fundamental because it represents the negative.

Back to the saying in the title of this blog post. ‘You can’t have it both ways’ is a statement worth noticing because making a choice from the 2 available options is a useful endeavour.
