Take pi as an example. This is a number that is directly related to the number 1 in that pi is the circumference of a circle with a diameter of 1. Since pi is famously irrational, there is no way of perfectly visualising this ratio. Thus, in a quantised universe, pi is an impossible number. Perfect circles don't exist. This is philosophy.

But 1 exists, and so does 2. No philosophy required, no mental gymnastics. Just quantised energy, actual physical matter.
