#Id say, for example, roman number || is an abstraction of 2 objects placed in one time. I have || keys, I have || stars, etc.
Number 2 is an abstract. It can be-linked to 1+1 objects, like 2 cars or apples, however, in and of itself it has new and different characteristics. Its easier to talk of 2 as a prime than || because the idea and its embodiment provide new and unexpected realities that keep emerging through delving into number 2 rather than ||..
or am i over generalising??
