It's a natural order. Other orders my be imparted to the integers,
however they will not be as simple to describe within Peano's axioms.

They could be reversed in order, they could be made into two parallel
lines, one of even numbers, the other of odd numbers. They could
be put all odd numbers first with the even numbers coming after all
the odd numbers.

1, 3, 5,...
2, 4, 6,...

1, 3, 5,... 2, 4, 6,...

The main problem of philosophy is truth.
This is an attribute shared by the White-Lie House.

The main problem of art is art critics.

The main problem of eternity is it takes too long.
The main problem with infinity is finding room for it.

The main problem of nothing is there's nothing to it.
