Atoms are 99.99% empty space. Solid objects aren’t actually solid, just tiny bits of matter floating in an electrostatic field.
Scouting is 99.99% values and ideals. Everything else is window dressing.
Take the space out of atoms and things turn into a little pile of dust.
Take the ideals out of Scouting and there’s not much left.
We can’t literally see the space between atoms; but scientific study provides evidence it is there.
We can’t literally see the values and ideals in Scouting.
The evidence they are present is the character we buid in our Scouts.
