If there is no ior, or an ior of 1, fresnel reflection result in NO 
reflection at all. Fresnel reflection depend on a change of ior at the 
surface.
So, in this example, you NEED the iors.

No fresnel and no thansparency = ior have no effect.
Fresnel reflection ABSOLUTELY NEED an ior <> 1, normally larger than 1.
And, obviously, ior is essential if you want any refraction.

This sounds almost like a verse by Li Bai, also known in the West as Li 
Tai Po :-)

Indeed it could be but it is a thought from that great Glasgow poet, 
philosopher and aesthetic, Lobby Dosser.
Holding court in Wine Ally he would put the world to rights.

Alas! The time has been and past and are all of a memory.
As, is right of all things been and past.

The phrase means a vagrant. Someone who sleeps in the open close of a 
tenement.
