Ceiling fan installation

I plan on installing a ceiling fan in my living room. My wiring has 2 wires no ground. The house is 40 years old. Can I safely install the fan with light without the ground? If not what must I do? I do not have easy access to the area above the ceiling.

 

JUST A GUESS see if there is a double insolated fan that dont require a ground.
But 40 years ago they didnot have ground on any light fixture, NOW they all have em.
I had same problem in my kitchen, I GOT LUCKY & I DO NOT, DONT, OR EVER WIL I SAY I DID THE FOLLOWING (opps!guess i did)
I connected as if I were fishing new wires through conduit like they do. BUT WITH OUT THE CONDUIT. I taped the proper wireing to the old wires at the switch side and pulled like holy he-- WITH HOPES the wire would go through to the light fixture box with a little back and forth motion. the light fixture box was replaced with a ceiling fan box with expandable brace.
I DONT RECOMEND THE ABOVE BUT I HAVE A GOOD INSURANCE COMPANY.

Look into wire mold some are flat and paintable.

( to all the PRO's please dont get on my case too much about this. it was stupid to do but it worked )
