What does this song mean?

[coloradodem2005]

The more you see the less you know
The less you find out as you go
I knew much more then than I do now

Neon heart dayglo eyes
A city lit by fireflies
They’re advertising in the skies
For people like us

And I miss you when you’re not around
I’m getting ready to leave the ground….

Ooh ooh ooh
Ooh ooh ooh

Oh you look so beautiful tonight
In the city of blinding lights

Don’t look before you laugh
Look ugly in a photograph
Flash bulbs purple irises
The camera can’t see

I’ve seen you walk unafraid
I’ve seen you in the clothes you made
Can you see the beauty inside of me?
What happened to the beauty I had inside of me

And I miss you when you’re not around
I’m getting ready to leave the ground

Ooh ooh ooh
Ooh ooh ooh

Oh you look so beautiful tonight
In the city of blinding lights

Time… time
Won’t leave me as I am
But time won’t take the boy out of this man

Oh you look so beautiful tonight
Oh you look so beautiful tonight
Oh you look so beautiful tonight
In the city of blinding lights

The more you know the less you feel
Some pray for others steal
Blessings are not just for the ones who kneel… luckily

1. It's U2...

check your brain at the door.

2. That experience destroys innocence

and that nothing is ever quite the same the second or third time.

He plays with the cruel irony of finding something you love and then 'chasing the dragon' (trying to have an experience that equals the first). The 'blinding light' and various city light references reinforce the idea that romance is diminished by the more you can see, feel or know.
