The Divine Comedy - Gin-soaked Boy

I'm the darkness in the light
I'm the leftness in the right
I'm the rightness in the wrong
I'm the shortness in the long
I'm the goodness in the bad
I'm the saneness in the mad
I'm the sadness in the joy
I'm the gin in the gin-soaked boy

I'm the ghost in the machine
I'm the genius in the gene
I'm the beauty in the beast
I'm the sunset in the east
I'm the ruby in the dust
I'm the trust in the mistrust
I'm the Trojan horse in Troy
I'm the gin in the gin-soaked boy

I'm the tiger's empty cage
I'm the mystery's final page
I'm the stranger's lonely glance
I'm the hero's only chance
I'm the undiscovered land
I'm the single grain of sand
I'm the Christmas morning toy
I'm the gin in the gin-soaked boy

I'm the world you'll never see
I'm the slave you'll never free
I'm the truth you'll never know
I'm the place you'll never go
I'm the sound you'll never hear
I'm the course you'll never steer
I'm the will you'll not destroy
I'm the gin in the gin-soaked boy

I'm the half-truth in the lie
I'm the why not in the why
I'm the last roll of the die
I'm the old school in the tie
I'm the spirit in the sky
I'm the catcher in the rye
I'm the twinkle in her eye
I'm the Jeff Goldblum in "The Fly"

Who am I?
