In predicate logic, an existential quantification is the predication of a property or relation to at least one member of the domain. It is denoted by the logical operator symbol ∃ (pronounced "there exists" or "for some"), which is called the existential quantifier. Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for any members of the domain.
Symbols are encoded U+2203 ∃ there exists (HTML: ∃
∃
as a mathematical symbol) and U+2204 ∄ there does not exist (HTML: ∄
).
Consider a formula that states that some natural number multiplied by itself is 25.
0·0 = 25, or 1·1 = 25, or 2·2 = 25, or 3·3 = 25, and so on.
This would seem to be a logical disjunction because of the repeated use of "or". However, the "and so on" makes this impossible to integrate and to interpret as a disjunction in formal logic. Instead, the statement could be rephrased more formally as
For some natural number n, n·n = 25.
This is a single statement using existential quantification.

There are,
So many hours in the day
I know I've got work to do but hey
My will to move or even use my brain
Is whethered by eternal english rain
And when the talk show ends I scream
Right at the screen for more pregnant teens
I can't fall asleep
It's almost 3
So I water the flowers out on the street
I spent 5 hours on the net
Last night
Avoidin' the monsters under my bed
With square eyes
How fun-fucking-tabulous it is
To be so scared of the dark like this
I know I've got work to do
It's a bitch
I'm staggering 'round
I can't find the switch
I spent 5 hours on the net last
Avoidin' the monsters under my bed
With square eyes
Now I dare not stick my feet off the end
In case they bite
And sing the monster song
La-da-dup-ba-da-bow-ah [x4]
There are,
So many hours in the day
To address this problem in some way
Some barbie doll talks of carb intake
I turn it off
There are
worse things than being too late
then you realize it's too late
Everything I do is such a waste
you don't I do
You've already eaten the bait
It's two too to easy
Shut up slow down and brace
I won't you will
Sand fleas at my place
So So So Sleazy
Cut up Cut out Face
Slips out
Sleeve
Engine Stop and Engine Go
No No No No
And I don't even wanna go
No No No
No Shit there I was more bullets in the air
Than air
Climb down gooseneck canyon
Fall asleep and stare
Throw in Europeans
Soaking clothes and hair
Throw up all my words now
Though I doubt
care
No Don't follow the trail of dead Armadillos
straight to New Orleans
Making miles moments
dragged around by my chain
no Big Sir won't falter
In a tin can avalanche
If your going down there
Three dead boys
vain
I don't wanna go I
I don't wanna go I
I don't wanna go I
I don't wanna go I
