I see the glass a hundred percent normaly. thanks to my imrpoved eye sight.

100% Full: 50% water and 50% Air

I see it as an opportunity to add vodka...

I see it 3 quarters.

I can't see glass. It's transparent.

I'd have to say *gulp* -- pour me another, barkeep.

This was most entertaining to read, thank you Sir.

Although I tend to agree with the majority of your analysis, I ask of you whether the inverse is true when we have a glass container that has an initial state of being full.

My example for this would be an underwater fissure of some kind that sits above a geothermal pocket. The heat rising from said pocket would heat the sand layer above it to the point of forming a glass receptacle which begins from a 'full state', being immersed in water. So if say the water is drained or evaporated away and said glass receptacle only contains water by 50% of its volume, could we now say that in this circumstance the glass is in fact half empty?

tl;dr A description of the state of fullness of a glass is dependant on it's initial state.

OK, let's see how complicated I can get this to be

For the sake of argument, I'm going to assume that we are talking about a glass in normal Earth atmosphere conditions in room temperature, and that "half full" means half full with some simple drinkable liquid like water. If we counted air to also trigger the condition of "filling" the glass, then the glass would be full at all times, which would make the question kind of silly. And also, I'm skipping the whole idea that this question is some sort of abstract metaphor for life - it's strictly the glass and the liquid.

I'd say that there's a more fundamental question to be asked first. Which is the default position of existence for this glass in question: filled with something or empty? The meaning why drinking glasses exist is because people want to have some better way of containing liquids and an easier way to drink then cupping their hands, trying to hold the liquid there and awkwardly pouring the liquid into their mouths. This notion of meaning of a drinking glass might make it intuitive that since glasses are made for drinking liquids, the default position is that the glass is full and can be emptied from that state.

But I disagree with this notion. When basic raw materials are formed into glassware meant for drinking, they don't form containing some liquid. Drinking glasses (and all glass containers) begin as a combination of extremely hot materials of some indeterminate shape. Later they are made into some shape by various means, slowly cooled down and only then can they be used to contain some liquid (and at least I store my glasses empty and fill them with something later ). Since all glasses begin their existence from this state, I'd argue that the default position for the glass is to be empty.

Every drinking glass begins it's existence by being empty, waiting to be filled. The glass can be both filled half way, and it can also be filled to the brim and then emptied half way. But the default position for the glass remains to be empty in all situations. Even in the latter case of first filling the glass to the brim and then emptying it half way, the default position is to be empty. The glass began by being empty, at some point in time it was filled completely, and it was then drained to be only half full. I'd say considering the default position and it's implications has given us the answer.

To answer the question: the glass is unarguably, undeniably and unchangeably half full, period.

Have a nice day

I guess i'd see it as half empty

i see it half...mostly cause it's a shot glass and i already had 3

Stop being cliche Quantum.

Full. Half full of water, half with air. Meaning it is infact 100% full.

EDIT: I accidentally a letter.

0.5

*Sings*
The window!
The window!
The second story window!
With a heave-ho and a mighty throw,
He threw it out the window!

I say, personally.
That this cup is a gift from Pundanar, no a test.
I must throw it out the window if I am thirsty, and drink it if I have to pee.

During my summer, all I will be thinking about is water... won't matter if it is in a cup, bottle, bowl, bedpan...

Who cares about a cup of water? I've got a life ahead of me and I won't waste it staring at water.

What? Oh... I thought signatures were supposed to express yourself. Don't see you having much personality...

I think this glass cup is half full, half empty, and all other possible measurements. All at the same time. Schrodinger's glass.

No, wait.. I found the cup. It's full of air.

My brother says:
Pessimist: Half empty. Like me.
Optimist: Hey, at least it's got half!
Him: Half full? Room for vodka!

no promise :3

Meh, I'm getting some sleep for once. Uh, stay in school......don't do drugs? Oh and stay on topic!

Its actually full Half air Half water. Problem solved.

*Brrztt* Guys? Guys? GUYS!? GUUUYYSS!!

GAME OVER.

Woops! *hops back on topic* Er, the glass is half full because who drinks half a glass of water and leaves it? Guys?........GUYS?

I See a Glass half-Full of intergalactic alcohol.The other half was injected into the quarian suit through an "emergency induction Port".

Well I'm 999, 1000 in 2 days. Problem?

Meh. Some sweet-sixteen I'm gonna have.

bnrdhduTo get back on subject, either way, half of this drink is sad. Because it means that you have drunk half of it, and it will soon be gone, or you didn't get a full glass.

I'm fifteen, sixteen in a few weeks. Who cares?

Well then, minecraft is a BA improvement on the wannabe Roblox.

Roblox came before Minecraft. I'm almost 12, thank you.

Roblox? That's a cheap knockoff of minecraft.

To get back on subject, either way, half of this drink is sad. Because it means that you have drunk half of it, and it will soon be gone, or you didn't get a full glass.

For you.

That is completely understandable. Most people can't stand my good looks and wit.
