You must have heard of the "glass half-empty or half-full test."Â Psychologists use simple tests like this to determine whether a person tends to be an optimist or a pessimist. Optimists will usually say the glass is half-full, whereas pessimists will usually point out that it's half-empty. Optimists tend to focus on the good: there is still water available to drink. Pessimists, on the other hand, see the negative: there is water missing from what otherwise could be a full glass.
Dumb question, I know, but the dumber the question, the smarter the answers. This article is a simple critique of this test and a lot of other things.Â
Humans perceive most of reality in terms of dichotomy: masculine-feminine, yin-yang, purush-prakriti, and now, full or empty. Existence comes with very defined labels and solid boundaries: what one can be and why not the opposite.
With time, we graduated to spectrums, gradients, fluid identities, and anti-definitions. But pop psychology is still stuck in its boxed-up ways, in this case asking you to slot yourself into the sunshine-laced smile of the optimist or the brooding corner of the pessimist. The problem isn't that the test wants to classifyâitâs that it classifies poorly
2. Anekantavada and Superposition
AnekÄntavÄda is Jainismâs metaphysical gift to the world: a doctrine that says reality is complex, irreducible, and cannot be fully grasped by a single perspective. The glass is half-full and half-empty and neither and both, depending on the nayaâyour standpoint.
SyÄdvÄda then follows conditional predication. Maybe the glass is half-empty from one angle, half-full from another. NayavÄda? Partial viewpoints.Â
In quantum physics, particles exist in superpositionâmultiple states at once until observed. Borrow that for philosophy, and you get a cognitive superposition: truth existing in overlapping, unresolved narratives.
The beauty of AnekÄntavÄda? It doesnât seek comfort in finality. It resists closures. No full stops, only semicolons. It isnât about closure, but complexity. And in that complexity, there is honesty.
3. Truth Without Context, the Problem of Metaphysics, and "Nothing Is True"
Letâs be blunt: you canât know the truth. Not because youâre not smart enough, but because no one is. Because the context is infinite, and our lifespans are not. Because truth without context is like a punchline without a setupâit falls flat. There is no intellectual shortcut to truth; the actual truth.
Science isnât true; itâs useful. It changes. Astrology isnât true eitherâbut itâs also useful, sometimes. Your name isnât the truth of who you are. Even the glass isnât just glass. Itâs a temporary arrangement of atoms in space, meaningful only because we decided so (as Sartre would say).Â
If the glass started empty and got filled halfway, itâs half-full. If it started full and lost water, itâs half-empty. If you donât know what came before, itâs both. Or neither. Context collapses meaning into precision. Without it, your judgment is guesswork, cosplaying as insight.
Metaphysics tried to get to the essence of being, but got lost in language loops. Martin Heidegger said that Being reveals itself only through our situated experience. We cannot step outside our historicity, language, and culture to access pure, context-free truth. Similarly, Michel Foucault showed how knowledge and truth are always intertwined with power relations and discursive formations, challenging the idea of neutral, objective truth. And, Ludwig Wittgenstein famously emphasized the role of language-games and forms of life in determining meaning. A statementâs truth value depends on the language and context in which it is expressed. Truth claims are not isolated propositions floating free; they are embedded in particular life contexts, cultural norms, and linguistic practices.
4. Experience, Conditioning, and Platoâs Cave
We already know how we perceive the world is largely the product of our lives or heard. We are all conditioned for certain behaviors, biased in our thinking and are expected to follow certain norms at all times for the greater good of society. What we think is not what we actually think, but mostly a mosaic of everything we have interacted with so far. Kudos to all the independent thinkers, and keeping bandwagon thinkers aside, our thinking is conditioned and hence predictable.
Think youâre original? Cute.
Someone raised on full glasses will see lack. Someone raised on empty glasses will see potential. The object doesnât change, but its meaning does. This is Platoâs Allegory of Cave all over again.Â
5. Distribution of Resources: Who Gets the Water?
Now let's upgrade the metaphor. Itâs not about what you see in the glassâitâs about who owns the glass, who poured the water, and who gets to drink it.
In a world where resources are finite and systems are rigged, optimism is a privilege. You think the poor are pessimistic because they saw a glass as half-empty? No, they just never had a glass. Or worse, they made the glass, filled it, and handed it over to someone else.
Not everyone has the luxury to debate metaphors. Some are just thirsty.
So, will the well-hydrated person get the half-full glass, or the one dying of thirst? Or will the water be dirtied so nobody gets to drink it? Or will somebody discover a whole new freshwater ocean?Â
6. Pick a LaneâOr Donât
And here's the kicker: most of life operates in superpositions. People, situations, and decisions âthey're rarely one thing. They're potentially many things, shaped by what we know, when we know it, and how we choose to interpret it. Everyone wants you to pick a truth; be a rebel, and choose nothing (and thatâs what I want you to do, so if you do that, youâll be under my instructions, and if you donât, then someone elseâsâitâs a paradox!). Truth is a political weapon.Â
With so many problems with subjectivity, nothing can ever be known.Â
Let go. Not of curiosity, not of critical thought, but of the illusion that youâll ever arrive at âthe truth.â
Truth is not a destination; it is a journey we have willingly or unwillingly embarked on, and there is going to be no fixed destination to this. Tear up the map. Burn the compass. Float and enjoy while it lasts.Â
Tear up the map. Burn the compass. Float.
You are not an optimist or a pessimist. You are the glass. You are the water. You are the one asking the question. You are half-empty and half-full.

Not as shedding my responsibility of trying to research and write actual facts, but more as an acknowledgement that there is always room to learn and there are better trusted sources of knowledge. Not as a disclaimer, but as an invitationâgo read them yourself. Form your own conclusions. Be your own contradiction. Donât believe everything you see online. Also, in no way am I claiming that I am not a trusted source; I am, I just donât know how much.)
