There is just one thing which I loathe. Our experiences are unique. And such uniqueness... is unbearable in a philosophical standpoint.
Bare with me. Supporting my thesis will take a while.
What I mean is, that perception is merely our own "interpretation" of reality, and that interpretation differs from one person to another.
For example, "Color", as a concept, is only a natural consequence of having receptors that respond to "Color". To see the color Red means that a certain part of your brain notices that your eye is receiving a certain kind of stimulus, which for the concept of "Red", just so happens to be a certain frequency of the electromagnetic spectrum. If you don't have those receptors, then the concept of "Color" just don't mean anything to you. Yes, quantitatively, Colors exist as they are light waves, but the qualia of the concept of "Colors" is lost if you can't "experience" it. Which, if you will reread that last sense, is frankly tautological.
Take, for example, a blind man. You can try your best to explain light to them in a quantitative way, but they will simply never understand what it feels see color.
Now, what about those who have color blindness? People whose "calibration" of their color receptors are "configured differently"? Indeed, they also understand what Color is generally, but there are certain colors which they will simply never "understand" / "experience". And, if someone with Colorblindness and another with normal sight, look at the same picture or scenery, these two people may see two very different things. Yet you normally wouldn't know there is a difference between what you see and what others see. You tend to presume that others also experience the universe the way you do, and that how you think and how your mind works also apply to others.
Those examples above are merely benign, just to illustrate my point. But about its tremendous consequences?
What does it mean to know, that depending on the structure of one's brain, their vicariousness, their open-mindedness, they may simply just never understand what you know, feel, experience, and believe in?
As a child, I thought the world was a little bit simple. That people are logical, rational, beings. That people are literal minded. That, if you wish to be treated fairly, you must treat others fairly. That, if someone does you a favor, you ought to reciprocate them, out of gratitude and the kindness of your heart. That if there is a problem that affects humanity as a collective, we ought to work together to solve it. That pride, avarice, lust, sadism, arrogance, and other forms of abuse, manipulation, and exploitation of others are out of the question, because that just simply did not make logical sense. Why would you like to hurt others, if you do not want to be hurt yourself? Why would you like to gain so much money at the expense of the lives of others, at the expense of this planet? Why isn't everybody asking about fundamental questions about life, existence, nature, and philosophy? How can the vast majority of people continue on their normal paths of life, acting as if their existence is only in isolation, even if everything is interconnected? I don't understand selfishness. I don't understand self-centeredness. I don't understand obstinance and pride about learning new things. I don't understand petty pride and ego. I don't understand domination. I don't understand living under the constraints of society even if you know you are being exploited by those in power. I don't know how exploitation can be so normalized, we structure our daily lives as if that is merely logical (in Capitalism, 9-5 slave wages. in Authoritarian countries, no privacy and freedom). I don't know how can somebody live a life without being plagued by metaphysical questions such as, "Am I real?", "Who created us?", "What's the nature of reality?", among others.
Our experiences shape us. And, depending on one's influences and experiences, someone may or may not learn to self-reflect. Or even ask basic questions. And this is presuming that personality and thought process isn't genetic (aka, RNG). The very fact not everyone comes up with the same conclusions as I am, is already, well, quite depressing. While indeed it leads to individuality, but it also leads to people being absolute pricks, entitled, out-of-touch, sadistic, power-hungry, or whatever negative trait under the sun. People justify who they are based on their experiences, exacerbated by their biases in thought process.
So, why the tangent about perceiving colors?
I have aphantasia. I do not have a "mind's eye". I can't see anything inside my head; I only see darkness when I close my eyes. I don't have "imaginations" whatsoever. Also, I cannot conjure sounds and music inside my head. I can't "imagine" taste and smell. I can't imagine pain, discomfort, or nausea. But some people do. If this is the first time you have heard of this, and you also have aphantasia, well, ask people you personally know whether they can imagine things or not. If you don't have aphantasia, you might think I am crazy for having such a daily life drsastically different from you. But then again, it's like saying blind people are crazy because they can't see colors.
So, why again the tangent about aphantasia?
If something as benign as our perception and daily biological functions can be so drastically different, then what of the actual fundamental extrinsic differences between humans? How drastic would be our perceptions and interpretations of reality? How different is your version of "real" compared to "mine"? How does that affect our mutual understanding, if all of us has inherent biases that require years of introspection to dismantle? How does that affect objective reality? How are you supposed to change the world if there are people who are so oblivious about the world? What about differences in:
Culture.
Society.
Family.
Norms.
Country.
Beliefs.
Religion.
Knowledge.
Class / Wealth.
Environment.
Experiences. Heartbreak or a Happy Romance. Abuse or Care. Pain or Comfort. War or Peace. Poverty or Wealth. Uniqueness or Mediocrity. And more. So much more.
And it is just too much. Just too much. Even if I want to unlock the mysteries of the universe, it only takes just one powerful idiot to nuke the planet and we'll be back to the damn stone age once again. Or, even if we make a nation of materialists, it just takes another authoritarian idiot to commit mass genocide, and suppress intellectual progress for yet another millennium. This is a personal gripe towards the Romans and their descendants - man, if you guys just didn't kill Archimedes, we'd probably be living in Mars right now. And the "renaissance" is literally just bringing back the Arab's improvements over Greek knowledge back to Rome.
Anyway, I won't die on that hill.
Even if there exists objective reality, the very fact one's existence is naught but a mere figment of your imagination unless somebody truly cares about you, isn't exactly motivating.
And even if somebody does even truly care about you, it doesn't necessarily mean they wholly understand you. Because people are unique. You simply won't be able to fully understand another, well, unless they have a very literal mind as I do, which I bet will be very simple to translate to a sentient AI, well, relatively compared to Karens / Trumps / insert illogical person here.
And I haven't even mentioned neurodivergence and neurological disorders in this rant. Which is yet another rabbit hole.
