Here at Mytour, we absolutely love to throw our readers for a loop. We know you're here for both fun and learning; maybe it’s just our impeccable work ethic, but on certain days, we feel compelled to deliver much more than what you expected. Well, today is one of those days.
While you usually count on us for a welcome break from whatever part of the day you're in, today we’re offering a MASSIVE distraction from the rest of your day—and maybe even tomorrow. Here are ten concepts that will take some time to wrap your mind around. We still haven't fully figured it out ourselves, and we write about this stuff.
10. Philosophical Zombies
Have you ever been able to truly understand what someone else is thinking? How can you be sure? It's one thing to claim that we can't really know anyone's inner thoughts; it's another thing entirely to suggest that the person may not even have any thoughts for you to discover.
The philosophical zombie is a thought experiment used in philosophy to examine consciousness and its relationship to the physical world. While most philosophers agree that they don’t actually exist, here’s the intriguing idea: the people you encounter in life may function like non-player characters in a video game. They act as if they have consciousness, but they do not. They may cry out “ow!” when you punch them, but they experience no pain. They exist solely to guide your consciousness through the world, without any consciousness of their own.
The zombie concept is primarily used to challenge physicalism, the belief that nothing exists except for physical things, and that everything that exists can be fully explained by its physical properties. The “conceivability argument” asserts that anything we can conceive of is possible, meaning zombies are within the realm of possibility. The very idea of their existence—though highly improbable—raises profound questions about consciousness and its function, which leads us to the next topic.
9. Qualia
Qualia are essentially the direct, subjective experiences of another person. While it may seem simple to say that we can never fully know what someone else is experiencing, the concept of qualia (note that the term is plural; the singular is “quale”) delves much deeper than just that.
Take hunger, for example. We all understand what hunger feels like, right? But how can you be sure that your friend Joe’s experience of hunger mirrors yours exactly? We could describe hunger as “an empty, rumbling sensation in the stomach.” Fine, but Joe’s feeling of “emptiness” could be entirely different from your own. And then there’s the color “red.” Everyone knows what red looks like, but how would you explain it to someone who’s blind? Even if we break it down scientifically, discussing light frequencies and how we perceive the color, we still can’t know if Joe sees red the same way you see, say, green.
Now, here’s where things get really strange. One famous thought experiment on qualia involves a woman raised in a black-and-white room, who only experiences the world through black-and-white monitors. She learns everything there is to know about color and vision, from wavelength frequencies to how the eyes process color. She becomes an expert in all the physical aspects of color, knowing all the factual details about the subject.
One day, she’s released from the room and sees color for the very first time. In that moment, she discovers something about color that she had never known before—but WHAT is it?
8. The Descriptivist Theory
In the 19th century, British philosopher John Stuart Mill proposed a theory of names that held sway for many years—essentially, he believed the meaning of a proper name is whatever corresponds to that name in the external world; a simple enough idea. However, the theory runs into trouble when dealing with things that don’t exist in the external world, which would render statements like, “Harry Potter is a great wizard” completely meaningless according to Mill’s perspective.
German logician Gottlob Frege took issue with this view, introducing his Descriptivist theory, which asserts that the meanings—semantic contents—of names are composed of the descriptions tied to them. This allows for the sentence above to make sense, as both the speaker and likely the listener would associate the name “Harry Potter” with the description “character from popular culture” or “fictional boy created by J.K. Rowling.”
It might seem straightforward, but prior to Frege, philosophers of language didn’t distinguish between sense and reference. In other words, words inherently carry multiple meanings—the OBJECT to which the term refers, and the WAY in which it refers to that object.
Believe it or not, the descriptivist theory has been significantly challenged in recent decades, especially by American philosopher Saul Kripke in his book *Naming and Necessity*. One of his arguments (in brief) suggests that if the information about the subject of a name is wrong or incomplete, the name might actually refer to a completely different individual for whom the known information is more accurate. Kripke’s critiques only get more mind-bending from there.
7. The Mind-Body Dilemma
The Mind-Body dilemma is a key component of Dualism, a philosophy that posits there are always two distinct principles or entities in any system—such as good and evil, light and dark, wet and dry. These entities are thought to exist independently and maintain equal influence over the system. A Dualist perspective on religion might assert that God and Satan are opposing forces, whereas a Monist viewpoint may believe in only one or the other, or even that we are all one unified consciousness, while a pluralist view could hold that many gods exist.
The Mind-Body dilemma can be summarized simply: what is the relationship between the body and the mind? If dualism holds true, humans must be either physical or mental beings, but we appear to possess qualities of both. This raises a multitude of questions: Are mental states and physical states the same thing? Do they influence each other, and if so, how? What exactly is consciousness, and if it exists apart from the physical body, can it exist outside of it? What does “self” really mean—are you your physical body, or are you your mind?
The issue that Dualists struggle to resolve is that there’s no way to fully conceptualize a being that has both a body AND a mind, which might bring you back to the notion of philosophical zombies mentioned earlier. Unless, of course, the next example completely shatters all of this thinking for you, which it just might.
6. The Simulation Hypothesis
Ever since *The Matrix* hit the screens, many of us have occasionally wondered if we might actually be living in a computer simulation. It’s an idea that has become somewhat familiar, and while it’s a fun notion to entertain, it no longer shocks us. However, the “Simulation Argument” takes this concept and frames it in a way that will likely make your mind spin… and, well, it might just freak you out a little. We’re sorry, but you did read the title, so we’re not *too* sorry.
To start, let’s consider the “Dream Argument.” When you’re dreaming, you typically don’t realize it; you’re fully immersed in the belief that the dream is real. In this sense, dreams function as the ultimate virtual reality, proving that our brains can trick us into perceiving sensory input as our actual physical surroundings, even though they’re not. In fact, it’s practically impossible to tell whether you’re dreaming right now—or if you always are. Now, think about this:
Humanity will likely endure long enough to develop the capability to create computer simulations that host simulated beings with artificial intelligence. Telling the AI that it’s a simulation would undermine its authenticity. Barring any restrictions on such simulations, we will almost certainly run billions of them—for purposes like studying history, war, disease, culture, and more. Some, if not most, of these simulations will create their own simulations, perpetuating the cycle ad infinitum.
So, what’s the more probable scenario—that we are the FIRST root civilization to develop this technology, or that we’re just one of the BILLIONS of simulations? Naturally, it’s far more likely that we are a simulation—and if we ever do develop the capability to run such simulations, it will become virtually CERTAIN.
5. Synchronicity
Synchronicity, beyond being an excellent album by The Police, is a term introduced by renowned psychologist and philosopher Carl Jung. It refers to the idea of ‘meaningful coincidences,’ and Jung’s interest was partly sparked by a rather strange event involving one of his patients.
Jung had been contemplating the notion that coincidences which seem to have a causal connection are actually brought about in some way by the consciousness of the person perceiving them. One of his patients, struggling with unresolved subconscious trauma, had a dream one night about an insect—a golden scarab, which was a large and rare beetle. The following day, during a session with Jung, after recounting the dream, an insect suddenly flew into the study’s window. Jung caught it—a golden scarab, very unusual for the climate—and released it into the room. As the patient sat there, stunned, Jung proceeded to explain his theory of meaningful coincidences.
The significance of the scarab itself—the patient recognized it as a symbol of death and rebirth in ancient Egyptian philosophy—served as a powerful symbol for her need to let go of outdated ways of thinking in order to make progress in her treatment. This event reinforced Jung’s views on synchronicity and its implication that our thoughts and ideas—even those that are subconscious—can influence the physical world, manifesting in meaningful ways.
4. Orchestrated Objective Reduction
By now, you’ve probably noticed that many of these ideas are attempts to unravel the nature of consciousness. The theory of Orchestrated Objective Reduction (Orch-OR) fits into this pursuit, but it was developed by two brilliant minds from completely different disciplines—Roger Penrose, a British theoretical physicist, and Stuart Hameroff, a University professor and anesthesiologist. After years of independent research, they combined their findings into the Orch-OR theory.
The theory is an extension of Gödel’s Incompleteness Theorem, which revolutionized mathematics by asserting that “any... theory capable of expressing elementary arithmetic cannot be both consistent and complete.” Essentially, it proves the limitations of mathematics and any defined system. Penrose took this further, claiming that since mathematicians are “systems” and theorems like Gödel’s are provable by human mathematicians, the inevitable conclusion is: “Mathematicians are not using a knowably sound calculation procedure to determine mathematical truth. We conclude that mathematical understanding—the method by which mathematicians arrive at their conclusions regarding mathematical truth—cannot be reduced to mere calculation.”
This implies that the human brain is not simply executing calculations—like a computer, but much, much faster—rather, it is doing something entirely different. Something that no computer could ever replicate, a 'non-computable process' that cannot be captured by an algorithm. There are very few phenomena in science that fit this description; one example is quantum wave function collapse, but that opens up an entirely different set of complexities.
3. Lightness
If the idea of a Universe without a clear beginning or end, in which the same events carry eternal, unchanging significance, seems heavy, consider the philosophical concept of Lightness, which stands as its stark opposite. In a Universe where there is a definite beginning and end, where everything that exists will eventually cease to exist, everything becomes transient, and nothing holds inherent meaning. In this context, Lightness becomes the ultimate burden to bear—where everything is 'without weight... and whether it was horrible, beautiful, or sublime... means nothing.'
The above quote is from the aptly named 'The Unbearable Lightness of Being' by the reclusive Milan Kundera, who dives deep into this philosophy—though it's one we’re not sure we’d want to explore ourselves. However, Zen Buddhism embraces this concept and teaches us to rejoice in it. In fact, many Eastern philosophies view the recognition and acceptance of this condition as a path to perfection and enlightenment.
It seems it all comes down to your perspective, which, upon further reflection, might just be the very point of this entire discussion.
2. Eternal Return
There are several issues with the 'Big Bang' model of cosmology, one of the most notable being the possibility of a theoretical 'Big Crunch'—where the expanding Universe eventually collapses (the 'oscillating universe' theory), or the potential for the Universe to end in a heat death. One alternative theory that resolves these issues is the theory of Eternal Return, which posits that the Universe has no true beginning or end; instead, it recurs infinitely, having always been and always will be.
This theory relies on the concept of infinite time and space, which is far from guaranteed. Based on a Newtonian cosmology, at least one mathematician has proven that the eternal recurrence of the Universe is mathematically inevitable, and this idea also appears in many religions, both ancient and modern.
This idea is a cornerstone of Nietzsche's philosophy and has profound implications regarding our understanding of free will and fate. The thought of being eternally bound to space and time, destined to live and relive every moment of our existence throughout an infinite eternity, seems almost unbearable—until you consider what lies beyond that...
1. The Uncertainty Principle
Quantum physics explores particles (or possibly waves) so minuscule that the very act of observing or measuring them can alter their behavior. This is the core of the Uncertainty Principle, first formulated by Werner Heisenberg, which may provide an answer to a question that has perplexed some of you for a while.
This duality of quanta was suggested to help explain such phenomena. If a particle seems to occupy two positions simultaneously, or behaves as both a wave and a particle at different times, or seems to blink in and out of existence—things that are well-documented at the quantum level—it might be because the act of observation itself influences the state of what is being observed.
As a result, while it may be feasible to gain an accurate reading of one specific property of a quantum object (such as the velocity of an electron), the very method used to obtain that measurement (like firing a photon to intercept it) will inevitably influence other properties (such as its location and mass). Consequently, capturing a COMPLETE and precise understanding of the object's overall state becomes impossible—those other characteristics become inherently uncertain. Simple, right?
