What “Esoteric” Really Means: A No-Fluff Guide for Modern Seekers

The world “esoteric” gets thrown around a lot these days. It used to be that you could use good ol’ elementary school vocabulary tricks like “context clues” to understand. But we’re using the word not just a lot, but in seemingly different ways.


What the heck does esoteric even mean?!


Great question! Simply put, "esoteric" refers to knowledge that is deep, profound, and requires study to truly understand.


Keep reading to get clarity on what the word “esoteric” actually means, the ways it’s used today, and how to make sense of some pretty basic esoteric concepts.


Remember: Words Matter
Words are important. Every word in every language has a purpose, a meaning. It’s why dictionaries are popular and in high demand. (Even if we don’t all reach for one when we really ought to!) If we’re trying to understand something–a difficult concept, the motivations for someone’s actions, why a friend just got angry with us–we have to first understand the words being used to communicate something to us.
When trying to understand what counts as esoteric and what esoteric really means, we’ll have to explore a few other words that help us make sense of all of it.


The Key Difference: Arcane vs. Esoteric

The words “arcane” and "esoteric" often get used as synonyms. In reality, their use is rarely identical in meaning.


When something is arcane, it’s a secret. Only a very few people know about something that’s arcane. In other words, if you can buy a book about it at Barnes & Noble, then it’s not arcane.


Meanwhile, “esoteric” is still used to describe something that’s limited to a select few. It’s not so much that it’s a secret, like with something arcane. Rather, something esoteric is usually treated as private or confidential. The word gets used a lot when describing a tool or knowledge for initiates of special orders or groups, which is where the two words get mixed up.



Esoteric More Generally

One of my favorite official definitions for “esoteric” from Merriam-Webster’s Dictionary is “difficult to understand”. In other words, esoteric knowledge or practices being something that few people know or understand is mostly because it’s difficult to know and understand in the first place.


That’s why we also use the word “esoteric” to refer to “special, rare or unusual interest[s]”. When my son gets really deep into explaining the intricacies of Minecraft world building, I consider that esoteric knowledge in that sense. Unless I’m willing to sit down, explore, and commit to learning the software and gameplay to that degree, that’s knowledge I will never possess.


Meanwhile, when I start talking about what I consider simple, straight-forward knowledge about Tarot symbolism or major astrological placements (e.g. Sun, Moon, Ascendant), I’m often quickly reminded that these are more scholarly, mystical, or hermetic. In other words, they’re esoteric.


Speaking of hermetic…


What "Hermetic" Adds to the Mix

If you’re curious about esoteric topics, then you’re definitely going to stumble upon the word “hermetic” and the name Hermes Trismegistus at some point.


Hermes is that fun, fast trickster god from Greek Mythology. But that’s not the same Hermes we’re talking about. Over time, as Egyptian and Greek cultures overlapped, the Greeks came to know the Egyptian god Thoth as “Hermes Trismegistus”. Things related to Thoth or things Hermes Trismegistus was believed to have done are called “hermetic”.

Things that are both esoteric (difficult to understand) and considered mysterious are hermetic.


What About Esotericism?

If you thought the word “esoteric” was confusing, then this could break your brain!


The word “estoericism” is categorical. It’s literally a wide variety of religious traditions grouped together for no other reason than that they have a shared cultural standing. (They’re the religious outcasts of society.)

Many such groups, considering the basic safety of their members, tended to be “closed groups”. That is, they require initiation and often make use of secret names, etc. to ensure the privacy of each member. Although, today, that’s becoming less necessary in many parts of the world.


The exact definition of esotericism is, annoyingly, elusive to this day. As scholars and societies argue, the basic definition expands to include more groups. Today, esotericism may include Zen Buddhism, Wicca, Theosophy, Kabbala, and many others.


But what all paths under the esotericism umbrella definitively have in common is the esoteric nature of their practice. These are not “sit in a pew and listen” or easily understood through 101 classes. They require practitioners to be studious, open-minded, and eager to learn no matter what setbacks they encounter. They are lifelong practitioners, not dabblers.


Metaphysics: The Philosophy Behind the Practice

Those who’ve known me for a long time know I like to use the word “metaphysical” every chance I get. I generally lump all my esoteric learning and practice under that term instead. That tendency of mine has to do with my heavy emphasis on science.


“Metaphysics” technically denotes an area of philosophy. Its focus is on the nature of reality–just like science–but is more about the abstract. That is, it’s those things we can’t objectively explain.


For example, I can objectively observe the growth of a plant and the variables that led to the growth of that plant. I can get “super scientific” with it and get all the way down to the atomic level and explain the chemical reactions taking place. Because we can observe these.


But no matter how much I learn and know in this way, there’s still unanswered questions. Why? Why does the plant grow? Why does it exist? Why do these variables specifically lead to its growth? What other variables could exist beyond my ability to observe? If I talk sweetly to it, will the plant grow faster or stronger? These questions are where we transcend from everyday science to metaphysics.


Because of this theoretical nature of metaphysics, many esoteric topics can also be described as metaphysical. It’s the “how and why” part of the esoteric practices. 


Diving Into the Esoteric

Now that you have a better understanding of what “esoteric” is, you can see there’s nothing scary or overwhelming about it. (At least, not generally. I imagine engaging in the esoteric can be quite terrifying to those who are effort-averse!)


As you continue to engage your curiosity through an exploration of esoteric topics, remember that you don’t have to learn it all. No one who regularly studies and practices esoteric things–not even me–has all the answers. There is no single, definitive source of all things esoteric.


And that’s a good thing. Because esoteric things are difficult to understand.
