Ever had one of those days where you feel like you’re the only real person in the world and everyone around you is just an elaborately choreographed troop of eerily lifelike robots? No? Just me then? Well, you may have been flirting with one of the strangest and loneliest philosophical theories out there – solipsism.

Solipsism comes from the Latin words solus meaning “alone” and ipse meaning “self.” Put simply, it’s the idea that you are the only existing mind or subjective reality. The external world, other people – merely figments of your imagination or dream-like constructs created by your singular consciousness.

Freaky stuff, I know. But hey, how can you be 100% certain that you don’t exist in a bizarre simulated universe like the Matrix, with all of reality simply coded illusions? Or what if you’re a lone brain floating in a vat of nutrients, fed experiences straight into your neural inputs by an unknown experiment runner? This line of skeptical thought is what leads some eccentric solipsists to their maddening conclusion.

To help wrap our heads around this bizarre philosophical brainfart, let’s use an analogy. Imagine you’re playing a rich, open-world video game. Within this digital environment, you control the protagonist and can perceive and interact with the simulated world around you. But here’s the mind-bending kicker – as the player inhabiting the character, how could you definitively know the game world ITSELF isn’t the only true reality? What if you’re a self-aware AI program within the game engine and everything outside the game is just…an incomprehensible illusion?

Logically proving or disproving these solipsistic thought experiments is maddeningly difficult. Good luck convincing that sentient video game character of the “real” physical world outside! Though to be fair, players do regularly commit acts of unmerciful coded devastation that must seem pretty darn existential from inside the game universe. Food for…thought?

While there have been a handful of famous solipsists throughout history like Rene Descartes and Edmund Husserl, the theory remains pretty roundly rejected by modern philosophers and scientists. I mean, it’s all a bit too singularly mind vs material world, you know? The general consensus is that objective reality and a shared external world can be consistently observed and independently verified – even if the true nature of that reality remains open for debate.

But hey, who am I to claim what’s real or not since I could simply be a hallucination in your currently perceived construct of existence? Mind freakin’ blown, right? Either way, solipsism remains a rather hilarious philosophical party trick to trot out to really bake your friends’ noodles from time to time. Simply deadpan that you’re unconvinced they’re real for maximum existential crisis effects.
