All Alone with Your Thoughts: Solipsism, Reality and the Lonely Universe
You know you are real. “Cogito, ergo sum” as the French philosopher said, “I think, therefore I am”. Or at least, therefore you are, for only you can be sure you think. The problem is, you cannot be sure anyone else thinks, or even that anyone else exists.
This is the problem of solipsism, that only one’s own mind is certain to exist, which therefore throws all conventional notions of objective truth and external existence out of the window. This philosophical quandary has intrigued thinkers for centuries, inspiring profound reflections on consciousness, perception, and the boundaries of human knowledge.
Bringing the discussion to the modern day, if we cannot definitively prove that other human minds exist or are also thinking, then by the same logic, we cannot conclusively determine whether artificial intelligences can possess genuine thought or merely simulate it convincingly. Could AI eventually be conscious of itself? Indeed, the gap between thinking and being conscious of oneself - whether AI or human -may be far more ambiguous than we assume, a distinction that dissolves under philosophical scrutiny rather than clarifying under it.
Understanding solipsism becomes essential not only for appreciating the historical development of Western philosophy but also for navigating contemporary debates about the nature of mind, the possibility of other minds, and what it truly means to be conscious in an increasingly complex world.
The Original Problem
How can you be sure that anyone apart from you is real? We could all be automatons, functionally indistinguishable from other people because of course, the very idea of “other people” might itself be false. We could look like you, act like you, talk and behave as you would expect others like you to behave. But that doesn’t guarantee we aren’t all pretending.
For that matter, how do we know that any of we perceive is as it really is? What guarantee do you have that the world (and the wider universe) around you is not just some gloss applied by your brain to an entirely different reality?
What objective evidence do we have of anything, really? We only know what we perceive, and we have no way of checking if what we perceive is objectively true.
A Very Lonely Existence
Solipsism is the philosophical idea that the only thing a person can be truly sure of is the existence of their own thoughts and consciousness. When one accepts this perspective, all external phenomena, everything we see, hear, and interact with becomes uncertain and potentially illusory. In essence, the only thing a person can be sure of is that they exist, nothing else.
The idea comes from the inherent limitations of human perception and the subjective nature of our experiences. Descartes, the 17th-century French philosopher summed it up best with his axiom, “Cogito, ergo sum” (I think, therefore I am). This emphasizes the undeniable certainty of self-awareness while casting doubt on the external world’s reality.
Solipsism challenges conventional notions of knowledge and truth, prompting individuals to confront the possibility that their entire reality may be a construct of their mind. It raises profound questions about the nature of perception, consciousness, and the boundaries of human understanding.
