Q: Is our Universe real?
How do we know that what we see around us is the real deal, and not some grand illusion perpetuated by an unseen force?
A: This is a philosophical dead end, a skeletal horse that has been endlessly beaten by nihilists, skeptics, and Matrix fan-boys for far too long. Read some fucking Spinoza.
However, I would like to problematize the use of the possessive “our” in relation to the “Universe.” By placing the collective possessive before the noun “Universe,” you seem to open your text up to the possibility of possession. Possession, as you well know, can only be possible when the Subject integrates the Object into his/her own being. You seem to believe that the universe—the incomprehensible totality of everything outside of yourself—is yours.
You have fallen into solipsism. Please ignore all of your impulses, as they may damage the rest of us, who realize that we are isolated and alone in a hostile world.
