Everyone knows the line: cogito ergo sum. Descartes’ great party trick. A man alone in his study, fretting about demons, announces that because he’s doubting, he must exist. Ta-da! Curtain call. Except, of course, it’s less of a revelation than a conjuring trick: he pulls an I out of a hat that was never proved to be there in the first place. Thinking is happening, indeed – but who invited the “thinker”?

And let’s not forget the dramatis personae Descartes smuggles in for atmosphere. A malicious demon, a benevolent God, both necessary props to justify his paranoia and his certainty. Philosophy as melodrama: cue organ music, lightning strike.

Enter the Critics

Spinoza rolls his eyes. Doubt isn’t some heroic starting point, he says – it’s just ignorance, a lack of adequate ideas. To elevate doubt into method is like treating vertigo as a navigational tool. Error isn’t demonic trickery; it’s our own confusion.

Kant arrives next, shaking his head. Descartes thinks he’s proven a substantial “I,” but all he’s actually shown is the form of subjectivity – the empty requirement that experiences hang together. The “I think” is a necessary placeholder, not a discovery. A grammatical “you are here” arrow, not a metaphysical treasure chest.

Hegel, of course, can’t resist upping the disdain. Descartes’ I is an empty abstraction, a hollow balloon floating above reality. The self isn’t given in some solitary moment of doubt; it emerges through process – social, historical, dialectical. The cogito is the philosophical equivalent of a selfie: lots of certainty, zero depth.

The Insufficiency Twist

And yet, maybe all of them are still dancing to the same fiddler. Because here’s the real suspicion: what if the whole problem is a trick of language? English, with its bossy Indo-European grammar, refuses to let verbs stand alone. “Thinking” must have a “thinker,” “seeing” a “seer.” Grammar insists on a subject; ontology obediently provides one.

Other languages don’t always play this game. Sanskrit or Pali can shrug and say simply, “it is seen.” Japanese leaves subjects implied, floating like ghosts. Some Indigenous languages describe perception as relational events – “seeing-with-the-tree occurs” – no heroic subject required. So perhaps the real villain here isn’t Descartes or even metaphysics, but syntax itself, conscripting us into a subject-shaped theatre.

Now, I don’t want to come off like a one-trick pony, forever waving the flag of “language insufficiency” like some tired philosopher’s catchphrase. But we should be suspicious when our limited grammar keeps painting us into corners, insisting on perceivers where maybe there are only perceptions, conjuring selves because our verbs can’t tolerate dangling.

Curtain Call

So in the end, Descartes’ famous “I” might be no more than a grammatical fiction, a casting error in the great play of philosophy. The cogito isn’t the foundation of modern thought; it’s the world’s most influential typo.
