DAY 3

What Makes Me Certain That I Am

first asked by René Descartes
1637년(프랑스어 초판)
THE QUESTION ITSELF

When I doubt everything, what is the "I" that cannot be doubted?

THE QUESTION · ORIGINAL
Je pense, donc je suis (cogito, ergo sum)
📜 WHERE THE QUESTION WAS BORN

I think, therefore I am.

🌿The Lineage — How the Answers Split

Descartes deliberately doubted everything to find something certain — the senses, the world, even mathematics might be the deception of an evil demon. Yet even while being deceived, one fact stood firm: there is an "I" being deceived. Here the modern self was born. But rebuttal came quickly. Hume said that however hard he looked inward, he found no fixed "thinking self," only passing impressions. Lichtenberg quipped that we should say "it thinks," not "I think"; and Nietzsche called the subject "I" an illusion produced by grammar. The self that had seemed certain began to tremble again.

♾️ WHY IT STILL LIVES

Even now, when brain science and artificial minds ask the self anew, "what am I?" remains open.

📝I, Too, Stand Before It

When I first read this line I felt relief: even if all the world were a dream, the "I" that doubts it remains. But having passed through Hume and Nietzsche, I know that "I" is not as solid as it seemed. Close your eyes and search for the "thinking self," and all you catch are passing thoughts — the owner who holds them rarely appears. And yet something is here, right now, asking this question. Before that mystery I am still standing.
