3912 | I must exist in order to be mistaken, so that even if I am mistaken, I can't be wrong about my own existence [Augustine] |
Full Idea: Since therefore I must exist in order to be mistaken, then even if I am mistaken, there can be no doubt that I am not mistaken in my knowledge that I exist…. I know that I exist, and I also know that I know. | |
From: Augustine (City of God [c.427], Ch.XI.26) | |
A reaction: Fine, but the main problem is his over-confidence about a stable personal identity that does the thinking. |
