What's on your mind?

[Taylor]

What's on my mind at midnight, the dawn of the new calendar?

The 'me' as a baby in a photo album, the 'me' running around in elementary school, and finally the 'me' sitting there...they were all the same organism called Takeshi Kuanari.
So where exactly did the entity called 'me' exist?
In the past, people thought the soul existed in a person's heart. Descartes believed the soul inhabited the pineal gland in the brain. I wondered briefly if I only existed in my memories?
But if that were the truth, then if I lost my memory like the Kid, wouldn't that mean I was no longer Takeshi Kuanari?
For one thing, the 'me' that ran around in elementary school was composed of different molecules than the 'me' here. From a purely material point of view, my younger 'me' was entirely different from my older 'me'. Cells die and are replaced daily. Every cell that is replaced will also die.
Even so, the me of five years ago before and the me there were definitely the same. Then, just what was it that defined 'me'? And where did that 'me' exist?
