If everything is constantly changing all the time, and you can't find essence or anything that lasts over time, how is it possible that memory exists?, and I don't talk about you remembering what happened years ago, I'm just talking about you remembering what happened a few minutes ago.

Yes, I would say so. The previous one dies time and again. The "me" entering a train is different from the "me" taking the seat in that very train.

If everything is constantly changing all the time, and you can't find essence or anything that lasts over time, how is it possible that memory exists?, and I don't talk about you remembering what happened years ago, I'm just talking about you remembering what happened a few minutes ago.

But I can't remember what happened three minutes ago. Not in its exact way. I just assume that similarity of the present situation is highly probable.

Try to re-catch what exactly you were thinking three minutes ago. It's impossible. You couldn't find the words in the correct order. So it's only the thought of having memory because of familiar thoughts and situations. Same with the body. If you walk through a room from one end to the other and I would ask you to take the exact same steps, you'd miss them, because memory does not provide for it.

Because if everything is constantly changing, nothing can rest for a second, because then there would be something static and there would be no change. Which means that we should be changing in every second, and that we would die every second and some new would take our place every second. Do you agree with that statement?

I agree with that statement though I do not know the time distance whether it's a second or less or more. Why must remain a "you"? What remains is consciousness not a conscious you, is how I see it. I think consciousness "exits" one moment after the other. Like walking through door after door after door. Doors and paths integrated in a kind of donut shaped universe where the consciousness can meet the subconscious.

If you learn a poem or a song and you say: I learned the lines when I was twelve. That is actually not correct. You started to learn those lines and from then on repeated them often enough as to remember them. Those things where we put deep enough tracks give chance to quickly trigger the matching sensations in brain and body. That "you" is long gone but the traces it left are not. So I think the present you picks up traces from the passed you and delivers them to a future you which anticipates both traces.

I think the present probably lasts as long as I clap my hand or snap my finger or play a flute or write this comment. When the flow is broken a new life starts all over :)

Yes, a pleasure. The questions you exchanged with me are of high value to me, for people have difficulties to come up with them. It's really helpful to talk to you.
