It’s because we associate so much with our experience as memories that makes us think that that is what we are. Are people with Alzheimer’s the same person? No, they’re different people. This is why we’re not allowed to just go around killing people with Alzheimer’s and dementia.
The thing that makes us alive is the constant change and activity in the body. If you say, someone does not change, that someone is the same throughout their whole life. That amounts to calling something dead, still, unchanging, lifeless.
These people with dementia, they still have a personality don’t they? I know my friend’s mother does. And my friends, father who died a few months back with Alzheimer’s. Yes, he was angry and had outbursts that were 100% uncharacteristically not like his old behavior. But behavior does not dictate who you are is signals that we still have a consciousness. And that is who we are. We are not our memories. We are not our current form of expression. We are our consciousness. Because our consciousness loses the function of accessing memories does not make us any more us.
You are not your memory. You are consciousness. You are the thing that reads memories.
But again, this drifted so far from the point of the article. This man killed himself not for his current suffering, but for his perceived future suffering. He was afraid of change he was afraid of what that change meant. He wanted people to see the same dead person That people saw him in life. A constant unchanging perception.
