Dear Eckard,
Greetings. Good to meet you again.
> I fundamentally disagree with your opinion that laws and things (map and territory) "become more and more like each other, until deepest down, they become one and the same".
Its perfectly understandable if we disagree. For me, this realisation - that maths is in the things -
comes as a relief! I have struggled between `Maths is invented/created by the mind' and `Mind discovers maths; maths is Platonic, and lives in a world which we have not witnessed for ourselves'. The former hard to believe, given the universality of maths; and the latter hard to believe, because I find it unscientific; let us not believe in that which we have no evidence for - Platonic maths. I feel the thing-law interpretation of neural pathways lends credibility to `laws are things'. Actually, I do not see this as taking away the freedom of mathematics.
> Is an evolving system shift-invariant at all? Are you really the same thing at all ages?
>My answer is yes in case of models but no in case of reality. To me, there is just one fix point in nature - the current border between the past and the future. Any counterargument?
I make a distinction between consciousness on the one hand, and the mind/brain/body on the other.The latter is a system, and I agree it is not shift invariant. The body, the mind, the brain, all change with time, and are different things at different ages.
But I do not consider consciousness / self-awareness as a thing or a system. It is the law aspect of a thing-law, with the thing being mind/body/brain. For me, the conviction that consciousness and mind are different only came through personal experience; and in particular from reading Eckhart Tolle's writings. One CAN watch over oneself, and observe one's thoughts and observe one's mind; and in principle achieve a thoughtless state (mind = 0); in this thoughtless state, consciousness remains. This consciousness is always in the now, and is in that sense timeless. Only the mind knows the past [memory] and the future [anticipation]. Consciousness knows only the present moment.
I fully agree with you that the `current border between past and future is the only fixed point'. To me, self-awareness permanently lives at this border. That is what makes me the same I that I was when I was ten years old, even though my mind, body and brain have all changed since then. I feel that is possible only because consciousness is not a thing, but instead, a law. That is why we cannot define it or grasp it or describe it, but only feel it.
I hope we will be able to agree on this point.
Thank you again for your interest in my essay. My best regards,
Tejinder
