Erwin Schrödinger said this quote

No Self stands alone. Behind it stretches an immense chain of physical and - as a special class within the whole - mental events, to which it belongs as a reacting member and which it carries on. Through the condition at any moment of its somatic, especially its cerebral system, and through education, and tradition, by word, by writing, by monument, by manners, by a way of life, by a newly shaped environment... by so much that a thousand words would not exhaust it, by all that, I say, the Self is not so much linked with what happened to its ancestors, it is not so much the product, and merely the product, of all that, but rather, in the strictest sense of the word, the SAME THING as all that: the strict, direct continuation of it, just as the Self aged fifty is the continuation of the Self aged forty.
