The world is given to me only once, not one existing and one perceived. Subject and object are only one. The barrier between them cannot be said to have broken down as a result of recent experience in the physical sciences, because that barrier does not exist.

About Erwin Schrodinger (1887-1961)

Austrian physicist who shared the 1933 Nobel for the wave equation that bears his name and the famous cat thought-experiment. Closely associated with Werner Heisenberg (matrix-mechanics rival who reached the same physics by different math) and Albert Einstein (his pen-pal on quantum interpretation). For an intellectual contrast, see Niels Bohr, Danish physicist and architect of the Copenhagen interpretation — Schrödinger's cat thought-experiment was specifically designed to ridicule Bohr's 'observer-dependent reality' reading of quantum mechanics — Schrödinger thought the Copenhagen interpretation was absurd; the cat was meant as reductio ad absurdum.

Understanding this quote

What it means

Reality isn't divided into two versions — one that objectively exists out there and one we perceive internally. We each encounter the world once, as a unified whole. The observer and the observed are inseparable; consciousness and matter aren't two distinct things bridged by perception. The division between self and world is a mental construct, not a feature of reality. There was never a wall to break down, because no wall ever existed.

Relevance to Erwin Schrodinger

Schrödinger developed wave mechanics, where quantum systems exist as superpositions until measured — making the observer inseparable from what's observed. His famous cat paradox dramatized this collapse of objectivity. He was deeply influenced by Vedantic philosophy, particularly the Upanishads' teaching that individual consciousness and universal reality are one. His book 'What is Life?' extended this into biology. This quote mirrors both his quantum physics insights and his lifelong conviction that mind and world cannot be cleanly separated.

The era

The 1920s–1940s saw quantum mechanics overturn classical physics' assumption of an observer-independent reality. The Copenhagen interpretation placed measurement — and therefore the observer — at the center of determining physical outcomes. Simultaneously, Western intellectuals were engaging Eastern philosophy seriously. Amid two World Wars, the old Cartesian split between mind and matter felt increasingly untenable. Physics itself seemed to confirm what mystics had long claimed: subject and object were never truly distinct categories to begin with.
