The human organism is a highly ordered and organized system, which maintains its order by continually drawing order from its environment.

More from Erwin Schrodinger
"Quantum mechanics has taught us that the world is not as solid and substantial as we thought."
"The quantum theory is an 'unpleasant' theory, which I should have liked to assume to be true only if I were forced to do so by the facts."
"The world is a construct of our sensations, perceptions, memories. It is convenient to regard it as existing objectively. But it is not a logical necessity."
"Our [Western] science has cut itself off from an adequate understanding of the Subject of Cognizance, of the mind."
"What is life? The physicist's answer to this question is a series of surprises."
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
Living organisms are ordered structures that resist the natural tendency toward disorder (entropy). They maintain their internal organization by continuously pulling order from their surroundings—through food, sunlight, and nutrients. Unlike inert matter, which drifts toward chaos, life actively harvests structure from the environment to sustain and replicate itself. This is fundamentally what metabolism accomplishes: importing order to offset the organism's own internal decay.
Relevance to Erwin Schrodinger
Schrödinger derived the wave equation foundational to quantum mechanics, but his 1944 book 'What is Life?' extended physics into biology. He coined 'negentropy'—the idea that organisms survive by consuming negative entropy from their environment. This quote distills that thesis. His conviction that physics could fully explain biological self-organization defined his later career and directly inspired Watson and Crick's pursuit of DNA's molecular structure.
The era
Written in 1944 amid WWII, as thermodynamics was being extended into new domains and Shannon's information theory was taking shape. Scientists were urgently asking what physically separated life from non-life. This quote marks the moment physicists formally entered biology, launching a conceptual revolution that culminated in the 1953 discovery of DNA and the founding of molecular biology as a discipline.
