If a man never contradicts himself, the reason must be that he virtually never says anything at all.

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
Anyone who never contradicts themselves is probably saying nothing substantive. Real intellectual engagement requires taking positions that can later conflict with new evidence or deeper thinking. Contradiction is the natural byproduct of genuinely wrestling with complex ideas over time — a thinker who always stays consistent is likely just repeating safe, empty platitudes rather than actually exploring truth.
Relevance to Erwin Schrodinger
Schrödinger spent his career upending settled science — his wave equation contradicted classical mechanics, and his famous cat paradox deliberately contradicted intuitive reality to expose quantum measurement problems. He frequently revised his own positions across physics, biology, and philosophy. A man who argued against his own Copenhagen contemporaries would naturally see self-contradiction as intellectual honesty rather than weakness.
The era
The early-to-mid 20th century saw quantum mechanics demolish centuries of Newtonian certainty, forcing physicists to contradict their own prior convictions repeatedly. Einstein, Bohr, Heisenberg, and Schrödinger publicly disagreed — and contradicted themselves — as the field evolved. In this environment of radical scientific upheaval, intellectual flexibility and willingness to reverse positions wasn't shameful; it was scientifically necessary.
