"When I was young, I thought I was the best formalist of my time. I thought I was a revolutionary. When the big problems would come, I would be the one to solve them. But then the great revolution came, it was Heisenberg and Dirac who made it. I was only a classicist."

— from Self-reflection

"The layman always means, when he says 'reality,' that he is speaking of something self-evidently known; whereas to me it seems the most important and exceedingly difficult task of our time is to work on the construction of a new idea of reality."

— from Letter to Markus Fierz, 1954

"A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."

— from Attributed to Max Planck, but often quoted by Pauli in discussions of scientific change

All quotes by Wolfgang Pauli (673)

The unity of knowledge requires a bridge between the natural sciences and the humanities.

Correspondence

The search for symmetry principles is the most profound activity in theoretical physics.

Writings

I cannot believe God plays dice with the universe—but it seems He does.

Paraphrase of Einstein with agreement

The history of physics is a history of increasingly precise concepts and increasingly abstract mathematics.

Essay

The positivist only sees what is measurable, but the most important things are often not measurable.

Critique of positivism

The Copenhagen interpretation is not a philosophy, it is a warning not to philosophize beyond what the formalism allows.

On quantum mechanics

The 'inner' and the 'outer' world are complementary aspects of one reality.

Influence of Jung

The goal of science is not to open a door to infinite wisdom, but to set a limit to infinite error.

Attributed

A theory that is not refutable by any conceivable event is non-scientific.

On scientific method

The discovery of the exclusion principle was for me a matter of pure logic, not of physical intuition.

Nobel Lecture 1946

The mathematical framework of quantum mechanics is complete; the interpretation is the philosophical problem.

Debate

The so-called 'Pauli Effect' is merely the manifestation of my unconscious opposition to imperfect apparatus.

Joking remark

We must remember that what we observe is not nature itself, but nature exposed to our method of questioning.
