… Einstein as a Jew and a Philosopher by Freeman Dyson | The New York Review of Books. (Hat tip, Dave Lull.)

The dualistic philosophy gives a natural frame for the new sciences of particle physics and relativistic cosmology that emerged in the twentieth century after Einstein and Bohr were dead. The new sciences are dominated by mathematical symmetries that are exact in the second layer and approximate in the first layer. The dualistic philosophy seems to me to represent accurately our present state of knowledge. It says that the classical world and the quantum world are both real, but the way they fit together is not yet completely understood. The dualistic philosophy is flexible enough to accept unexpected discoveries and conceptual revolutions.
