Schrodinger's "My View of the World"

This thin volume, published in 1961 contains two never before
published essays. The first, Seek for the Road of 1925 and the other,
What Is Real of 1960 were brought together in My View of the World.


In the latter, the Nobel Prize winner in physics casts doubt on the
existence of a real external world. He says George Berkeley and David
Hume got it right. In
"What Is Real", Schrodinger decries dualism as follows, 'If we decide
to have only one sphere, it has got to be the psychic one, since that
exists anyway (cogitat est).

It seems to me that his view of the world is metaphysical. True he
wrote in 1960 and died soon thereafter, but I wonder if he would be
compelled to revise his thinking in the light of today's mind science?
The mind and the brain are essentially the same thing.

Schrodinger says of his view that an ethic can be derived from it. To
do the same from materialistic determinism would be difficult.
