The Beginning of Infinity by David Deutsch is full of Popper's
methodology. Also one can find there a statement that the knowledge
exists objectively.
On the other hand, Maarten Hoenen in his lectures several times has
mentioned Popper's World 3. Interestingly enough that though Deutsch
seems to like Popper a lot, in his book he has mentioned nothing about
this part of Popper's heritage.
Hence I have finally decided to learn what Popper's World 3 is. It
happened that Popper had a very special view on where the objective
knowledge exist. A couple of quotes are below. They could be useful in a
discussion with a Popperian. Popper seems to be not a dualist but rather
a trialist.
Three Worlds, Karl Popper
The Tanner Lecture On Human Values
Delivered at The University of Michigan, April 7, 1978
“In this lecture I intend to challenge those who uphold a monist or even
a dualist view of the universe; and I will propose, instead, a pluralist
view. I will propose a view of the universe that recognizes at least
three different but interacting sub-universes.”
“To sum up, we arrive at the following picture of the universe. There
is the physical universe, world 1, with its most important sub-universe,
that of the living organisms. World 2, the world of conscious
experience, emerges as an evolutionary product from the world of
organisms. World 3, the world of the products of the human mind,
emerges as an evolutionary product from world 2.”
“If I am right that the physical world has been changed by the world 3
products of the human mind, acting through the intervention of the human
mind then this means that the worlds 1, 2, and 3, can interact and,
therefore, that none of them is causally closed. The thesis that the
physical world is not causally closed but that it can be acted upon by
world 2 and, through its intervention, by world 3, seems to be
particularly hard to swallow for the materialist monist, or the
physicalist.”
“Of course, the materialist will explain it all in terms of our brain
processes; and admittedly, they do play a role in mediating the
intervention of effects from world 3 through world 2 to world 1. But
where the great change originated is in world 3, in our theories. These
have, metaphorically speaking, a kind of life of their own, though they
depend heavily on our minds and, very likely, also on our brains.”
“The feedback effect between world 3 and world 2 is of particular
importance. Our minds are the creators of world 3; but world 3 in its
turn not only informs our minds, but largely creates them. The very idea
of a self depends on world 3 theories, especially upon a theory of time
which underlies the identity of the self, the self of yesterday, of
today, and of tomorrow. The learning of a language, which is a world 3
object, is itself partly a creative act and partly a feedback effect;
and the full consciousness of self is anchored in our human language.”
