"Hence it is clear that the space of physics is not, in the last analysis, anything given in nature or independent of human thought. It is a function of our conceptual scheme."

Tom shows this quote in one of his youtube videos: Consciousness The Ultimate Reality 2/13.

Does anyone know how did Einstein get to that conclusion?

Thanks!

I am actually not sure if it's a direct quote from Einstein, I found this
"the behaviour or physical bodies as implied in the measurements. Once these assumptions are laid down, the choice of the geometric system is determinded. As Einstein explains, it is the sum total of the assumptions of correlation and of the system of abstract geometry that has to comform to experience. Once the principle that relates rigid bodies to Euclidean solids is accepted, it is experience that conditions the choice of geometry... Hence it is clear that the structure of the space of physics is not, in the last analysis, anything given in nature or independent of human thought. It is a function of our conceptual scheme". In Concepts of Space, Dover Publications. 1993, pp. 172, 173."
from Concepts of Space: The History of Theories of Space in Physics: Third, Enlarged Edition

This paper also attributes it to Jammer on the top of page 4.

Other than that, I do not know enough about Einstein to answer your question.

I don't know but searching around the internet for that quote brings up interesting sites.

I am afraid I can't find that Einstein quote either. At least not from a reliable source. Reliable meaning, that the source is providing some reference to the original quote, the time or the place of the quote of Einstein's speech or any publication bei Einstein. They all seem to just re-use the quote without any reference.

The only reference I could find was here:
http://arxiv.org/pdf/1205.4916.pdf

But in that document, the quote is attributed on page 4 to a guy called Jammer:
As Jammer put it [Jammer, M. (1954)]:
"... Hence it is clear that the structure of the space of physics is not, (...), anything given in nature or independent of human thought. It is a function of our conceptual scheme."

So I am afraid there will be no answer to the question asked by the OP, since it seems to be that Einstein probably never said this exact quote. The other ones about reality being an illusion and space not existing independently are still valid quotes of Einstein though.

This would be the original source for the specific quote above then:
Jammer, M., 1954 - For a brief historical discussion of these works see the book Concepts of Space: the History of Theories of Space in Physics . Cambridge, Mass.: Harvard Univ. Press, Chapter 5

-- edit --

I am sorry, I just realized that Specialis Sapientia beat me to it by more than a year. Sorry for my redundant post. I found the exact same source through googling, but only realized now after diligently reading this thread again, that I could have saved my effort.

Hello Tronar - is this what you are looking for?
http://www.relativitybook.com/resources ... space.html

It includes the following:
Space-time does not claim existence on its own, but only as a structural quality of the field.

Thus Descartes was not so far from the truth when he believed he must exclude the existence of an empty space. The notion indeed appears absurd, as long as physical reality is seen exclusively in ponderable bodies.

It requires the idea of the field as the representative of reality, in combination with the general principle of relativity, to show the true kernel of Descartes' idea; there exists no space "empty of field".
