Can't you be bothered to look them up yourself or at least ask people if they have ever seen a citation for a particular potential quotation?
Here is what you do: start with the obvious book by A. Pais, find the citations you need if they are there, and post these citations (if you can find them) so that everyone knows that you are not posting misinformation. Then simply continue this process until you have found and revealed citations for all the supposed quotations that you have conjured out of nowhere and decided to post anyway.
Also, your OP ought to be self-deleted unless you can defend it: i.e., I would love see your citation for that god-awful piece of text and the original German from which it supposedly emanates - if you can be bothered to find it. Can you even begin to try to defend that quotation as anything other that balderdash? As it stands, it is your claim and, therefore, your burden of proof. Give me a valid citation to an original source, and I'll retract this paragraph.
If you cannot do the above, just post the quotation to a pseudo-science/fantasy group as a conjecture and ask others if they have ever seen a citation for the quotation.
Peace.
