Um, this is a discussion board. He is not writing a graduate thesis, and he DID cite the damned book, including the fact that it was a PDF edition. What do you want, a two-page synopsis with parenthetical citations to a known edition that just happens to be the same one you have?
He cited a book, then gave page numbers for his excerpts. This is a much more thorough citation than normally accompanies argument around here, and is easily verifiable, so it's decidedly unlikely that he's lying about owning the work in question.
Nonetheless, you responded that, because you have a different edition and those pages of YOUR EDITION do not say those things, he must be lying? How in Hell is that an acceptable response to his clearly honest effort to provide evidence for his argument? Reported.
Do you watch alot of Fox news? Because you've certainly put a Fox news worthy spin on this.
To simplify it for you
He made an to me outrageous claim.
I asked for his source.
He gave a quote but failed to give the source.
I asked for his source.
He gave a source, but failed to give a page number.
I asked for the page number.
He gave page numbers and
he asked if I thought he was lying.
I failed to find his quotes at the given page numbers, checked if there were any other editions of the book available at online stores (which I couldn't find) and I answered that I thought he was lying.
Then he said he took the quotes from a pdf document of the book.
At that point I realised that the page numbering of his pdf document was off, and began searching the book for his quotes to be able to have a meaningfull discussion, which I did.
I still do not see what I could have done differently as I was not given the correct information before calling him a liar in answer to a direct question.
And you still haven't answered my direct question: He asked for my opinion, what should I have done? Lied to him?
