Work of fiction? Yes *applause*
Apocryphal? No.
Connected with politics? *amused laughter from audience* Some would say yes. Others (perhaps more?) would say no. One reasonable answer is "I don't know". Another is "if you like".
One word answer? No.

[IS,P!] At least as a working definition I take 'human construct' to mean something that requires the human brain for its existence. Most abstract things seem to be human constructs, but not all are. I would say that 'pain', for example, is not a human construct. There are thorny issues when we get into the old debate about whether mathematical issues are created or discovered. Is the following a human construct: on a Euclidean plane, any right-angled triangle has the property that the square on the hypotenuse equals the sum of the squares on the other two sides? I'm not sure.
