I wonder if artist James Sanborn has spoofed the CIA by getting them to put a statue on their property which actually refers to their experiments with LSD as a "Philosopher's Stone" that could divine truth.

Here's a paragraph from an article I found on the subject at
http://www.totse.com/en/politics/central_intelligence_agency/ciacid.html

"The whole concept of a truth drug was a bit farfetched to begin with. It presupposed that there was a way to chemically bypass the mind's censor and turn the psyche inside out, unleashing a profusion of buried secrets, and that surely some approximation of "truth" would emerge amidst all the personal debris. In this respect the CIA's quest resembled a skewed version of a familiar mythological theme from which such images as the Philosopher's Stone and the Fountain of Youth derive -- that through touching or ingesting something one can acquire wisdom, immortality, or eternal peace. It is more than a bit ironic that the biblical inscription on the marble wall of the main lobby at CIA headquarters in Langley, Virginia, reads, "And ye shall know the Truth and the Truth shall set you free".
