Huxley was certainly a more, ahh, 'sober' exponent of the utility of LSD. I am particularly impressed that on his deathbed, unable to speak, he made a written request to his wife for LSD, 100 micrograms, i.m. and died peacefully the following morning. Obviously he knew what he was doing.

In contrast Leary was a irreverant counter-cultural icon. Despite the successes he had with reforming alcoholics and criminals through LSD therapy, I think he really upset the man when he escaped from prison and tried to potray the act as an artistic prank. No wonder when he was caught the US government posted 5 billion dollars bail.
