Diogenes tried hard to challenge the ideas underpinning alchemy. He was a troll, attending lectures and making fun of what was said or otherwise distracting from the solemnity of the moment. He wore only a blanket, slept where he wanted, tried his best to live a completely honest life, though not a comfortable one. He tried to live up to his own high ideals.

You can search out and read the many stories of the life of Diogenes, but his manner platform.

Diogenes couldn't do it. But he was our first cynic. Today cynicism is one of the foundations of the scientific method: don't believe anything which isn't multiple-times proven.
