It's fun to put history in context. A good piece on phlogiston theory.

One quote:

The Phlogistians were not a bunch of cranks. They were serious scientists who helped resolve some of the basic questions of chemistry, by being the devil's advocate against the Antiphlogistians, and by discovering important experiments. And, for almost the entire 18th century, the phlogiston theory was more satisfying than the alternative, in some ways. The Antiphlogistians deduced that combustion was when a substance combined with oxygen (Priestley's dephlogisticated air). But, they could not tell why substances combined with oxygen, or even why all substances didn't just burn up. Phlogiston theory explained why, because some substances were rich in phlogiston, and burned. It was only later that more satisfactory explanations were discovered.
