200 years Organon of Medicine - A comparative Review of its six editions (1810-1842)

In 2010 the 200th anniversary of the Organon is celebrated by the
homeopathic community. Samuel Hahnemann’s Organon of Rational
Therapeutics, published in 1810, however, marks neither the
beginning of homeopathy nor the endpoint of its development. On the
one hand, its contents are based on terms and concepts developed
and published by Hahnemann during the preceding two decades. On the
other hand, the five revised editions of the Organon that followed
in the next three decades contain major changes of theory and
conceptions. Hahnemann’s basic idea, running through all the stages
of the foundation, elaboration, and defence of his doctrine, may be
detected by a comparative review of his works from a historical and
philosophical perspective.
