Organon of Medicine
By Samuel Hahnemann

Hahnemann - (c) HI

The Organon of Medicine is the homeopathic philosophy, the guiding principles of homeopathy enunciated by the great master Dr.Samuel Hahnemann.

The Organon of the Healing Art (Organon der rationellen Heilkunde) by Samuel Hahnemann, 1810, laid the foundations of all theory and method of homeopathy. The work was repeatedly revised by Hahnemann and published in five editions by himself and one posthumously, with the name changed from the second edition onwards to “Organon of Medicine” (Organon der Heilkunst). Hahnemann wrote and published this book (in aphorisms) in order to share his new theory of medicine – “Homeopathy” with public and medical professionals of his time.

An aphorism is an original thought, spoken or written in a laconic (concise) and memorable form. Aphorism literally means a “distinction” or “definition”. The term was first used in the Aphorisms of Hippocrates. The term was later applied to maxims of physical science, then statements of all kinds of philosophical, moral, or literary principles. In modern usage an aphorism is generally understood to be a concise statement containing a subjective truth or observation cleverly and pithily written.

Hahnemann first experienced the effect of Peruvian Bark Cinchona in 1790, and then after six years, in 1796, he published an article under the title “Essay on a New Principle.” And, in 1805 he published an article ‘Medicine of Experience’. After conducting personal observation and experiment, Hahnemann collected his new theory of homeopathy into book form in 1810. The original title of the book was Organon of Rational Art of Healing. In 1819, the second edition was published, with the revised title Organon of Healing Art. The third edition (1824) and fourth edition (1829) kept this new title, while the latter introduced Hahnemann’s “Theory of Chronic Diseases.” The fifth edition was published in 1833, and included the doctrine of vital force and drug-dynamization. The sixth edition, written in 1842, a year before his death, was retitled Organon of Medicine and not published until 1921.

The aphorisms(principles outlined in the Organon) alongwith the commentary on these aphorisms are given here.
