Laboratory Alchemy and Spiritual Alchemy Compared

Furnace or soul? How the Victorians reread the alchemists.

For most of its history alchemy was a practical art: distillation, metals, medicines, with a religious and philosophical frame. In the nineteenth century writers such as Mary Anne Atwood argued it had always been a secret science of the soul. Jung later gave that reading a psychological form.

What It Is

The historical alchemists worked with real substances and furnaces, even when their language was allegorical. The spiritual reading treats the stages of the work as stages of inner transformation. The truth is often mixed: many alchemists saw no line between the two.

Why It Matters

Historians of science now take practical alchemy seriously as a forerunner of chemistry. Reading both kinds of text keeps you from assuming every alchemical book is either pure chemistry or pure mysticism.
