Johann Wolfgang von Goethe 
Goethe’s Theory of Colours 

By the time Goethe’s "Theory of Colours" appeared in 1810, the wavelength theory of light and colour had been firmly established. To Goethe, the theory was the result of mistaking an incidental result for an elemental principle. Far from pretending to a knowledge of physics, he insisted that such knowledge was an actual hindrance to understanding. He based his conclusions exclusively upon exhaustive personal observation of the phenomena of colour. Of his own theory, Goethe was supremely confident: "From the philosopher, we believe we merit thanks for having traced the phenomena of colours to their first sources, to the circumstances under which they appear and are, and beyond which no further explanation respecting them is possible." Goethe’s scientific conclusions have, of course, long since been thoroughly demolished, but the intelligent reader of today may enjoy this work on quite different grounds: for the beauty and sweep of his conjectures regarding the connection between colour and philosophical ideas; for an insight into early nineteenth-century beliefs and modes of thought; and for the flavour of life in Europe just after the American and French Revolutions.
