By the time Goethe's "Theory of Colours" appeared in 1810, the wavelength theory of light and color 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 color.
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 color and philosophical ideas; for an insight into early nineteenth-century beliefs and modes of thought; and for the flavor of life in Europe just after the American and French Revolutions.
The work may also be read as an accurate guide to the study of color phenomena. Goethe's conclusions have been repudiated, but no one quarrels with his reporting of the facts to be observed. With simple objects -- vessels, prisms, lenses, and the like -- the reader will be led through a demonstration course not only in subjectively produced colors, but also in the observable physical phenomena of color. By closely following Goethe's explanations of the color phenomena, the reader may become so divorced from the wavelength theory -- Goethe never even mentions it -- that he may begin to think about color theory relatively unhampered by prejudice, ancient or modern.
A master of poetry, drama, and the novel, German writer and scientist Johann Wolfgang von Goethe spent 50 years on his two-part dramatic poem Faust, published in 1808 and 1832, also conducted scientific research in various fields, notably botany, and held several governmental positions.
George Eliot called him "Germany's greatest man of letters... and the last true polymath to walk the earth." Works span the fields of literature, theology, and humanism. People laud this magnum opus as one of the peaks of world literature. Other well-known literary works include his numerous poems, the Bildungsroman Wilhelm Meister's Apprenticeship and the epistolary novel The Sorrows of Young Werther.
With this key figure of German literature, the movement of Weimar classicism in the late 18th and early 19th centuries coincided with Enlightenment, sentimentality (Empfindsamkeit), Sturm und Drang, and Romanticism. The author of the scientific text Theory of Colours, he influenced Darwin with his focus on plant morphology. He also long served as the privy councilor ("Geheimrat") of the duchy of Weimar.
Goethe took great interest in the literatures of England, France, Italy, classical Greece, Persia, and Arabia and originated the concept of Weltliteratur ("world literature"). Despite his major, virtually immeasurable influence on German philosophy especially on the generation of Georg Wilhelm Friedrich Hegel and Friedrich Wilhelm Joseph von Schelling, he expressly and decidedly refrained from practicing philosophy in the rarefied sense.
Influence spread across Europe, and for the next century, his works inspired much music, drama, poetry and philosophy. Many persons consider Goethe the most important writer in the German language and one of the most important thinkers in western culture as well. Early in his career, however, he wondered about painting, perhaps his true vocation; late in his life, he expressed the expectation that people ultimately would remember his work in optics.
