Science Is Organized Knowledge

Immanuel Kant? Herbert Spencer? Thomas Henry Huxley? R. Strachey?

tree10Dear Quote Investigator: The following two part adage is usually attributed to the famous 18th century German philosopher Immanuel Kant:

Science is organized knowledge. Wisdom is organized life.

I have not seen any citation in German or English showing that Kant ever wrote or said this. Would you please explore this saying?

Quote Investigator: This entry examines only the first sentence of this two sentence quotation, and a separate entry explores the full quotation.

Immanuel Kant died in 1804, and the earliest evidence found by QI appeared many years later. In May 1854 the prominent English philosopher and sociologist Herbert Spencer published an essay titled “The Art of Education” in “The North British Review” which included the adage. Boldface has been added to excerpts. 1

A leading phenomenon in human progress is, that every science is evolved out of its corresponding art. It results from the necessity we are under, both individually and as a race, of reaching the abstract by way of the concrete, that there must be practice and an accruing experience with its empirical generalizations, before there can be science. Science is organized knowledge; and before knowledge can be organized, some of it must first be possessed. Every study, therefore, should have a purely experimental introduction; and only after an ample fund of observations has been accumulated, should reasoning begin.

QI believes that Spencer should be credited with this definitional phrase. The statement has been ascribed to him in multiple reference works, e.g., “A New Dictionary of Quotations” compiled by H. L. Mencken 2 and the “FPA Book of Quotations” selected by Franklin Pierce Adams. 3
