“Knowledge is limited. Imagination encircles the world.”

Cosmic Religion : With Other Opinions and Aphorisms (1931) by Albert Einstein, p. 97; also in Transformation : Arts, Communication, Environment (1950) by Harry Holtzman, p. 138. This may be an edited version of some nearly identical quotes from the 1929 Viereck interview below.
1930s
Context: I believe in intuition and inspiration. … At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

&quot;Quotes&quot;, The Educated Imagination (1963), Talk 1: The Motive For Metaphor http://northropfrye-theeducatedimagination.blogspot.ca/2009/08/1-motive-for-metaphor.html <br class="br">Context: At the level of ordinary consciousness the individual man is the centre of everything, surrounded on all sides by what he isn&#x27;t. At the level of practical sense, or civilization, there&#x27;s a human circumference, a little cultivated world with a human shape, fenced off from the jungle and inside the sea and the sky. But in the imagination anything goes that can be imagined, and the limit of the imagination is a totally human world.

Nobel Prize Lecture (1993)
Context: Tongue-suicide is not only the choice of children. It is common among the infantile heads of state and power merchants whose evacuated language leaves them with no access to what is left of their human instincts for they speak only to those who obey, or in order to force obedience. The systematic looting of language can be recognized by the tendency of its users to forgo its nuanced, complex, mid-wifery properties for menace and subjugation. Oppressive language does more than represent violence; it is violence; does more than represent the limits of knowledge; it limits knowledge. Whether it is obscuring state language or the faux-language of mindless media; whether it is the proud but calcified language of the academy or the commodity driven language of science; whether it is the malign language of law-without-ethics, or language designed for the estrangement of minorities, hiding its racist plunder in its literary cheek — it must be rejected, altered and exposed. It is the language that drinks blood, laps vulnerabilities, tucks its fascist boots under crinolines of respectability and patriotism as it moves relentlessly toward the bottom line and the bottomed-out mind. Sexist language, racist language, theistic language — all are typical of the policing languages of mastery, and cannot, do not permit new knowledge or encourage the mutual exchange of ideas.
