A group of new ideas in literature, religion, culture, and philosophy that advocates that there is an ideal spiritual state that 'transcends' the physical and empirical and is only realised through a knowledgeable intuitive awareness that is conditional upon the individual. The concept emerged in New England in the early-to mid-19th century. It is sometimes called "American Transcendentalism" to distinguish it from other uses of the word transcendental. It began as a protest against the general state of culture and society at the time, and in particular, the state of intellectualism at Harvard and the doctrine of the Unitarian church that was taught at Harvard Divinity School. The term transcendentalism sometimes serves as shorthand for "transcendental idealism". Another alternative meaning for transcendentalism is the classical philosophy that God transcends the manifest world. As John Scotus Erigena put it to Frankish king Charles the Bald in the year 840 A.D., "We do not know what God is. God himself doesn't know what He is because He is not anything. Literally God is not, because He transcends being."
