“Language disguises the thought; so that from the external form of the clothes one cannot infer the form of the thought they clothe, because the external form of the clothes is constructed with quite another object than to let the form of the body be recognized.”
—Ludwig Wittgenstein (1889–1951)
“Nothing is more indispensable to true religiosity than a mediator that links us with divinity.”
—Novalis [Friedrich Von Hardenberg] (1772–1801)
