The Seven Lamps of Architecture, John Ruskin.

Sacrifice – dedication of man's craft to God, as visible proofs of man's love and obedience.

Truth – handcrafted and honest display of materials and structure. Truth to materials and honest display of construction were bywords since the serious Gothic Revival had distanced itself from the whimsical "Gothick" of the 18th century; it had been often elaborated by Pugin and others.

Power – buildings should be thought of in terms of their massing and reach towards the sublimity of nature by the action of the human mind upon them and the organization of physical effort in constructing buildings.

Beauty – aspiration towards God expressed in ornamentation drawn from nature, his creation

Life – buildings should be made by human hands, so that the joy of masons and stonecarvers is associated with the expressive freedom given them

Memory – buildings should respect the culture from which they have developed

Obedience – no originality for its own sake, but conforming to the finest among existing English values, in particular expressed through the "English Early Decorated" Gothic as the safest choice of style.
