John Ruskin

After a few years of hearing about John Ruskin as a father of Conservation, I finally sat down and read The Seven Lamps of Architecture. I know it's supposed to be a classic, but the book was pretty bizarre, and made wild claims without any logical supporting arguments. Many of the theories he asserts sound ridiculous, like stating that iron has no place in architecture (Lamp of Truth, IX).
In terms of preservation, we have learned that Ruskin advanced the theory that preservation should take a very inactive role; any intervention in a building necessarily makes the building inauthentic and is thus counterproductive to preservation. The sum of Ruskin's argument can be found in two short sections in Book VI: The Lamp of Memory, sections 19-20. I will quote them in their entirety:


"IXX. Do not let us talk then of restoration. The thing is a Lie from beginning to end. You may make a model of a building as you may of a corpse, and your model may have the shell of the old walls within it as your cast might have the skeleton, with what advantage I neither see nor care; but the old building is destroyed, and that more totally and mercilessly than if it had sunk into a heap of dust, or melted into a mass of clay: more has been gleaned out of desolated Nineveh than ever will be out of re-built Milan. But, it is said, there may come a necessity for restoration! Granted. Look the necessity full in the face, and understand it on its own terms. It is a necessity for destruction. Accept it as such, pull the building down, throw its stones into neglected corners, make ballast of them, or mortar, if you will; but do it honestly, and do not set up a Lie in their place. And look that necessity in the face before it comes, and you may prevent it. The principle of modern times (a principle which I believe, at least in France, to be systematically acted on by the masons, in order to find themselves work, as the abbey of St. Ouen was pulled down by the magistrates of the town by way of giving work to some vagrants,) is to neglect buildings first, and restore them afterwards. Take proper care of your monuments, and you will not need to restore them. A few sheets of lead put in time upon the roof, a few dead leaves and sticks swept in time out of a water-course, will save both roof and walls from ruin. Watch an old building with an anxious care; guard it as best you may, and at any cost from every influence of dilapidation. Count its stones as your would jewels of a crown; set watches about it as if at the gates of a besieged city; bind it together with iron where it loosens; stay it with timber where it declines; do not care about the unsightliness of the aid; better a crutch than a lost limb; and do this tenderly, and reverently, and continually, and many a generation will still be born and pass away beneath its shadow. Its evil day must come at last; but let it come declared and openly, and let no dishonoring and false substitute deprive it of the funeral offices of memory.
"XX. Of more wanton or ignorant ravage it is vain to speak; my words will not reach those who commit them, and yet, be it heard or not, I must not leave the truth unstated, that it is again no question of expediency or feeling whether we shall preserve the buildings of past times or not. We have no right whatever to touch them. They are not ours. They belong partly to those who built them, and partly to all the generations of mankind who are to follow us. The dead have still their right in them: that which they labored for, the praise of achievement or the expression of religious feeling, or whatsoever else it might be which in those buildings they intended to be permanent, we have no right to obliterate. What we have ourselves built, we are at liberty to throw down; but what other men gave their strength, and wealth, and life to accomplish, their right over does not pass away with their death; still less is the right to the use of what they have left vested in us only. It belongs to all their successors. It may hereafter be a subject of sorrow, or a cause of injury, to millions, that we have consulted our present convenience by casting down such buildings as we choose to dispense with. That sorrow, that loss we have no right to inflict. Did the cathedral of Avranches belong to the mob who destroyed it, any more than it did to us, who walk in sorrow to and fro over its foundation? Neither does any building whatever belong to those mobs who do violence to it. For a mob it is, and must be always; it matters not whether enraged, or in deliberate folly; whether countless, or sitting in committees; the people who destroy anything causelessly are a mob, and Architecture is always destroyed causelessly. A fair building is necessarily worth the ground it stands upon, and will be so until central Africa and America shall have become as populous as Middlesex; nor is any cause whatever valid as a ground for its destruction. If ever valid, certainly not now when the place both of the past and future is too much usurped in our minds by the restless and discontented present. The very quietness of nature is gradually withdrawn from us; thousands who once in their necessarily prolonged travel were subjected to an influence, from the silent sky and slumbering fields, more effectual than known or confessed, now bear with them even there the ceaseless fever of their life; and along the iron veins that traverse the frame of our country, beat and flow the fiery pulse of its exertions, hotter and faster every hour. All vitality is concentrated through those throbbing arteries into the central cities; the country is passed over like a green sea by narrow bridges, and we are thrown back in continually closer crowds upon the city gates. The only influence which can in any wise there take the place of that of the woods and fields, is the power of ancient Architecture. Do not part with planted walk, nor of the goodly street nor opened quay. The pride of a city is not in these. Leave them to the crowd; but remember that there will surely be some within the circuit of the disquieted walls who would ask for some other spots that these wherein to walk; for some other forms to meet their sight familiarly: like him who sat so oftern where the sun struck from the west, to watch the lines of the dome of Florence drawn on the deep sky, or like those, his Hosts who could beat daily to behold, from their palace chambers, the places where their fathers lay at rest, at the meeting of the dark streets of Verona."
