The idea of this 'House of Vision' was still growing in his mind when he died. He had not yet settled upon a name for it, though he had tried over a number of names--a House of Vision, which is the name we have taken for it here, the Home of Silence, the Hall of Industry, the Anthropaeum, the Making of Man, the Life Creative, the Soul of the School. All these names converge upon the end he was seeking. This approach by trial, by leaving the idea to shape itself for a time and then taking it up again, by talking it over with this man and that, was very characteristic of his mental processes. A member of the staff recalls a stage in the development of the idea. 'I talked with the headmaster about the Yarrow Memorial in October 1920,' he says. 'He then seemed to dally with a suggestion to name it the "Temple of the World"--he expressed his hatred of the tendency to call it the "Museum." I gathered that his idea was to fill it with charts of all things and all ages, including pictures of at least all the world's great men--then to turn a boy loose in it, thereby to realise his position in the world as a unit of its time, as opposed to the inculcation of any idea of his having a part in his nationality only. His root idea seemed to be that it should be a place for meditation--restful as well as invigorating.' Here is a passage written by Sanderson himself a little later. The idea ripens and broadens out very manifestly. 'Every school, every locality and industry,' he writes, 'might build within their boundaries a new kind of chapel, a heritage, a temple--a beautiful building in which are gathered together and exhibited the records of man's great deeds and of man's progress, and the records of his needs. It is such a "Hall of Needs" that we regard the Yarrow Memorial, and to this end it is being equipped.' And here Sanderson speaks again in a sermon preached upon the text of Moses' withdrawal to the mount. 'A school will grow into a book. It will take upon itself the form of a Bible. Within it will appear the stages in the life of the soul--"the coming of a kingdom"; the foundations, the building, the furniture, the complex apparatus, the organised beauty. A school--its buildings, workshops, class-rooms, and all that goes towards a great school--can take on the form of a parable. As we wander from one place to another all that speaks of life will manifest itself before us. How life begins, what is needed for its growth; what shall be its standards, its ideals; what the nature of its proof-plate; the craftsman and what he is; the craftsman in languages, in mathematics, in science, in art; the secrets of nature revealing themselves; progress, change, vision.
