Depth Quotes - page 23
We are to remember what an umpire Nature is; what a greatness, composure of depth and tolerance there is in her. You take wheat to cast into the Earth's bosom; your wheat may be mixed with chaff, chopped straw, barn-sweepings, dust and all imaginable rubbish; no matter: you cast it into the kind just Earth; she grows the wheat, - the whole rubbish she silently absorbs, shrouds it in, says nothing of the rubbish. The yellow wheat is growing there; the good Earth is silent about all the rest, - has silently turned all the rest to some benefit too, and makes no complaint about it! So everywhere in Nature! She is true and not a lie; and yet so great, and just, and motherly in her truth. She requires of a thing only that it be genuine of heart; she will protect it if so; will not, if not so. There is a soul of truth in all the things she ever gave harbor to. Alas, is not this the history of all highest Truth that comes or ever came into the world?
Thomas Carlyle
The most important mine of Jesus-Maria at this time was one called Santa Juliana, which had been the means of alternately making and sinking several splendid fortunes. This mine had then reached a depth of between eight and nine hundred feet, and the operations were still tending downwards. The materials were drawn up by mule power applied to a windlass: but as the rope attached to it only extended half way down, another windlass had been erected at the distance of about four hundred feet from the mouth of the cavern, which was also worked by mules, and drew the ores, etc., from the bottom. On one occasion, as I was standing near the aperture of this great pit, watching the ascent of the windlass-rope, expecting every moment the appearance of the large leathern bucket which they employ for drawing up the minerals as well as the rubbish and water from the bottom, what should greet my vision but a mule...

The total subject of mathematics is clearly too broad for any one of us. I do not think that any mathematician since Gauss has covered it fully and uniformly, even Hilbert did not, and all of us are of considerably lesser width (quite apart from the question of depth) than Hilbert. It would therefore, be quite unrealistic not to admit, that any address I could possibly give would not be biased towards some areas in mathematics in which I have had some experience, to the detriment of others which may be equally or more important. To be specific, I could not avoid a bias towards those parts of analysis, logics, and certain border areas of the applications of mathematics to other sciences in which I have worked. If your Committee feels that an address which is affected by such imperfections still fits into the program of the Congress, and if the very generous confidence in my ability to deliver continues, I shall be glad to undertake it.
