It is amusing, if anything connected with this stupid catastrophe can be amusing, to see the secretly crestfallen attitude of technicians. They are the high priests of the modern cult of perfected material and of mechanical appliances, and would fain forbid the profane from inquiring into its mysteries. We are the masters of progress, they say, and you should remain respectfully silent. And they take refuge behind their mathematics. I have the greatest regard for mathematics as an exercise of mind. It is the only manner of thinking which approaches the Divine. But mere calculations, of which these men make so much, when unassisted by imagination and when they have gained mastery over common sense, are the most deceptive exercises of intellect. Two and two are four, and two are six. That is immutable; you may trust your soul to that; but you must be certain first of your quantities. I know how the strength of materials can be calculated away, and also the evidence of one's senses. For it is by some sort of calculation involving weights and levels that the technicians responsible for the _Titanic_ persuaded themselves that a ship _not divided_ by water-tight compartments could be "unsinkable." Because, you know, she was not divided. You and I, and our little boys, when we want to divide, say, a box, take care to procure a piece of wood which will reach from the bottom to the lid. We know that if it does not reach all the way up, the box will not be divided into two compartments. It will be only partly divided. The _Titanic_ was only partly divided. She was just sufficiently divided to drown some poor devils like rats in a trap. It is probable that they would have perished in any case, but it is a particularly horrible fate to die boxed up like this. Yes, she was sufficiently divided for that, but not sufficiently divided to prevent the water flowing over. Therefore to a plain man who knows something of mathematics but is not bemused by calculations, she was, from the point of view of "unsinkability," not divided at all. What would you say of people who would boast of a fireproof building, an hotel, for instance, saying, "Oh, we have it divided by fireproof bulkheads which would localise any outbreak," and if you were to discover on closer inspection that these bulkheads closed no more than two-thirds of the openings they were meant to close, leaving above an open space through which draught, smoke, and fire could rush from one end of the building to the other? And, furthermore, that those partitions, being too high to climb over, the people confined in each menaced compartment had to stay there and become asphyxiated or roasted, because no exits to the outside, say to the roof, had been provided! What would you think of the intelligence or candour of these advertising people? What would you think of them? And yet, apart from the obvious difference in the action of fire and water, the cases are essentially the same.
