Adrian Tchaikovsky said this quote

In Collegium it had been the fashion, while he had been resident there, to paint death as a grey-skinned, balding Beetle man in plain robes, perhaps with a doctor's bag but more often an artificer's toolstrip and apron, like the man who came in, at the close of the day, to put out the lamps and still the workings of the machines.Among his own people, death was a swift insect, gleaming black, its wings a blur - too fast to be outrun and too agile to be avoided, the unplumbed void in which he swam was but the depth of a single facet of its darkly jewelled eyes.

Ah, but it is an interesting thing, that these things can so seldom be proved. If I were to perform some piece of, hrmf, magic for you, here in this room, you would claim a thousand ways it could have been done. Indeed, those ways might be exceedingly unlikely, but you would cling to them rather than accept the, mmn, the chance that magic, the eternal inexplicable, might be the true agent, and if you were strong enough in yourself, unafraid, unthreatened, here in your own chambers, well perhaps there would be no magic worked at all. It is a subjective force, you see, whereas the physical laws of the artificers are objective. A gear-train will turn without faith, but magic may not. And so, when your people demand, mmn, proof, there is none, but when you have forgotten and dismissed it, then magic creeps back into the gaps where you do not look for it.

Progress is made by the improvement of people, not the improvement of machines.

All things die,' she told him. Such a truism, it was the trite utterance of any street-corner philosopher, but coming from Inaspe Raimm it sounded different. 'All things reach the end of their journey, be they trees, insects, people or even principalities. All things die so that others may take their place. To die is no tragedy. The tragedy is dying with a purpose unfulfilled.
