Dat maakt me woedend, hoewel ik toch allang weet dat het in de orde der dingen ligt dat de bevoorrechten de niet-bevoorrechten onderdrukken: op die m… - Primo Levi

Sandro was surprised when I tried to explain to him some of the ideas that at the time I was confusedly cultivating. That the nobility of man, acquired in a hundred centuries of trial and error, lay in making himself the conquerer of matter, and that I had enrolled in chemistry because I wanted to remain faithful to this nobility. That conquering matter is to understand it, and understanding matter is necessary to understanding the universe and ourselves: and that therefore Mendeleev's Periodic Table, which just during those weeks we were laboriously learning to unravel, was poetry, loftier and more solemn than all the poetry we had swallowed down in liceo; and come to think of it, it even rhymed!

...better not to do than to do, better to meditate than to act, better his astrophysics, the threshold of the Unknowable, than my chemistry, a mess compounded of stenches, explosions and small futile mysteries. I thought of another moral, more down to earth and concrete, and I believe that every militant chemist can confirm it: that one must distrust the almost-the-same (sodium is almost the same as potassium, but with sodium nothing would have happened_, the practically identical, the approximate, the or-even, all surrogates, and all patchwork. the difference can be small, but they can lead to radically different consequences, like a railroad's switch points; the chemist's trade consists in good part in being aware of these differences, knowing them close up, and foreseeing their effects. And not only the chemist's trade.

The Gedalists were nearly run down by a Dodge truck on which two grand pianos had been loaded: two uniformed officers were playing, in unison, with gravity and commitment, the 1812 Overture of Tchaikowsky, while the driver wove among the wagons with brusque swerves, pressing the siren at full volume, heedless of the pedestrians in his way.
