“Why would we do this? she asked, watching smoke trickle towards the ceiling. A whole world of rigid rules covering temperature, convection and Brownian motion all busily pretending to be truly chaotic.”

Letter to Arsacius, High-priest of Galatia (June? 362), as translated by Emily Wilmer Cave Wright, in The Works of the Emperor Julian, Volume III (1913)
General sources
Context: The Hellenic religion does not yet prosper as I desire, and it is the fault of those who profess it; for the worship of the gods is on a splendid and magnificent scale, surpassing every prayer and every hope. May Adrasteia pardon my words, for indeed no one, a little while ago, would have ventured even to pray for a change of such a sort or so complete within so short a time. Why, then, do we think that this is enough, why do we not observe that it is their benevolence to strangers, their care for the graves of the dead and the pretended holiness of their lives that have done most to increase atheism? I believe that we ought really and truly to practise every one of these virtues. And it is not enough for you alone to practise them, but so must all the priests in Galatia, without exception. … In every city establish frequent hostels in order that strangers may profit by our benevolence; I do not mean for our own people only, but for others also who are in need of money. I have but now made a plan by which you may be well provided for this; for I have given directions that 30,000 modii of corn shall be assigned every year for the whole of Galatia, and 60,000 pints of wine. I order that one-fifth of this be used for the poor who serve the priests, and the remainder be distributed by us to strangers and beggars. For it is disgraceful that, when no Jew ever has to beg, and the impious Galilaeans support not only their own poor but ours as well, all men see that our people lack aid from us. Teach those of the Hellenic faith to contribute to public service of this sort, and the Hellenic villages to offer their first fruits to the gods; and accustom those who love the Hellenic religion to these good works by teaching them that this was our practice of old.

Even if we knew every rule, however, we might not be able to understand why a particular move is made in the game, merely because it is too complicated and our minds are limited. If you play chess you must know that it is easy to learn all the rules, and yet it is often very hard to select the best move or to understand why a player moves as he does. So it is in nature, only much more so.

A Theory of Roughness (2004)
Context: When you seek some unspecified and hidden property, you don't want extraneous complexity to interfere. In order to achieve homogeneity, I decided to make the motion end where it had started. The resulting motion biting its own tail created a distinctive new shape I call Brownian cluster. … Today, after the fact, the boundary of Brownian motion might be billed as a "natural" concept. But yesterday this concept had not occurred to anyone. And even if it had been reached by pure thought, how could anyone have proceeded to the dimension 4/3? To bring this topic to life it was necessary for the Antaeus of Mathematics to be compelled to touch his Mother Earth, if only for one fleeting moment.
