——《致郑藻如书》（1890年）
The best way to understand contemporary art is to look at lots of it.
The present state of the system of nature is evidently a resultant of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.
我们都是偶然与必然的产物。
