Not only can you not step into the same river twice; it is not even the same you who can't step into the same river twice. Everything modifies everything. There is no niche in the past waiting for him to come back and occupy it. Nature will tolerate a paradox, but she abhors a vacuum.

The same polarity of the male and female principle exists in nature; not only, as is obvious in animals and plants, but in the polarity of the two fundamental functions, that of receiving and penetrating. It is the polarity of earth and rain, of the river and the ocean, of night and day, of darkness and light, of matter and spirit.
Erich Fromm
There are books so alive that you're always afraid that while you weren't reading, the book has gone and changed, has shifted like a river; while you went on living, it went on living too, and like a river moved on and moved away. No one has stepped twice into the same river. But did anyone ever step twice into the same book?
Marina Tsvetaeva
