The universe is change; our life is what our thoughts make it.

We only have to look around us to see how complexity and psychic temperature are still rising: and rising no longer on the scale of the individual but now on that of the planet. This indication is so familiar to us that we cannot but recognize the objective, experiential, reality of a transformation of the planet as a whole.

Change begets change. Nothing propagates so fast.

Motion or change, and identity or rest, are the first and second secrets of nature: Motion and Rest. The whole code of her laws may be written on the thumbnail, or the signet of a ring.

Nothing endures but change.

You could not step twice into the same river; for other waters are ever flowing on to you.

Change is not made without inconvenience, even from worse to better.

Change is not merely necessary to life — it is life.

Se vogliamo che tutto rimanga come è, bisogna che tutto cambi.

Let us go to war. The world has become stale and insipid, the ships ought to be all captured, and the cities battered down, and the world burned up, so that we can start again. There would be fun in that. Some interest, — something to talk about.
