“The distance between one historical period and another is a very small step in comparison to the huge metaphysical gap we must leap to understand the perspective of another person in any time or place.”

“I will persist until I succeed. Always will I take another step. If that is of no avail I will take another, and yet another. In truth, one step at a time is not too difficult... I know that small attempts, repeated, will complete any undertaking.”

“When one historical period is replaced by another, there isalways a group of people left over from the old society”

“Any nation that expects to be ignorant and free," Jefferson said, "expects what never was and never will be." And if the gap between the educated and the uneducated in America continues to grow as it is in our time, as fast as or faster than the gap between the rich and the poor, the gap between the educated and the uneducated is going to be of greater consequence and the more serious threat to our way of life. We must not, by any means, misunderstand that.”

“He and I had already had our time, and though it was still very close and real to me, as beautiful and poignant as any place on a map, it was, in truth, another time—another country.”

“If we increase r [in a logistic map] even more, we will eventually force the system into a period-8 limit cycle, then a period-16 cycle, and so on. The amount that we have to increase r to get another period doubling gets smaller and smaller for each new bifurcation. This cascade of period doublings is reminiscent of the race between Achilles and the tortoise, in that an infinite number of bifurcations (or time steps in the race) can be confined to a local region of finite size. At a very special critical value, the dynamical system will fall into what is essentially an infinite-period limit cycle. This is chaos.”
