interesting, you close the chapter and you jump to another part of the
world and we must jump with you whether we like it or not."

I know. It does not seem the right thing to do.

Unfortunately, history is not at all like mathematics.

When you solve a sum you go from "a" to "b" and from "b" to "c" and from
"c" to "d" and so on.

History on the other hand jumps from "a" to "z" and then back to "f" and
next to "m" without any apparent respect for neatness and order.

There is a good reason for this.

History is not exactly a science.

It tells the story of the human race and most people, however much we
may try to change their nature, refuse to behave with the regularity and
the precision of the tables of multiplication.

No two men ever do precisely the same thing.

No two human brains ever reach exactly the same conclusion.

You will notice that for yourself when you grow up.

It was not different a few hundred centuries ago.

Prehistoric man, as I just told you, was on a fair way to progress.
