I wrote Sophies World in three months, but I was only writing and sleeping. I work for 14 hours a day when Im working on a book.

We can be hindered in our development and our personal growth by political conditions. Outer circumstances can constrain us. Only when we are free to develop our innate abilities can we live as free beings. But we are just as much determined by inner potential and outer opportunities as the Stone Age boy on the Rhine, the lion in Africa, or the apple tree in the garden.

Although you may not stumble across a Martian in the garden, you might stumble across yourself. The day that happens, you'll probably also scream a little. And that'll be perfectly all right, because it's not every day you realize you're a living planet dweller on a little island in the universe.

Where did the world come from? The question has an answer, even though I cannot get to it. It is a good question. It is like a crime that has not been solved. There is an answer, even if police do not know it.

If we don't know where we are going, it can be helpful to know where we come from.

Hegel said that `truth` is subjective, thus rejecting the existence of any `truth` above or beyond human reason. All knowledge is human knowledge.
