Book

"What an astonishing thing a book is.
It’s a flat object, made from a tree with flexible parts, on which are
imprinted lots of funny dark squiggles.
But one glance at it and you are inside the mind of another person
maybe somebody dead for thousands of years.
Across the millennia, an author is speaking clearly and silently
inside your head. Directly to you.
Writing is perhaps the greatest of human inventions.
Binding together people who never knew each other. Citizens of
distant epochs.
Books break the shackles of time.
A book is proof that humans are capable of working magic."

Carl Sagan
