Carl Sagan said,

"What an astonishing thing a book is. It is 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're inside the mind of another person. [...] 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. Books are proof that humans are capable of working magic."
