Make it a rule never to give a child a book you would not read yourself.

Writing a book is an adventure. To begin with it is a toy and an amusement. Then it becomes a mistress, then it becomes a master, then it becomes a tyrant. The last phase is that just as you are about to be reconciled to your servitude, you kill the monster and fling him to the public.

It was great fun writing a book.... It built an impalpable crystal sphere around one of interests and ideas. In a sense one felt like a goldfish in a bowl; but in this case the goldfish made his own bowl. This came along everywhere with me. It never got knocked about in travelling, and there was never a moment when agreeable occupation was lacking. Either the glass had to be polished, or the structure extended or contracted, or the walls required strengthening.

Don't join the book burners. Don't think you are going to conceal faults by concealing evidence that they ever existed.

Don't be afraid to go in your library and read every book, as long as that document does not offend our own ideas of decency. That should be the only censorship.

Writing a long and substantial book is like having a friend and companion at your side, to whom you can always turn for comfort and amusement, and whose society becomes more attractive as a new and widening field of interest is lighted in the mind.
