Philosophy begins when you don't know where to look for an answer.

The bone won't come to the dog. It's the dog that goes to the bone.

The living always get over the dead. That’s what the dead never realize. If ever the dead did come back, they’d only have been sore that somehow you managed to get over their dying at all.

And tell them all about the books you've read. Better still, buy some more books and read them. That's an order. You can never read too many books.

A man's bookseller should keep his confidence, like his physician. What can become of a world where every man knows what another man reads? Why, sir, books would become like quacks' potions, with every mountebank in the newspapers claiming one volume's superiority over another.

When you get a cat to catch the mice in your kitchen, you can't expect it to ignore the rats in the cellar.

Sometimes human nature can leave you looking just a little shamefaced.
