Of all ghosts the ghosts of our old loves are the worst.

No ghosts need apply.

- Sherlock Holmes: The Adventure of the Sussex Vampire

To the man who loves art for its own sake, it is frequently in its least important and lowliest manifestations that the keenest pleasure is to be derived.

We can't command our love, but we can our actions.

Our ideas must be as broad as Nature if they are to interpret Nature.

It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.
