While the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty. You can, for example, never foretell what any one man will be up to, but you can say with precision what an average number will be up to. Individuals vary, but percentages remain constant. So says the statistician.

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

I slipped through his grip, and he with a horrible scream kicked madly for a few seconds and clawed the air with both his hands.

Far away on the path we saw Sir Henry looking back, his face white in the moonlight, his hands raised in horror, glaring helplessly at the frightful thing which was hunting him down. But that cry of pain from the hound had blown all our fears to the winds. If he was vulnerable he was mortal, and if we could wound him we could kill him.

Let me run over the principal steps. We approached the case, you remember, with an absolutely blank mind, which is always an advantage. We had formed no theories. We were simply there to observe and to draw inferences from our observations.
-
Some facts should be suppressed, or, at least, a just sense of proportion should be observed in treating them.
-
There is nothing like first-hand evidence.
-
The fair sex is your department.
-
We balance probabilities and choose the most likely. It is the scientific use of the imagination.
-
Streams may spring from one source, and yet some be clear and some be foul.
-
Come what may, I am bound to think that all things are ordered for the best; though when the good is a furlong off, and we with our beetle eyes can only see three inches, it takes some confidence in general principles to pull us through.

Yet birth, and lust, and illness, and death are changeless things, and when one of these harsh facts springs out upon a man at some sudden turn of the path of life, it dashes off for the moment his mask of civilization and gives a glimpse of the stranger and stronger face below.
