I know Luka doesn't like quote dumps but the first thing i thought of when i saw this thread was this from Macbeth:
Ay, in the catalogue ye go for men,
As hounds and greyhounds, mongrels, spaniels, curs,
Shoughs, water-rugs, and demi-wolves are clept
All by the name of dogs. The valued file
Distinguishes the swift, the slow, the subtle,
The housekeeper, the hunter, every one
According to the gift which bounteous nature
Hath in him closed, whereby he does receive
Particular addition, from the bill
That writes them all alike. And so of men.
Now, if you have a station in the file,
Not i' th' worst rank of manhood, say ’t.
