“Those of other Poets have a constant resemblance, which shows that they received them from one another, and were but multipliers of the same image; each picture like a mock-rainbow is but the reflection of a reflection. 

But every single character in Shakespeare is as much an Individual, as those in Life itself; it is as impossible to find any two alike; and such as from their relation or affinity in any respect appear not to be Twins, will upon comparison be found remarkably distinct.”

A. Pope
