 In respect to lock-making, there can scarcely be such a thing as dishonesty 
 of intention: the inventor produces a lock which he honestly thinks will 
 possess such and such qualities; and he declares his belief to the world.
 If others differ from him in opinion concerning those qualities, it is open
 to them to say so; and the discussion, truthfully conducted, must lead to
 public advantage: the discussion stimulates curiosity, and curiosity stimu-
 lates invention.  Nothing but a partial and limited view of the question
 could lead to the opinion that harm can result: if there be harm, it will be
 much more than counterbalanced by good."
-- Charles Tomlinson's Rudimentary Treatise on the Construction of Locks, 
   published around 1850.
