I ran in to a great excerpt from a letter Thomas Jefferson wrote to Isaac McPherson in 1813 about the nature of ideas. It’s not the first time I’ve run across it, and like my Ben Franklin quote it has seen a lot of use in patent discussions, but it’s the kind of thing I think needs to be found on movingtofreedom.org. Looking at more of the letter:
It has been pretended by some, (and in England especially,) that inventors have a natural and exclusive right to their inventions, and not merely for their own lives, but inheritable to their heirs. But while it is a moot question whether the origin of any kind of property is derived from nature at all, it would be singular to admit a natural and even an hereditary right to inventors. It is agreed by those who have seriously considered the subject, that no individual has, of natural right, a separate property in an acre of land, for instance.
By an universal law, indeed, whatever, whether fixed or movable, belongs to all men equally and in common, is the property for the moment of him who occupies it, but when he relinquishes the occupation, the property goes with it. Stable ownership is the gift of social law, and is given late in the progress of society. It would be curious then, if an idea, the fugitive fermentation of an individual brain, could, of natural right, be claimed in exclusive and stable property.
That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property.
Society may give an exclusive right to the profits arising from them, as an encouragement to men to pursue ideas which may produce utility, but this may or may not be done, according to the will and convenience of the society, without claim or complaint from anybody. Accordingly, it is a fact, as far as I am informed, that England was, until we copied her, the only country on earth which ever, by a general law, gave a legal right to the exclusive use of an idea. In some other countries it is sometimes done, in a great case, and by a special and personal act, but, generally speaking, other nations have thought that these monopolies produce more embarrassment than advantage to society; and it may be observed that the nations which refuse monopolies of invention, are as fruitful as England in new and useful devices.
–Thomas Jefferson, letter to Isaac McPherson, 13 August 1813
That uchicago.edu web page has a copyright notice, but surely this must be in the public domain by now, right? (This is one of the things that bugs me about copyrights–people claim them for everything.) It was all one chunk of text, so I took the liberty of inserting paragraph breaks.
Practical. Do patents encourage or stifle innovation? Do “monopolies produce more embarrassment than advantage to society”? Are they necessary or will people invent anyway? I think they will invent anyway.
Inspiring. “He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.”
That’s the right stuff.
