Abstract
We intend to analyze the plausibility of the two kind of ethical justifications that are most commonly used in order to defend the concept of an “intellectual property” of copyrights. Firstly, we will examine justifications of property based on natural law, like the one originally provided by John Locke. We will argue, with the help of authors like Lysander Spooner, that the same arguments that Locke uses for property in general are entirely applicable to intellectual property, although this is certainly a peculiar kind of property. Secondly, we will examine whether or not we can apply to intellectual property the same two arguments that Utilitarian authors use for justifying property in general: the “tragedy of the commons” argument and the scarcity argument. We will claim that the first one is fully pertinent here, and that the second one is not: but this is a problem of that kind of justification of property in general, and not a problem of intellectual property as such.
