Abstract In this article, the author diagnoses the cause of Rand's problematic position on intellectual property. He argues that Rand treats credit as a very thick concept. Rand sees crediting a person with inventing something as granting that person a right to the money embodied in the invention, its sale, and the profits related to licensing reproduction. The author shows that this thick notion of credit leads Rand to make several questionable claims in her arguments for intellectual property rights.
