Intellectual property rights are a cause of disagreement between Lysander Spooner, Stephan Kinsella, and Ayn Rand.
Thats the first sentence of a paper Im grading for my business ethics class. It seems true (grammar aside). But it strikes me that this creates a problem for my anti-IP position.
After all, its an established philosophical principle that nothing nonexistent can cause something real. Yet intellectual property rights are the cause of a real disagreement. Therefore, intellectual property rights must exist. Damn.
Okay, back to grading.
