Gonzalo Rodriguez-Pereyra has presented an objection to the co-intension
problem. According to this objection, the examples of properties often cited to
motivate the co-intension problem are actually relational properties, and so turn
out not to be co-intensional. In this essay, I want to revisit Rodriguez-Pereyra’s
objection and explain why I find it defective.
