This paper investigates whether there is an acceptable version of Functionalism that avoids commitment to second-order properties. I argue that the answer is “no”. I consider two reductionist versions of Functionalism, and argue that both are compatible with multiple realization as such. There is a more specific type of multiple realization that poses difficulties for these views, however. The only apparent Functionalist solution is to accept second-order properties.
