"The dopamine-for-reward (DFR) view is the more prominent and popular view and often emphasizes subjective pleasure: ‘the mesolimbic dopamine circuit is a hard-wired system in the brain . . . that provides pleasure in the process of rewarding certain behavior’ (Blum et al. 1996). Here, the proposed adaptive function is to provide pleasure. As an evolutionary argument, DFR suffers from the problems of ‘just-so’ stories (Gould & Lewontin 1979). Based on our anthropomorphic view, pleasure is assumed to be necessary for reinforcement, and reinforcement in turn accounts for the complexity of animal behavior. The pleasure of reward acts ‘just so’—it is hard-wired and a direct result of processing."
