I have agreed, to a large extent, with the points Harkness makes in his commentary. I have however also sought to suggest a more pluralistic perspective on scientific explanation. This ensures that the free energy principle, as it applies to the neural organ, has great potential to explain many aspects of the mind. I went one step further, however, and suggested that behind this explanatory pluralism lies a unified, Bayesian account of explanation, which perfectly mimics the unifying aspects of the free energy principle itself.
