Some critics find that Thomas Reid thinks the mind especially problematic, "hid in impenetrable darkness". I disagree. Reid does not hold that mind, more than body, resists explanation by the new science. The physical sciences have made great progress because they were transformed by the Newtonian revolution, and the key transformation was to stop looking for causes. Reid's harsh words are a call for methodological reform, consonant with his lifelong pursuit of a science of mind and also with his frequent (though overlooked) optimism about such a science.
