 This kind of an explanation is a nice try, and plausible, but it is rather speculative. That our minds really developed this way in light of those pressures is a question that is not easy to answer from the armchair. Maybe the facts do have a different structure, but our forms are close enough for practical purposes, i.e. for survival and flourishing. And maybe the correspondence does obtain, but not for this largely evolutionary reason, but for a different, more direct and more philosophical or metaphysical reason.
