Whether they term it idealism outright, the editors write a lot about the Forms (capitalized, big-deal abstractions they thought were primary to the imperfect versions we can observe with the senses).  This basic Western, Platonic approach informs many of our topics.  For instance, it’s a Platonic move to have lawyers and judges inferring what the Founders might have thought of assault weapons or privacy.  The Form (their thinking then) is being used to decide court cases on issues impacting us.
