One problem that atheists have yet to solve is ethics (how people should treat one another). To this point, all ethics have been based on beliefs--"believ[ing] something without proof." Beliefs can be secular as opposed to sacral, but to privilege either over the other is purely arbitrary, and as John Locke (among others) realized, in matters related to relations among human beings arbitrariness is injustice.

An ethic that followed from observation within material existence would resolve that issue. As it happens, I have discovered one. Both in theory and practice it would take us "Beyond Liberalism" (here in Medium but not behind the paywall).
