In A World We Share, Roger Berkowitz reveals how Han­nah Arendt’s remark­able and often strained friend­ships shaped her rad­i­cal claim that friend­ship, not truth, is the foun­da­tion of the polit­i­cal bonds that hold us togeth­er. This illu­mi­nat­ing book offers a time­ly med­i­ta­tion on lone­li­ness, plu­ral­i­ty, friend­ship, and demo­c­ra­t­ic life in an age of polarization.
