People seeking to be up-to-the-minute often indulge in such redundancies as “in today’s modern society” or “in the modern society of today.” This is empty arm-waving which says nothing more than “now” or “today.” A reasonable substitute is “contemporary society.” Such phrases are usually indulged in by people with a weak grasp of history to substitute for such more precise expressions as “for the past five years” or “this month.”
See “from the beginning of time.”
