Origin of mindless

before 1000; Middle English myndles, Old English gemyndlēas. See mind, -less

Explanation

Mindless things are done without any care or thought.

If something's careless or lacks reason, you can describe it as mindless, like the casual, mindless violence on a TV show. A mindless task is one that you can do without even thinking about it, like sweeping the sidewalk or stuffing fliers into envelopes. Mindless comes from the Old English myndleas, "foolish or senseless."
