According to Osho, stupidity isn’t a comparative trait between people; it is the very nature of the mind itself. Whether full of information or blank, the mind is asleep, identified with memory and past—hence stupid. Intelligence appears only when awareness awakens beyond mind, in self-knowing presence. So the real divide isn’t more-or-less stupid, but asleep versus awake, reaction versus responsive here-now seeing.
We all look “stupid” when lost in our minds; real smartness comes from waking up and being fully aware right now.
