The apolitics of people.
The Greek word [idiot] originally did not even contain a hint of mental illness. In ancient Greece, it referred to the “private person,” the “separate, isolated person.” It is no secret that the ancient Greeks treated public life very responsibly and called themselves "polytes". Those who avoided participation in politics (for example, did not go to the vote) were called "idiot" (that is, occupied only with their own personal narrow interests). Naturally, “idiots” were not respected by conscious citizens, and soon this word grew into new disregarding shades – “limited, underdeveloped, ignorant man.” And already in the Romans, the Latin idiota means only "ignorant, ignorant", from where two steps to the meaning of "stupid".
