Regardless of being one of the slightly weaker episodes of season two, "The Mind and the Matter" definitely does demonstrate again how progressive, accurate and relevant Rod Serling's "The Twilight Zone" really was. This short story was made in the early 60s, and already it deals with topics like overpopulation versus social isolation. We are more than half a century later now, and the issue only got catastrophically worse. Our poor and asocial protagonist Mr. Archibald Beechcroft would instantly throw himself off a bridge if he saw how many people there are nowadays! Beechcroft doesn't like people. He hates being pressed against them like sardines in the subway on his way to work every morning, he hates having to step into a crowded elevator and he hates the loudness of the co-workers at the office. But then, Beechcroft receives a spiritual book from his obtrusively gentle colleague Henry, entitled "The Mind and the Matter", which teaches him to get rid of people simply by the power of intense concentration. Although ecstatic at first, Beechcroft rapidly realizes that completely solitude isn't ideal, neither. I personally rate "The Mind and the Matter" much lower than the vast majority of "Twilight Zone" episodes, simply because it's so silly and doesn't feature the least bit of unsettling atmosphere and/or mystery. Shelley Berman's performance is solid, I reckon, and the scenes with all his nagging and complaining doppelgangers is quite funny.
