There are some words which I have known since I was a schoolboy. “With the first link, the chain is forged. The first speech censored, the first thought forbidden, the first freedom denied, chains us all irrevocably.” These words were uttered by Judge Aaron Satie — as a wisdom, and warning. The first time any man’s freedom is trodden on, we’re all damaged.
