The last volume of Chesterton's collected essays, Gathered from the London Mercury, the New Witness, and the Illustrated London News, it is the only volume from after WWI, and is most serious, philosophical, and socially direct collection.

"The problem is not so much Prohibition with a large P as prohibition with a small one. I mean, I am interested not so much in liquor as in liberty. I want to know on what principle the prohibitionists are proceeding in this case, and how they think it applies to any other case. And I cannot for the life of me make out. They…do not attack liquor; they do quite simply attack liberty. I mean that they are satisfied with saying about this liberty what can obviously be said about any liberty – that it can be, and is, abominably abused. If that had been a final objection to any form of freedom, there never would have been any form of freedom."

"So long as we combine ceaseless and often reckless scientific speculation with rapid and often random social reform, the result must inevitably be not anarchy but ever-increasing tyranny. There must be a ceaseless and almost mechanical multiplication of things forbidden. The resolution to cure all the ills that flesh is heir to, combined with the guesswork about all possible ills that flesh and nerve and brain-cell may be heir to – these two things conducted simultaneously must inevitably spread a sort of panic of prohibition. Scientific imagination and social reform between them will quite logically and almost legitimately have made us slaves."
