“Everything has altered its dimensions, except the world we live in. The more we know of that, the smaller it seems. Time and distance have been abridged, remote countries have become accessible, and the antipodes are upon visiting terms. There is a reunion of the human race; and the family resemblance now that we begin to think alike, dress alike, and live alike, is very striking. The South Sea Islanders, and the inhabitants of China, import their fashions from Paris, and their fabrics from Manchester, while Rome and London supply missionaries to the ‘ends of the earth,’ to bring its inhabitants into ‘one fold, under one Shepherd.’ Who shall write a book of travels now? Livingstone has exhausted the subject. What field is there left for a future Munchausen? The far West and the far East have shaken hands and pirouetted together, and it is a matter of indifference whether you go to the moors in Scotland to shoot grouse, to South America to ride and alligator, or to Indian jungles to shoot tigers-there are the same facilities for reaching all, and steam will take you to either with the equal ease and rapidity. We have already talked with New York; and as soon as our speaking-trumpet is mended shall converse again. ‘To waft a sigh from Indus to the pole,’ is no longer a poetic phrase, but a plain matter of fact of daily occurrence. Men breakfast at home, and go fifty miles to their counting-houses, and when their work is done, return to dinner. They don’t go from London to the seaside, by way of change, once a year; but they live on the coast, and go to the city daily. The grand tour of our forefathers consisted in visiting the principle cities of Europe. It was a great effort, occupied a vast deal of time, cost a large sum of money, and was oftener attended with danger than advantage. It comprised what was then called, the world: whoever had performed it was said to have ‘seen the world,’ and all that it contained. The Grand Tour now means a voyage round the globe, and he who has not made it has seen nothing.”

The trial of Charles B. Reynolds for blasphemy (1887)
Context: I want you to understand what has been done in the world to force men to think alike. It seems to me that if there is some infinite being who wants us to think alike he would have made us alike. Why did he not do so? Why did he make your brain so that you could not by any possibility be a Methodist? Why did he make yours so that you could not be a Catholic? And why did he make the brain of another so that he is an unbeliever — why the brain of another so that he became a Mohammedan — if he wanted us all to believe alike?
After all, maybe Nature is good enough and grand enough and broad enough to give us the diversity born of liberty. Maybe, after all, it would not be best for us all to be just the same. What a stupid world, if everybody said yes to everything that everybody else might say.
The most important thing in this world is liberty. More important than food or clothes — more important than gold or houses or lands — more important than art or science — more important than all religions, is the liberty of man.
