“Proper punctuation is both the sign and the cause of clear thinking.”

“We have a language that is full of ambiguities; we have a way of expressing ourselves that is often complex and elusive, poetic and modulated; all our thoughts can be rendered with absolute clarity if we bother to put the right dots and squiggles between the words in the right places. Proper punctuation is both the sign and the cause of clear thinking. If it goes, the degree of intellectual impoverishment we face is unimaginable.”

“If this satanic sprinkling of redundant apostrophes causes no little gasp of horror or quickening of the pulse, you should probably put down this book. By all means congratulate yourself that you are not a pedant or even a stickler; that you are happily equipped to live in a world of plummeting punctuation standards; but just don't bother to go any further.”

“The reason it's worth standing up for punctuation is not that it's an arbitrary system of notation known only to an over-sensitive elite who have attacks of the vapours when they see it misapplied. The reason to stand up for punctuation is that without it there is no reliable way of communicating meaning.”

“Part of one's despair, of course, is that the world cares nothing for the little shocks endured by the sensitive stickler. While we look in horror at a badly punctuated sign, the world carries on around us, blind to our plight. We are like the little boy in The Sixth Sense who can see dead people, except that we can see dead punctuation. Whisper it in petrified little-boy tones: dead punctuation is invisible to everyone else -- yet we see it all the time. No one understands us seventh-sense people. They regard us as freaks. When we point out illiterate mistakes we are often aggressively instructed to "get a life" by people who, interestingly, display no evidence of having lives themselves. Naturally we become timid about making our insights known, in such inhospitable conditions. Being burned as a witch is not safely enough off the agenda.”

“...punctuation marks are the traffic signals of language: they tell us to slow down, notice this, take a detour, and stop.”

“Truly good manners are invisible: they ease the way for others, without drawing attention to themselves. It is no accident that the word "punctilious" ("attentive to formality or etiquette") comes from the same original root as punctuation.”
