Now I am baffled! In what way is the Oxford English Dictionary wrong, for all I did was point out that the word "cheap" simultaneously has diametrically opposed meanings.
Well, since you asked.
Dictionaries give meanings; they don't lay down rules but merely tell us that a word means this, or that, or in some cases this AND that, and then leave it for us to use as we freely see fit.
You use 'cheap' to mean tawdry. So do I, as it happens. But as dave8h says, it's all about context. "I want cheap housing" doesn't mean that I want tawdry, sub-standard housing. It means I don't want expensive housing.
So, we - well, as I can only speak for me - I thought you were wrong in your attempt to turn a discussion of possibilities into one of rights and wrongs.
And poetry? Perhaps this does point up a difference in approaches to problems, and to life, and divides us into those inclined to the arts, and those inclined to the sciences. Don't misunderstand me, I see a scientific approach to life as vital; without it we would still be reading chicken's entrails or consulting the stars. But even scientists need art; they need vision, flights of fancy, free imagination.
They need to sit in their laboratories and wonder 'Suppose I stuck an electric motor on that bike? Silly idea, but just suppose it worked.' It worked, giving thousands of us who have very little idea exactly HOW it works a new dimension of delight to our lives.
