My first duty to write a gripping yarn. Second is to convey credible characters who make you feel what they feel. Only third comes the idea.
All this talk of using tax policy to 'assess social costs'...what a dumb idea. The only way to stop polluters is to put them against walls and shoot them.
It's how creativity works. Especially in humans. For every good idea, ten thousand idiotic ones must first be posed, sifted, tried out, and discarded. A mind that's afraid to toy with the ridiculous will never come up with the brilliantly original.
