The searcher after truth must search with humanity. Ruthless logic is the sign of a limited mind.

His musical inspiration operates in a world uncluttered by conventional bar lines, conventional chord changes, and conventional ways of blowing or fingering a saxophone. Such practical 'limitations' did not even have to be overcome in his music; they somehow never existed for him. Despite this - or more accurately, because of this - his playing has a deep inner logic.

Why all this insistence on the senses? Because in order to convince your reader that he is THERE, you must assault each of his senses, in turn, with color, sound, taste, and texture. If your reader feels the sun on his flesh, the wind fluttering his shirt sleeves, half your fight is won.

what a writer does is to try to make sense of life. I think that's what writing is, I think that's what painting is.

Every song has a composer, every book has an author, every car has a maker, every painting has a painter, and every building has a builder.

It’ll probably be brutal, too. They might even feed you to the dog. He doesn’t have a dog. Yeah, well, he might get one just to feed you to it. She’d never been the kind of person to let something as ridiculous as rational logic interfere with her fear.’ (Alix)

There's a Mr. Hyde for every happy Jekyll face, a dark face on the other side of the mirror. The brain behind that face never heard of razors, prayers, or the logic of the universe. You turn the mirror sideways and see your face reflected with a sinister left-hand twist, half mad and half sane.

Women belong at home, fulfil their life through motherhood, by caring for their husbands and serving them.
