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. The most improbable tales can be made believable, if your reader, through his senses, feels certain that he stands at the middle of events. He cannot refuse, then, to participate. The logic of events always gives way to the logic of the senses.

To make music means to express human intelligence by sonic means. This is intelligence in its broadest sense, which includes not only the peregrinations of pure logic but also the "logic" of emotions and intuition.

Stories are there to be told, and each story changes with the telling. Time changes them. Logic changes them. Grammar changes them. History changes them. Each story is shifted side-ways by each day that unfolds. Nothing ends. The only thing that matters, as Faulkner once put it, is the human heart in conflict with itself.

My mother carefully fostered a liking for botany, giving me a small microscope and many books, which I yet have. Strange as it may seem, I now believe that botany and the natural system, by exercising discrimination of kinds, is the best of logical exercises. What I may do in logic is perhaps derived from that early attention to botany.

It's the unlikely juxtaposition of creativity and logic which causes the wooliness and confusion around the term 'innovation'.

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.

Certain issues in philosophy of science (having to do with observation and the definition of a theory's empirical import) had beenmisconstrued as issues in philosophy of logic and of language.

This is not at all new, but is the traditional nominalist line.
