“The imagination is the spur of delights... all depends upon it, it is the mainspring of everything; now, is it not by means of the imagination one knows joy? Is it not of the imagination that the sharpest pleasures arise?”

“Is imagination dependent upon experience, or is experience influenced by imagination?”

“To know is nothing at all; to imagine is everything.”

“On Memory: Imagine a desk covered with papers. That is everything you are thinking about. Now imagine a stack of file drawers behind it. That is everything you know. The trick is to keep the desk and the file drawers as close to one another as possible, and the papers neatly stacked.”

“It is not that what you can imagine depends on what you know, but that what you know depends on what you can imagine. The history of science couldn't be clearer on this point, and, therefore, Dennett is a sophist.”

“If having an imagination means imagining all the things you don't have - imagining, in fact, the impossibility of your own happiness - is an imagination a good thing?”
