Let's not pretend that mental phenomena can be mapped on to the characteristics of billiard balls. - Gregory Bateson

Finally, in the dim region where art, magic, and religion meet and overlap, human beings have evolved the “metaphor that is meant,” the flag which men will die to save, and the sacrament that is felt to be more than “an outward and visible sign, given unto us.” Here we can recognize an attempt to deny the difference between map and territory, and to get back to the absolute innocence of communication by means of pure mood-signs.

We can never be quite clear whether we are referring to the world as it is or to the world as we see it.

Science, like art, religion, commerce, warfare, and even sleep, is based on presuppositions. It differs, however, from most other branches of human activity in that not only are the pathways of scientific thought determined by the presuppositions of the scientists but their goals are the testing and revision of old presuppositions and the creation of new.
