From the Z-papers by Herb Zinser

Z-Paper 584  provides some data about Nature's SYMBOL MACHINE comprised of  nouns,verbs, concepts, math equations,  flowcharts, etc.  The ideas found in math and science textbooks are part of the SYMBOL MACHINE.

Using Galileo's suggestions  of  " 2 CHIEF WORLD  SYSTEMS"   we now perceive Sartre existentialism as partitioned into 2 or more data spaces....... the  2  CHIEF existential entities

1) physical reality of objects: concrete highways, iron  automobiles, cellulose trees, humanoids, etc.
2) The world of symbols, concepts, process control system flowcharts, biochemistry diagrams,  math and physics equations, etc.

Thus we understand Charles Dickens " TALE of 2 Cities".

Language in Thought and Action, S.I. Hayakawa.
Chapter 2 Symbols Maps and Territories
There is a sense in which we all live in two worlds.

Thus we have the source domain of SYMBOL LIFE and thought that may get mapped to the destination range of physical biology with human activities of the geography surface of EARTH.
