Imagine logic as a tree. The most fundamental concepts are nearest the trunk with deduction proceeding out toward the leaves. One could say the same for the root system.
The basic construction of logic is that of a conic section, infinitely extended, and connected in two places: at a point where the section is infinitely small and at infinity where the two pieces are infinitely large. [go back to End]
Also, at each node in a branch or root, logic bifurcates into a 'quantitive' and a 'qualitive' stem. So each node has three and only three parts: one incoming stem and two outgoing ones.
With one exception.
At the stem representing a state of 'nothing'.
Here, is the simplest stem and the one most often used, i.e. it is like the trunk of the tree.
Hence, we begin there.
