Yin and Yang

Yin	Yang

Yin and yang are the basic elements of all information. Their names and associations are not important; what is important is their capability of differentiation, their power of splitting the cosmic egg.

Conventionally, yang represents activity and yin represents passivity. From these basic choices, several other pairs of associations can be derived:

yang	yin	explanation
up	down	Passive (yin) objects follow gravity; going against gravity requires activity (yang).
heaven	earth	Heaven is above (yang); earth is below (yin).
air	earth	Air is the Hellenistic element of the sky/heaven (yang).
blue	yellow	Blue is the color of the sky (yang). Human vision contrasts blue with yellow, which is a common color of the earth (yin).
light	heavy	Heaviest objects sink the deepest (below, yin); lightest objects float on the surface (above, yang).
bright	dark	An object that emits radiation is more active (yang) than one that does not.
hot	cold	A hot object radiates (yang) its heat.
fast	slow	Passive (yin) either does nothing or does something very slowly.
young	old	Slow (yin) changes take long time; long changers last long.
fire	water	Fire is brighter, hotter, less stable and more active (yang) than water (the remaining Hellenistic element).
stars	planets	Stars emit radiation (yang); planets receive it (yin).
lack	satisfaction	Lack causes activity (yang) to fulfill the need.
odd	even	Even numbers are "satisfied" (yin), with each element having a companion. Odd numbers lack (yang) a companion.
one	zero	The numeral associations of the modern binary system. One is odd (yang), zero is even (yin).
one	two	The numeral associations of the ancient gua-based binary systems.
difficult	easy	Passivity (yin) is easier than activity (yang); the easiest things require no activity at all.
complex	simple	Activity (yang) forms complexity; passivity (natural decay, yin) destroys complexity.
limited	unlimited	Complex and difficult (yang) things have more boundaries (information) than simple and easy things. The simplest things (yin) have no differentation or defined limits at all.
left	right	For most humans, the right hand is easier (yin) to use than the left hand.
east	west	East, the direction of sunrise, is associated with fire (yang), the element of the sun.
outward	inward	The interior of Earth is below (yin).
south	north	If west is right and east is left, then south is forward, which is upward in the normal human field of vision (when watching the earth).
hard	soft	Hard objects use activity to resist the hits, while soft objects adjust themselves to the hits.
clockwise	counter-clockwise	If west is right and east is left, then the sun seems to traverse clockwise. This is seen as more natural (yin) than the counter-clockwise movement.

For other possible associations reachable by different justifications, study the ten dualisms of Pythagoreanism, or the Chinese associations of yin and yang.
