The holons.org web site is about waking up from the sleep of everyday life. There have been many things in my life that have helped awaken me from that sleep: people, places, events, activities, books, movies, etc. The technical psychological meaning of "the sleep of everyday life" is consensus consciousness trance as described in Charles T. Tart's book Waking Up.
"Whole atoms are parts of molecules; whole molecules are parts of cells; whole cells are parts of organisms, and so on. Each whole is simultaneously a part, a whole/part, a holon. And reality is composed, not of things nor processes nor wholes nor parts, but of whole/parts, holons."
"A new perspective on whole-part relationships is taking shape around the concept of the holon - a term coined by Arthur Koestler to designate that which is simultaneously a whole in its own right and a part of a larger whole. An atom is a whole in itself. When it is also part of a molecule it becomes a holon, or a whole-part. The molecule that is also part of a cell is a holon, as is the cell that is part of an organ, and so on. This hierarchy of relationships from the atom to the organism is known as a holarchy. The concepts of holon and holarchy are fundamental to understanding the healthy function of complex living systems, which requires that each of their whole-parts maintain its own identity and boundaries even as it functions as part of the larger whole."
