The next shift in consciousness took place between 10,000 B.C. and 500 B.C. This was the transition to the Mental structure of consciousness. It was at this time that humans, to use Gebser's image, stepped out of the mythical circle (two-dimensional) into three- dimensional space. Mythology had become so deficient (and it should be noted that each structure has its "efficient" as well as "deficient" form), that humankind needed a clean break with the past. The plethora of gods and contradictory stories of creation, formation of institutions, and so on threatened to overwhelm the consciousness of the individual; he practically stood on the verge of drowning in a deluge of mythological mentation. In reaction to this, Socrates, Plato, Aristotle, and of course, Pythagoras stepped forth to counteract this trend. The mental structure was inaugurated and this coincides with the "discovery" of "causality," Abstraction becomes a key word to describe mental activity and we find man using his mind to overcome and "master" the world around him. With abstraction comes philosophizing, hence the philosopheme is the primary form of expression. Monotheism almost universally replaces the plethora of gods of bygone days; dogma, in both allegory and creed, replaces the symbols of previous times; method replaces the mysteries as humanity develops an ever-increasing desire to penetrate, and, of course, master nature. This has given rise to the idea of science as the dominant religion of today. Also at this time, time itself was conceptualized (spatialized) as an "arrow" that points from the past to the future by way of the present (Feuerstein, 1987, p98).
About the time of the Renaissance, humanity came into its own and really mastered space. It was at this time that perspective was actually introduced into art. Since that time, perspective has come to be a major part and aspect of our mental functioning. Perspective is the life blood of reasoning and the Rational structure of consciousness, which Gebser considers to be only a deficient form of the Mental structure. What we have is the full development of the ego and its related centeredness. We conceive things, events and phenomena in terms of our own perspectives, often at the expense of others. The eye, it will be seen (and the last of the openings in the head), becomes the spiritual organ representative of this structure. Our language, our entire imagery and dominant metaphor takes on visual, spatial character. Space is finally overcome, in the true sense of the word. With the supercession of space, the person finally accomplishes his/her egoistic, individual separation from nature. In this concretization of the "I," we become very aware of our existence, of our beingness, of our individuality. And so it should be. But in a deficient mode, the outcomes, of course, are loneliness, isolation, and alienation, which are so characteristic of our own American culture. In fact, our current materialistic approach to understanding reality is perhaps the final stage of this structure. There is also much everyday evidence to indicate that we are moving through a great change at this time.
We should remember, however, that this is also the time of philosophy. The mental ordering and systematization of thought becomes the real dominant mode of expression. The myths have lost their vibrancy and existential connection to reality. Greek thought followed later by the Scholastics and finally the Enlightenment are all periods in which this particular structure of consciousness flourishes and strongly manifests. It is not without its opposition, of course, since any change will bring about the requisite opposition to its own development. By the time of the Renaissance, though, this structure had firmly established itself and was prepared to move into the next phase of its development. At this time, as was pointed out earlier, a very profound and significant event occurred: man incorporated space into his thought. We cannot underestimate, or overstate, the importance of this development. It is literally at this time that the world begins to shrink. The seeds of our one world community are planted at this time. The ripples begun during the magical structure are widening significantly: first spirit, then soul, now space have become constituents of man's consciousness. Three dimensions have been established and we are prepared for the next significant step we are taking now.
