In the News (scitation.aip.or): “Mathematicians from Cornell University developed a model that shows which type of thinking, intuitive or rational, typified humanity in different phases of its evolution.
“According to the study, there were times in human history when people who had a slow and rational thinking style ruled, and there were times when rulers were typified by quick and intuitive thinking. According to this mathematical model, it seems that people are not becoming more rational with time, but that rational thinking actually develops cyclically and can be compared to the four phases of economic activity (recession, depression, upsurge, prosperity). The domination of rationality depends on the amount of resources accessible to humanity.”
My Comment: Everything develops according to the four phases of direct Light, according to the four letters of the Creator’s name, “HaVaYaH,” the general and individual schema of the whole creation, of the whole world and every part in it. The Upper Light has to go through the desire (phase zero), the four phases of its spreading (phase one) in order to prepare it and make it available to feel itself and to want to be like the Light itself (phase 2) ,and then to fulfill its desire (phases 3 and 4). Phases 1-4 develop under the influence of the Upper Light.
