How do you understand people?

Psychology is the latest science. It is considered the strongest today and the most pervasive in all aspects of life. Not long ago, this science was a branch of philosophy, or rather a tail of it, then it became independent, and its foundations continue to strengthen and strengthen until it has become the basis for other sciences that it had been a shadow of in the past.
Perhaps the secret of this development most likely stems from understanding the meaning of "psychology" in the correct manner, or more precisely, stems from understanding that "soul" on a more precise and clearer truth and less ambiguous and ambiguous, the meaning of the word "psyche" in Greek, the spirit - so it is "science." The "soul" is the science that investigates that "thing" that wears the body and gives it the quality of life. The belief at that time was that the "soul" was a thin, transparent, hidden substance, having a relationship with the air just as air has a relationship with matter. The belief was that it had the ability to penetrate bodies while retaining them. With its being and its ability to separate. When Plato came, he refused to accept this idea, the idea that the soul is "matter," and said that it is something that the senses cannot perceive, but to which the mind can be guided.
