Psychology is a product of early 20th century interest in studying the soul and the mind. The word psychology has its origins in Greek words meaning “the study of the soul.” As scientific methods — focus on the measurable — became the focus of study, Psychology abandoned the immaterial, immeasurable soul, calling it the purview of Religion, and focused on behavior, which is measurable. With that, we lost the understanding that a soul at peace would generate different behaviors than a soul in turmoil. We lost focus on the spiritual source of thought and started defining people by the outcomes of their thinking. The Principles bring us back to the Source, a Feeling of deep connection to the universe.
