Ancient Greek Philosopher, Aristotle was interested in learning everything he could about the nature of life. He used the word “Psyche” to refer to the essence of life. Indeed, the term Psychology comes from two Greek words ‘Psyche and Logos’. ‘Psyche’ means soul or mind and ‘logos’ means talk. Therefore, the literal meaning of the words Psychology is study of soul or mind.
