In the 18 th  century, psychology was understood as the ‘Science of Mind’. William James (1892) defined psychology as the science of mental processes. But the word “mind” is also quite ambiguous as there was confusion regarding the nature and functions of mind. Modern psychologists defined psychology as the “Science of Consciousness”. James Sully (1884) defined psychology as the “Science of the Inner World”. Wilhelm Wundt (1892) defined psychology as the science which studies the ‘internal experience’. But there are three levels of consciousness – conscious, subconscious and the unconscious and so this definition also was not accepted by some people.
