In theoretical as well as applied psychology, no term is more misleading, or confusing, than the term consciousness. We use the term often in our conversation; we come across it in our study; but when we are asked to define it properly, to explain its significance, its meaning, or the idea for which that word stands, we are unable to do so.
And that is because there are so many varied ideas concerning consciousness. There are so many aspects of consciousness, there are so many states of consciousness that we get mixed up - that is, we confuse one with the other. So we must know thoroughly the true significance of the term. Then we can make such distinctions as inner consciousness and outer consciousness.
