Is there evidence for the unconscious mind?

Now I want to say something, which will perhaps surprise you.

There is a man who wrote a book called the Law of Psychic Phenomena―author, Thomas Hudson, says certain things about those two parts of the mind, which he called the subjective and the objective. 

He said that the subjective mind was incapable of inductive reasoning―that the subjective mind would accept any premise given it by the objective mind and would reason from that premise with matchless logic, but that it could not go behind the premise―that it could not reason backwards.
