How do the following statements show that Hawthorne had psychological insights that were far in advance of his time?A. "Wherever there is a heart...

We now understand what is often called the "Mind-Body Connection," which explains how our physical conditions might be affected by our emotional or spiritual states.  Even though Hawthorne did not have our modern vocabulary to discuss this, there is no question that he was explaining what Freud would have called the subconscious or the unconscious.  He had insight into the results of a puritanical and sexually repressive society, many years before Freud posed his theories, and an understanding that physical manifestations might be rooted in our minds and hearts. 

There is considerable research to substantiate Hawthorne's statements.  For example, people who are depressed are more prone to physical ailments, and people who are prayed for seem to recover more quickly.  These are just two examples that come to my mind quickly, and I am sure others will be able to offer examples, too.

I do want to caution you, though, that this idea can be taken too far and be damaging in its application.  For example, women were often accused of being witches when they had unusual physical characteristics, which were thought to be reflections of spiritual deficiencies.  Hawthorne's ancestors played a large part in earlier witch trials, something that we think troubled Hawthorne considerably. Similarly, today, people who get cancer are often accused of not having enough good thoughts, of not being able to visualize good health, or of becoming sick because they insist on being depressed.  So you see, there is a certain amount of blame that can be attached to this "Mind-Body Connection." 

Nevertheless, it is important to bear in mind that our bodies, minds, and hearts are inextricably intertwined and that the connections should be respected.  In this, Hawthorne anticipated the great theorists to come.
