Therese's character and the early experiences that shaped her have been the subject of analysis, particularly in recent years. Apart from the family doctor who observed her in the 19th century, all other conclusions are inevitably speculative. For instance, author Ida Görres, whose formal studies had focused on church history and hagiography, wrote a psychological analysis of the Therese's character. Some authors suggest that Therese had a strongly neurotic aspect to her personality for most of her life. Harrison concluded that, "her temperament was not formed for compromise or moderation … a life spent not taming but directing her appetite and her will, a life perhaps shortened by the force of her desire and ambition."
