I think that the current perspectives make "more sense" because they are more thoroughly researched and have the benefit of psychological studies combined with advanced technology to back them up. However, I feel that it is impossible to appreciate the current psychological perspectives without understanding and learning about the historical ones. When compared, it is easy to see how far psychology has advanced over even the last 100 years.
Psychology is a field that is always changing and growing; there will always be a new theory and/or a new discovery, much like in the medical field. As psychologists improve their methods of study, their research becomes more scientific in nature, which makes it more reliable and provides more strength for the current perspectives.
